Hi,
The this VWICs supports a channelized capability where the T1 or E1 service can be flexibly split into two or more fractional channel groups. Thus a single physical port can provide connection to multiple sites.
As channeling capability is there , you can number the channels , otherwise you cannot split E1 into multiple channel groups.
For E1 you can support 30 channel groups.
HTH..rate if helpful..
