DESCRIPTION:
On December 17, 1996, the City Council awarded a contract to Advanced Micronet Solutions (AMS).
Per City Council instructions, AMS designed several types of Internet communications systems. The
proposed systems have varying degrees of capabilities and costs. This advanced the project from the
program included in the 1996 - 2001 Capital Improvement Plan (CIP). The project as identified in the
CIP was scheduled for Fiscal Year 1998/99 and it was to also address the need for an external gateway
which could provide a dial-up access for faxing and dial-up services such as the IRS and financial
institutions. The external gateway component is addressed at the end of this report.
IDENTIFIED INTERNET USES
At this time, the City does not have a fully detailed plan for the use of the Internet. In addition the
technology changes rather rapidly and may affect the future needs for Internet access for all City
Departments. Some of the initial uses which can be supported under any of the alternatives presented
indude: transfer of documents to the firm maintaining the City's website; e-mail communications for the
public; research of issues related to current Staff projects; and sharing of documents between other
agencies and contract consultants.
It is expected that the improvements contained as part of this report will be the first step towards the use
of the Internet by City Staff. In the future, consideration of emerging technologies, such as completing of
business transactions electronically, will require a change from the approach recommended at this time.
Staff believes that an incremental approach to implementation is warranted and that the system design
should address currently identified needs.

PRIMARY ALTERNATIVES EVALUATED FOR INTERNET ACCESS:
The Internet can be used in several ways. For the most part, cities use the Internet to access their web sites
and to send and receive limited e-mail communications. When the use of the Internet is limited to these
basic functions and the number of workstations with access to the Internet is less than 20, less '.
comp:~cate~ e~uipment is ~equired. ~is type. of lo,:-~apacity system is proposed below as "Design-A.....
ISDN , which IS presented ill more detaIl later In ExhibIt I. .
The ISDN design alternative is an improvement over the standard dial-up access used by most single
access home Internet users. The ISDN design improves the speed of access as compared to a modem and
offers access to multiple users in a cost effective manner. Fewer individual communications lines are
required with a group of ISDN workstations sharing a single connection.
The second approach evaluated provides desk-top access to the Internet for all workstations on the Civic
Center Network and requires a more complicated approach. In this approach each Network User would
have an Internet E-Mail account which could be accessed in similar fashion to the City E-Mail system at
their desktop. This type of system provides a high-capacity system, that may in the future accommodate
.expansions to transact business electronically, provided that the technology has not changed from what is
currently available. Design B-1, described in Exhibit 1, proposes equipment configurations, including an
Internet server, which would be on-site and would need to be supported by City Staff. This alternative
does allow the City to host its own website, since a second computer server is required.
The Consultant also evaluated related systems, which would be either an enhancement to the Frame Relay
option (i.e. Proxy Server and Firewall) or they represent recommendations to address more efficient
operation of the data processing needs. These items are also detailed in Exhibit 1.

Consultant Executive Summary (Exhibit 2) contains an overview of Design A: ISDN and Frame Relay

has taken the information prepared by the Consultant and evaluated the designs, paying close attention to "
the following key areas:
. Up-Front Cost To Implement the System

