I've been asked to check whether the Telco (BT) has set some ISDN lines as point-to-point or point-to-multipoint. If I plug a 2503 (or 2621 with a BRI S/T WIC) into them, is there part of a debug or show isdn command that would tell me? I know a tester would tell me, but someone's borrowed ours and is being somewhat coy about its whereabouts. Thanks in advance.
