          Ordering Information

          The unit is designed to provide alarms, loopbacks, signal regeneration, line build out, and surge protection. The unit is suitable for wallmounting or desktop use. Five LEDs on the front of the unit (power, sync, network LOS, network Manual and remote LB, EQ LOS, EQ manual and remote LB) display the status of the unit. On the back of the unit an eight position dip switch provides settings for customer premises equipment and network line build out (LBO) distances, as well as manual loopback operation.

          The two network LBO switches provide four combination settings from 0 to 22.5dB in 7.5dB increments. The three switches allotted for the equipment LBO offer five combination settings for PBX termination at distances up to 655 feet. Two additional switches provide for manual loopback (LB) in both the Equipment (EQ) and Network (NET) directions. The last switch is a spare.
