IP Network Boards

Part Number: FXVOIP-S (12-port VoIP Network Board)

Part Number: FXVOIP-L (24-port VoIP Network Board)

• The VoIP board enables a voice connection to exist through an established, site-provided

circuit connection in a LAN or WAN data arrangement.

• The board converts the telephone system’s control signaling and voice traffic into IP packets

for transport across an IP network. With this system true convergence is possible, with voice

traffic sharing available bandwidth with other forms of packetized information like video and

data.

• The Current Comdial system-to-system networking scheme dictates that the hub system

contains at least one VoIP board for each node participating in the IP telephony arrangement.

• Each node system must contain at least one VoIP board to communicate with the hub system.

• A synchronization card is not required for the operation of a VoIP connection.

• Each VoIP board is assigned its own IP address, subnet mask, and access to a default gateway

to sustain a valid IP connection across a LAN or WAN.

• Network Quality of Service issues are very important to a properly functioning VoIP board.

VoIP technology is sensitive to packet delay, loss, or corruption. IP precedence for voice

packets, proper bandwidth requirements, and other QoS issues must be maintained by the

customer’s IT specialist.
