provider requests it to lessen the chance of call collisions.

Leased-Line Configuration Model

The BRI Leased Line application supports two basic modes: each B channel is routed to a different
destination or both B channels are bounded. Only one BRI-specific command is needed for this
application,

Leased S/T or U BRI line
The following commands, as shown in
channels 1 and 2 with PPP and Frame Relay encapsulation on either line. You can add other serial
interface commands as needed..
XSR(config)#interface bri 0/1/1
XSR(config-if<BRI-1/1>)#leased-line bri 0/1/1 56
XSR(config-if<BRI-1/1>)#leased-line bri 0/1/1 56

leased-line , which can be configured at 56, 64, 112, 128, or 144 Kbps.
Note: Be aware that two data streams are supported, one on each B channel, at 56 and 64 Kbps
only, and one data stream is supported over the bounded B1 + B2 or B1+B2+D line at 112, 128, or
144 Kbps only.
