All CPU levels (See Note 1, L4).
NOTES:
1. During step 4, the status of Ll to L12 LEDs
indicate the current parameters set to the trunk
group chosen. See figure below.
Ll = 10 or 20 PPS for rotary dialing
(Default: 10 PPS)
L2 = Rotary or DTMF dialing (Default: DTMF)
L3 = CO or PBX line interface (Default: CO)
L4 = Disconnect Signal from CO (YES/NO)
(Default: NO) (CPU-EBB or higher)
A disconnect signal must be sent from CO
for Trunk to Trunk transfer to operate.
L5 to L8 =
DTMF digit duration (In binary form)
(M x 50 mS.) + 60 mS.
(Default: 110 mS.)
L9 to L12= CO Hookflash time (In binary form)
(M x 100 mS.) + 300 mS.
(Default: 1500 mS.)
To adjust C.O. hookflash on a Ground Start
Trunk, the Trunk must be assigned as PBX
(LK3, ON). If the Trunk is assigned as CO
(LK3, OFF) the Hookflash will be 1,500 mS
2. See Section 350 for definitions and additional
information.
LED OFF means upper parameter

3. Depressing the ENTER key causes the display
to increment to the next trunk group.
