Note:
This information is an estimation based on an established call. Slightly Higher Control values
will occur at time of call origination and termination.
Base values
• Originating from a station: 9.6 Kbps/Call (estimated)
• Terminating to a station: 5.76 Kbps /Call (estimated)
•
Originating to C.O: 11.5 Kbps/Call (estimated)
•
Terminating from C.O: 5.76 Kbps/Call (estimated)
• Keep Alive to Remote Site: 0.032Kbps (estimated)
• Other control packets for Remote Site: 4Kbps (estimated)
• G.723.1 voice: 5.3Kbps (one-way)
• G.729a voice: 8Kbps (one-way)
•
G.711 voice: 64Kbps (one-way)
The above base values are primarily used for call setup with the exception of keep alive;
0.032Kbps with no voice traffic. Connections between IP PAD are half duplex, established call
utilization is G.711 voice: 64Kbps, G.723.1 voice: 5.3/6.3Kbps, or G729a voice: 8Kbps. Peer-
to-Peer IP station calls are full duplex, compression can be specified by location numbers in
system data. Peer-to Peer IP station calls even though full duplex will utilize one-way for Bi-
directional networks such as T1. Peer-to Peer IP station calls over Asymmetrical networks such
as ADSL may realize higher bandwidth utilization, compression can be specified by location
numbers in system data.
