[comp.dcom.telecom] Connecting a modem to a 2 line phon

berger@clio.las.uiuc.EDU (03/31/88)

Often, the second line is the outer pair (yellow/black) of conductors,
while the primary line is the inner pair (red/green).  The wider jacks
are frequently wired the same way, unless other options are present.
If you plan to use the primary line for dialing out, you may just be
able to plug your cable into the jack, provided your modem doesn't
connect the black/yellow wires, or use them for A1 switching, etc.
