[Asterisk-Users] E100P configuration

[Musaluke AK]

Hello

I have been buttling to get a Valiant VCL-30 E1 channel bank multiplexer 
talking to asterik's E100P card.

The Spec for the VCL says this:

Coding: hdb3
Signalling: CAS
Timing: can be internal, external sync
Nominal Impedance: 120ohm balanced, 75ohm unbalanced
supports euroisdn

In the zaptel.conf file, I have:
span=1,1,0,cas,hdb3,crc4

The LED on the VCL indicates that I have a "Remote Frame Alarm"
The E100P also has an alarm on it.

Could anyone point me to something else I may need to configure to get this 
device working with *

Thank you

Anthony
