Is the E1 card an isdn card or something else? There are a several
signalling systems that can run over an E1.

When running cas you do not have a D channel for the signalling. Instead 
each voice channel has a few dedicated bits in channel 16 (hence Channel 
Associated Signalling). This is used for E&M, loopstart etc and is 
incompatible with the ISDN signalling that you tried.
