chanelised E1 configuration

[Digitel01.]

The problem  is the following:

The card controller e1 - VWIC2-1MFT-G703 is necessary to configure it for data communication, links in 64k,ie using a 1 time slot for each of the E1 link (serial interface).

But I can only create a channel-group, this topology need to create more than one (1) channel or a channel-group with multiple interfaces.

When I try to create a second channel, the device gives me the following message:

% Channel-groups per port limit Exceed

% Insufficient resources to create channel-groups

The IOS version is 15.1 (4) M15

CISCO1941/K9

VWIC2-1MFT-G703

I need to apply this setting

controller E1 0/0/0

channel-group 1 timeslots 1-2

channel-group 2 timeslots 3-4

channel-group 3 timeslots 5-6

Can you recommend another type of compatible router for this application

Thank you.

Hi,

You likely have "clock source independent" configured there. Per the following guide, when independent clocking is configured, the controller will support only one channel group and no voice applications:
