We are trying to setup an ISDN BRI connection from a video endpoint to a 3845 gateway as described in this document....
All is configured ok, can see all ports but have no layer 1 connectivity on the BRI ports.
ISDN BRI2/0 interface
******* Network side configuration *******
dsl 16, interface ISDN Switchtype = basic-net3
Layer 1 Status:
Layer 2 Status:
Layer 2 NOT Activated
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 16 CCBs = 0
The Free Channel Mask: 0x80000003
Cisco IOS Software, 3800 Software (C3845-IPVOICE_IVS-M), Version 12.4(3g), RELEASE SOFTWARE (fc2)
We are using a straight through patch cable from the Tandberg endpoint to the blackbox distribution frame. Do we need a special cable?
