Quick Setup Guide
Follow these 11 easy steps to set up your telephone system.
Connect the Exchange Lines
Analogue lines:
Start with the connector pair labelled ‘
Exchange 1 a b
’ on 206 or ‘
Exchange line 1
’ on 208/212.
Connect the pair to the exchange line. Polarity is not important.
ISDN lines (option):
Connect the grey ISDN socket(s) to connectors marked ‘
ISDN
’ on 206, or ‘Tx+ & Rx+ (CO3,
CO4)’ and ‘Tx+ & Rx+ (CO5, CO6)’ on 208/212.
Connect leads from ISDN socket(s) to the network ISDN box.
Connecting Extensions 206 / 208 systems only
The 206/208 systems use four-wire cabling with the correct polarity for terminals, while the 212 uses
a single pair for all extensions, SLT or system terminal.
Wire each extension on 206/208 systems as follows:
The wires labelled ‘System Terminals only’ are only required for the system terminals, not for
ordinary telephones, but should be connected if a terminal may be used in the socket in future.
Remember to connect a terminal to the master extension for system programming – extension
12 on 206 and extension 13 on 208/212.
206:
Avoid connecting ordinary telephones to extensions 11, 15 and 17, circled on the system
label. These extensions are connected directly to the exchange line in the event of a power
failure and will only work with ordinary telephones in this case.
