FXO & FXS Card

[lovefunlove]

Hello Guys ,

I have installed VIC-2FXS and VIC-2FXO Card on my Cisco 2651, but my router is not detecting the Voice cards.

I have seen the output of Show Version and Show Diag.

If i am installing any other WIC-2T it is detecting.

Can you Please let me know what might be the problem.

Waiting for your reply,

Regards,

MAX

Two possible cause might be:

*IOS is not voice capable.

*DSP resource are not available

But you had to realise even these are applicable while you were investigating "show ver" and "show diag" outputs.

So please check once more these two, and also if suitable send the outputs so we could help in detail.

Also, the WIC-2T just only prove slots are ok by the means of electricity, nothing else.

Thanx

2) Can you please let me know how to check the DSP Resource for my card.

First, let's examine the current system:

1-you have an 2651 XM

2-using an ios that is voice capable(c2600-ipvoice-mz.123-13)

3-the platform supports one network module and two interface cards

Secondly, let's examine what you did:

1-you installed a nm-4a/s (that means four synch/asynch serial wan interface) into the NM slot of 2651XM.

2-you installed a fxo and a fxs voice interface card into two built in interface card slots.

Lastly, see what is the problem:

1-nm-4a/s works without any problem

2-system does not recognise fxo or fxs cards

So let's see what is the reason:

1-2651xm does not support fxo or fxs interface cards into the built in interface card slots.(where you try to install fxo&fxs!!!)

2-2651xm supports voice interface cards by using a voice network module(instead you use nm-4a/s to get asynch/synch wan interfaces!!!)

At the end, let's say what must be the right hardware configuration:

1-one nm-hd-2v(to install into nm slot of 2651xm)(also this nm provide enough dsp for vics)

2-one vic2-2fxo and one vic2-2fxs(this cards must be installed into nm-hd-2v)

3-two wic-2a/s (this cards will be installed into built in interface card slots of 2651xm)

So you need:

one nm-hd-2v + one vic2-2fxo + one vic2-2fxs + two wic-2a/s; on the other hand, nm-4a/s will be unnecessary

Thanks
