ISDN switch

Hi, all!

Is there any Cisco product that can configure

as teleco's ISDN switch? I cannot sleep well because of this question. Please help me!

Thanks.

All cisco ISDN interface support network as well user side configuration.

Hope this helps, please rate post if it does!

Thanks for your hint.

Important infomations slipped my mind.

I have some Cisco 2500 routers and

Cisco 4500 routers with multiple BRI module.

I want to let this 4500 relay at my home labo.

Does learning ISDN deeply make this come true?

Because Cisco's ISDN interfaces can send and receive q.921 and 9.31 signaling messages.

Honestly speaking, I couldn't understand

what you meant. But I see it now.

User side ISDN interface cannot pass

any signal to the opposite end of the

line, if it also is User side ISDN

interface.

I shed tonight till morning so that

the golden slumber doesn't come back

to me tonight.

Hi, for network side you will need the interfaces that are named nt/te. The routers you have are too old and don't have that.

Thanks for the appreciation and good luck!
