Installing the Carrier and Assembly Components
2-213000-A2-GA31-F0 March 2001
NMS Connection
A COMSPHERE 3000 Series Carrier can be connected
to a variety of Network Management Systems:
• 6800 Series NMS
• 6700 Series NMS
• DATAPHONE II Diagnostic Controller (DC)
The control channel CC IN interface, a 6-pin modular
jack on the SDU, connects the NMS to the carrier. Each
type of NMS requires a specific adapter to convert the
control channel interface to the 6-pin modular jack
required for the SDU.
This connection is via the control channel interface on
the SDU, but all 16 slots in the carrier can only be
controlled by one NMS. One control channel can manage
up to eight carriers by daisy chaining from the CC IN to
the CC OUT interfaces on the SDU in each carrier. Some
protocols result in DC OUT and DC IN. Refer to the
SDU CC/DC Operation section, page 2-18.
NOTE
You cannot use an NMS
connected through the SDU
with either T1 CSUs or
T1 DSU/CSUs.
Connecting the NMS
" Procedure
1. Obtain the correct adapter. Refer to Table 2-5,
page 2-22. Connect the adapter to the network
management port on the NMS device (on the
COMSPHERE and DATAPHONE II systems, the
port is labeled DC OUT or DC IN).
2. Use a 6-pin modular telephone cord to connect the
modular side of the adapter to the CC IN jack on
the rear of the SDU in the carrier. In the
accompanying illustration, 6-pin modular
telephone cords are shown as dashed lines.
3. After at least one device has been installed in the
carrier, check that the SDU is functioning properly
by polling the device for health and status.
4. For a cabinet configuration with multiple carriers,
connect all of the SDUs in a daisy chain, starting
with the SDU connected to the NMS.
— Use a 6-pin modular telephone cord to connect
the CC OUT jack at the rear of this SDU to
the CC IN jack of the SDU in the next carrier
above or below it.
— Use another cord to connect the second SDU’s
CC OUT jack to the next SDU’s CC IN.
Continue the connections until the last carrier in
the cabinet is connected.
