Interactive test: ctatest

Demonstrates Natural Access functions, executing in asynchronous mode. Use ctatest to:

Verify proper installation and operation of the NCC service and the ADI service.
Experiment with Natural Access.
Expose working examples of Natural Access and NCC service or ADI service functions.

Usage

ctatest [options]

where options are:

Option	Use this option to...
-A xxxmgr	Specify the Natural Access service manager. Default: ADIMGR
-b n	Specify the board number n. Default: 0
-C	Notify the application through an event whenever Natural Access changes its list of internal wait objects. Default: 0
-f filename	Specify the file name to retrieve service names. Default: None
-F filename	Specify the name of the Natural Access configuration file. Default: cta.cfg
-i filename	Specify the name of the input file. This option allows you to use a file listing Natural Access test commands and data line by line, instead of entering the commands interactively.
-l	Show low-level events.
-p protocol	Specify the protocol to run. Default: nocc
-s [stream:]slot	Specify the port (DSP) address. Default: 0:0
-t d/r	Set the tracing option. Default: r d = disable tracing r = enable tracing
-v	Set the Natural Access compatibility level to 0.
-w	Wait before exit.
-?	Access Help.

Featured functions

Natural Access system functions, Voice Message service functions, and many ADI service functions are featured.

Description

ctatest is a menu-driven interactive program. Enter one- and two-letter commands to execute Natural Access and NCC service, ADI service, or VCE service commands. Some commands prompt for additional information, such as frequencies and amplitudes for tone generators. For more information about the service commands, refer to the service-specific reference manuals.

You can enter commands while asynchronous functions execute, allowing you to execute multiple asynchronous functions concurrently or to stop functions. For example, you can run a tone detector (ET) and record voice (RF) simultaneously. Abort any of these functions by entering the respective stop command (DT and RS for tone and record).

To experiment with output and input functions simultaneously, execute two instances of ctatest. For example, to interactively experiment with tone generation and detection, start a tone detector in the first ctatest instance and a tone generator in the second ctatest instance. Use the swish MakeConnection command to make the QUAD connections to connect the two ADI service ports back-to-back. Refer to the Switching Service Developer's Reference Manual for more information about swish.

Natural Access parameters can be viewed or modified (VD, PD). If the ctdaemon is running, shared system global defaults are copied to the context. Otherwise, the local compiled defaults are copied. The commands prompt you to view or modify context parameters or global defaults.

ctatest writes trace messages to ctdaemon if ctdaemon is running. Use ctdaemon or ctaSetTraceLevel (W command) to set the global or local trace mask. To loop back an application event, use ctaQueueEvent (LE command).

Procedure

The following procedure assumes you are testing on an AG 2000 board that has a 2500-type telephone connected to one of the lines.

Complete the following steps to run ctatest:

Step

Action

Start ctatest by entering the following command at the prompt:

ctatest -b n -s [stream:]slot [-p protocol] [-l]

where n is the board number, [stream:]slot is the DSP stream and timeslot, and protocol is the name of the protocol appropriate for the functions that you want to test.

A menu of one- and two-letter commands displays.

Enter CX to create a context.

Specify a context name and service sharing mode.

Enter OV to open the service.

Select a service from the list of available services.

CTAEVN_OPEN_SERVICES_DONE displays on your screen.

Enter SP to start a protocol.

Select a protocol appropriate for the functions you want to test.

NCCEVN_STARTPROTOCOL_DONE displays on your screen. The port is now ready to accept functions.

Enter the commands you want to experiment with.

The stop event fetch (SE), get one event (GE), and continue event fetch (CE) commands allow you to single step when issuing commands and retrieving events. These commands can be used to answer questions about state and event combinations.

To select a new protocol, stop the active protocol (UP command), and enter the SP command again. All functions that are active when you stop the protocol terminate. NCCEVN_function_DONE or ADIEVN_function_DONE displays for each active function.

Enter DX to destroy the context.

ctatest includes functions for retrieving commands from the keyboard and executing them. These functions include:

Function	Description
PerformFunc	Executes the keyboard commands and initiates Natural Access, NCC service, or ADI service functions.
Main	Processes options, creates Natural Access event queue, and goes into ctaWaitEvent loop.
MyPlayAccess	Voice play callback.
MyRecAccess	Voice record callback.
MyEventHandler	Displays the event and performs post-event processing (for example, closes files, prints extra information).
