WIC module questions

hiddenknight821

I'm a little clueless here. I just got the 2621 router in mail today, and it came with a ISDN BRI U module. I tried googling it up, but no one can explain it better than you guys. Do anyone have any idea what that is and what cable am I suppose to use to connect it to whatever I may need or is it not that important nowadays? I'm assuming it's obsolete and I can just ignore it.

It's pretty much useless unless you're also going to pick up an ISDN emulator or order ISDN service from a provider. ISDN was pulled off Cisco exams awhile ago
