Appendix B – Technical Information
Vibration/Tone and Vibration/Flash Pagers (POC Types)
Vibration/Tone pagers are not capable of displaying any information; they can
simply vibrate, emit a tone, or flash. In some cases, vibe/flash pagers also offer
pre-recorded voice alerts.
Numeric Pager (NUM type)
Numeric pagers are capable of displaying 1 to 16 numeric digits. It will not
display an alphabetic message. When this class of pager is targeted to receive a
page it must receive a numeric only radio transmission. If a numeric only pager
receives an alpha transmission sent to its ID, it will attempt to decode the
message and will then display nonsense on the screen. Numeric only pagers are
not ‘smart’ enough to know not to attempt to display alpha data. Therefore the
software sending the transmission must be smart enough not to send alpha data
to numeric only pagers.
Alphanumeric Pager (ALP type)
Alphanumeric pagers are capable of alpha or numeric characters with the exact
capacity based on the individual pager model, transmitter and software. Most will
display an alpha message as well as a numeric message. When this class of
pager is targeted to receive a page, it may receive either numeric only or alpha
data and if the pager is properly set up, it will display either type of data properly.
Alphanumeric pagers require special set up and adherence to special
transmission rules to properly display both alpha and numeric only radio
transmissions. The PeopleAlert can only send numeric data to an alphanumeric
pager.
Cap Codes
POCSAG (POC) pagers must receive a special seven-digit “address” to let it
know that the message that follows is for this particular pager. This “Address” is
referred to as its Cap Code. A Cap Code is the actual seven-digit numbers that
must be received by a POCSAG pager to have the pager receive a message.
The number of the pager is not necessarily the same as the Cap Code. JTECH
assigns and manages unique 3-digit prefixes to provide site uniqueness and
eliminate potential interference from other nearby businesses operating on the
same frequency.
Pager Number
Pager Number often refers to the one to four digit numbers placed on a pager label. In
systems that support cross-reference tables, the Pager Number may only be the
number on the label of the pager and only serve as a cross-reference to its actual Cap
Code.
Vibration/Tone pagers are not capable of displaying any information; they can
