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.

The voltage at the BNC port is 1.XX where XX is the RSL level. For example: 1.59V means an RSL of -59 dBm. Note
that the voltage measured at the BNC port is not accurate and should be used only as an aid).
