PRI Endpoint Port Service States
The following table summarizes each of the different PRI Endpoint Port service
states that can result when the status pri-endpoint <extension> command is
issued. From the results of the status command, match the service state to the
corresponding column. Proceed down the column until an "X" is found. The left
column indicates possible reasons why the port is in this state, and the right
column suggests possible recovery mechanisms. If an alarm against PE-BCHL is
present, it is indicated below the "X."
