TIE-TRK (Analog Tie Trunk)
NOTE:
Many trunk problems are caused by incorrect settings of parameters on the
trunk group administration form. Settings must be compatible with the local
environment and with parameter settings on the far end. The Application
Notes section of that book shows the correct settings for administrable
timers and other parameters on a country-by-country basis.
The following circuit packs, including every suffix such as TN760D, support
analog tie trunks:
Each tie trunk circuit pack occupies a port circuit pack slot and contains 4 port
circuits. Each port circuit supports 1 analog tie trunk used to connect the switch to
another PBX across 1- or 2-way dedicated circuits (see preceding list).
