TOD 8/9/A/B8C

Process Fixed part data

This TOD can only be executed if the central DECT data have already been configured
(TOD E1C)!

DECT-FP-No. Counter for the number of the FP

R/S/la:

Installation slot for the interface to the fixed part. Only interfaces 1 and 3 may
be used. The odd-numbered interfaces are occupied automatically (i.e. 1 and
2, 3 and 4).

FPID:

Fixed Part Identity. System-specific identification number of the FP (counted up
from 0000 in hexadecimal mode)

FP-Group:

Assignment to a group. If the PABX in question is unstructured (i.e. no definition
of groups/classes) a group number 0 will always be entered.

Enrolm.:

With/without enrolment. This enables the service engineer to specify indivi-
dually for each fixed part whether the enrolment of PPs is permitted or not
(increases security).
