Nuera info

Hi, I need to get rid of a Nuera box (a kind of FP-2000 or something) that is attached via E1 link to a PBX.
The problem is that the telnet CLI interface of Nuera is like a voodoo. I need just to get some settings from the box:

1. setting of the link to the PBX – type of signalling, framing, who is providing clocking.

2. codec

3. voice peering configuration (destination IP, type of signalling – RRQ, LRQ, GW-GW)
