Hi Group,
I am attempting to assist in the setup of a 4331, but am not very conversant with the 4000 series and have a few questions Im hoping someone will be able to answer.
I need to add a FXS port to a 4331 already containing a NIM-1MFT-T1/E1 and a, NIM-2FXO, to support a connection to a paging system.
Do I have room to install a 2-port FXS NIM?
I dont think I do without adding a SM-X adapter, is that correct?
If that is the case, and since the cost of a carrier plus the cost of an FXS card would exceed the cost of a 4fxo2fxs nim, it seems a better option just to replace the 2-port fxo.
Q2: I noticed when trying to find answers for the question above, this field notice on the 4000 series.:
which states that IOS XE versions earlier than 16.5 will not recognize the gen4 FXO/FXS cards.
I get the following information from a show ver:
Cisco IOS XE Software, Version 03.16.05.S - Extended Support Release
Cisco IOS Software, ISR Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 15.5(3)S5, RELEASE SOFTWARE (fc2)
The part that confuses me is that the IOS XE version (3.16.05) doesnt in any way resemble the minimum required version (16.5).
Since the router does recognize the 2-port fxo card I presume I dont need to worry about this issue. But can someone explain the apparent IOS version discrepancy?
Q3: If I change the 2-fxo to the 4fxo2fxs card, do I need a PVDM card to go with it? There seemed to be an indication that you dont with the Gen4 cards. There is a PVDM4-32 installed on the T1 card.
The router is at a remote site, making visualization and figuring all of this out somewhat more difficult.
I appreciate any help you can give in helping me wade through it.
thanks
