Hello,
I am currently looking for a Cisco terminal server solution to remotely access through console my private Cisco home lab. I am thinking of buying Cisco 2811 but I struggle to figure out the difference which ASYNC/SYNC MODULE to use. So, my question, is it possible to use NM-16A module with Cisco 2811 or HWIC-16A module must be used? And what is the difference between them?
I found on Cisco website that NM-16A is not supported on Cisco 2811, however some forums stated that it is possible.

Your help is deeply appreciated.
Thank you,
Arik

Hi Arik,
It is definatly supported for the 2800 series including 2811. Here is the part number and description
HWIC-8A, HWIC-16A | High-density 8-port connector | • High -density 8-port EIA-232 asynchronous cable (CAB-HD8-ASYNC) • High-density 8-port asynchronous cable with eight DB-25 modem connectors (CAB-HD8-KIT) |
For more info refer to this link:

Reza,
Thank you for your replay. Actually, my question was related to NM-16A module. I do know that HWIC-16A is supported and reason to go with NM-16A card is cost. HWIC-16A module is twice expensive than NM-16A.

Arik,
The NM-16A is supported in the older models i.e. 2600, 3600, etc...
The old NM-16A is 68 pin Octopus interface and the new ones
HWIC-8A are the smart serial connectors that is supported on 2800, 2900, 3800, etc...
