Nortel line side t-1

[The02KID]

How should a line side 500 port be programed.Sometime we do not get disconnected and get a reorder or buzz on the card.
The card is set to loop and connected to BT Turets.

I seem to remember someone proving this worked for Disconnect Supervision on a Line Side T1 analog port.

FTR OSP 1
FTR ISP 75
TIMP 600
BIMP 600

The book says it will work:

[tt]
Supervised Analog Lines require NT1R20AB off premise line cards. However, NT5D11AA or NT5D14AA line cards may also be used.

CLS LTDA - Line Tone Disconnect

I think this is an option you get and may need to set this on the individual ports as well.

 

[GHTROUT]

If the ISP and OSP are on, you want CLS LDTD. I remember hearing from somewhere, that having both could confuse the system you want to disco from.

There is no Ground Start on a Line Side T1

There is a option switch on the card that sets it as either ground start or loop start. It just changes the a bit and b bit around. If his bt turent can handle ground start it would probably be the best option.
