1+1 Commissioning Procedure
This section describes the recommended commissioning tests for a FibeAir
radio link in 1+1 HSB (Hot Standby) configurations (internal protection).
The purpose of the commissioning tests is to verify correct and proper
operation of the product.
Note that in this section:
Primary refers to the RFUs connected to the main path of the directional
coupler in a 1+1 HSB configuration.
Secondary refers to the RFUs connected to the secondary path of the
directional coupler in a 1+1 HSB configuration.
11.5.1 Commissioning Tests
The following tests should be performed on each installed link.
11.5.1.1 Link Verification
The following steps should be repeated for each of the four RFU combinations
(Primary-Primary, Primary-Secondary, Secondary-Primary, Secondary-
Secondary).
“Link” LED and RFU LED on the IDU front panel are green, indicating the
radio link is up.
Received Signal Level (RSL) is up to +/- 2 dB from the expected
(calculated) level at both ends of the link.
Radio Bit Error Rate (BER) is 10E
-11
or higher.
If working with ATPC, ATPC is operating as expected (RSL = reference
level).
After connecting test equipment or end equipment to the line interfaces,
all LEDs on the front panel of the IDU are green.
11.5.1.2 Line Interfaces Test
10/100/200/300/400 Mbps, GbE interface - Connect a Packet Analyzer to
the GbE interfaces using an Fiber optic splitter, and verify error-free
operation (no packet loss) for at least 1 hour. Use an Ethernet loop at the
far end.
45 Mbps interface - connect PDH test equipment to the DS3 interfaces
using splitters, and verify error-free operation for at least 1 hour. Use a
physical loop between the splitters at the far end.
2 Mbps/1.5 Mbps - connect PDH test equipment to the E1/DS1 interfaces
using splitters, and verify error-free operation for at least 1 hour. Use a
physical loop between the splitters at the far end.
