         **** Slave side configuration ****

    Layer 1 Status:

        DEACTIVATED

Layer 2 Status:

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

    Layer 3 Status:

        0 Active Layer 3 Call(s)

#sh controller E1

E1 2/0 is up.

  Applique type is Channelized E1 - balanced

Hi,

Can u try changing the CRC-4 to framing no-crc-4?

If possible, try changing from H.323 to MGCP?please refer the DOC.

Hi Aman,

Thanks for helping, yes i tried changing from CRC4 - no CRC4, however no luck.

I cannot change from H.323 to MGCP, there is no Cisco call manager. and router is in production can do that now.

Well "Serial2/0:15 is down, line protocol is down" indicates that there's not even the Layer 1 working. So are you really sure the cables are working properly?

Do you have a loopback cable to test the interface card, so we're sure the card is working properly?

If there'd been CRC4 errors the E1 2/0 would be down too.

Thanks Marc,

Yes i did the loopback cable test to on the interface card, here is the logs i took from voice gateway.

You need to configure ISDN network side, thing for which you can search about.
