Voice Device or Network

The voice device or network sends voice to

 

 

 

the voice port on the source IP node.

 

 

 

 

 

 

Source IP Node

The source IP node is a PathBuilder S200

 

 

 

series switch that

 

 

 

• connects directly to the voice device.

 

 

 

• connects directly to the IP network.

 

 

 

• connect directly to a frame relay network

 

 

 

supporting voice.

 

 

 

• encapsulates voice received from the

 

 

 

voice device or network using 3Com’s

 

 

 

SoTCP protocol.

 

 

 

• initiates calls to the peer, the destination

 

 

 

IP node.

 

 

 

 

 

 

Destination IP Node

The destination IP node is a PathBuilder

 

 

 

S200 series switch that receives SoTCP

 

 

 

packets sent from the source IP node over the

 

 

 

IP network. The destination IP node

 

 

 

un-encapsulates SoTCP packets and sends

 

 

 

voice traffic to the PBX.The PBX may also

 

 

 

connect to a frame relay network supporting

 

 

 

voice.

 

 

 

 

 

 

PBX

The PBX connects to the destination IP node

 

 

 

and receives voice traffic from it.
