Test submenu
This section lists the parameters within the “Test” submenu of the “Near
Radio” menu. The test menu allows you to disable the transmitter to perform
loopback tests.
Tx Mute
To enable or disable the transmitter.
Values: 0: enable the Tx output
1: disable (mute) the Tx output
local loopbk
To loopback local tributaries 1to 4. Loops the tributary input (data from
customer) back onto tributary output (data to customer) at local terminal. This
test checks connection to the customer equipment. This parameter has two or
four screens that refer to the “capacity” setting for the radio.
Values: 0: disabled
1: enabled
RF loopbk
When you enable the RF loopback, the system changes the Rx frequency to
match the Tx frequency. The system also changes the FAW to a different value
in order to disable reception from the far-end radio. When you disable the RF
loopback, the radio switches back to the original Rx frequency and FAW.
Values: 0: disable RF loopback
1: enable RF loopback
Rem loopbk
To loopback the remote tributaries 1to 4. Loops the remote tributary output
(data to customer) back into remote tributary input. This test checks the radio
link operation.
This loopback test does not include the remote tributary line driver or the
remote tributary line receiver. This parameter has up to four screens that refer
to the “capacity” setting for the radio.
Values: 0: disabled
1: enabled
