Hi All,

We have configured the E1 interface in the router & that is connected with PBX

We observed that lot of channels locked out issue in the PBX side. Same time in the Q921 status we got both Multiframe established & Tei Assigned

How we proceed further to troublshoot ?

ISDN Serial1/0/1:15 interface

        ******* Network side configuration *******

        dsl 3, interface ISDN Switchtype = primary-net5

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

        ACTIVE

    Layer 2 Status:

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

        TEI = 32, Ces = 255, SAPI = 44, State = TEI_ASSIGNED

        TEI = 1, Ces = 255, SAPI = 32, State = TEI_ASSIGNED

        TEI = 0, Ces = 1, SAPI = 32, State = TEI_ASSIGNED

        TEI = 16, Ces = 255, SAPI = 28, State = TEI_ASSIGNED

    Layer 3 Status:
