Configuration
DEFINITY Extender Model 3000 is a central site device
installed at the DEFINITY ECS location. It is mounted to a
chassis in the equipment room and powered by an internal
120V power supply. The Rack accommodates up to 12
Switch Cards allowing 12 remote users (using Model 3100
Switch Cards) access to the system.
The Rack requires Switch Cards to be installed to provide
voice and data connectivity using standard telephone lines.
All connections, internal and external, are wired through
the Rack backplane. The DEFINITY ECS and Public
Switched Telephone Network (PSTN) connections are
wired using four 50-pin connectors installed on the
backplane.
The data connection acts as a simple null modem cable
extending the corporate data network to the remote
location. The backplane provides two data ports (COMA,
COMB) per Switch Card, allowing connection to the
corporate Remote Access Server or Terminal Server.
Example: The COM ports for the Switch Card in Rack slot
0 are labeled as follows:
COM0A
COM0B (only used with Model 3200
Switch Cards)
The administrator can configure, troubleshoot and update
every Switch Card in the Rack from a single ADMIN port,
using a Windows based management software package.
See the Switch Management Interface section on page 1-7
for more information
Note: Switch cards can also be configured individually by
attaching a VT100 compatible terminal to COMA of each
Switch Card.
