Max # of Point-to-Point T1's a 3845 can handle?

Unanswered Question

We currently have a 3825 that has 4 VWIC2-2MFT-T1/E1 2-Port T1/E1 Voice / WAN w/ Drop & Insert modules in the built in wic slots.

This currently gives us 8 T1 connections. I need to move up to atleast 16 T1 connections (point to point) so we are going to move to a 3845 model.

The only T1 based network modules I could find were NM-HDV2 modules.

These seem to have a slot for 1 2 port t1 module and also 2 built in t1 ports.

What confuses me is that this NM only talks about voice on its reference page:

http://www.cisco.com/en/US/partner/tech/tk652/tk653/technologies_tech_note09186a008039c333.shtml

Is this the correct NM to purchase? And assuming we fill the 3845 up with those NM's all with dual port t1 modules, whats the max I can see as far as t1 connections?

Thanks!

I have this problem too.

Hi,

the correct module would be nm-2w, basically just an holder for the vwic and nothings else.

However with such a T1 density your best choice would a 7200 with two PA-8E1/T1 and job done without too many parts.

Hope this helps, please rate post if it does!

Check the leading auction site. Works for me every time I have to design on a budget. You don't need any latest NPE for the 7200, a 300 will do.

Thanks for the rating and good luck!
