As I see - 1-4 is supporting, but have doubt about 5 and 6.

Thank you!

Alexandr,

Number 5 is supported. We support framed or unframed E1. For framed E1 we support basic and multi frame both with CRC-4.

For number 6 our signaling option for a framed E1 is bit-oriented (CAS). I believe CCS would be transparent to the switch so we would pass the data but not act on it.
