Technical data

The Alarm LED must indicate the SYNC Loss and BER exceeding the
defined threshold.
B.7 S
LEEP
The SLEEP command determines the sleep mode parameters. The
sleeping AW can be activated by real-time CLK, DTR/RTS lines, and
command received through TTL inputs. The user can select one, two,
or all three conditions.

ONNECT
To connect the radio unit (local or remote) through the local mainte-
nance serial port, the CONNECT command must be used.

TTL1
0 – TTL_OUT1 = logic “1”
1 – TTL_OUT1 = TTL_IN1 (received from remote unit)

TTL2
0 – TTL_OUT2 = logic “1”
1 – TTL_OUT2 = TTL_IN2 (received from remote unit)
