0563 - IMT Bit rate mismatch detected

This message indicates that the the IMT Bus A and B are operating at different bit rates. This can occur if the BERT Test fails for only one bus, or if some of the HIPR2 cards have been replaced with HMUX/HIPR cards after the HIPR2 High Rate Mode feature was turned ON.

Note:

This UAM might appear during transition phase when the HIPR2 High Rate Mode feature status has changed, but eventually it will be cleared if high bit rate is established on both IMT buses.

Alarm Level: Major

Recovery

1. Verify the card status. Enter this command: rept-stat-mux.
   Example of the output:

       CARD   TYPE       PST            SST        AST       BITRATE   BITRATE
                                                              (OPER)    (ACT)
       ------------------------------------------------------------------------
       1109   HIPR2      IS-ANR         Restrict   -----     HIGH      LOW
       1110   HIPR2      IS-NR          Active     -----     HIGH      HIGH
       1209   HIPR2      IS-ANR         Restrict   -----     HIGH      LOW
       1210   HIPR2      IS-NR          Active     -----     HIGH      HIGH
       1309   HIPR2      IS-ANR         Restrict   -----     HIGH      LOW
       1310   HIPR2      IS-NR          Active     -----     HIGH      HIGH
       Command Completed.
   

2. Enter the command to verify the IMT status: rept-stat-imt.
   Example of the output:

   
        IMT   PST              SST          AST
         A    IS-ANR          Restrict     -----
         ALARM STATUS       = No alarms
   
        IMT   PST             SST         AST
        B     IS-NR           Active      -----
        ALARM STATUS       = No alarms
   
       Command Completed.
   

3. Replace the faulty HIPR2 card or replace the HMUX/HIPR cards with HIPR2 cards.
