9.14 Hardware Connection Example 3 – Trunking between
Intercom Matrixes
The following example demonstrates the use of PG8/PG4-INTERCOM-FX devices to link intercom matrixes.
A pair of PG8-INTERCOM-FX devices is used to establish an eight channel trunk between two intercom matrixes.
The four-wire ports are transported over a fully routable ProGrid redundant ring topology network. Control for both
intercom matrixes are connected together using the ProGrid network's internal Ethernet switch with an optional
connection to a third party trunk controller.
