PA-POS-2OC3 vs NM-1A-OC3SMI

[ahmad82pkn]

Hi Team, i have Cisco 7200 VXR in which OC3 circuit is terminated.

Module installed in VXR is PA-POS-2OC3

Now i have to move this connection to 3745 Router.

What i need to know which card is required to connect OC3 in cisco 3745, as per online search this module NM-1A-OC3SMI will work, but i am confused with term ATM OC3 module, so is this the right card to connect same OC3 circit on 3745?

Thank you

its a hardware constraint for slot population.

Hi Miller, Thank you for biringing this in my knowledge, i didnt know it earlier.

so NPE-400 has 600 Bandwidth point on each left and right bus.

If i buy below Fast Module and install on left side.

2-port Fast Ethernet/Ethernet I/O controller

C7200-I/O-2FE/E8

High

400

and buy below OC3 module on right side, then i am good to go? as i didnt exceed 600Points on any interface

1-port SFP module-based OC-3c/STM-1

PA-POS-1OC3

High

300

Please correct me if i understood it right?

My requirement is to connect OC3 interface ( max traffic expected 80Mbps +- ) and connect this router to my LAN.

you should be ok. I would go with the NPG-G2 also.

I'm not 100% sure but the NPE-400 might be EOS.

I wish i was given enough budget to go for NPE-G2 :-s

At this time, i have to get something cheap.

after searching online from different vendors websites. to ful fill my 80Mbps traffic requirement over OC3.

here is what i will finally get.

Lets hope i dont run into any serious issues

300$-PA-POS-OC3SMI /Duplex SC-Type Cable and Connector

100$-C7200-I/O-2FE/E

300$-NPE-400  

300$-CISCO7204VXR

100$-64MB ATA PCMCIA card 7200VXR compatible

1100$ Total

By the way is there any other Cisco dedicated forum, that help buying/selecting equipment, like pre sale forums?

Both the 3745 and 3845, especially the 3745, are a bit lightweight even for 100 Mbps.  If you look at the performance sheet Paolo provided as a reference, look for a router that does at least 2x the Fast/CEF switching Mbps you expect to utilize to allow for duplex traffic.  3 to 4x is even better as you really don't want to push a software router routinely pass about 70% utilization.

If you go with a Ethernet hand-off route, L3 switches also become an option (depending on your feature needs).
