Network Diagnostic
Connection
A 3600 Hubbing Device (feature number
3600-F3-300) is required to connect the control DSU to
the 6700 or 6800 Series NMS. The hubbing device plugs
into a modular jack located on the rear of the DSU and
provides two 8-pin modular jacks for diagnostic channel
(DC) and control channel (CC) connections.
NOTE
When installing 3600 Series
DSUs and 3400 Series or
DATAPHONE II modems on the
same diagnostic channel, install
the DSU ahead (upstream) of the
modems. This configuration
prevents the DSU from losing
contact if the modem loses power.
If using extended diagnostics, when making
DC OUT-to-DC OUT connections between the tributary
and the extended control DSUs, an 871A 6-pin turnover
adapter is required (feature number 4400-F1-594, labeled
002-0025-0031).
"
Procedure
1. Configure the DSU for either CC or DC operation
(refer to the
Diag Conn
section of Diagnostic
General Configuration Options, Table 6-4).
2. Plug the 4-pin modular plug of the 3600 Hubbing
Device (Figure 2-4) into the DSU jack labeled
CC/DC.
3. Plug one end of an M6BJ cable into the hubbing
device jack labeled CC IN/DC OUT.
4. Plug the other end of the 6-pin M6BJ cable into
the 6-pin end of the 873A adapter.
5. Plug the D-type end of the 873A adapter into the
appropriate 6700 or 6800 Series NMS jack.
Refer to tables in
Chapter 6
for examples of diagnostic
configuration options. Refer to your COMSPHERE 6700
or 6800 Series NMS documentation to control and
configure the DSU from the NMS.
