drpinsrt

Demonstrates:

• Call transfer from an incoming line to an outgoing line using supervision monitoring.

• Using multiple queues, one per thread. (drpinsrt is not available in the SCO UNIX version of CT Access).

• Using swiCallDriver.

• Using the Switching service to make connections, send patterns, etc.

drpinsrt [options]

where options are:

Option	Description
-b n	Specifies the AG board number <n>. Default = 0
-d driver_name	Specifies the name of the driver dynamic link library. Default = agsw
-s d:i,o	Specifies the MVIP-90 stream and the incoming call timeslot and the outgoing call timeslot. Default = 18:0,2
-i protocol	Specifies the protocol to run on the incoming call side. Default = lps0
-o protocol	Specifies the protocol to run on the outgoing call side. Default = lps0

drpinsrt performs call transfer of an incoming call to an outgoing line. It uses the CT Access Switching service to connect the voice streams of two calls so that a conversation can be carried out. It demonstrates the use of swiCallDriver to use the supervision monitoring capability of the underlying MVIP-90 driver. Refer to Chapter 6 for more information about this function.

Because drpinsrt demonstrates low-level driver commands for monitoring, it uses MVIP-90 stream values.

The following procedure assumes that you:

• Are testing on an AG-8 board with a loop-start hybrid on slot 0 and a DID hybrid on slot 4.

• Have downloaded the lps0.tcp and the wnk0.tcp files to the board.

• Have a 2500-type telephone connected to the DID hybrid and some way of placing calls and accepting calls over the loop-start line (for example, with a central-office simulator with another telephone handset connected to it).

To run drpinsrt:

1. Start agmon and ensure that stream/timeslots 16:0,4 are connected to stream/timeslots 18:0,4 with quad connections.

If not, use the swish MakeConnection command to make the quad connections. Refer to Section 10.4 for more information.

2. Start drpinsrt by entering the following prompt:

drpinsrt -b 0 -s 18:4,0 -i wnk0 -o lps0

 This command uses board 0, streams:timeslot 18:4 for the incoming calls, 18:0 for the outgoing call and uses the Wink-Start protocol on the incoming call and the Loop-Start protocol on the outgoing call.


 drpinsrt displays the following:

  CT Access Multi-thread Drop and Insert Demo V.5 (Nov 4 1996)

        Outgoing Protocol    = lps0

        --------

 drpinsrt waits for an incoming call.


3.	 Put the telephone on stream/timeslot 16:4 off-hook.


 You should hear a relay click.


4.	 Dial a 3-digit telephone number.


 drpinsrt plays a message prompting you to dial an extension.

The following information is displayed:

  Event: ADIEVN_INCOMING_CALL
        Incoming Call...
        Answering call...
                        Event: ADIEVN_ANSWERING_CALL

        Playing 1 messages from 'ctademo'...

5.	 Dial an extension.


 drpinsrt informs you that it will dial that extension and then places the call on the outgoing timeslot.


 The following information is displayed:

  Event: ADIEVN_DIGIT_BEGIN, '5'
                        Event: VCEEVN_PLAY_DONE, Digit     , nbytes=0

                        Event: ADIEVN_DIGIT_END
                        Event: ADIEVN_COLLECTION_DONE, Timeout
                          digit string = '5'

                        Event: ADIEVN_STARTPROTOCOL_DONE, Finished
--------
        Placing a call to '5'...
                        Event: ADIEVN_PLACING_CALL

6.	 Answer the call on the other phone that is connected to the outgoing line via the central office simulator.

  Event: ADIEVN_CALL_CONNECTED, Voice Begin
        Connected.

 drpinsrt connects the two voice streams so that a conversation can take place. It also monitors the incoming side for hang-up using supervision monitoring.


7.	 Hang up the incoming side. The supervision monitor call returns and drpinsrt tears down the call and goes back into a Waiting for Call state.


 The following information is displayed:

  Wait_Supv return success.
                        Event: ADIEVN_CALL_DISCONNECTED, Disconnect

                        Event: ADIEVN_CALL_RELEASED

                        Event: ADIEVN_STARTPROTOCOL_DONE, Finished
