1+1 Commissioning Procedure - GE HC HP User Manual

1+1 Commissioning Procedure

Scope
This section describes the recommended commissioning tests for a GE MDS Intrepid-HC HP radio link in 1+1
HSB (Hot Standby) and SD (Space Diversity) or FD (Frequency Diversity) 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.
Commissioning Tests
The following tests should be performed on each installed link.
Link Verification
The following steps should be repeated for each of the four RFU combinations (Primary-Primary, Primary-
Secondary, Secondary-Primary, Secondary-Secondary).
"Radio" LED on the IDM front panel is green, indicating the radio link is up.
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
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
IDM are green.
Line Interfaces Test
155 Mbps interface - connect SDH/SONET/ATM test equipment to the 155 Mbps interfaces
using splitters, and verify error-free operation for at least 1 hour. Use physical loop between the
splitters at the far end.
50/100/200 Mbps, GbE interface - connect a Packet Analyzer to the Fast Ethernet interfaces using
an FE splitter, and verify error-free operation (no packet loss) for at least 1 hour. Use a physical
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/T1 interfaces using splitters, and verify
