Type the option number “1”, “2” or “3” to enable or disable Outward 

Payload, Outward Line, and Inward Line Loopback. Inward Loopback is 

valid only when the IAD is in Master Mode. The IAD makes the change and 

resets the interface.

Type “4” to enable or disable receipt of ESF loopback commands. (This 

option is valid only when Framing Mode is set to ESF). The IAD saves the 

changes and redisplays the Select Loopback Configuration menu.

Press Escape to return to the T1 Configuration menu and continue with 

other configuration tasks.

To configure Transmit and Receive Channels, follow the steps below.

Type “6” on the T1 Configuration menu (Figure 4.9) to select Configure 

Transmit Channels, or “7” to select Configure Receive Channels. The 

IAD displays a message indicating the number of channels enabled, and 

displays the Channel Configuration menu (Figure 4.13).

Each option on this menu is described in detail below.

Type “1” to enable all channels, or type “2” to disable all channels. The 

IAD makes the change and resets the interface. (The menu and reset messages 
may conflict; press any key to refresh the menu.)
