Buffering is only a few milliseconds, so no perceptable degradation occurs to
voice or data communications.
AirLink Pro T1/E1 Rack Mount Antenna
The antenna is usually a two-foot or four-foot solid-parabolic dish for the 5.7
GHz C-band, with a narrow beam and high gain. For other kinds of antennas,
contact your distributor.
The AirLink Pro T1/E1 Rack Mount ASCII Terminal User Interface
The AirLink Pro T1/E1 Rack Mount ASCII terminal user interface is an
EIA/TIA-232 interface that allows a terminal device or personal computer to
control and monitor AirLink Pro T1/E1 Rack Mount operation at either end of
the link. The connection to the EIA/TIA-232 interface can be either a direct
connection (device to port), or an indirect connection (device to modem to port)
for dial-up operation.
Programmed Configuration Parameters
AirLink Pro T1/E1 Rack Mount operation is governed by user-selectable
configuration and control parameters that reside in the non-volatile memory of
the unit. These parameters are displayed and controlled through a terminal
device that can access both the local and remote unit. When power is lost and
then restored, the system reconfigures itself from its protected configuration
database.
A long-life lithium battery protects all system configuration settings during
power losses. The battery is part of the non-volatile memory/real-time clock
circuitry on the digital module in the AirLink Pro T1 and has a 10-year storage
life (in the absence of power to the AirLink Pro T1/E1 Rack Mount).
Refer to Chapter 3, Configuration, for more information on changing
configuration parameter settings.
Monitoring and Diagnostic Capabilities
The AirLink Pro T1/E1 Rack Mount system constantly monitors the quality of
the wireless link, checking the receive RF signal level, bit errors, and many
other critical factors. This information is stored in an internal database of
status and performance information that the AirLink Pro T1/E1 Rack Mount
uses, in part, to derive the events that are stored in the event queue. As alarm
events occur, they are signaled through indicators on the front panel of the
