Transmitting Regular Calls:
LAM Network:
Mobile
: When calling another mobile unit, (third tone non-zero) the UT12 will send out of a base
station relay code (short first tone), followed by the ID sequence of the unit being called (long first
tone), followed by the UT12’s own ID sequence (short first tone). The base station relay code is
always 81099.
Fixed:
When calling a fixed unit (third tone zero), the UT12 will send out a home region
sequence (short first tone), followed by the ID sequence of the unit being called (short first tone),
followed by the UT12’s own ID sequence (short first tone). The home region sequence is 890HH,
where HH is the home region (00-99).
AFN Network:
AFN regular calls will consist of only one tone sequence
–
that of the unit being called. These
sequences will have a long first tone.
If the unit being called has an ID sequence of the form 8XXXX then the unit responds with a
connect tone. If there is carrier on the channel the control head will display
MIL. PHONE CALL
.
If there is no carrier within 2 seconds the control head will display
NO REPLY
