nanoSwitch Installation Guide Extension Commissioning
Extension Commissioning
The extensions should be tested before the nanoSwitch is programmed with the customers
requirements. If the exchange has been supplied with a customer program, then this must be used
instead of the factory configuration tables, when checking the extension numbers and access
rights.
Ship’s Wiring
Before power is connected to the nanoSwitch,
All short circuits must be found and removed.
Only a Digital Multimeter (DMM) to be used for line testing
The resistance reading between the two wires of the extension should be between 17KΩ and
30KΩ. The resistance reading between either of the wires and the ship should be greater than
500KΩ.
Line Status
Once all of the wiring has been tested, power can be applied to the nanoSwitch.
The line status can be shown on the front LCD or via the USB port to a PC.
Line Testing
The inital test requires all the telephones to be on-hook.
There is two methods of testing an extension. The first method for testing extensions when the
system has been commissioned and an extension is not working. The second method is to be used
when commissioning the whole system.
Extension Test
The extension test is for use when the system has been comissioned and an extension stops
working or a new extension is added. These tests do not require any special mode on the
exchange, however the extension needs the right to use the engineering functions.
Commissioning Mode
The commissioning mode is designed to help configure a new system, when there might be
wiring errors and it is not known if all the extensions have been installed. If a printer is attached,
then a report can be generated as each extension is tested if required.
The tests will confirm that the extension is working and has been allocated the correct class of
service. All of the prompts are in English. Only one person is required for the tests, however up
to five technicians can test telephones simultaneously.
The commissioning mode is activated by entering the one of the following two codes into any
telephone:
# Distributor ID & Passcode *6 601
- commisioning mode without printing
# Distributor ID & Passcode *6 602
- commisioning mode with status printout
The commissioning mode is deactivated, by selecting option 5 from the commissioning menu.
