TDM hairpin

I have a loop back on a ds3 port and want my calls to hairpin across 2 ds1s. Calls would go out of say (T1 1 and comeback on T1 2)Is it supported on 5400? If yes, could you please point to relevant config either for ISDN or FGD.

Thanks in advance!!

Re: TDM hairpin

Yes, it is completely possible. Indeed, this could be called "TDM switching" rather than hairpinning. Hair pinning is when you switch between the timeslots of the same T1/E1.

Just configure two pots dial-peers and that is.