As shown, the ISDN alternative has the lowest initial cost and only a slightly higher on-going operating
cost. However, the One-Time Cost for the Frame Relay alternative is significantly higher and it would
take several years to recover the difference from any savings in operating costs. As discussed in Exhibit
1, the Frame Relay alternative could save in expenditures for Web hosting service charges, however, even
factoring in this savings the cost of alternative A - ISDN remains less costly for at least a 5 year period.
The Frame Relay Alternative B-1 has an obvious advantage in its ability to fully meet the identified needs
for use of the Internet. This alternative provides easier access by allowing each workstation a connection
and by providing greater speed in the transfer of computer files. The ISDN alternative does have
limitations in that Internet Access would need to be shared within Departments at certain workstations.
Also, the transfer of data would be slower than the Frame Relay alternative. However, both options
would address the current identified uses for the Internet.
The consideration of possible future applications is the place where the ISDN option presents the most
significant limitations. This includes the fact that that this system would not be scaleable (i.e. it cannot be
easily upgraded if additional capacity is needed or there is a desire to utilize more advanced applications
of the Internet). Additionally, since ISDN is a dial-up circuit, it has proven to be less reliable than a
leased line. These known limitations are relevant in making a decision on the selection. Although from
their professional opinion AMS believes that the Frame Relay option would provide the most flexibility,
Staff believes that it may be premature to make this investment at this time. It would appear to be more
prudent to implement the use of the Internet in a cost effective manner and allow for use of the technology
and a more refined statement of the applications to be considered.
The decision to proceed with either alternative will also have an impact on the ability of Staff to support
the Data Processing function. The Civic Center Network has incrementally grown to address a variety of
needs for the organization. Initially the network provided a source of standardized word processing,
spreadsheet; sharing of documents between workstations; and electronic mail functions. These element
have been expanded to include the addition of: remote connection to Shannon Center, with new Program
Registration Software; Engineering Workstation for Computer Aided Design; etc. Inherent with an
Internet connection will be a need for more time to support the computers on the network and to assist the '
users. This issue is also addressed in a separate Agenda item.
EXTERNAL GATEWAY
As noted at the beginning of the report, the original intent of this CIP was to also address the needs in
some parts of the organization to have dial-up modem access separate from an Internet connection. For
example, the IRS will be requiring the City to move towards electronic filing of quarterly tax payments.
Another example is a PERS option which allows reporting to be transmitted electronically.
Obviously the simplest manner in which to address this need is to buy a separate modem and a phone line
for those workstations which have this need. However, in discussions with the Consultant it was
determined that greater efficiency may be achieved by having a shared modem. This would provide dial-
up access from more workstations and would also allow for faxing from these workstations. It is
anticipated that in-coming faxes would continue to be received on the existing fax machines. The
estimated cost to complete this option is $6,510 which is broken down as follows:
Equipment
Software
Installation/W orkstation Configuration
One-Time Pacific Bell Charges
Sub-Total One-Time Costs
$ 2,500
1,810
2,000
200
$ 6,510
In addition to the one-time costs there would be telephone operating costs for two lines estimated at
approximately $480.00 per year. .
The proposed equipment can act as a shared modem and selected workstations would be configured to
access the modem. The software purchased would allow for up to 20 machines to be configured with out-.'" .-
going fax capability from the desk-top. This would provide greater efficiency in distributing out-going
faxes. Currently there are 3 fax machines located at the Civic Center and some Departments must make
arrangements for counter coverage in order to physically go to the machine and transmit the document.
This would allow the fax to be sent directly from the workstation and more widely distribute access to fax
capabilities; In order to implement the CIP project as originally conceived it is recommended that this
option also be pursued at this time.
RECOMMENDATION
Based upon this analysis, Staff recommends that at this time the ISDN - Design A alternative be
implemented along with the external gateway. It is recognized that in the future other technologies and 1
or proposed uses of the Internet may dictate a future change in the method of accessing the Internet. This
could result in some of the equipment being in place for a shorter time than the minimum 4-5 year life
cycle currently used for computer equipment. This approach will assure that the design of any future uses
for Internet access are designed at the time that the need is identified and that they take into consideration
current technology.
A Budget Adjustment will be required to proceed with this projed. The Following lists the costs in detail:

A total of $13,060 would need to be appropriated in both the Capital Project and the Operating Budget to
accommodate the Internet Capital Project in the current Fiscal Year. The monthly service costs are
proposed to be budgeted in the Administrative Services Department Budget. A budget adjustment of
$635 is recommended to address the final one month of the current Fiscal Year. Staff would include the
full year operating cost in the proposed 1997/98 Fiscal Year Budget. The full annual operating cost will
be approximately $7,620. A proposed Budget Change is attached as Exhibit 3.

DETAILED DESCRIPTION OF ALTERNATIVE SYSTEM DESIGNS
DESIGN A: ISDN CIRCUIT
ISDN is a data line which transmits data in a digital format. Digital data moves much faster over the
Internet then is possible with a typical analog telephone line and modem used by most home users. Due
to the speed and capacity of an ISDN data line, it has become increasingly popular for Internet
communications for single users and small organizations. One of the anticipated initial uses for the
Internet is the sharing of documents with other agencies. Therefore, the speed at which documents can be
retrieved is somewhat important to the efficient integration of the Internet into City operations.
Theoretically, up to 20 users can access the Internet simultaneously over a single ISDN line; however, as
the number of simultaneous users increase, the speed of transmission declines. In practice, an ISDN line
allows three simultaneous users before performance drops. Since the Internet is anticipated to be used
initially for intermittent tasks, it does not appear that the number of consecutive users would be a problem.
In addition, more than 3 simultaneous users can be on the Internet although they may note a decrease in
the speed.
As proposed in Design A: ISDN, 20 existing workstations will be configured to have Internet access.
Although Staff has not fully examined the needs of each department, the following number of Internet
workstations could be distributed in each Department without exceeding 20 users:
DEPARTMENT 1 PROGRAM
City Manager 1 City Clerk
Administrative Services 1 Finance
Parks & Community Services
Police Services
Economic Development
Community Development
Public Works 1 Engineering
# WORKSTATIONS

