1. Locate the Power terminal block on the rear panel of the unit and insert the
brown wire of the power supply into the +V of the terminal block.
2. Insert the black wire into the -V spring pin connector of the terminal block.
3. Ensure that the two wires are securely held by the connectors.
Wiring for Burst Synchronization
When you have either a hub configuration or a repeater site (more than one
AirLink Pro T1/E1 Rack Mount unit operating from the same central site), one of
the units must be set up as the source for burst synchronization. Refer to Chapter
3, Configuration, for Hub and Repeater configurations.
Installing the Burst Sync Wiring
The burst synchronization connections are made using unshielded twisted pair
wires. The equipment should be physically located as shown in Figure 2-12.
The primary and the backup masters should be the first units in the group. If
the distance between the primary master and the last secondary master is
greater than 100 ft, the burst sync bus(es) should be terminated at this unit (the
last secondary master).
