Pro-Link 64k Configuration
 

1. Starting at the main D Channel Active screen, press Set to access the menus. 2. Press 4 for the Set Line Configuration menu.


3. Press 2 for the Switch 56/64kbit modes option. Note that the current line speed setting is displayed in parentheses on the right.

1. Follow steps 1 through 3 above.

2. Press 5 to select 56k operation. The unit should take you back to the previous screen with 56kbit displayed at the right. NB: Do not choose option 4 for 56k fixed.

3. Press Esc twice to return to the main screen. Note that it may be necessary to power cycle the Pro-Link to successfully complete calls.


A couple notes about 56 versus 64k on the APT:

1. If a system set for 56 calls a system set for 64, it should work. However, if a system set for 64 calls a system set for 56, guaranteed problems will arise. 
   
   
2. When doing two simultaneous sessions (dual destination) it is imperative that all three sites involved operate at the same line speed, either 56 or 64. Otherwise one side will be muted.
