The basic configuration data in block 0 contains the following information (see Figure 9):
Type of modulation and bit rate
Length of ID code
Several lock-bits
Terminator set
The customer-configuration data in block 9 contains (see Figure 10):
Lock-bit for ID code (blocks 1 and 4/1 to 4)
Lock-bit for crypto key (block 5 to 8)
Lock-bit for block 9
Password mode enable

Crypto Circuit
The crypto circuit uses the certified AUT64 algorithm to encrypt the challenge which is
written to the e5561. The computed result can be read out by the base station. Compar-
ing the encryption results of the base station and the e5561, a high-security
authentification procedure is established. This procedure requires the crypto key of the
e5561 and the base station to be equal. The crypto key is stored in blocks 5 to 8 of the
EEPROM and can be locked by the user to avoid read out or changes.
