(continued) CMS In/Out Port Automatic Setup
Figure 12-3 on page 12-27 is a block diagram showing the CMS In/Out Port test
configuration for a TLM circuit pack within an Optical line under test. Upon
completion of the Supervisory Channel Test, the Optical Line fibers from transmit
OA (out)-to-OA (in) are opened, and the CMS fibers (and optional attenuators)
looped. After issuing the CONFIGURATION.Update command at the CMC, the
board controller for each TLM pack of the Optical Line(s) under test will
automatically:
■
Switch TLM pack synchronization source to the internal 51.84-MHz
Stratum 3 Clock Generator
■
Have the C-STS13BP device insert PATH AIS signal in the Out direction of
the CMS In/Out Port.
CMS In/Out Port Continuity Test Operation
Once setup and initialization are complete, the following operations are performed
to confirm CMS In/Out Port continuity per TLM slot:
(Continued on next page)
Step Action
1 Verify no C1 parity error is detected at the C-STS13BP device of the TLM
pack by enabling parity error insertion via TEQPAREN function, sending
good parity via TEQPARTST function, and reading REQPARER.
2 Insert C1 parity error at the C-STS13BP device of the TLM pack via
TEQPARTST function.
3 Verify C1 parity error is detected at the C-STS13BP by reading
REQPARER.
4 Remove C1 parity error at the C-STS13BP via TEQPARTST function.
5 Verify no C1 parity error detected at the C-STS13BP by reading
REQPARER.
