3.4 TEL LINE CONNECTION
Macrotel Digital hybrid operates on standard POTS (Plain Old Telephone Service) / PSTN (Public Switched
Telephone Network) analog telephone lines
or an analog extension from a PBX via a standard RJ11
modular jack.
The RJ11 socket will accept 6 conductor modular plugs, but only the 2 central conductors
(typically Red &
Green ) are used.
