This Register contains the number of rings to the phone device port after Night

Watch Mode (Register 05) has been activated. This number is usually less than

REGISTER 07 — Emergency Barge In

This register contains the mask that determines if Devices 1, 2, 3, and 4 can barge

in and gain access to the telephone line by going off-hook during a call. The four

mask bits can be set to any combination of values, allowing all, some, or none of

Devices 1 through 4 access to the line during an emergency or to just have

priority.

flags are preset to the following:

Flag 1 (Bit 3) Device 4 Barge-in Mask 0 (off)

Register 8 must also be set to a positive number to activate barge-in.
