•
All labeling is complete as per site requirements. Labeling is specific to each customer.
At a site with only one installation, labeling may be unnecessary. However, at sites with
multiple installations, correct and adequate labeling is essential for future maintenance
operations.
Typical labeling requirements include:
•
Antenna labels - for link identity and bearing
•
RFU labels - for link identity, frequency, and polarization
•
Coax cable labels - for link identity, close to the RFU, IDU, and either end of any joint
•
IDU labels - for link identity
Radio Link Commissioning Procedure
Scope
This section describes the recommended commissioning tests for PTP 820 radio link in a 1+0
configuration.
The purpose of the commissioning tests is to verify correct and proper operation of the product.
Commissioning Test
The following tests should be performed on each installed link.
Link Verification
•
Received Signal Level (RSL) is up to +/- 4 dB from the expected (calculated) level at both ends
of the link.
•
Radio Bit Error Rate (BER) is 10E-11 or lower.
•
If working with ATPC, ATPC is operating as expected (RSL = reference level).
Ethernet Line Interfaces Test
•
Connect Ethernet Packet Analyzer to the GbE port. Use physical loop at remote end (or connect
second analyzer). Run Packet Loss test for at least one hour (load rate as per Cambium's
specifications for the chosen MRMC).
•
Connect Ethernet Packet Analyzer to the FE port. Use physical loop at remote end (or connect
second analyzer). Run Packet Loss test for at least one hour (load rate as per Cambium's
specifications for the chosen MRMC).
Interoperability Verification
•
Connect customer end equipment to the line interfaces and verify correct operation.
•
Further interoperability tests should be performed in accordance with the specific requirements
of the connected end equipment.
Management Verification
•
Launch the HTTP management and verify that you can manage the link and that you are able to
perform changes to the link configuration (frequency channel, Tx power, system name, time &
date, etc.)
•
Verify that correct parameters are reported when performing the above.
•
Verify that there are no active alarms on the link.
•
If the management station is located at a remote site (Network Operation Center), verify that
the management station can manage the link and receive traps.
