    Hello!

    Can somebody help with compliance with the requirements?

    Is E4G ports E1 support next:
    1 - 120 Ohm resistance
    2 - ITU-T Rec G.703, G.704, G.706, G.732, G.823
    3 - Speed - 2048 Mbps
    4 - Coding HDB3, AMI
    5 - Support E1 framed/unframed, with or without CRC-4
    6 - Signaling CAS, CCS (transparent)

    Thank you!

    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.
