ISDN S-interface. There will be 3 RJ-45 jacks.
♦
With ISDN, there are two voice channels for each physical connection, so only half as many
jacks are needed.
The line list in the LCD Telco menu will correspond to the installed module types, and your
configuration entries will vary accordingly.
Analog Phone Line Setup
When POTS lines are used, the only configuration required is to set the Country in the Telco
menu. This adjusts the Nx12 for correct impedance, loop current, and signaling. If your country
is not listed, try using CTR21 (a European standard) or USA.
ISDN Setup
Determine which physical circuit will represent each line of the system. It might help to fill out
the chart below before proceeding. Recall that each BRI has two voice channels, each of which
will appear to be a ‘line’ on the Desktop Director.
