NTERWORKING WITH A
DSU
AND
SWT/TRK-PQ
The Universal Trunk will also inter-work with an existing Datakit trunk module via a T1 or E1 IP-
DSU. This allows the UTM to be connected directly to a T1/E1 facility and use a remote trunk that
would require an external DSU.
Consider the following diagram:

Configuration of the UTM is as follows:
dsu type=t1 prof=s0 timing=net tsrate=64 addslot=all
trunk type=hdlc phy=dsu modtype=
restore
Please note that the above sample configuration is for a T1 line, assigns all 24 timeslots, and has
a relatively short line equalization value. These would all be adjusted accordingly in an actual
installation. The modtype selects the protocol used and needs to be consistent with the remote
module.
