The second bypass parameter for each access prefix (that is parameters 516, 519, 522, and 525) is
structured according to the following table:
Second Bypass
Parameter
Bit # Bypasses
Restriction #
7 Unused
6 Unused
5 Unused
4 Unused
3 7
2 8
1 9
0 10
The third bypass parameter for each access prefix (that is parameters 517, 520, 523, and 526) is
structured according to the following table:
Third Bypass
Parameter
Bit # Bypasses
Restriction #
7 11
6 12
5 13
4 14
3 15
2 16
1 17
0 18
To bypass a restriction, set the appropriate bit from the tables above to 1. If you do not wish the
restriction bypassed, set the appropriate bit from the above tables to 0. For example, suppose the
PL1877A is programmed such that mobile users cannot dial telephone numbers starting with 0
(parameter 48 = 0). Also, suppose that the PL1877A is programmed to disable the auto-dial feature
(parameter 30 = 0); also, manual dialing of telephone numbers is disabled (parameter 53 = 1).
You wish to allow one group of mobiles to manually dial telephone numbers starting with 0; however,
you do not wish them to have access to the autodial feature. On the other hand, you wish another group
of mobiles to have access to the autodial feature only.
