Same for E1 as well unless your operator is giving mfcr2 on cas.

Thank you Mitul for your answer.
Yes, we have tested e&m before and it works. But I don't know why. That is what I don't understand. You said that E&M signalling does not have separate signalling channel, that is true for the T1 but not for E1. My understanding is that E1 CAS pass the E&M information in the bits abcd of channel 16, the signalling channel.

We are trying to connect an Asterisk server with a Channel Bank with E&M interfaces using a RedFone TDMoE device.
The CB have a E1 CAS interface.

Error message:
========================================================
# dahdi_cfg -vvvvv
Changing signalling on channel 1 from Unused to E & M E1
Changing law on channel 1 from Mu-law to A-law
DAHDI_CHANCONFIG failed on channel 1: Invalid argument (22)
Selected signaling not supported
Possible causes:
e&me1 signaling is being used on a T1 line (use e&m)
RBS signaling is being used on a E1 CCS span
Signaling is being assigned to channel 16 of an E1 CAS span
=========================================================
I don't understand the last possible cause mentioned: "Signaling is being assigned to channel 16 of an E1 CAS span", because the dchan is channel 16.
Where is the error?
Thank you.
