HASE AND FRAME CALCULATION
The method for specifying the phase and base frame of a
pager is specified in the CAPCODE type:
The phase, base frame are extracted by standard rules
from the user address field in the CAPCODE
(CAPCODE types A to L).
The phase is indicated by the CAPCODE type
(Table 25) and the base frame is specified in the frame
field of the CAPCODE (CAPCODE types U to Z).
For easy allocation of (up to 4) consecutive CAPCODEs
having the same phase and frame, an offset in the
range 0 to 3 is subtracted from the user address for the
purposes of phase and frame extraction. The offset is
determined by the CAPCODE type.
The standard rules for extracting phase and base frame
from the user address are (phase numbers 0 to 3
correspond to phases A to D):
Phase number = ((Address
Offset) DIV 4) MOD 4
Frame = ((Address
Offset) DIV 16) MOD 128
where DIV is the integer division and MOD is the
remainder of an integer division.
For a CAPCODE which does not use the standard rules for
extracting phase and base frame
(CAPCODE types U to Z) the 3-digit frame
field 000 to 127 and a single digit decimal pager
collapse 0 to 5 can precede the CAPCODE type. When
these fields are not included, the paging device or the
subscriber database must be accessed to determine the
assigned frame and collapse value.

Frame and phase extraction for different CAPCODE types
Note
1.
All-phase decoding is not defined in FLEX
G1.8 and, therefore, is not supported by the PCD5008.