The precise allocation of the workstations to be configured would be subject to further review based upon
each department's demonstrated need for a connection. At a minimum one connection would be retained
for each Department, as the design of the City Website will include an E-Mail Form. For example,
someone can E-Mail directly to the Public Works Department about a particular issue or topic. The initial
costs associated with this alternative are outlined in the section which follows.
EQUIPMENT AND LABOR:
The required equipment consists of two routers. With maintenance warranties, the total equipment cost is
approximately $1,500. The most significant initial cost is associated with the labor required to modify the
program configurations on the individual workstations. Each workstation must be loaded with software
and configured to operate with its designated router. The labor cost to install the routers and to configure
20 workstations is approximately $3,120.
The total initial estimated capital cost to install this alternative is approximately $4,620.
OTHER ONE-TIME COSTS:
As part of the installation process, it will be necessary to establish connection with an Internet Service
Provider (ISP). The estimated cost of the initial ISP connection is estimated to be $395. Pacific Bell will
EXHIBIT 1

also charge an ISDN circuit installation fee estimated to be approximately $200. The workstations will
also need to have software used to access the websites. The AMS Consultant has suggested that the City
utilize a Microsoft Browser, which may be available at no cost. The website designer has suggested the
use of Netscape Navigator,. whi.ch ~ould need to be p~chased. The estimated cost of purchasing.' ':
Netscape for the 20 workstatIOns IS estimated to cost approXimately $700. :
The total estimated one-time communication installation/software costs for this alternative is
approximately $1,295.
The Grand Total of One-Time Costs (Equipment/Installation/Software)
$5,915
RECURRING COSTS:
ISDN is referred to as a "dial-up" circuit. This differs from a leased frame relay line (discussed under
Design B) in two major respects. First, the circuit is not always active, but must first be connected in
order to be active. Although the monthly circuit charge is relatively low ($28 per month), there is a
charge for each minute that the line is active. The amount of time that the circuit is active depends on the
hours that Internet Access is provided to Staff. Assuming the line is made accessible on average from
8:00 a.m. - 6:00 p.m. five days per week the cost would be approximately $160 per month. Leaving the
system active 24 hours per day during' the workweek would increase the line costs to approximately $340
per month. Staff assumes that this higher amount represents a service level which is not required.
Therefore, given that the cost of Pacific Bell Services would range between $160 and $340 per month,
Staff would suggest that a budget of $200 per month be used.
The City would also incur monthly costs for services provided by the Internet Service Provider (ISP).
The initial cost is estimated to be $395 per month, which would include access for 20 users along with E- .
Mail boxes. The ISP maintains the computer hardware actually used to access the Internet and would also :.
store the E-Mail until it is retrieved by Staff. ,...
The combination of the estimated Pacific Bell monthly costs of $200 and the ISP monthly costs of $395,
results in a total monthly cost of approximately $595 for 20 workstations.
The annual operating cost associated with the ISDN Option is estimated to be $7,140.
DESIGN B-1: FRAME RELAY CIRCillT AND REPLACE FILE SERVER:
This design utilizes a dedicated frame relay circuit. A frame relay circuit is a leased line which runs from
City offices directly to the Internet Service Provider (ISP). This technology differs from ISDN in the
sense that the line is a dedicated path which would run directly from the Civic Center to the ISP. The line
is always open and available as it is not being routed through other portions of the Pacific Bell Network.
A frame relay circuit is currently the fastest and most reliable method to connect to an ISP.
Unlike an ISDN circuit, the number of potential users is unlimited. Initially, a frame relay circuit would
enable all workstations to be configured to access the Internet. The system could handle all expected
traffic at acceptable performance levels. In the event that City expands its use of the Internet, the system
need to be modified, to utilize different Pacific Bell connections (high capacity data lines, such as
fractional T -lor full T -1). The type of connection obtained would not affect the basic equipment used
under this scenario. Only the monthly cost of a data line would increase the operating cost if circuits
faster than a frame relay were installed.
.
The equipment required for this alternative is much more expensive than the ISDN alternative. However, ."
the equipment would accommodate more activities in the future than are currently anticipated to be

