The Conference Card plug-in card is designed for the O9500R, O9550 and AM3440 series. It provides two RS232 data ports, two FXS, and two E&M interfaces, which can provide up to 17 party conferencing on one slot connecting through 17 AM3440s. The conference bus provides an equivalent “order wire” function for O9500R, O9550s and AM3440s connected with E1 interfaces. Both voice and data can be transported on one NX64 kbps time slot when the voice signal is compressed using G.723.
Each conference card in the O9500R, O9550 and the AM3440 chassis provides a maximum of 3 independent conference bridges using the same Nx64K channel. Having multiple conference cards in the same O9500R or O9550 or AM3440 chassis can provide multiple independent conference bridges.
For utility, railroad, and other users, using a conference card in the O9500R, O9550 and AM3440 are equivalent to having an order wire function.
Note: Although the Conference Cards serve the same hardware function on O9500R, O9550, and AM3440, they have different firmware.
