NTP-012: Circuit Order 365-575-102
Page4of6 Issue8.0,July2002
12.
!
CAUTION:
If the purpose of this circuit pack is to
provide service for an OC-12c signal then
care must be exercised to complete all
twelve STS-1 cross-connections (in each
NE of the signals path) before applying the
OC-12c signal. Otherwise, the incoming
(from OC12) STS LOP alarm will be
produced.
At the CIT, select CONFIGURATION-Update
and execute.
NOTE:
If OC-12c signals are to be provisioned, all
high-speed transmitters and receivers in
the ring
must
be STS1-compatible.

13.
NOTE:
This step is optional. One of eight DCC channels can be assigned to
a slot (0x1 unprotected links only) that is equipped with an OC-12
circuit pack. The orientation of the OC-12 circuit packs is provisioned
"network" at one end and "user" at the other end. Both ends of the
OC-12 line cannot be the same and it makes no difference which end
is "network."
NOTE:
If you are establishing DCC connectivity for the first time, you may
have additional alarms, for example, multiple DSNEs defined
(TAP-139) and/or remote alarms. All alarms should clear after the
DCC stablizes; but if they do not, refer to the trouble clearing tab of
this manual.
At the CIT, select CONFIGURATION-Enter-
Assignment-DCC command to assign a DCC
channel to a single slot.
