COMSPHERE 6800 Series Network Management System
4-32 January 1997 6800-A2-GN22-30
One Local ACCULINK Multiplexer
For users with small networks, a single local 74x multiplexer may be sufficient. The event and
command ports are directly connected to the two NAPs. Multiplexer menu access is not essential;
nearly all of the functionality built into the multiplexer menu system is available through 6800
Series NMS commands. If users need to access the internal menu system of the multiplexer, they
can connect a terminal to a 74x NAP. Figure 4-19 shows the connections for one local
ACCULINK multiplexer.

Connection Procedures
This section explains how to make the various connections required to implement the four
configurations described above.
Connecting the 74x Multiplexer to the Host Processor
To connect a 74x multiplexer to the host processor, you must connect to one NAP on the 74x. A
NAP can be configured as either a Supervisory NAP or an Event Datagram NAP. The Supervisory
NAP connects to the external systems port on the host processor and the Event Datagram NAP
connects to the command and event ports.
The 6800 Series Network Management System Multiplexer Management and Configuration Guide
(6800-A2-GB48) explains how to configure multiplexer ports as either a supervisory NAP or
Event Datagram NAP. The following procedures explain how to connect each of these NAPs.
