Signalling system specification
As default, CCIR tones are used within the Swedish system specifications "Alternative A" and
"Alternative C", (which are not described in this documentation).
Most of the system specifications are programmed individually for RX and TX respectively.
How to change these specifications is best shown in the examples.
The only information, which normally might needs to be changed, is timing specifications for tone-
receiver. The table "TONLEN TAB" in
MRS3000 PROGRAMMERS REFERENCE MANUAL specifies 16
different tone length intervals, which are referred, for each tone by tone-decoder see "TONE
RECEIVERS" in
MRS3000 PROGRAMMERS REFERENCE MANUAL .
There are a couple of special cases in the Alternative A and Alternative
C signalling systems:
•
After receiving ICALLINDa normally also a TSTAT_1 should be received, but this is not always
necessary, you could accept it anyway.
•
After transmitted an OCALLINDc normally the mobile answers with TSTAT_2, but it shall be OK even
if it only transmits first half of TSTAT_2.
•
After transmitted an OCALLINDb normally the mobile answers with RCPTCALL_ACK, but it is not
always needed.
The LP200/210 has to wait some time before being sure that not the rest of the answer is received, this
time is specified in "WAIT ACK TIME".
Set-up of the individual tone - call numbers to receive
The call numbers received are split into some different subgroups, depending on the action to take upon
receiving a call.
To minimize the coding effort, you are recommended to copy and use the work sheets supplied before
starting the coding. Each worksheet's header contains information of all valid destinations.
The type of call specifies which worksheet to use for it:
0:
Telephone call with fixed telephone number.
1: Alarm call to LAC. Phone number to LAC shall be set up in LAC NO 1 and LAC NO 2 (see
MRS3000 PROGRAMMMERS REFERENCE MANUAL ).
2: Telephone call with free dialling of telephone number.
3: Not used
4: Destination(s) of normal call or group call.
5: Destinations of multiline call to CUs.
8: Destination(s) for normal status delivery call and WHC.
9: Destination(s) for raised priority status delivery call.
A: Destination(s) of alarm call. (CALL_ET)
B: Alarm call to telephone number.
C: Destination(s) of alarm call with speech to CU(s). (STATREQ)
D: Not used
E: Not used
