For example, a cap code of 106333 presents such a problem. We can make it a group call by adding
a 0 to the end of it (1063330). But if we want to call a pager, we must check to see in which place
the pager expects to find the diagonal tone (either tone 1 or tone 2). If it requires it to be in tone
position 1, then we would add a 1 to our call code (1063331) and the tones going out would be 569.1
Hz (diagonal from column 3) and 304.7 Hz. By putting a 2 after the call code, we can elect to have
the diagonal go in the tone position 2. Then 304.7 Hz would go out followed by the diagonal 569.1
Hz. The “X” digit is only required when the codeplan numbers “x+x” are the same, and the tone 1
and tone 2 digits are the same.
Example 3:
We are converting an existing Model 45 or Model 48 database over to the Model 748. Our first 2-
tone pager code is “11132” (T G1 G2 T1 T2) where:
T = timing 1 (1.0 0 3.0 8.0)
G1 = Group 1 (source for tone 1)
G2 = Group 1 (source for tone 2)
T1 = Tone 3 (from group 1 = 389.0 Hz)
T2 = Tone 2 (from group 1 = 368.5 Hz)
First we verify that the timing matches between the old and new. No changes required here. Next we
need to pick a Cap code from the codeplan table (see “Two-Tone Codeplans” in Section 7) based on
our existing G1 and G2. We see that G1 and G2 = 1+1. We now need to find a Cap code in the
Codeplan table (see “Two Tone Codeplans” in Section 7) that has 1+1. Looking at the table we see
that Codeplans
Z0 through Z9 all have 1+1 listed as the tone groups for a Cap code of 1xx. For this
example we will choose Code plan Z1 . We now have all the information to do the conversion.
T = Timing 1 (1.0 0 3.0 8.0)
CC = Code Plan 01 (Z1)
A = Cap code 1xx
B = Tone 3 (from group 1 = 389.0 Hz)
C = Tone 2 (from group 1 = 368.5 Hz)
So “11132” in the Model 45 and Model 48 becomes “101132” in the Model 748.
