Excalibur Multirate DAP Installation and Operation

5-38

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

1. Enter front panel commands to originate a dial backup connection with the

answering DAP. See Chapter 6, "Entering Telephone Numbers" and

"Originating Dial Backup Calls" for instructions.

2. When the dial backup connection has been established, switch back to the

dedicated lines by pressing the button beneath Line in the Call submenu. Then

press the button beneath Ded. The DAP retains the dial backup connection and

returns primary channel data to the digital lines.
