Solved: connecting 2851 routers' E1 ports back-to-back

alfonzofernando · ‎02-11-2007

I have two 2851 routers with VWIC2-2MFT-T1/E1 cards. before deploying them on field,I want to simulate E1 links at the lab. there are regular rj45 ports on E1 cards.

Can I connect routers back-to-back using E1 modules (if ethernet cable would do the job,how should I terminate pins on RJ 45 connectors?)

tx in advance for any help

Hi,

yes, you can.

You just need E1 crossover cable.

Hi,

You need an E1 cross cable which you need to manually crimp.

Router 1 Router 2

Pin 1 connects to Pin 4

Pin 2 connects to Pin 5

Pin 4 connects to Pin 1

Pin 5 connects to Pin 2
