dsu bandwidth
To specify the maximum allowable bandwidth used by a T3 or an E3 controller, use the
dsu bandwidth
command in T3 or E3 configuration mode. To return to the default state, use the
no
form of this command.
dsu bandwidth kbps
no dsu bandwidth
Syntax Description
Maximum bandwidth, in kilobits per second (kbps). Range is from 75 to 44210. The
default is 44210.
kbps
Command Default
The default bandwidth is 44210.

Release 4.0.0
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
The local interface configuration must match the remote interface configuration. For example, if you reduce
the maximum bandwidth to 16,000 on the local port, you must also do the same on the remote port.
The
dsu bandwidth
command reduces the bandwidth by padding the E3 and T3 frame.
To verify the data service unit (DSU) bandwidth configured on the interface, use the
show controllers t3
or
show controllers e3
command in EXEC mode.
When G.751 framing is used on E3 links, DSU bandwidth can be used to select a payload subrate from 34,010
kbps down to 22 kbps. Before framing bypass can be used, a DSU bandwidth of 34,010 kbps must be
configured.
Although software allows the user to configure a continuous range of bandwidths in subrate modes, vendors
support bandwidths only in quantums (for example, in a ADC Kentrox T3 link, bandwidth must be in multiples
of 500 kbps). Therefore, the software sets the user-configured bandwidth to the closest vendor-supported
bandwidth. Use the
show controllers t3
or
show controllers e3
command to display the actual bandwidth
that is configured.
