Using Synchronous Leased Lines 19-3
Configuration Steps for Leased Line Connections
signal, you do not need to set the speed on the synchronous port. The port speed is
whatever the carrier sends. If you choose to set a speed, it is used for administrative
notationonly and does not affect the operation of the port.
PortMaster synchronous ports support leased line connections from 9600bps to T1
(1.544Mbps) or E1 (2.048Mbps) speeds. Synchronous ports used for leased line
connections are configured for PPP operation and can have input and output filters for
network security.
Note – The PortMaster also supports numbered IP interfaces on leased lines, but Lucent
does not recommended this method because it wastes IP address space.
