4.2.2 Configuring MSI/SC Boards

4.2.2.1 Setting Hardware Configuration on MSI/SC Boards

Use ms_setbrdparm( ) to set hardware configuration, debounce times, minimum and maximum hook flash times, ring cadence patterns, and ziptone. See the Modular Station Interface API Library Reference for a description of the parameters.

MSI/SC board parameters which may be modified include:

MSG_DBONTM

Debounce on time

MSG_DBOFFTM

Debounce off time

MSG_MINFLASH

Minimum hook flash time

MSG_MAXFLASH

Maximum hook flash time

MSG_PDRNGCAD

Select the predefined ring cadence pattern

MSG_RING

Ringing capability support information

MSG_RNGCAD

Ring cadence pattern

MSG_UDRNGCAD

Set user-defined ring cadence pattern

MSG_ZIPENA

Ziptone enable

MSCB_ND

Notify on add

MSCB_ZIP

Zip tone notification

4.2.2.2 Changing Default Ring on MSI Boards

To change ring options on MSI boards, you must download a parameter file using the Intel® Dialogic® Configuration Manager (DCM). To change the default active ring cycle, you must modify the RING.PRM parameter file. To set the frequency at which the individual stations ring, you must modify the RINGFREQ.PRM file. For more details, see the Intel DCM on-line Help.

4.2.2.3 Country-Specific Parameter Files for MSI Boards

A country-specific parameter file contains a unique set of coefficients so that specific gain and impedance values are met. When a country specific parameter file is not used, the firmware automatically defaults to U.S. specifications. Each parameter file contains the calculated data for the transmit/receive gain settings, impedance scaling settings, ring frequency settings and the programmable filters of a SLAC (Subscriber Line Audio Circuit) device.
