• —Specifies how long (in ms) to wait after the
Soft-Carrier Dekey (ms)
removal of the keying signal before actually dropping the trans-
mitter's carrier. The default setting is
value up to ms. In most cases, no change is required from the

default setting. A possible exception is when the transceiver is
inter-working with certain early-generation MDS radio equip-
ment.
• —Enables or disables the RX time-out function.
RX Time-Out Enable
RX time-out protects against a receiver which fails to receive data
for a period exceeding the RX time-out delay setting (see below).
When the time is exceeded, an alarm is issued. The alarm may be
used to signal switchover to an alternate unit in redundant sys-
tems. The RX time-out is cleared when the radio receives a new
Carrier Detect signal. The default selection is

is minutes.

• —Enables or disables the TX Time-Out function.
TX Time-Out Status
This protects against a transmitter which remains keyed for a
period exceeding the TX Time-Out Delay setting (see below).
When this time is exceeded, the transmitter is taken offline, pre-
venting disruption of the wireless network. The TX time-out is
cleared when the keying source goes away and the radio keys
again.The default selection is
