I tried tonight to get a QSIG link from a spare port on my CMM (CUCM6.1 controlled) to connect to our Aspect switch.
Despite trying various settings at both ends, i never saw the CMM go beyond "Layer 1 DEACTIVATYED" when i issued 'sh isdn status' command.
This would suggest that my CMM port never got a proper layer 1 (basic) connection from the Aspect, thus layer 1 never came up.
Ive used a straight-thru cable (cat6) to connect the CMM to the Aspect card.
Im wondering if this should have been crossed, maybe at the Aspect end??
How are most E1 connections done cable-wise? Should it be crossed in some way?
Any help appreciated. A little stuck at the moment :)
Oh - we use MGCP. I set my end in CUCM to be 'user' because the Aspect was set as 'master'. Tried turing CRC4 on and off, and a few other settings - never saw layer 1 come up tho, so i think ive made a basic error somewhere :o)
