AP2 parameters

To program the AP2 TCP to operate within different countries and networks, modify the TCP-specific parameters, stored within the parameter category NCC.X.ADI_AP2. You can modify parameters that program TCP/host interaction, configure unregulated features, or configure features that can change from switch to switch within the same network.

Caution:

Most of the parameters that follow are signaling specific. Changing their value invalidates any approval certificate for the used board and can cause the board to malfunction. These parameters are described here for reference purposes only.


The following table describes the NCC.X.ADI_AP2 parameters (within the parameter category NCC.X.ADI_AP2):

Field

Unit

Default

Description

trunkdirection

mask

0x0

Determines trunk direction:

0 - Bidirectional

1 - Inbound only (no calls can be placed on it)

2 - Outbound only (no calls can be received on it)

startselectionduration

ms

150

Duration of proceed select pulse.

dialtoneseizureack

mask

0

Dial tone response to incoming seize.

maxwaitforfirstdigit

ms

15000

Maximum time to wait for first digit.

maxwaitfornextdigit

ms

3000

Maximum time to wait for next digit.

maxDIDdigits

count

7

Maximum number of DID (called) digits.

endofDIDtone

mask

0x00

Tone that terminates DID digits.

endselafterendtone

mask

0

Set to 1 to send end select pulse after receiving end of digits tone.

endselbeforeANIreq

mask

0

Set to 1 to send end select pulse before ANI request pulse.

endselectionduration

ms

120

Duration of end of selection pulse.

ANIrequestduration

ms

140

Duration of ANI request pulse.

maxANIdigits

count

7

Maximum number of ANI (calling) digits.

endofANItone

mask

0x00

Tone that terminates ANI digits.

meteringduration

ms

120

Duration of billing pulse.

waitingplaybusy

mask

0x1

This parameter and the waitingplayreorder parameter specify what to play as the cleardown tone (the tone the TCP plays when an inbound call is released and the calling party has not hung up yet). If this parameter is 1 and waitingplayreorder is 0, the busy tone is used as the cleardown tone.

If neither of the parameters is set, the TCP remains silent.

waitingplayreorder

mask

0x0

This parameter and the waitingplaybusy parameter specify what to play as the cleardown tone. If this parameter is 1, the fast busy (reorder) tone is used as the cleardown tone.

If neither of the parameters is set, the TCP remains silent.

detectnetworkaudio

mask

0x0

Not used.

releaseguardtime

ms

1000

Minimum time the release guard signal must be applied.

seizureacktime

ms

10000

Outbound: Specifies time to wait for seizure acknowledgment after seizing the line.

nodialtonecontinue

mask

0x0

Continue dialing if no dial tone.

dialpulsemethod

mask

0

Determines the dialing type:

0 - DTMF dialing

1 - Decadic dialing

timewaitANIrequest

ms

800

Maximum time to wait for ANI request.

usercategory

mask

0x00

ASCII user category or 0x00 if none.

tollcategory

mask

0x00

ASCII toll category or 0x00 if none.

errorearlyanswer

mask

0

If this parameter is set to 1, an answer signal before all digits have been dialed is an error, and the TCP clears the call.

answerwaittime

count

90

Not used.

bitqualtime

ms

20

Specifies the qualification time for bit changes. A or B bit must be ON/Off of this duration to be qualified.

forwardpatterns2

mask

0x1111

Bit patterns used in the forward direction (outbound): unused/unused/rering/trkoffer. Do not modify.

backwardpatterns1

mask

0xDDDD

Bit patterns used in the backward direction (inbound): ani/endsel/proceed/szack. Do not modify.

backwardpatterns2

mask

0x9D5D

Bit patterns used in the backward direction (inbound): recall/meter/answer/cong. Do not modify.

backwardpatterns3

mask

0xDDD5

Bit patterns used in the backward direction (inbound): block/frcdisc/clrback/MCTon. Do not modify.

backwardpatterns4

mask

0xD95D

Bit patterns used in the backward direction (inbound): unused/idleback/answerfree/MCToff. Do not modify.

NMScountry

count

0

Not used.

permanentsignaltime

count

60

Time (in seconds) waiting for idle, after which we go out of service.
