International access function
The international access code to the PSTN (Public
Switched Telephone Network) is dialled by holding
down the <0> key until '+' appears on the display
(nominal time approx. 1 second). The access code,
thus, does not depend on the location (international
roaming).
The international access code can also be dialled
using the conventional country-specific prefix (e.g.
00 in Austria, Germany).
See "ATD Mobile originated

on the display when the terminal is idle.

Dual-tone multifrequency function
If you press the signal key during an existing con-
nection, a DTMF signal is transmitted to the remote
station. The digits entered between signal transmis-
sion and call pickup are rejected. DTMF digits are
not saved on repertory dialling keys.

The IMSI (International Mobile Subscriber Identity)
