NOTE You might need to alter more configuration values in order to ensure correct operation,
during your AirLink Pro T1/E1 Rack Mount installation. Refer to Chapter 3 for more
information on configuring the AirLink Pro T1/E1 Rack Mount.
Aligning the Antenna
After the link pair has been turned on and configured, the antennas must be
aligned. Since most AirLink Pro T1/E1 Rack Mount paths will be line-of-sight
paths, visually align the initial antenna. In most cases, this rough alignment is
sufficient for radio units to acquire radio synchronization lock.
NOTE When the radio link between two units is active, telephones can be plugged into the OW
jacks on the AirLink Pro T1/E1 Rack Mount units permitting persons at the two sites to talk
to one another. Picking up the order wire telephone causes an audible tone (pulsed
beeping) at the remote AirLink Pro T1/E1 Rack Mount unit. This tone continues until the
telephone at the other end is picked up.
To “fine tune” the antenna alignment, perform the following procedure:
1. Insert the probes of a DC voltmeter into test points (RSS) and (ground) on
the AirLink Pro T1/E1 Rack Mount (see Figure 2-11).
