COMSPHERE 6800 Series Nework Management System
Once you have completed configuring the necessary ports, refer to Chapter 1 to connect to the
NMS.

Configuring 74x Multiplexers

Each 731/74x or 74x-56K multiplexer has two network administration ports (NAPs), which are
special communication ports (EIA RS-232) that relay 6800 Series NMS commands, multiplexer
tests, test results, and event/alarm information between the NMS host computer and the various
multiplexers within the network. In addition, a NAP can be configured as a supervisory data link
(SDL) for communicating with a 719 NETWORKER, and for passing external diagnostics to a
data channel, or as an event log printer for printing network events locally.
The NAPs are configured by selecting options from the internal multiplexer menus. To access
these internal menus, you must temporarily connect either a terminal or a PC to the multiplexer.

Connecting a Terminal or PC to the Multiplexer

For the configuration process, you can use either an asynchronous ASCII terminal or a PC. If you
use a PC, a VT-100 terminal emulation program must be installed and running before you can
configure the multiplexer.
When the configuration procedures are completed, the terminal or PC may be disconnected from
the multiplexer. At that point, the PC may also be used as a basic-feature workstation on the NMS.

Connecting an ASCII Terminal

Any ASCII terminal can be used to configure the multiplexers. Make sure the following
parameters are set on the terminal:
You need an EIA RS-232 (DB-25) cable to connect the terminal to the multiplexer(s).
