Appendix B: RFPI Numbers
The RFPI is constructed from 4 different variables which make up the 10 characters
(represented by N in the format
0xNN,0xNN,0xNN,0xNN,0xNN
):
• Access Rights Class (ARC), character 1
The network identity structure used by terminals in multi-cell. Private multi-cell
systems use the default value of 1.
• Equipment Installer's Code (EIC), characters 2 through 5
A preset code that allows terminals to distinguish between separate DECT networks.
The minimum value is 0000; the maximum is FFFF. The default value for the EXP1240
system is 16E6.
• Fixed Part Number (FPN), characters 6 through 8:
A geographically unique identity transmitted to DECT networks to help distinguish
between communications in different cells or chains. The minimum value is 001; the
maximum is FFF.
• Location Area Length (LAL), characters 9 and 10:
A unique code sent to the terminal during location registration to determine the size
of the cell area. The minimum value is 00; the maximum is FF.
An example RFPI would be
ARC (char 1) EIC (chars 2-5) FPN (chars 6-8) LAL (chars 9-10)
1 16E6 000 FF
The values are collapsed into a single 10-character string (116E6000FF), then the string
is separated into 5 pairs of 2 characters each:
Pair 1 Pair 2 Pair 3 Pair 4 Pair 5
11 6E 60 00 FF
Each pair is written as a 2-character HEX value (i.e.,
0x
is added to the front):
Pair 1 Pair 2 Pair 3 Pair 4 Pair 5
0x11 0x6E 0x60 0x00 0xFF
The HEX values are separated with commas, and the final result is displayed in the field
as
0x11,0x6E,0x60,0x00,0xFF
