Installation in Unattended Mode 94
TEI
TEI identifies the terminal endpoint identifier. If you set this value to ‘0’, the TEI is assigned
automatically (automatic mode). If you set it to any number from 1 to 64, a fixed TEI is
used (0=TEI automatic, 3=TEI 1, 5=TEI 2, 7=TEI 3, ... 19=TEI 9).
NT2
In general, the NT2 should be set to ‘1’ for the interface type Point to Point and to ‘0’ for
all other interface types, for both basic-rate adapters and primary-rate adapters. However,
specific switches might require a different setting.
NumberLen
NumberLen (Phone Number Length) specifies the length of the called number. The phone
number length includes the basic phone number and the extension. Area or country codes
are not included.
Possible settings are:
• 0 (Application): This setting indicates that an incoming call is forwarded to the
application (CAPI, WAN Miniport) directly and the application collects the digits until
the signaled phone number is complete.
• 1 to 23: This setting indicates the number of digits to collect. The adapter collects the
digits of the called number that is signaled with an incoming call and the call is not
forwarded to the application (CAPI, WAN Miniport) until the number of dialed digits
corresponds to the given phone number length.
Example: If you use an ISDN PRI line with the area code 030, the basic phone number
893617 and an extension range from 800 to 899, you have to enter the value ‘9’ for
‘NumberLen’.
The default value is ‘0’.
Permanent
Permanent specifies whether the line is operating in a switched or a leased environment.
If this parameter is set to ‘0’, a switched line is assumed. If it is set to ‘1’, a leased line is
assumed. The default is ‘0’. This parameter must be set according to the ‘IIfType’
parameter.
CRC4
This parameter is only used for primary-rate adapters. It specifies whether the information
element CRC4 is transmitted to the switch and whether CRC4 is checked in the packets
received from the switch. Possible settings are:
• 0 (Automatic): CRC4 is handled as described in the respective ISDN protocol standard
specification.
• 1 (Force Off): CRC4 is not transmitted.
• 2 (Force On): CRC4 is always transmitted.
