Router Cisco 3745. Connecting E1s.

[jamores]

Hi,

I have a router cisco 3745 without networks modules.

I need to connect to this router a lot of E1 (structured or not structured) and I need to know what is the best option in order to connect those E1 to the router.

I am wondering if "NM-8A/S" is a good choice (in order to connect the E1 directly to the router without a utr).

I have been searching the documentation but I don't get enough information.

¿Is it possible to connect E1 directly to the NM-8A/S card?

Thank in advance for your help.

Regards.

Hi

E1 is of 2048Kbps which is not supported by any of the A/S cards.

They can only support a max of 128Kbps and also can support 64Kbps.

if you need to have 2Mbps speed then you need to check out for NM-4T cards or if its ok for u with 128/64 u can check out for A/S cards.

do check the support matrix avl for 3745 chasis..

Hi,

Thanks a lof for your help.

My problem is that, just due to the great quantity of E1 that I must connect to the router, I need cards with which I don't need utr (CSU/DSU).

I have been reading about NM-2CE1T1-PRI card (in order to connect four this cards to my 3745).

My question now is if I can connet directly (without utr (CSU/DSU)) an E1 to the RJ45 connectors of the NM-2CE1T1-PRI card? (I suppose the answer is yes but I would like to be sure before buy those cards).

Thanks a lot again.

Regards.

Hi

Yes the cards will have inbuilt CSU/DSU so no need for external one.

just plugin the RJ 45 taken out from ur DDF or MDF onto the router..
