Identifying type of ISDN BRI Interface

How can I identify what type of ISDN BRI interface (S/T or U) on my router?

For example there's no label on 2503 chassis about BRI intf type?

Regards.

Re: Identifying type of ISDN BRI Interface

Hi,

For my 2500 running 11.1(14) same command output is:

router#sh controllers bri 0

BRI unit 0

D Chan Info:

Layer 1 is ACTIVATED

idb 0x94A60, ds 0xA3118, reset_mask 0x8

buffer size 1524

RX ring with 2 entries at 0x2101600 : Rxhead 1

I think it's about IOS version.

Regards.
