The Information Code may be programmed to be any combination from 00 to 99.
Currently Sweden uses 00 and 10 in their standard (see details below), with the balance
reserved for future use. Any of the above modes may be overridden by dialing the prefix
code ∗67 or ∗87 (default values) prior to the destination number. In this case the following
special codes will be transmitted:
∗67 Prefix: Programmable code up to 2 digits, with programmable start and stop
digits.
Defaults:
Sweden: Code: 10 (calling party number is restricted)
Start digit: DTMF B
Stop digit: DTMF C
Netherlands:
Not used (defaults = Sweden)
∗87 Prefix: Programmable code of up to 10 digits, with programmable start and
stop digits.
Defaults:
Sweden: Code: 00 (calling number is not available)
Start digit: DTMF B
Stop digit: DTMF C
Netherlands: Code: 0000000000 (calling party is unknown)
Start digit: DTMF D
Stop digit: DTMF C
The Normal, Private, and Out of Area transmissions (see Figure 6) have programmable
Start and End digits as well as a programmable DTMF Code for the Private and Out of
Area transmissions. See Figure 39 for more information.
