Quick Set-Up Guide
This chapter is a step-by-step guide for installing the AS4000. For
the purpose of this chapter certain assumptions have been made
about module selections, circuit design and network architecture.
These almost certainly will not match your situation. Use this
chapter as a guide to the process of installing the AS4000, rather
than a literal set of instructions.
Complete details on hardware installation, system menus and the
various application modules are in the chapters which follow.
Example Network Scenario
The following assumptions are made about the example network
described in this chapter.
• The customer is an American firm, MegaBank Corporation.
They have large data centers in the San Francisco Bay area and
the greater New York City area. These two data centers are
connected with a T3 circuit. DS-3 Modules are used for this
link.
• At each of the data centers, a fractional T1 circuit is used to
connect Automatic Teller Machines (ATMs) running a polled,
synchronous protocol to a mainframe through a Front End
Processor. The local exchange company connects 32 remote
ATM locations, combining eight multipoint DDS circuits into
each of 4 timeslots in a fractional T1 to the data center. In this
way, sessions are simultaneously supported to 32 remote
ATMs at 56 Kbit/s each, using only 256 Kbit/s of T1
bandwidth. These four circuits connect via a Quad Sync Data
Port module to 4 FEP ports.
• At each data center TCP/IP routers connect the two local LAN
networks. These routers are connected to Quad Sync Port Data
Modules using a V.35 electrical interface.
• Voice PBXs at the MegaBank branches connect branch
employees to the data centers. The local carrier routes these
T1 circuits to each data center. Quad DS-1 modules are used
for these connections.
• Your task for this example configuration will be to install and
configure the equipment at the west coast data center, the site
shown on the right side in
Figure 2-1 .
