I also tested to loop on the other equipment, and it seems to work. So
the problem only appears when the TE410P tries to speak to the other
equipment.

On the latter, I can choose the linetype to be one of the following:

E1Unframed           - 2 Mbit/sec unframed signal
E1                   - 2 Mbit/sec framed PCM31 signal
E1Crc                - 2 Mbit/sec framed PCM31 signal with CRC
E1Mf                 - 2 Mbit/sec framed PCM30 multiframed signal
E1CrcMf              - 2 Mbit/sec framed PCM30 multiframed signal with
CRC

Since I want to use PRI signaling I have configured zaptel in CCS mode.
So I think the right choice on the other equipment would be "E1", am I
right? Or is it "E1Mf"?

Thanks,
Johan.
