Defining Operating Parameters

5-37

In the example shown in Figure 5-1, from the CMS system console, a request is made for

a dial backup connection with a central DAP. The central DAP is then configured to run

at V32bis+ (for units equipped with the Analog IDBU feature) and to route T7 to the

dial-up telephone line. When making the call from the CMS system console, the operator

specifically requests that main channel data NOT be switched to the dial-up telephone

line.

Figure 5-1. Secondary Channel Data Routed to Dial-Up Line

If the originating DAP has the Route Secondary Channel parameter set to ToDia and the

answering DAP has it set to W/Dat, the answering unit will honor the setting of the

originating unit if it is equipped with software revision number SSC0820 or higher. If the

answering unit is equipped with a lower software revision number, the ToDia setting is

invalid. The dial backup connection will be established, but secondary channel data will

be routed with primary channel data.

To enable this feature from the DAP's front panel, follow these steps:

1. From the Configuration Mode menu, enter the RCP submenu, press the button

beneath RoutS, then press the button beneath ToDia.

2. From the Configuration Mode menu, enter the Dial submenu, then press the

button beneath DMode. For units equipped with Analog IDBU, press the button

beneath button BIS+. For units equipped with ISDN IDBU, press the button

beneath EISDN.

Note: For units equipped with ISDN IDBU, this feature cannot be enabled when the

DAP is operating in CC64 mode.
