Routing over Leased Lines
A synchronous port can be used to connect to synchronous leased lines from
9600bps to T1 (1.544Mbps) or E1 (2.048Mbps) for continuous operation. A digital
service unit/channel service unit (DSU/CSU) must be attached to the WAN port on
the PortMaster. For more information, see the PortMaster Configuration Guide.
