11.6.1 XPIC Commissioning Tests
11.6.1.1 Individual Link Verification
Before operating in XPIC configuration, each of the links (V and H) should be
commissioned individually in order to verify its proper operation.
1 Power up only IDU V at both ends and verify its frequency channel and Tx
power configuration.
2 Verify that the RSL is no more than +/-2 dB from the expected level.
3 Run Ethernet packet loss test on the link for at least 15 minutes to ensure
error-free operation.
4 Power up only IDU H at both ends and verify its frequency channel and Tx
power configuration.
5 Verify that the RSL is no more than +/-2 dB from the expected level.
6 Run Ethernet packet loss test on the link for at least 15 minutes to ensure
error-free operation.
11.6.1.2 XPIC Configuration Verification
1 Configure the IDU MRMC with an XPIC script.
2 Verify that the RSL at all four RFUs is no more than +/-2 dB from the
expected level.
3 Verify that no alarms exist.
4 Run Ethernet packet loss test on each IDU for at least 1 hour to ensure
error-free operation.
Note:
In a 2+2 configuration, repeat each step above for each of
the four coupled RFU combinations.
11.6.1.3 XPIC Recovery Verification
In order to verify XPIC operation, simulate the faults described below.
1 Disconnect the IDU-RFU cable for each of the IDUs (one at a time), and
verify that the other link is operating.
2 Power down each of the IDUs, and verify that the other link is operating.
3 Swap the V and H cables and check that the relevant alarm is generated.
4 Mute and then un-mute one RFU at a time and verify that the other link is
operating.
Note:
In a 2+2 configuration, repeat each step above for each of
the four coupled RFUs connected to the two standby IDUs.
