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.
