isdn/pri spoofing

I have a GW which sows line up (spoofing) - we`re upgraded a Firewall and so now have this response- any ideas?- Is spoofing when the GW is bringing the circuit up so there are no alarms- what does it mean?

Re: isdn/pri spoofing

Spoofing is term used for historic reasons, that are too long to explain here.

Anyway it is normal to have that, if you want to further check your PRI, do show controllers T1 (or E1), and show isdn status.

Re: isdn/pri spoofing

Thanks for the reply, we only just seen it over the weekend. We`re done a Q931 debug and eveything is working fine with call I/C and O/G all ok From what I`ve seen it seems similar to a loopback diag commend on the D-channel to back bring up the line when there is not actual circuit which in our situation is not the case
