Changing ATT_DATA block

[SherWat]

I have a CS1000E at 7.6.
I DO NOT have a 2250 attendant console.
When I print the ATT_DATA in LD 21 I get

TYPE ATT_DATA
CUST 00

I would like to use DN 2000 for another purpose and would like to know what implications there would be if I change this number?

When I dial extension 2000, I get a fast busy. I did a trace on my extension when I was dialing this

I see that it was trying to dial 7700. However 7700 does not exist in our PBX. 7700 appears in the NIT_DATA block and NIT1.

So, would it be as simple as just going into LD 15 and changing the ATDN from 2000 to another number?

Thanks.

Yes, just change it to another number in LD 15 under ATT, no ramifications if it is currently giving reorder tone now. It was probably dialing 7700 because that is the NIT DN

Cool. Thanks.
