Hello Kennie,
1. How does the interface for data look like.
a serial interface.
if controller e1 0/1/0 is configured for unframed
controller e1
channel-group 0 unframed
a serial interface is created se0/1/0:0
if you define timeslots
controller e1
channel-group 1 timeslots 1-15
channel-group 2 timeslots 16-30
two different serial interfaces are created
ser0/1/0:1
ser0/1/0:2
2) in voice the D channel is
ser0/1/0:15 so it is different and you see the single B channels in sh ip int brief
unless you use the more modern ds0-group command to create voice ports that are groups of B channels
T1 has D channel on 23th channel
3)
controller e1 0/1/0
no shut
if you are in a lab one side has to provide the clock to the other with
clock source internal
for voice additional commands may be needed depending on the scenario
Hope to help
Giuseppe