utilized. In order to use a frame relay circuit design, the Consultant has indicated an additional server is
required. A server is a computer which allocates system resources to workstations. The cost of this
option is detailed in the following section.
Design B-1 Equipment Costs 1 Installation
If the City Council decides that a frame relay circuit is appropriate, the process described above would
result in the efficient use of existing equipment, however, there is a significant up-front cost which would
not be recouped for several years. The following is the cost breakdown for the Frame Relay - Design,
including a Replacement Network File Server:
Communications Equipment (CSU/DSU)
File Server - Equipment
InstallationIW orkstation Configuration
Sub-Total One-time Equipment/Installation
$ 15,960
11,000
8.000
$ 34,960
OTHER ONE-TIME COSTS:
As with the ISDN alternative there would still be a need to establish connection with an Internet Service
Provider (ISP). The estimated cost of the initial ISP connection is slightly higher for the frame relay
connection and is estimated to be $495. Pacific Bell will also charge a circuit installation fee estimated to
be approximately $1,005. Once again, this is a higher installation cost than the ISDN alternative. The
workstations will also need to have software used to access the websites. The AMS Consultant has
suggested that the City utilize a Microsoft Browser, which may be available at no cost. The website
designer has suggested the use of Netscape Navigator, which would need to be purchased. The estimated
cost of purchasing Netscape for the 52 workstations is estimated to cost approximately $1,820.
The total estimated one-time communication line installation/software costs for this alternative is
approximately $3,320.
The Grand Total of One-Time Costs (EquipmentlInstallation/Software)
$38.280
RECURRING COSTS:
Since a frame relay circuit is always open, there are no per minute charges, as with the ISDN alternative.
The only expense is the monthly line charge of $125. The Internet Service Provider (ISP) charges under
the Frame Relay alternative are estimated to be $425 per month. This is slightly higher than the ISDN
alternative, however, more users are being provided access.
The annual operating cost associated with the Frame Relay Option is estimated to be $6,600.
Potential Cost Saving If E-Mail 1 Internet Server Is Used To Also Host City Website
A potential advantage of Design B-1 is that the purchase of an Internet server would allow the City's
website to be hosted on a server at the Civic Center. As a result, there are no recurring costs for website
hosting and e-mail functions. Staff has not finalized the survey of Web site Host services, however, AMS
indicates that this could be a savings of$300 per month, or $3,600 per year.
The hosting of the website also complicates the ability of City Staff to support data processing operations
for the City. The addition of server and the hosting of a web site will increase equipment maintenance
expenses. Based upon prior experience, server malfunctions typically result in the need for 3 to 12 hours
of outside maintenance per year. This translates into increased maintenance expenses of $345 to $1,380
per year. This approach sacrifices the ability to rely on an outside computer service, which may have
redundant systems and better technical expertise to avoid system down time.

Exhibit 1
(page 3 of 4)
OPTIONAL INTERNET ENHANCEMENTS IDENTIFIED
AMS identified for the City's consideration the option to add additional security and/or controls to the
Frame Relay Option. These options are Hardware intensive and contain significant costs. Therefore they " :,
are not recommended by Staff, however, the informational descriptions provide background informatio.'
related to some of the limitations of the systems reviewed.
PROXY SERVER:
Cost: $11,080
This equipment would allow the network administrator to have complete control over internet access for
all computers on the local area network. All users would be required to first pass through the proxy server
prior to accessing the Internet. As a result, users could be effectively blocked from selected websites.
The server allows for a more restrictive use of the Internet. Typically, a proxy server is used in
environments, such as schools, to assure that objectionable websites are not accessed.
While there is some benefit to blocking access to objectionable web sites, such benefits do not justify the
high cost of a proxy server. Instead of the proxy server method, Staff will work with the Data Processing
User Group to develop policies and procedures related to acceptable use of the Internet.
FIREWALL:
Cost: $14,630
A firewall consists of software and equipment that creates a barrier to block unauthorized access from
outside users to the local area network. In secure environments, such as military installations or research
facilities, the high expense of sophisticated frrewalls is justified. You must also consider the nature of the
data residing on the network. This will become especially important when the City selects a replacement .~,
Financial System, which includes payroll, accounts payable, accounts receivable, etc.
All designs proposed by AMS include protections known as packet filters. These filters block access by
all but the most sophisticated users. AMS represents that it is theoretically possible, but extremely
unlikely (99.9%), that anyone would ever be able to "hack" into the City's local area network by breaking
the packet filter code. However, a frrewall creates an additional measure of protection, but at a very high
cost.
Staff has conferred with various City departments to assess these security concerns. Police Services
reports that no highly sensitive material is stored on the local area network. Other departments have
expressed only minimal concern. Staff believes that packet filtering is adequate protection for City
security needs and that a firewall is not required. In those case where data is extremely sensitive, internal
procedures, such as storing to floppy disks or tape, can be utilized to protect data.

