Capcode Calculation

LRS uses a combination of system ID and pager ID to identify pagers. The system ID is normally the same for every pager in the system. The pager ID identifies a particular pager, or address, within a system.

Since POCSAG uses a single address ﬁeld (the capcode) to identify pagers and addresses, the LRS system ID and pager ID combination must be mapped to a capcode.

Given the following variables:

C - POCSAG capcode
Ps - LRS system ID
Pn - LRS pager ID

The capcode calculation is as follows:


System IDs `0` through `13`	C= 100000Ps + 8Pn* + 700000
System IDs `14` through `200`	C= 100000 x ((Ps- 14)/9) + 10000((Ps− 14) mod 9)+ 8Pn* + 10000
