6.3.2.4 Telephone lock

Use of the telephone lock is prevented by a secret code, which must not be
confused with the "normal" PIN. When the telephone is delivered, the
secret code setting is "0 0 0 0".
You can lock the telephone on the analog port in two different ways. When
the full lock is on, no telephone numbers can be dialled or you apply the
telephone number lock of the ISDN telephone to the analog port also.
