Operational Description
Example: Repeater activation initiated by the terminal
• NT and LT repeater are in power down. No Monitor Channel command is active or
pending.
• A wake-up tone is received from downstream.
• The LT repeater pulls DOUT low which is detected by the NT repeater on DIN.
• The NT repeater activates the IOM®-2 interface (see "State Transition Diagram
NT-Repeater Mode", page 175).
• The LT repeater moves to the Awake state and DOUT will be released to indicate AR
on the C/I Channel. Note that the C/I command DC must be given on DIN (see "State
Transition Diagram LT-Repeater Mode", page 174).
• Activation takes now place as described in "Activation Initiated by TE with Repeater",
page 136.
