CONFIGURING THE ISU 512 FOR LEASED DIGITAL SERVICE

This section explains how to configure the ISU 512 when using a 2B1Q Leased Digital service or a service that provides a permanent connection between end points. This mode is only supported by the ISU 512 (U interface).

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 or LDM service; see Figure 5-3.

Clock Mode

By configuring the ISU 512 for Master timing, the ISU 512 can provide clock- ing for both ends of the phone line. This Master option is intended to be used at one end of a limited distance modem application, where two ISU 512 units are directly connected without the use of channel banks; see Figure 5-4. The far-end unit should be configured for Leased Slave and it derives its clocking from the ISU 512 configured as Leased Master timing.
