alarms and performance events, provides maintenance features, and
supports the TPS protection.
Table 1 provides the functions and features of the PQM.
Table 1 Functions and features of the PQM
Function and Feature
PQM
Basic functions
Processes 63xE1/T1 signals.
Service processing
Transmits/Receives and processes 63xE1/T1 electrical signals when
working with the interface board. Each channel can be configured as
E1 or T1.
Overhead processing
Supports the processing of the path overheads at the VC-12 level,
such as the J2 byte.
Alarms and performance events
Reports various alarms and performance events, which facilitates
the management and maintenance of the equipment.
Maintenance features
Supports inloops and outloops at electrical interfaces.
Supports warm resets and cold resets. The warm reset does not
affect services.
Supports the query of the manufacturing information of the board.
Supports the in-service loading of the FPGA.
Supports the upgrade of the board software without affecting
services.
Supports the PRBS function. For details, see Availability.
Supports the CRC function.
Protection schemes
Supports the TPS protection when working with the interface board.
When the working board is the N1PQ1, the protection board can be
the N1PQ1, N2PQ1 or N1PQM. In this case, the hybrid protection is
provided.
When the working board is the N1PQM, the protection board can only
be the N1PQM.
