ctatest is a menu-driven interactive program. Enter one- and two-letter commands to execute Natural Access and ADI service functions. Some commands prompt the user for additional input. For example, running a tone generator requires the user to specify frequencies and amplitudes. For more information about ctatest, refer to the Natural Access Developer's Reference Manual.
ctatest can execute more than one asynchronous function concurrently. For example, you can run a tone detector (ET) and record voice (RF) simultaneously. You can abort any function by entering the respective stop command (DT and RS for tone and record).
If Clocking.HBus.ClockMode = STANDALONE, then default local connections between the DSP resources and the line interfaces are nailed up as described in Default connections.
To experiment with output and input functions simultaneously, execute two instances of ctatest. Use the swish MakeConnection command to make quad connections between two ports, one bound to each ctatest instance. Refer to the Switching Service Developer's Reference Manual for information about swish.
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.
No default connections are made for a standalone board if CT bus connectivity is enabled in the board keyword file. Use swish to connect the local network interface to the local DSP resource. You can use swish interactively, or create a script in a flat text file.
The following example of swish commands nails up the voice and signaling streams for all 24 line interfaces of an AG 2000C board that has been configured as board 0.
openswitch ag2000C = agsw 0
resetswitch ag2000C
# make voice and signaling connections
makeconnection ag2000C local:0:0..23 to local:5:0..23 QUAD
closeswitch ag2000C
exit
Connect a loop start line from a PBX or the public network as a test line to your system so you can call the test line from a telephone connected to another line.
To use ctatest:
|
Step |
Action |
|
1 |
Make sure that the board keyword file includes the following statement for the board that you will be using: TCPFiles[x] = lps0.tcp where x = the next available index. If necessary, edit the board keyword file. |
|
2 |
Start ctatest. The initial ctatest menu appears. |
|
3 |
Enter OP to create a context and open the ADI service. CTAEVN_OPEN_SERVICES_DONE is displayed on your screen. |
|
4 |
Start a protocol by entering SP. The following message appears: Enter protocol name ['nocc']: Enter the loop start protocol: lps0. The following message appears: Event: NCCEVN_START_PROTOCOL_DONE, CTA_REASON_FINISHED |
|
5 |
Place a call to the line connected to the AG 2000C board. The following message appears: Event: NCCEVN_INCOMING_CALL |
|
6 |
Initiate answering the call by entering AC. The following message appears: Number of rings [1]: |
|
7 |
Press Enter. You should hear a single ring tone. The following messages appear: Event: NCCEVN_ANSWERING_CALL |
|
8 |
Begin recording to memory by entering RM. You should hear a beep on the handset. |
|
9 |
Say "Hello World," and wait. The following message appears on the screen (you may see a different number of bytes): Event: VCEEVN_RECORD_DONE, Voice End, msec=3820. |
|
10 |
Play back your voice by entering PM. You should hear "Hello World," and ctatest displays: Event: VCEEVN_PLAY_DONE, Finished, msec=3820. |
|
11 |
Quit the test program by entering Q. |
