Procedure 11.32: DEGROW DNU-S STE/STS-1 FACILITY - 5E10(1) AND LATER
OVERVIEW
This procedure degrows Digital Networking Unit - SONET (DNU-S) SONET Termination Equipment (STE) and
Synchronous Transport Signal (STS-1) facilities.
Two separate degrowth procedures exist for degrowing the DNU-S Virtual Tributary 1.5/Digital Signal 1 (VT1.5/DS1)
facilities.
For 5E12(1) and earlier
Procedure 11.30
For 5E13(1) and later
Procedure 11.54
This procedure requires that the associated VT1.5/DS1 facilities be previously degrown.
Safe Stop Points are provided in the procedure set where progress in the performance of a procedure may be
suspended temporarily without causing degradation in the operation of the equipment. Performance of the
procedure can be halted at one of these points only if all prior steps within the procedure have been successfully
completed.
PROCEDURE
1.
Degrow DNU-S STE/STS-1 Facility - 5E10(1) and Later
11.32.1 Verify and Set Initial Conditions
1.
At the Master Control Center (MCC), observe Summary Status Area for a SYS NORM indication.
2.
If a SYS NORM indication is not obtained, type and enter the following command:
OP:SYSSTAT
3.
At the MCC, type and enter the following command:
OP:OFFNORM,SM=
a
Where:
a = Switching Module-2000 (SM-2000) number.
4.
Evaluate system response to determine if system status is acceptable to continue. Specific attention is
required for areas that can cause SM-2000 isolation or service impact during this STE/STS-1 Facility
degrowth procedure. Correct any deficiency as required.
NOTE:
Steps 5 and 6 are recommended but not required. Local practices should control their use. If REX is
inhibited, it must be allowed at the conclusion of this growth procedure.
5.
At the MCC, type and enter the following command:
602
(1800,a CMD)
or
INH:REX,SM =
a
