2-16CHAPTER 2: DUAL T1/PRI CONFIGURATION

The configurations made with this option are subject to verification by chassis awareness. For example, if a modem is configured that is not present in the chassis, the configuration request is automatically rejected with no error message displayed.

Menu Option 6 Configuring the modem routing method

Route incoming calls from the span to modem channels in one of three ways:

Next Available (Round Robin)

Routes calls to the very next modem channel available.

First Available (Return to Lead)

Routes calls to the lowest numbered modem channel that is first available.

Fixed Assignment (Fixed by TS)

Each T1/PRI channel is permanently assigned to a modem channel. The channels are assigned using option 8, DS0 to modem slot/chan mapping screen in the span line 1 and 2 configuration windows.

Menu Option 7 Configuring the UI console password

Configure the UI console to be password protected with this option.

In order for this option to function, set DIP switch 4 to the ON position.

See the Dual T1/PRI NAC’s Getting Started Guide for more details.

You will be prompted to enter the current password. The factory default password is intotalcontrol. You will then be prompted to enter a new password.

The password option is case sensitive.

Menu Option 8 Enabling automatic DS0 state change

Enabling this feature under fixed modem routing causes the NAC to notify the Telco that DS0s associated with modems that are no longer in service are out of service. Once the modems are available again, the DS0s assigned to those modems are placed back in service.

This option works only under the fixed modem routing method.
