The Module commands are used to configure UTM connectivity to other components in the BNS
network. Support is provided for direct serial URP trunks, as well as IP-DSU trunks. The use of
Frame Relay and ATM infrastructures is supported between a pair of Universal Trunk Modules.
In general, module commands are “set and forget”, that is, they are executed once when the
module is installed and are not changed.
5.2.1 DSU
Syntax: DSU [type=]
[prof=]
[timing=]
[tsrate=<56|64>]
[addslot=]
[delslot=]
The DSU command configures the RJ48C interface with built in DSU functionality. It does not
associate a protocol with the interface, nor does it make the interface active. The DSU must be
configured before it is made active by assigning the phy (defines the physical trunk type) to the
DSU in the trunk command.
The type parameter indicates what basic framing is to be used. A value of T1 is used for
domestic 1.544 Mhz interfaces with 193 Bit Superframes. A value of E1 is used for European
interfaces at 2.048 Mhz with 256 Bit Superframes.
The prof parameter indicates the Transmission Waveform to be used with T1 transport. There is
only one E1 transport profile, which is automatically set.
The following table indicates the available waveforms used with T1 transport.
