7 CONFIGURATION COMMAND Reference

Bit 7

Bit 6

CT Bus Clocking Mode

0

0

The CT bus interface is disabled - In this mode, the board is electrically

 

 

isolated from the other boards using the CT bus. The CT bus connection

 

 

commands may still be used, but the connections made are only visible to

 

 

this board. When using this mode, the on-board clocks are synchronized

 

 

to the source selected by bit 0 of this flags parameter.

 

 

 

0

1

Primary Master, Clock set A - The board drives CT bus clock set A

 

 

using the clock source selected by bit 0 of this flags parameter.

 

 

 

1

0

Secondary Master, Clock set B - The board is configured to drive clock

 

 

set B in Secondary Master mode. It automatically switches to become

 

 

Primary Master if the board driving clock set A fails. While acting as

 

 

Secondary Master the on-board clocks are synchronized to the CT bus

 

 

clock set A.

 

 

 

1

1

Slave, initially using Clock set A – The board uses the CT bus clocks,

 

 

which must be generated by another board on the CT bus. Initially the

 

 

board recovers from clock set A, though will switch over automatically to

 

 

recover from clock set B if set A fails.

 

 

 

Bit 13 causes the board to drive the CT_NETREF1 clocks on the CT bus when set to 1. The highest priority in-sync line interface is used as a clock source. If this bit is set to zero then the CT_NETREF1 clock is not driven. By default, liu_id=0 is the highest priority and liu_id=7 is the lowest. The priority may however be modified using the MVD_MSG_CLOCK_PRI message.

All other bits are reserved and must be set to zero. <code file>

The name of the Code File which gets downloaded to the board when it is reset. Code Files for Dialogic® DSI SPCI Network Interface Boards all use the suffix .dc3. All SS7 protocols are included in a single Code File called ss7.dc3. The selection of which protocols are run is made using the run_mode parameter below.

<run_mode>

The run_mode determines which protocols are invoked at run time.

<run_mode> must be set to one of the following tokens depending on the protocols that are required to run on the board (note that only protocols permitted to be run by the software license are allowed to run):
