CSU/DSU

[AyrishGrl]

I have a couple of 2610s that have integrated CSU/DSU T1 cards. My question is do you have to use the integrated CSU or can you use an external Adtran or something. Our current setup has an Adtran that splits the T1 between voice and data traffic. Can the internal CSU split the T1 like that? I know you can set it to use certain timeslots, but not sure how detailed you can get.

how is your traffic being "split" do you have certain time slots dedicated for voice and certain time slots dedicated for data?

i was trying to set something up a while back where i had two circuits being delivered on a single T1 and i had to chage the default t1 wic for a different wic that had a T1 controller on it so that i could make channel groups to split the ccts it then created a subinterface for each circuit.
i had to change the WIC-1DSU-T1 card, for a VWIC-1MFT-T1.
i had two 64k circuits so this was the config i used:

controller T1 0/0
framing esf
clock source line
linecode b8zs
channel-group 1 timeslots 1 speed 64
channel-group 2 timeslots 2 speed 64

interface Serial0/0:1
description 64k Link to SiteA
ip address x.x.x.x 255.255.255.252
no shut

interface Serial0/0:2

ip address x.x.x.x 255.255.255.252
