CUCM MGCP E1 Port Registration Status Rejected

Hello All,

I am currently running CUCM 8.6. Everything works properly until one of the gateway endpoint's registration status becomes Rejected. The other endpoints work fine (Refer to the attached screenshot).

show isdn status shows the following (I also attached screenshot of this):

ISDN Serial0/0/1:15 interface

    dsl 1, interface ISDN Switchtype = primary-net5

        L2 Protocol = Q.921 0x0000  L3 Protocol(s) = CCM MANAGER 0x0003

    Layer 1 Status:

        SHUTDOWN

    Layer 2 Status:

        TEI = 0, Ces = 1, SAPI = 0, State = TEI_ASSIGNED

    Layer 3 Status:

        0 Active Layer 3 Call(s)

    Active dsl 1 CCBs = 0

    The Free Channel Mask:  0x00000000

    Number of L2 Discards = 0, L2 Session ID = 28

It is my understanding that if Layer 1 Status shows DEACTIVATED, it means that the cable might be damaged. However, the status above shows SHUTDOWN. What does it mean?

show controllers e1 shows the following (I also attached screenshot of this):

E1 0/0/1 is down.

  Applique type is Channelized E1 - balanced

  Receiver has remote alarm.

  alarm-trigger is not set

  Version info FPGA Rev: 08121917, FPGA Type: PRK4

  Framing is NO-CRC4, Line Code is HDB3, Clock Source is Line.

  International Bit: 1, National Bits: 11111

  Data in current interval (481 seconds elapsed):

     0 Line Code Violations, 45 Path Code Violations

     0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins

     0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 481 Unavail Secs

  Total Data (last 24 hours)

     60004 Line Code Violations, 8436 Path Code Violations,

     181 Slip Secs, 2213 Fr Loss Secs, 35 Line Err Secs, 1 Degraded Mins,

     407 Errored Secs, 45 Bursty Err Secs, 0 Severely Err Secs, 68447 Unavail Secs

I am certain that the framing and line code are correct, as the CUCM has been working for months without error in the endpoints.

show voice port s0/0/1:15 shows the following:

DS0 Group 0/0/1:15 - 0/0/1:15

Type of VoicePort is XCC

Operation State is DOWN

Administrative State is UP

The Last Interface Down Failure Cause is Administrative Shutdown

I tried shut no shut no the voice port to no avail.

I also checked the equipment from the E1 provider, and it appears that nothing is wrong.

Please assist me in this issue. Any help will be appreciated

Hi!

To check your E1, you can use the command "loopback diag" after that you can issue "show controller E1" and check the controller status, of it comes up, that means that the device on the other end of the circuit is not configured correctly.
