Appendix A. Voice Gateway Quick Start Procedure (Voice Turn Up)

A typical VoATM application (see Figure 7) uses a Total Access 850 connected to an ATM network. For

voice applications, a Voice Gateway is needed to interface with the PSTN. Jetstream, Tollbridge,

CopperCom, and LES-CAS are popular Gateway types.

Figure 7. Application Diagram

To configure a Total Access 850 for use with the Voice Gateway, you need to know the VPI and VCI used

on the ATM network to access the Gateway from this Total Access 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 Total Access 850 menus for configuring the necessary elements for VoATM with the

Voice Gateway.

Perform the following steps in order to configure the application.

Initial Setup

It is best to configure Total Access 850 ATM applications by following the order of the top-level menus.

For example, first configure the system parameters using the

SYSTEM INFO and SYSTEM CONFIG menus.

Next, configure the Layer 1 parameters using the

INTERFACES menu. Once the Layer 1 information is

configured, proceed to the Layer 2 setup using the

L2 PROTOCOL menus.

The following example is for configuring T1 units with ATM firmware. However, all units

using ATM firmware (SDSL, ADSL, SHDSL) may be configured in the same manner. To

configure ATM Voice applications with other network types, disregard the T1 Interface

Setup Instructions and configure your network interface as needed.
