Cisco EVM-HD

Good day, we have a Cisco High-Density Analog And Digital Extension Module for Voice and Fax (EVM-HD)for our new Cisco 3845 Router. My question is, what did you call about the port connection at the back of the Module, its like a female serial connection 25 pins. Is it shipped with a cable to be connect on that module? I will wait for your answer, thanks.

It is called a 50 pin RJ 21 connector. The cable is not shipped with module - check table 5 at

Hi Mahmoud,

Just to add a note to Mauliks good info (5 points for this nice work Maulik!)

Connecting Cisco High-Density Extension Modules to the Network - ***Make sure you order the RJ21 with a "MALE" connector***

The Cisco high-density extension module is connected to a distribution frame or patch panel with an RJ-21 cable.** RJ-21 cables are not provided with the network module.

Here are the parts you would need to connect to a 24 port rack mounted Patch Panel (without needing to terminate the cable with Bix or 110 connecting tools).

24 Port with RJ21 Male

These are just examples :) I have not checked pricing $$

Hope this helps!
