The 2503 and 2522 are S/T. Usually on U interfaces,
the interface has 'ISDN U' or similar. Most of the
older routers are S/T but some may be U. It is
sometimes hard to find if something is S/T or U in
some cisco docs. Older docs say the port is ISDN BRI
only. On newer docs I've read they mention the
interface type. What I do sometimes is go to
google.com and search on cisco 2503, etc and look at
other companys selling it and some of those have the
ISDN interface type in the description/specs.
You can do the following to find out also:
router#show int bri0 (cisco 800)
BRI0 is up (spoofing), line protocol is up (spoofing)
Hardware is BRI with U interface and POTS
Router#show int bri1/0 (cisco 2620)
BRI1/0 is administratively down, line protocol is down
Hardware is BRI
router#show diag (2620)
Slot 1:
BRI (S/T) Port adapter, 4 ports
