Specifications of different ways to dial numbers in the CUs
These set-ups are programmed local in each CU.
The 9 short numbers are programmable in 2 ways, either from keyboard as described in
MRS3000
OVERVIEW , or in programming mode, as specified in "SHORT NUMBERS" in MRS3000
PROGRAMMERS REFERENCE MANUAL.
In both cases the Route information could be included.
10 different group numbers could be specified, the corresponding call is
transmitted when pressing
|Group|. See "GROUP NUMBERS" in MRS3000 PROGRAMMERS REFERENCE MANUAL.
Tone transmitting when 2, 3 or 4 digits are dialled in the display, is normally not valid, but it can be
expanded to a full 5-digit address according to specifications in "FILL ADDRESS 2" - "FILL ADDRESS
4" in
MRS3000 PROGRAMMERS REFERENCE MANUAL .
In current version "FILL ADDRESS 0" and "FILL ADDRESS 1" are not used.
Table "FILL ADDRESS 5" could be used to always force a specific digit position to a fixed digit.
It is possible to specify default Route as power-on condition, see specification "ROUTE DIGITS" in
MRS3000 PROGRAMMERS REFERENCE MANUAL .
There are a couple of other options:
•
Possibility to prevent too ever close the loudspeaker when the handset is hung up.
•
For printer interface specify if a new-line is <CR><LF> or <LF>.
See specifications in "CU FLAGS" in
MRS3000 PROGRAMMERS REFERENCE MANUAL .
How to set up a BFS system
This is a description of how to set up a BFS system with channel 1 as the national BFS channel,
channel 4 as the local BFS channel and channel 4, 5, 6 and 7 as normal channels.
Channel 0 works only in BFS mode. On channel 0 no tone calls can be transmitted or received.
The LF from two receivers is mixed together to the CUs. It isn't possible to connect repeater traffic on
channel 0.
When channel 4 works only in BFS mode, it is possible for the operator at the CU in charge to connect
repeater traffic by pressing |Repeater| |#|, and disconnect repeater traffic by pressing |Repeater| |*|.
It is also possible to transmit tone calls, but reception of calls is disabled when in BFS mode.
The LF from two receivers is mixed together to the CUs.
On channel 4 and on channels 5, 6 and 7 the system works nearly as a normal MRS3000.
Tone calls can be transmitted and received. The only difference from a normal MRS3000 is that the
system stays in open traffic even after an operator has pressed PTT while in open traffic.
