Advanced Analog Networking Programming

Overview:

In the ARS Digit Modification Plans form, identify the information that you want to outpulse on the appropriate trunk type whenever an outgoing call is made on a system equipped with the AAN feature.

The following information elements are specific to the AAN feature:

• <E> where E specifies the caller's extension number

• <d> where d is the caller's dialed or default account code

• <N> where N is the system Node ID

• <R> where R is the Call Forward reason

• <F> where F is the Call Forwarder's extension number.

For more information, refer to the ARS Digit Modification Plans form.

Examples

Network Calls

When you connect two systems, AAN lets you display the calling party's extension on the receiving node's telephones and attendant consoles, provide a new COS and COR to the call, and provide centralized SMDR.

For example, complete the ARS Digit Modification Plans form as follows:

In the example, the Node ID is 1234, and the following access codes are pre-programmed onto the receiving node:

According to Digit Modification Number 1, if extension 3000 on system A calls extension 4000 on system B, the following digits are outpulsed to system B: **33000#**212343000#4000.

Display the Calling Party Extension

When the string **2<N><E># is separated out of the digit string at the receiving node, the receiving node realizes that the string between the **2 feature access code (trunk calling party identification) and the "#" character contains the identity of the party calling in on the trunk. The receiving node can then display this information at the receiving console or set.

• Note: The incoming trunks using the AAN feature must have the Trunk Calling Party Identification option enabled in their Class of Service.

Set Up Voice Mail

For example, complete the ARS Digit Modification Plans form as follows:

In the example, the following access codes are pre-programmed onto the receiving node:

The digits to be outpulsed are:

• *77 followed by one of 60,62,64,66,68 if the call is a forwarded call

• followed by a # sign

• followed by the original caller's extension number <E>

• followed by another # sign

• followed by the originally called extension which has call forwarding programmed <F>

• followed by a # sign.

• Notes:  The # is used as a delimiter.
  Information marker <E> works as it does currently. For example, if in the case of a trunk call no digits is received, then no digits will be outpulsed to the voice mail.

Provide a New COS and COR to a call

In the string **1<D>#, **1 is the programmed feature access code for an independent verifiable account code. Inserting <D> in the string ensures that the caller's dialed or default account code is used to make the call. Depending on the type of account code access code chosen (verified or non-verified), the COS/COR can be used to implement travelling class marks. Verified account codes modify the COS and/or COR of the calling station. Non-verified account codes do not affect the COS/COR and are used exclusively for call accounting purposes. In any case, the incoming account code, verified or non-verified, is stored in the SMDR record. Note that the "#" character must be used to terminate the string.

• Note: In situations where AAN is not used, an outgoing call uses the COS and COR assigned to the trunk. In a networking situation, every outgoing call from a system has the same COS and COR at the receiving node. The AAN feature enhances the features of the network by providing Travelling Class Marks that provide users with a different COS and COR at the receiving node in the network.

Provide Centralized SMDR

Because both the system Node ID (<N>), and caller's extension number (<E>), reach the receiving node, the receiving node can place this information in the SMDR record for the call.

Account Codes over ISDN

Tone plans with a time-out action of "outpulse dtmf" and no tones to detect may be used to switch from sending digits in D channel over ISDN trunks to sending DTMF account codes in B channel.

For example, complete the Call Progress Tone Detection form as follows:

In addition, insert the tone plan in the ARS Digit Modification Plans form as follows:

In the above example:

• <T01> is the instruction to switch from D channel to B channel.

• <T02> is the instruction to insert a 3-second pause.

• <A01> contains the PIN or account code, which can be replaced by <D> if AAN is used.
