All CPU levels (See L4 in Note 2).
NOTES:
1. It is recommended that 4B6 be programmed prior to
4B1, since 4B6 programming overrides all 4Bl
programming already done for all the trunks in the
group.
2. During step 6, the status of Ll to L12 LEDs indicate
the current parameters set to the CO1 channel
selected. 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
(50 mS. x M) + 60 mS.
(Default: 110 mS.)
L9 to L12 = CO Hookflash time
(100 mS. x M) + 300 mS.
(Default: 1500 mS.)
To adjust CO 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.

information.
