Configuring the Card 2-15

Menu Option 2 Restoring configuration from NVRAM

This option allows you to return the NAC to configuration settings stored in NVRAM.

Menu Option 3 Restoring the default configuration

After saving configuration changes to NVRAM, you may decide at a later date that changes need to be made. An easy way to implement this new configuration is to return the NAC to the default configuration and start fresh.

Menu Option 4 Assigning timing source priority

Each span line provides a timing source for the synchronization of data transfer. This option allows you to set the priority of each span’s timing source.

The source with the highest priority is the primary timing source for the span lines. The span with the lowest priority acts as a secondary timing source should the primary be lost.

Menu Option 5 Configuring chassis slot devices

This allows the user to configure NACs in slots 1–16 of the Total Control chassis. Only the following types of cards are configurable:

■Quad Modem Card

■Quad I-Modem Card

■NETServer PRI Card (ISDN-GW)

Use the following syntax to assign a device to a chassis slot:

dev:s# (for single assignments)

dev:s#,s#,s#,... (for multiple assignments)

Where:

dev = device type (q for Quad Modems, i for Quad I-Modems, g for ISDN gateways, or n for none)

s# = chassis slot number (1–16)
