I have a 2811 with a Network Module (NM-2CE1T1_PRI).
I want to understand the configuration of my router (please see document attached).
I understand this is a Network Module that has to E1 ports.
There's one E1 that's configured but it is divided in channel-groups each one with two time-slots assigned.
This means that the single E1 card being used is divided into 15 interfaces, each one with the possibility to carry 128kbps of data?
Another question, how do I tell if this card can carry only data or can carry as well digitized voice?
I'm trying to understand as much as I can regarding this Router, so any assistance is appreciated.