City of Dublin
Internet and External Communications System
Executive Summary
The primary focus of the Internet and extemal communications project is to establish presence
for the City of Dublin on the World Wide Web providing a major benefit not only for the
community, but also for providing useful tools for key operations within the City departments.
This includes Internet mail, internal mail, and Web browsing.
As a result of several meetings between Robert Tocci and key City Departments, a list of goals
and priorities were established. Based on this list, we have designed two separate solutions to
provide both a lower-cost solution, with minimal services, as well as a higher-end solution
designed to meet current goals as well as provide scalability for future goals.
The first design is an ISDN dial on demand solution. The second design is a solution utilizing
Frame Relay technology for a dedicated circuit at 56K. We have also included several options for
increased perfonnance, scalability, flexibility, and additional features. Option 1 (Windows 95 and
Office 97 upgrades) and Option 5 (Fax Solution) can be implemented with either design. Options
2 (Proxy Server), 3 (PIX Firewall), and 4 (Senior Center and Heritage Center connectivity) require
Design B in order to implement.
For budgeting purposes, we have included the associated costs for implementation of each
project.
DesIgn A - ISDN Dial on Demand
The ISDN dial on demand solution was designed to provide a low cost solution providing minimal
services for the City. Each Department would be limited to selecting one user on the LAN to
have their desktop configured for intemal mail, Internet mail, and Web browsing. This user would
periodically throughout the workday, dial up the ISP to check for new mail forthe department,
send mail for the department, or browse the Internet.
Because this solution is dial on demand, a pennanent connection is not an option. Therefore the
City's Web page and mailboxes will have to be' hosted by the Service Provider.
Although this solution is less expensive, we feel it provides extreme limitations to the benefits of
World Wide Web presence, browsing and messaging systems.
DesIgn B - Frame Relay DedIcated Circuit
The dedicated circuit over Frame Relay provides all users on the Local Area Network with
Internet browsing as well as an integrated messaging system for both internal and Internet mail.
Because this circuit is dedicated at 56K to the City, you have constant connectivity. This
eliminates the need to "dial up" the Service Provider to check for new mail or browse the Internet.

This solution allows for the implementation of an integrated messaging system, which will provide
one mailbox for each user for both, intemal and Intemet mail.
Again, due to the dedicated circuit, the City can implement an Internet Server, which will allow for
their Web page to be hosted locally. Therefore, DNS will be operating locally. extremely
increasing the overall performance.
Although this higher-end solution will cost the City more initially, it provides extreme convenience,
scalability, functionality. and overall performance over the dial on demand solution.

ISDN Dial on Demand
.
ISDN Dial on Demand
Our design to provide the City with a low cost solution for limited Internet mail and browsing
access is an ISDN dial on demand solution. This solution would limit the City to select one user
per department to have the capabilities of Internet mail and browsing. The selected users would
be required to be on the City's Local Area Network to enable this access. ISDN connectivity
provides a maximum data rate of 128K.
The City's Web page would be hosted by an ISP (Internet Service Provider) who provides Web
page hosting as well as mail accounts. Because this solution is a dial on demand ISDN circuit,
users would be required to dial in to the ISP (Internet Service Provider) to retrieve mail and to
browse the Internet.
" ,
Internet ServIce ProvIder
AMS is recommending UUNET Technologies as the ISP for the City. UUNET will not only host
the City's Web page, they will also provide up to 20 POP mailboxes hosted on their mail server.
This will provide one mail account for each department associated with this project. The following
charges reflect the monthly costs the City can expect to pay UUNET for these services.

As with any project that dictates the way an entity runs certain aspects of their operations, it is
important to reflect both the pros and cons when determining a solution. The following highlights
both the benefits as well as the limitations the dial on demand solution provides. We have taken
into consideration not only the immediate needs the city is facing, but the long term as well.
Pros
· Less expensive - lower initial costs
· Increased performance, service, and maintenance over individual users
utilizing modems and individual mail accounts.
Cons
· Limited users - One per department
· Decreased performance over design B - No local DNS caching
· Inability to integrate local and Internet mail on desktops
· Inability to host Web site locally - Web documents must be saved using
an FTP program as oppose to the user friendly "save-as. function.
.:':.
.
Due to the dial on demand requirement, users may encounter busy
signals trying to connect to ISP.
· Users would be required to dial rsp to check. for new messages oppose
to receiving instant notification.
· Lack of scalability - Equipment purchased to implement design A can not
be utilized for future upgrades for higher bandwidth. Therefore, the
equipment, installation, and initial provider charges are forfeited.
· All mail accounts are to be created, modified, and managed by Service
Provider.
· Recurring cost - More expensive

City of Dublin Internet Project
Design B - Conceptual
56K Frame Relay Dedicated Circuit
56K Frame Relay DedIcated CIrcuIt
The implementation of a dedicated circuit over Frame Relay at 56K will provide all users on the
City's Local Area Network access to an integrated messaging system as well as Internet
browsing. In addition to providing capabilities for a Citywide messaging system, this dedicated
circuit also provides the foundation necessary for local Web page hosting through an Internet
server located in the MDF (Main Distribution Frame) of the City. Therefore, enabling the Domain
Name Services to be operating locally, extremely increasing the overall performance.
In this design, we have two options for implementing the Internet Server. Option 1 would provide
a more powerful server to run the City's file and print services. The existing server would then be
upgraded with additional disk space and RAM (Random Access Memory) to serve as the Internet
server. As part of option 2, the existing file and print server would remain as is and a Hewlett-
Packard NetServer E would be implemented as the Internet Server. Both options would provide
the power and performance necessary for such services. However, Option 1 would provide
higher quality, fault tolerance, and increased performance for file and print,,' services.
Furthermore. allowing the existing NetServer LM to be utilized as the Internet Server. Therefore,
increasing performance for both services.
Internet Service Provider
UUNET Technologies will provide the ISP services in this design. Please note the monthly
charges are based on a month to month basis. If the City chooses to sign a contract with
UUNET, monthly charges are subject to a discounted rate. The associated costs for their ISP
services are as follows:
. Start-up
· Monthly access fee
$495.00
425.00
Frame Relay CircuIt
Pacific Bell will provide the Frame Relay (56K) circuit to connect the City to UUNET. The
associated costs for their circuit access is as follows:
. Installation
. Monthly
$1,005.00
125.00

The following highlights both the benefits the 56K Frame Relay dedicated circuit solution
provides. We have taken into consideration not only the immediate needs the city is facing, but
the long term as well. .
Pros
. Unlimited users on LAN will have both mail and browsing services - Speed
however, is affected by quantity of users as well as traffic each user
generates
. Messaging system will integrate both local and Internet mail providing users
with one mailbox
. Local Web page hosting - greatly increasing ease of use for publishing
information on the Web
. Scalability - Upgrading to higher bandwidth (up to a T1) without having to
replace the routers. The CSUIDSU will need to be replaced with a TSU to
accommodate the connection to a faster circuit. The installation charges for
replacing the CSUIDSU for this upgrade are minimal.
. Provides a permanent connection eliminating any chance for busy signals
. Provides convenience and ease of use to users
. Lower maintenance
.
. Overall increased performance, usability, convenience, and features
. Lower recurring cost
Cons
. Increased cost - initial investment

REASON FOR BUDGET CHANGE ENTRY: The City Council requested that this project be advanced to allow for
use ofInternet communication links, and therefore funding was not included in the 1996/97 Fiscal Year Budget. Thi:
level of funding will provide for an ISDN internet connection and the configuration of 20 workstations. In addition <
shared modem device is proposed to provide an external gateway for communications not carried on the Internet. Th,
Budget change provides for 1 month of estimated operating costs for ISP and Pacific Bell Services.
