4000 determine D channel

[keyset6]

15+ years ago before leaving Siemens I worked only a few times with Direct Amo on the 4000. Asking on behalf of a former customer - how does one determine the D channel protocol of a PRI? I recall some commands were the same as the 9006. Maybe DIS-BCSU: TBL, then the PEN of the 24th channel? The customer has what appears to be a dual T1 card, DIU2U or something like that. So, the format of the PEN would need to indicate circuit 0 or 1 I believe.

To determine the protocol of an ISDN trunk you can display the trunk.

example:
DIS-TDCSU:1-1-1-0;

In there you would see 'PROTVAR' - indicating the protocol

Ok thanks. I guess BSSU or BCSU would be to display framing such as ESF B8ZS?

No BCSU only displays how the board was added.
What are the customer trying to do ?

For now just documentation. Thanks for the information.
