be in the communications module (CM) complex. The parent PH will
periodically re-execute the QLPS loopback test and the GQPH QPipe
may be automatically recovered. Also, the SMP will schedule a full
restoral periodically.
An
OOS-LVL1-FRAME GQPH QPipe indicates that framing errors
have been detected at the NP channel. The nailed-up TSI-QPH path is
torn down and the NP channel is deactivated, and an undetected
failure is presumed to be in the CM complex. The parent SMP will
periodically attempt a complete restoral and the GQPH QPipe may be
automatically recovered.

It is possible that undetected faults in parent QTMSLNK/TMSLNK
hardware may be the reason that a GQPH QPipe is in the
OOS-QLPSLB or OOS-LVL1-FRAME state.
The first step in the analysis is to determine the state of parent
hardware to be recovered.
Access the QLPS Network status page:
138d
Where:
d = QLPS network associated with the target GQPH QPipe. Record
the QLPS in the target network.
If the mate QLPS in the target QLPS network is
OOS, which may be
due to parent ONTCCOM outage, then recover that QLPS. Refer to
the Corrective Maintenance procedure, Clear Quad Link Packet
Switch Problems, 235-105-220, to repair the QLPS.
If any QTMSLNKs are OOS, then refer to the Corrective
Maintenance procedure, Correct QTMSLNK Problems, 235-105-220,
to repair the identified QTMSLNKs.
