# PCM STATUS

## Qualifiers:

RX <link>

TX <link>

## Purpose:

Displays the status of any receive or transmit link or path.

## Details:

The command will cause all of the channels for the specified link to be printed.

PCM Status Command Printout Headings (see Example)
Heading | Description
Main Controller PLANE: | Identifies plane (A) and status (Active) of the plane on which the command was entered.
ACTIVE Processor: | ACTIVE node which is connected to this plane's Circuit Switch Matrix via the specified link. Location will be one of the following: DS1 Formatter CEPT Formatter
RX or TX Lk: | The receive or transmit link as specified on the command line (a number between 0 and 63).
RX or TX Ch: | The receive or transmit channel on the specified receive or transmit link (a number between 0 and 31).
Call State: | State of the specified channel, one of: Idle - not currently being used Assign - in use (speech or data path) Nonexist - no link (link is down).
ACTIVE, INACTIVE Maintenance State: | Maintenance state of the specified channel, one of: Idle - channel is 'healthy'. Suspect - suspected that a fault exists on the channel so that call processing cannot access it. Isolated - testing was done on the channel and the fault could be isolated to a particular card. If the card is replaced the fault should disappear. Unisolate - testing was done on the channel, but the fault could not be isolated to a specific card. PCM Camp - a Call Process is currently using the channel, but the PCM Path Integrity background diagnostic is camping on to the channel so that it can test it as soon as the Call Process is finished with it.
Owner Process: | The internal ID created upon process creation (a hex number between 0 000 and F FFF). Note that if the 'Call State' is IDLE, there will be no 'Owner Process'.
Owner Progname: | The program name of the process, one of: CPPROG - Call Processing LINETST - a line or trunk diagnostic process NOTE: If the 'Call State' is IDLE, there will be no 'Owner Progname'.
