Voice gateway trunk problems

[anteboras]

I have 2 Cisco 2811 with 2 BRI ports each connected to Ericsson MD110 PBX. On that trunk I see data link errors on MD110 and CRC errors on Cisco BRI interfaces. Any suggestion for this problem?

Hello,

maybe you have to configure clocking. I only have an example for E1.

network-clock-participate wic 1

network-clock-select 1 E1 0/1/0

Try something like this?

What about the cable ?

ISDN uses 3 twisted with 6 und 4 twisted with 5.

Ethernet uses 1 twisted with 2 and 3 twisted with 4 and 5 wisted with 6 and 7 twisted with 8.
