usually in the range of -12dB to -40dB.
• For QPSK modulation, the limit value is -10.5dB; for QAM128 modulation, the limit value
is -26dB. (Well designed and installed link has usually MSE value of -32dB and lower, so
the link runs without the errors in QAM 128 modulation). Note that MSE parameter might
display unpredictable values, if Modem sync is not set to OK status,.)
• Modem sync - Modem synchronization (ok = correct; no = no synchronization)
• HSI Interface - The type of connected HSI module to the IDU
• Actual – The status of the overall link (ok=correct)
• Historical – The status from the last alarm acknowledgement (ok = correct; warning =
there was an error in the past)
On the top of every screen, you can read the following:
• Color-coded radio icons together with colored flags and off-hand distinguished status of
the local and remote link terminal.
1. Indication of the Radio Icon: Green – OK; Red - error; Grey - inaccessible
remote device; Yellow - warning status
2. Flag A: “not-crossed A” – enabled auto restore configuration from start-up
memory W0 after continuous 10 minutes error timeout (applicable if connection
is lost)
3. Flag Status (flag below radio icon): Green – OK; Yellow – WARN (an error
occurred now); Yellow – HIST (information about previous error, the device is
OK now); Grey – N/A (flag on local side – no communication between IDU and
ODU on local side); Grey – N/A (flag on remote side – no communication
between local and remote device)
4. BAND: Indicates the low/high frequency on the local and remote side of the link
5. TxP: Transmit power
6. RxL: Received level (preferably in the range of -30dBm to -50dBm)
7. TxF: Transmitting frequency set in the allowed frequency range of each unit
8. COMMIT: Stores configured parameters to the permanent startup memory
IP Address Setup
Each IDU in the network must have its own unique IP address, defined subnet mask and the
primary route (gateway). For the link to function correctly (display of the remote device status) it
is also important to set the address of the remote device.
To setup the IP address, navigate to the main menu “IP” and the sub menu “Address”.
