Task 7: Install the Terminals
Issue 2 December 1996
2-13
Reserved RS-232 Connection
Do not connect the RS-232 connector on the ALB cable In the U.S. The standard
alarm origination circuit uses an on-board DEFINITY AUDIX system modem that
is internally wired to the amphenol connector on the ALB cable. The RS-232
connector on the cable is used in installations outside of the U.S.
MFB Port Usage for DS and CL Integration
The Multifunction Board (MFB) Y-cable has two RS-232C connectors labeled Port
A and Port B.
When using DS integration, both the Port A and Port B connectors can be used
for either administration or maintenance and both can be connected to a
system-access terminal either locally (directly) or remotely. The primary
system-access terminal should be connected to Port A. The only difference
between Port A and Port B is that some system diagnostic messages, created
only when the system is booting, are sent to Port A but not to Port B. These
additional messages are not useful during normal operation of the system.
When using CL integration, Port B is used for the connection to the switch and is
not available for a system-access terminal. In this case, only one terminal is used
and it is connected to Port A. This terminal is usually connected locally but can
be connected remotely, if desired. Should ADAP software be used with this
terminal, the terminal must be connected to Port A via a modem connection
(See Task 7B: Install a Terminal via Modems).
Perform one of the four Subtasks, 7A, 7B, 7C, or 7D — (depending on the
connection type) to connect a system-access terminal to Port A, and, if desired
and when using DS integration, to connect a second terminal to Port B. Use
Worksheet E-1,
Terminals , to determine which tasks to complete.
The descriptions of Tasks 7B, 7C, and 7D assume that you are connecting a
remote terminal to Port B. You can also use these tasks for a remote connection
to Port A by substituting
A for B in the descriptions.
Proceed to Task 7: Install the Terminals.
Task 7: Install the Terminals
This task is required for all installation scenarios.
You will install one or two system-access terminals used to perform
administration and maintenance operations. One system-access terminal
connected to Port A is required. This terminal is usually connected via a direct
cable connection to Port A but can be connected remotely if desired. If the
DEFINITY AUDIX system is being installed to use DS integration, a second,
optional terminal can be connected to Port B.
