Auto Detect DS0 While Protocol Down
Type “7” to automatically search for active DS0s while the T1/E1 carrier is
“up,” but the WAN layer protocol is “down.” When this option is selected, the
service provider just needs to change the active DS0 assignment on the WAN
layer. The WAN protocol should then go “down” (bounce/reset) and initiate a
new DS0 search. The DS0 search will only occur while the WAN protocol is
“down.”
Disable Auto Detect DS0
Type “8” to disable DS0 auto detection.
Start DS0 Search
Type “S” to immediately begin a search for active DS0s.
Configure Idle
Channel Code
Type “6” on the T1 Configuration menu to assign a value to idle channels.
NOTICE: Auto Detect DS0 assumes a channel is active if it sees the channel does
not contain the idle code.

Source
To Configure the Clock Source, follow the steps below.
1 Type “8” on the T1 Configuration menu to select Configure Transmit
Clock Source, which will display the Select Tx Clock Source menu (Figure

or Master mode.

E1 mode (Figure 4.19). (This menu option changes to T1 when the IAD is
configured for E1.)
