Procedure 14.3: ACTIVATE GDSF LOOPBACK LTP SERVICE
OVERVIEW
CAUTION:
This procedure cannot be performed unless preconditioning Procedure
14.2
has been performed first.
The GDSF (global digital services function) loopback LTP (logical test port) service requires first growing a trunk
group (if required) and then the trunk members. Once these are grown and verified then the standard route index
and the fixed route index are defined.
Growing the loopback service requires the use of the MCC (master control center) terminal and the RC/V (recent
change and verify) terminal for updating the data bases and verifying the activity. It must be determined if a trunk
group already exists for the GDSF loopback service, if not, then the trunk group must be grown.
It is necessary to obtain all the data required to build the loopback service before beginning the process. Refer to
Translation Guide TG-5, office records, and GRCV (growth recent change and verify) forms as required.
Safe Stop Points
are provided where progress in the execution of a procedure may be suspended temporarily
without causing degradation in the operation of the equipment. Execution of the procedure can be halted at one of
these points only if all prior steps within the procedure have been successfully completed. Should this procedure not
be completed and required to be carried over to the next day, then a backup of the office dependent data (ODD),
(Procedure
14.3.15
, Step 4) should be made to prevent losing recent change activity.
