Methods of use of distribution modules for multi-wire group interconnection in telephone or like multi-wire distribution systems

The method of transferring service from one multi-wire field distribution group to another in a multi-wire communication distribution system from a central office multi-wire group without interruption of existing field service, said method comprising:

• establishing field service from a multi-wire central office group to a first multi-wire field distribution group through a prong type multi-wire bridging module terminating the end of the central office wire group by plug-in connection thereof through one side of a distribution module having at least three slotted sides, another side of which is connected a prong type bridging module terminating the end of the first field multi-wire group, and a third slotted side of which is left blank;
• connecting the prong type bridging module terminating the end of a second field distribution wire group to a blank slotted side of the distribution module without removal of the first field distribution group bridging module from the distribution module so that both field distribution wire groups are interconnected with the wire group of the bridging module of the central office wire group and thereafter unplugging the first multi-wire field distribution group bridging module from the distribution module.

The method of splicing in additional field distribution service in a multi-wire communication distribution system from a central office multi-wire group without interruption of existing field service, said method comprising:

• establishing field service from a multi-wire central office group to a first multi-wire field distribution group through a prong type multi-wire bridging module terminating the end of the central office wire group by plug-in connection thereof through one side of an at least three sided distribution module, another side of which is connecting a prong type bridging module terminating the end of the multi-wire field distribution group, and a third side of which is left blank;
• connecting one set of prongs of a double prong type extender coupler to a blank side of the distribution module and connecting a second such distribution module to the other set of prongs of the extender coupler;
• and connecting several prong type bridging modules terminating the ends of additional field distribution wire groups to the second distribution module so that all such multi-wire field distribution groups are interconnected with the bridging module of the central office multi-wire group.
