T1 Equalization
The length in feet from the DSX point.
To set the equalization for the local unit, type the following command at the
AirLink Pro T1 prompt:
AIRLINK PRO T1/E1> set equalization operand
where operand is one of the following: 0, 133, 266, 399, or 533.
If you do not specify a value, the system assumes the default value: 0. For
example, to set the equalization for the local unit to 133, type the following
command at the AirLink Pro T1/E1 Rack Mount prompt:
AIRLINK PRO T1/E1> set equalization 133
To set the equalization of the remote AirLink Pro T1/E1 Rack Mount, use the
command:
AIRLINK PRO T1/E1> remote set equalization operand
The equalization distance is the total of the cable length from the AirLink Pro
T1/E1 Rack Mount. If there is no physical cross-connect, use half the distance to
the DTE (multiplexer, PBX, router, etc.).
