UPC Cablecom ISDN Anleitung Seite 49

If you have applied to upc cablecom to have your existing telephone
number transferred but you would like to use the Phone service before
the transfer, and yet still be contactable on your old number, you can
automatically redirect all incoming calls destined for your existing tele-
phone number to your pro visional number. This facility remains active
until the transfer of your number to upc cablecom Phone has been
completed. The call divert must apply to each of your phones as long as
they remain connected to the ISDN-NT device. Dial *21 [Your telephone
number]# using the handset on your existing telephone connection. All
incoming calls will now be redirected to your Phone connection. Your
current provider will charge you at the local call rate for redirecting your
calls. As soon as the transfer of your existing telephone number has been
completed calls will automatically no longer be redirected.
Now disconnect all telephones that are connected to your ISDN-NT device. The
ISDN-NT device is thus rendered inoperative and can be removed. Your previous
telephone provider will be able to advise you on disposal of the ISDN-NT device.
