I have a system that I am trying to change the names on the telephones. Here is the info that I know:

On the main Box I see the following (I guess there are two boxes together because there are two model numbers, I really don't know too much about our system since it was here before me):
Toshiba
Model: CHSUB672A
Strata
v.1b

Toshiba
Model: CHSUE672A
Strata
v.1b

The phones are:
Teleco
Digital Key Telephone
Model UST-1010DSD

I follow the instructions in the DKT 2000-Series User manual and I cannot do anything.

I go to station 200 and do the following:
Intercom
#621
page
<ext#>
page

but I never see the userbox. As soon as I hit the #621, the LCD shows 'DATA PROGRAMMED'.

Any ideas what I need to do? Let me know if I need to get some more info. I don't do much with the phones since I am the computer guy here, but I would like to be able to change the names on the phones.

Thanks.
Scott
