/I

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.

3.See Section 350 for definitions and additional information.
