How many channel groups can the VWIC support?

Re: VWIC channel group

Hi Friend,

Two channel groups can be supported per VWIC2 module. When a 2 port VWIC2 is used, only 1 channel group is supported per port.

Re: VWIC channel group

Hi Narayan

You can configure more than 2 channel group in VWIC2.The channel-group limits depend on where you insert the VWIC2.

e.g. in Case of 3800 HWIC slots: max 128 channel-groups across all 4 HWIC slots & in case of 2800 it's limited to 2 channel groups per HWIC slot.

Also limitation is per slot & not on VWIC2 port
