To Establish a radio link, we need configure fo llowing parameters: 1. MRMC – Modem scripts (ACM or fixed capacity, channel & modulation) 2. TX / RX frequencies – set on every radio 3. L in k ID – must be the same on both ends 4. Max. TSL – Max. allowed Transmission Signal [dBm] 5. Unmute Transceiver – Transceiver is by default muted (is not transmitting) ------------------------------------------------------------------------------------------------------To verify a radio link, we need control followi ng parameters: 1. RSL – Received Signal Level [dBm] – nominal input level is required 2. MSE- Mean Square Error [dB] 3. Current ACM profile

LINK ID – Antenna Alignment Process To avoid pointing the antenna to a wrong direction (when both links share the same frequency), LINK ID can be used to alert when such action is take.

LINK ID – Antenna Alignment Process Both IDUs of the same link must use the same Link ID Otherwise, “Link ID Mismatch” alarm will appear in Current Alarms Window
