Q.
What mobile and portable radios are available for SmarTrunk
operation?
SmarTrunk supports over 50 makes and models of portable and mobile radios from
ten different manufacturers. See Appendix A for a complete listing of radios
supported by SmarTrunk II.
Q.
What equipment is required to program the SmarTrunk II controllers
and logic boards?
The ST-853 SmarTrunk II controller is programmed with a PC compatible computer,
using a DOS program available from SmarTrunk. (Mobile radio logic boards are
programmed from the radio keypad or, in some cases, from a PC in conjunction
with the radio programming software).
Q.
Is any additional equipment required to support telephone
interconnect?
No. All ST-853 controllers come fully equipped with telephone interconnect
capability. Each controller has two standard RJ-11 telephone jacks which accept
normal two wire, loop start lines from a PBX or the PSTN.
Q.
Do all SmarTrunk II subscriber radios require a DTMF keypad?
No. Group dispatch calls are placed simply by pressing PTT (Push To Talk).
Subscribers who place or receive only group dispatch calls do not need a keypad.
Only those users placing telephone calls or private calls to other users require a
radio equipped with a keypad.
Q.
Is it possible to connect a mobile radio to a standard telephone
instrument or a fax machine?
Yes. A subscriber radio may be connected to a fax machine, a standard telephone
instrument and even a computer modem if it is equipped with the ST-869 Radio/
Telephone Interface Module. The ST-869 includes both the SmarTrunk II logic board
and telephone interface circuitry providing talk battery, ring voltage and an RJ-11
phone jack. (A full-duplex subscriber radio is required when supporting modem
applications.)
