What is the difference between HWIC-2T-C vs HWIC-2T.
I have a router 2800 IOS 12.X AND another with 15.x , but not detected the serial port :)

Hi,

Please check below URL.

HWIC-2T-C: I believe this is an hardware module designed for China. "C" stands for China.

HWIC-2T is just a replacement of HWIC-2T-C with no difference in features.

HWIC-2T-C

2-Port Serial WAN Interface Card

HWIC-2T

2-Port Serial WAN Interface Card

Requires Cisco ISR G2. See Migration Options section below.
