Connecting to a Two-line Phone
To record information about calls received on a two-line
phone, you can connect two systems using a triplex adapter
(Cat. No. 279-402). Each system only records information
about calls received on the line to which it is connected.
Follow these steps to connect two systems to a two-line
phone.
1. Unplug the existing telephone’s modular cord from the
modular phone jack and plug it into L1 + L2 on the triplex
adapter.
