2
The NICA X has a separate mode of operation for performing the backup for a primary service.
There are two scenarios :-
1. Operation as a Primary and Reserve service on one codec.
2. Operation as a Reserve service to an external Primary service on a different codec.
When running in Backup mode there is a main programme loop as follows :-
A. Primary Service
to
B. Primary Service Fail
to
C. Reserve Service
to
D. Primary Service Restored or Reserve Service Failed/Stopped
to
A. Primary Service
6.1 – Custom Applications
As well as the Backup Operation the NICA X software version 2.10 onwards also has an additional operating mode
called “SM2”. This “State Machine 2” is a special mode of operation developed for a specific application now
available in the NICA X.
The Operation of SM2 is detailed in section 6.6 State Machine 2
6.2 - Backup Configuration
The unit has to be programmed correctly to operate in the required scenario. There are a number of variables in
the programming to allow users to fine tune their operation. The table below gives an overview of this.
Parameter Options
Backup Enable NORMAL/BACKUP/SM2
Primary Mode Any codec mode or none set (none set indicates primary service is external)
Primary Channel 0, 1, 2, 1or2, 1&2
Primary No.s ch1, ch2 ISDN numbers (If primary Mode is on ISDN)
Reserve Mode Any codec mode
Reserve Channel 0, 1, 2, 1or2, 1&2
Reserve No.s ch1, ch2 ISDN numbers A and B (B are alternative backup numbers)
Fail Detect external/frame/audio1/audio1or2/audio1&2/ind1/ind2/ind1or2/ind1&2
Restore Detect external/frame/audio1/audio1or2/audio1&2/ind1/ind2/ind1or2/ind1&2
Down Time 0 - 255 seconds
Up Time 0 - 255 seconds
Silence Level -24dB/-12dB/-6dB/0dB
Number of Retries 0 - 6
Monitor Function ON/OFF
Monitor Time 0 - 5 minutes
Backup Enable
If set to BACKUP this sets the NICA X into Backup operation mode. Set this to BACKUP once all your other settings
are correct. A Remote Control Command CBE can also be used to change this setting (this could be programmed
into an Opto Input or a Function Key). The SM2 setting is a custom state machine as described in section 6.6
Primary Mode
If the NICA X is providing the Primary and Reserve service then the Primary Codec Mode is set here. It could be
any valid mode from the codec mode list.
If the NICA X is providing a Reserve service to an external Primary service then the mode must be set to “ NONE
SET”.
