Hi Guys,

I just ran a sh isdn status command on voice gateway & found that layer 2 status is looking weird, Is there anyone who knows, why is that ?

Here is the output:

cpp-vgw-1#sh isdn st

Global ISDN Switchtype = primary-4ess

%Q.931 is backhauled to CCM MANAGER 0x0003 on DSL 0. Layer 3 output may not apply

ISDN Serial1/0:15 interface

        dsl 0, interface ISDN Switchtype = primary-net5

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

    Layer 1 Status:

        ACTIVE

    Layer 2 Status:

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

        TEI = 0, Ces = 1, SAPI = 63, State = TEI_ASSIGNED

    Layer 3 Status:

        0 Active La

    Active dsl 0 CCBs = 0
