Leased Line Menu Tree

Selecting leased line configures the unit for leased line service or service that provides a permanent connection between end points such as limited distance modem.

Follow this step-by-step procedure to configure the ISU 128 for Leased Line Clock mode and Channel rate.

Clock Mode:Slave/Master

By configuring the ISU 128 for Master timing, the ISU 128 can provide clock- ing for both ends of the phone line. This Master option is used at one end of a limited distance modem application, where two ISU 128 units are directly con- nected without the use of channel banks (see Figure 6-13). The far-end unit should be configured for Slave and it derives its clocking from the ISU 128 configured as Master.
