Chapter 18 – Connecting the trunks
General information
This chapter describes how to connect trunks.
During the initial software installation, the installer has the option of loading
a default database containing pre-programmed trunk data into software. If
necessary, the default data can be modified at any time to meet the specific
needs.
For a complete description of how to modify pre-programmed trunk data,
refer to
“Chapter 24 – Changing pre-programmed data” on page 401
.
Power Failure Transfer
The NTMW07 Trunk/Line card has a built-in Power Failure Transfer (PFT)
feature, designed to operate with a loop start trunk. This feature allows the
connecting one trunk on the card to an analog telephone on the same card in
the event of a commercial power or system failure.
Note: Ground start trunks require a telephone set equipped with a
ground start button to place outgoing calls when in PFT mode.
WARNING
Use caution when installing or modifying telephone lines. Avoid
installing telephone wiring during a lightning storm. Do not install
telephone jacks in wet locations unless the jack is specifically
designed for wet locations. Never touch uninsulated telephone wiring
unless the line has been disconnected at the network interface.
