Example 4 – Two-wire PartyLine intercom over Optocore
The following example demonstrates the use of X6R/V3R-FX-INTERCOM devices to distribute two-wire PartyLine
intercom over Optocore using four-wire to two-wire PartyLine intercom interfaces.
This example shows an Optocore redundant ring topology network consisting of four V3R-FX-INTERCOM
devices connected to third party four-wire to two-wire interfaces.
The PartyLine is created by routing bi-directional audio between PartyLine interface A, connected to the first
Optocore device in the network, to PartyLine interface B, connected to the second Optocore device in the
network. This is repeated throughout the Optocore network.
The two-wire side of interfaces A and B are connected together at each position in the network and a PartyLine
has been established over the network.
The PartyLine call lights may be transported over the Optocore network using serial signalling (IC422/IC485) or
GPIO (IC444) depending on the four-wire to two-wire interfaces used.

Please note:
Audio can be routed to and from any Optocore device on the on the network.
Audio can be routed from an intercom device to any MADI, AES/EBU or analog output
on the network.
Please note:
Systems from these examples may be seamlessly integrated with all BroaMan DiViNe,
Optocore and SANE interfaces, such as the DD32R-FX AES/EBU device, DD4MR-FX
and DD2FR-FX MADI devices, X6R-FX/TP and V3R-FX/TP networkable converters.
Please note:
The four wire intercom ports are duplicated on the X6R/V3R-FX-INTERCOM devices
with reversed wiring.
This allows either matrices (TO MATRIX) or intercom key panels (TO PANELS) to be
connected to the unit using standard CAT cables, making cabling simple and cost-
effective.
