Zarlink products can be configured to meet standards worldwide, including custom requirements. To address such
varying system-level specifications, Zarlink provides tools like WinSLAC™ and Profile Wizard to help engineers
generate design data. The design data provided by these tools is organized into profiles to meet specific system
requirements. The data for each profile is created with the Profile Wizard application. Profiles can be generated for
the following design parameters:

The NGVCP contains internal tables for each of the profile types. This allows a fixed number (as defined in the
Profile Table section of the VoicePath™ API-II Reference Guide) of each profile type to be stored in the NGVCP.
When the host application requires the services of a particular profile for a function, it can simply refer to the profile
by its index in the NGVCP device’s profile table. Alternatively, the host application can maintain some (or all) of the
needed profiles in the host, and pass them to the NGVCP for any function call that requires them.
Once the profiles have been created, they can be compiled into the user’s application and the VoicePath™ API.
Then, the application can either load the profiles into the NGVCP, keep the profiles on the host and download them
on demand, or perform a combination of the two methods.
The VoicePath™ Profile Wizard and WinSLAC are Microsoft
NGCC Design Kit and are used to create the various profiles needed to fulfill the specific market requirements.

System Profile - The System Profile is a data array that contains set and forget parameters for the event
mask, clocks, etc., and for other global configuration options.
AC Profile - The AC Profile is a transmission characteristic profile. The AC profile holds the SLAC device’s
gain block and filter block commands and data. Each AC Profile is designed to address the specific AC
transmission requirements for a given design. In general, AC Profiles are used to address the varying
requirements of different market segments.
DC Profile - The DC Profile holds the SLAC device’s DC feed and Loop Supervision command and data.
Each DC profile is designed to address the specific DC feed and Loop Supervision requirements of a given
design. Examples of different DC feed profiles include a Constant Current Profile and a Resistive Feed
Profile.
Ringing Profile - The Ringing Profile contains the necessary commands and data to set up the ringing
generator of a SLAC device. Different Profiles can be used to vary the ringing characteristics of a line.
Options available in the Ringing Profile include: ringing waveform, frequency, amplitude, DC offset, ring trip
detector mode and a selection of internal or external ringing.
Metering Profile - The Metering Configuration Profile contains the necessary commands and data to set up
the Pulse Meter Signal Generator of the SLAC device. The parameters configured include voltage limits.
Tone Profile - The Tone Profile defines the various call progress tones that might be used in a system. The
tones include dial tone, busy, ring-back, and reorder. The Tone Profiles are used to address the market
variations that exist around the world.
Cadence Profile - The Cadence Profile defines the various cadences that might be used in a system. The
cadences may be used for call progress tones, ringing, and metering. The Cadence Profiles are used to
address market variations.
Caller ID - Defines the various Caller Line Identity (CLI) types that might be used in a system. The Caller ID
Profiles are used to address the market variations that exist around the world
NT - Includes all supported call control features.
BT - Includes all supported call control features plus the GR909 equivalent line testing.
AT - Includes all the features of the BT package plus the GR844 equivalent line testing.
ATP - Includes all the features of the AT package, additional line diagnostic tests, and a line calibration
routine for increased accuracies.
