Telephony and Fax (W35 only)
4 Telephony and Fax (W35 only)
A telephone and/or a fax machine can be connected to the Ericsson W3x
via the “Phone” or “Phone/Fax” connectors on the back of the unit.
Note: A fax must be connected to the “Phone/Fax” connector and the
operator needs to support a fax over IP function.
The telephony and the fax services will work without any further
configurations but must be supported by the subscription/network in order
to work.
If you experience problems see the trouble shooting section
7.7 –
Telephony and Fax Service.
4.1 SIM Authentication
It is possible to enter the PIN code for SIM authentication via a telephone
connected to the Ericsson W35 (instead of the WUI).
Follow the steps below to enter the PIN code using a telephone. The “PIN
required” and “PUK required” tones are described in
Table 24 – Information
Tones on the next page.
1. Pick up the telephone handset. If you hear the dial tone, you do not
need to enter any PIN. If you hear the specific “PIN required” tone,
proceed to step 2.
2. Dial * <PIN> #
If the PIN is correct, you will hear the normal dial tone, which indicates
that the voice service is activated and that it is possible to make phone
calls.
If the PIN is incorrect, you will hear the “PIN required” tone again.
Repeat step 2.
Note: If three attempts have been made with an incorrect PIN, the SIM
card is blocked and you will hear a new tone, indicating that the
PUK is required to unblock the SIM card.
To unblock the SIM card, dial the following sequence:
* <PUK> * <new PIN> * <new PIN> #
