TELEPHONE CONVERTER CABLES
The following diagrams show the pin-outs of various Structured Cabling Telephone
Converters. The first two telephone converters shown provide the required conversion
allowing correct operation of the attached telephone.
The third telephone converter, although universally available, uses a different bell-return
leg. This has the effect of bypassing the telephone bell circuit with the result that the
phone does not ring. This converter should not be used.
Each phone port on the ArgentPhone unit acts as a Master socket, thus only Slave
Telephone Converters are required.
