Appendix D. Voice Gateway Quick Start Procedure (Voice Turn up)
A typical VoATM application (see Figure 19) uses a TA 850 connected to an ATM network. For voice applications,
a Voice Gateway is needed to interface with the PSTN. Jetstream, Tollbridge, and CopperCom are popular Gateway
types.
Figure 19. Application Diagram
To configure a TA 850 for use with the Voice Gateway, you need to know the VPI and VCI to be used on the ATM
network to access the Gateway from this TA 850. You also need to know the format for Idle Cells and whether Data
Scrambling is used on this ATM network. The following procedure will help you navigate the TA 850 menus for con-
figuring the necessary elements for VoATM with the Voice Gateway.
