Appendix A. Configuring the Unit for Routing

Initial Setup

It is best to configure Total Access 850 TDM 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. Follow the Layer 2 setup with the

data “routing” menus (either

BRIDGE or ROUTER). Establish packet forwarding and blocking using the

SECURITY menus. Lastly, configure the physical mappings using the DS0 MAPS menus.

The following example provides step by step instructions for configuring the Total Access 850 T1 TDM

system (

INTERFACES through DS0 MAPS) for a standard routing application. System Info and System

Config parameters should be set according to your system need. Refer to System Info on page 73 and

System Config on page 75 for more details.
