PCM30 line drawer maintenance description

The existing standard line drawer (SLD) maintenance has been extended to
support the maintenance of the PCM30 line drawer (PLD), specifically the
PCM30 interface card (PIC), which is an integral part of the PLD.
Maintenance is performed by the line concentrating module (LCM) drawer
maintenance, which is part of the LCM maintenance, and includes
maintenance of the PIC. Therefore, the automatic and manual maintenance
procedures executed on the PLD are similar to those executed on the SLD.
The codes that indicate the state of the PLD are similar to the codes for the
SLD. The codes are listed below with a brief description. The state of a
drawer is changed either automatically by the system, or manually by
inputting commands at the MAP terminal. Log report PM181 is generated to
indicate the state changes, for example, ManB from SysB.
