C.11 Testing of O4LE, if present
The AF interface O4LE is tested by applying a test signal at the input ports and measure this signal
at the output ports. To get the input signals at the local output ports a local loop is necessary. The
local loop is established according to chapter C.1.
Make a printout of the actual configuration of the equipment using HMI600 and test all ports, which
are not in the off state.
C.11.1 Service phone
The following tests must only be done, if the ‘Service phone’ is enabled.
Get the equipment in local loop operation according to chapter C.1. The service phone cannot be
tested completely in the local loop mode.
1. Pick up the phone and speak. You should hear yourself clearly. If a feedback tone
occurs, you should increase the difference between input level and output level of the
service phone in the configuration.
C.11.2 Hot line direct phone
The following tests must only be done, if the operation mode ‘Hot line direct phone’ is configured.
Get the equipment in local loop operation according to chapter C.1. This operation mode cannot be
tested completely in the local loop mode.
1. Measure the voltage at open loop condition:
Disconnect phone and take the measurement.
2. Check audibility of phone:
If the chosen phone is available, test the audibility:
Pick up the phone and speak. You should hear yourself clearly. If a feedback tone
occurs, you should increase the difference between input level and output level of the
‘subscriber, direct phone’ in the configuration.
C.11.3 ‘Remote subscriber’
The following tests must only be done, if the operation mode ‘Remote subscriber’ is configured.
Get the equipment in local loop operation according to chapter C.1. This operation mode cannot be
tested completely in the local loop mode.
1. Measure the voltage at open loop condition:
Disconnect phone and take the measurement.
2. Check audibility of phone:
If the chosen phone is available, test the audibility:
Pick up the phone and speak. You should hear yourself clearly. If a feedback tone
occurs, you should increase the difference between input level and output level of the
‘subscriber, direct phone’ in the configuration.
