Connecting to the Network
The DSU provides three interfaces. One jack connects the DSU to the 6700 or 6800
Series NMS, one connects the DSU to the dial (or public switched telephone network –
PSTN) network, and one connects the DSU to the DDS network. Follow the appropriate
procedure when making your network connections.
Connecting to the NMS
A 3600 Hubbing Device is required to connect the control DSU to the 6700 or 6800
Series NMS. When connected to the NMS, the DSU can be controlled and configured
from the NMS rather than from the DCP alone.
Procedure
1. Plug the 4-pin modular plug of the 3600 Hubbing Device into the DSU jack labeled
CC/DC.
2. Plug one end of an M6BJ cable into the hubbing device jack labeled CC IN/DC
OUT.
3. Plug the other end of the 6-pin M6BJ cable into the 6-pin end of the 873A adapter.
4. Plug the D-type end of the 873A adapter into the appropriate 6700 or 6800 Series
NMS jack.
Refer to your COMSPHERE 6700 or 6800 Series NMS documentation to control and
configure the DSU from the NMS.
