Can somebody please clarify to me the difference between the following modules:

1-WIC-2T: 2-Port Serial WAN Interface Card

2- WIC-2A/S: 2-Port Async/Sync Serial WAN Interface Card

Also, if I need 16-port serial module, do I need to order: HWIC-16A?

One last question: what does this module do: NM-32A?

2 port serial WIC (WIC-2A/S or WIC-2T)

- The only difference between the WIC-2A/S and the WIC-2T is the maximum

supported sync speed.

- Aysnc support with a max speed of 115.2 Kbps, minimum 600 bps (use the aux

port for lower speeds).

- WIC-2A/S Sync support with a max speed of 128 Kbps.

- WIC-2T Sync support with a max speed of 2.048 Mbps.


Yes,you need to have HWIC-16A in order to have 16-port Serial Module.
