Preventing Toll Fraud

“Toll fraud” is the unauthorized use of your telecommunications system by an

unauthorized party (for example, a person who is not a corporate employee,

agent, subcontractor, or working on your company’s behalf). Be aware that there

may be a risk of toll fraud associated with your system and that, if toll fraud

occurs, it can result in substantial additional charges for your telecommunica-

tions services.

Lucent Technologies Fraud Intervention

If you suspect you are being victimized by toll fraud and you need technical sup-

port or assistance, call the appropriate BCS National Customer Care Center tele-

phone number. Users of the MERLIN®, PARTNER®, and System 25 products

should call 1 800 628-2888. Users of the System 75, System 85, DEFINITY®

Generic 1, 2 and 3, and DEFINITY® ECS products should call 1 800 643-2353.

Providing Telecommunications Security

Telecommunications security (of voice, data, and/or video communications) is

the prevention of any type of intrusion to (that is, either unauthorized or mali-

cious access to or use of your company’s telecommunications equipment) by

some party.

Your company’s “telecommunications equipment” includes both this Lucent

product and any other voice/data/video equipment that could be accessed via this

Lucent product (that is, “networked equipment”).

An “outside party” is anyone who is not a corporate employee, agent, subcon-

tractor, or working on your company’s behalf. Whereas, a “malicious party” is

anyone (including someone who may be otherwise authorized) who accesses

your telecommunications equipment with either malicious or mischievous

intent.

Such intrusions may be either to/through synchronous (time-multiplexed and/or

circuit-based) or asynchronous (character-, message-, or packet-based) equip-

ment or interfaces for reasons of:

• Utilization (of capabilities special to the accessed equipment)

• Theft (such as, of intellectual property, financial assets, or toll-facility

access)

• Eavesdropping (privacy invasions to humans)

• Mischief (troubling, but apparently innocuous, tampering)

• Harm (such as harmful tampering, data loss or alteration, regardless of

motive or intent)

Be aware that there may be a risk of unauthorized intrusions associated with

your system and/or its networked equipment. Also realize that, if such an intru-

sion should occur, it could result in a variety of losses to your company (includ-

ing, but not limited to, human/data privacy, intellectual property, material assets,

financial resources, labor costs, and/or legal costs).

Your Responsibility for Your Company’s Telecommunications Security

The final responsibility for securing both this system and its networked equip-

ment rests with you – a Lucent customer’s system administrator, your telecom-

munications peers, and your managers. Base the fulfillment of your

responsibility on acquired knowledge and resources from a variety of sources

including but not limited to:

• Installation documents

• System administration documents

• Security documents

• Hardware-/software-based security tools

• Shared information between you and your peers

• Telecommunications security experts

To prevent intrusions to your telecommunications equipment, you and your

peers should carefully program and configure your:

• Lucent-provided telecommunications systems and their interfaces

• Lucent-provided software applications, as well as their underlying hard-

ware/software platforms and interfaces

• Any other equipment networked to your Lucent products

Lucent Technologies does not warrant that this product or any of its networked

equipment is either immune from or will prevent either unauthorized or mali-

cious intrusions. Lucent Technologies will not be responsible for any charges,

losses, or damages that result from such intrusions.

Highlights

This change description document describes the changes incorporated in

DEFINITY Enterprise Communications Server (ECS), Release 8, Issue 3.0

(03.0.042.2).

Highlights of features and enhancements

Network Call Redirection

Network Call Redirection (NCR) provides the capability to have the public network

redirect an incoming call to another destination via Integrated Services Digital

Networking (ISDN), without occupying trunks between the DEFINITY and the

other location. The call redirection is invoked in real time on a call-by-call basis.

NCR uses either the ETSI Network Call Deflection (NCD) or ANSI Network Call

Transfer (NCT) features provided by the Public Switch Telephone Network

(PSTN) to redirect an incoming ISDN call from a DEFINITY to any other endpoint

via the PSTN. This optimizes the rerouting of ISDN calls over the public network,

because DEFINITY ECS trunks are not retained at the original destination after

the call rerouting takes place. Because fewer ISDN trunks are involved, the

customer realizes a cost savings.

NCR can be invoked by Best Service Routing (for NCD or NCT), Attendant

Vectoring or Call Vectoring through the “route-to

number

” command (for NCD or

NCT), Adjunct Switch Applications Interface (ASAI) Third-Party Merge/Call

Transfer using a CTI application (NCT only), or by agent or station transfers (NCT

only).

Internet Protocol (IP) Media Processor: TN2302AP

The TN2302AP circuit pack is supported by Release 8.3 software and replaces

the TN802B Media Processor, with the following proviso. The version of the

circuit pack available coincident with Release 8.3 does not support fax. The

current release of the circuit pack is intended for configurations requiring IP

station and trunk connectivity without fax. The fax version of the circuit pack is

targeted for release in September, 2000, and will work with the Release 8.3 and

later versions of the DEFINITY software base.

The TN2302AP circuit pack is the next generation H.323 IP platform. It is

designed to terminate a variety of packet audio protocols in DEFINITY Release

8.3. The circuit pack includes a 10/100 BaseT Ethernet interface and supports an

increased number of H.323 IP-compliant audio streams for IP endpoints.

In its performance, the TN2302AP circuit pack provides improved voice quality in

addition to less latency. It performs echo cancellation, silence suppression, Dual

Tone Multifrequency (DTMF, or Touch Tone) detection, and conferencing. When

used with Release 8.3 software, the circuit pack supports the following codecs,

fax detection for them, and conversion among them:

■G.711 (mu-law or a-law; 64 Kbps)

■G.723.1 (6.3 Kbps or 5.3 Kbps audio)

■G.729A (8 Kbps audio)

Three new maintenance procedures asssociated with the TN2302AP circuit pack

have been developed. These include:

■IPMEPRO — Maintenance procedures for the TN2302AP circuit pack

■MEDPRO — Maintenance procedures for TN802B circuit pack

■MEDPROPT8 — These maintenance procedures monitor the health of the

MEDPRO digital signal processors (DSPs)

For more detailed information on these maintenance procedures see What’s New

in DEFINITY Enterprise Communications Server, Release 8.3 (Document

555-233-754, Comcode 108725649, Issue 1, July 2000)

ARS/AAR Dialing Without FAC

The Automatic Route Selection (ARS)/Automatic Alternate Routing (AAR) Dialing

without Feature Access Code (FAC) feature allows the system to be administered

so that callers can place Automatic Route Selection (ARS) and/or Automatic

Alternate Routing (AAR) calls without first dialing the Feature Access Code (FAC).

The flexibility added to support this capability is intended for and supported only

for this described capability. Systems with this feature active should not activate

transfer out of the voice mail system. Additionally, other adjuncts should be

checked to verify that calls will not be allowed off-switch unintentionally.

Highlights

Issue 1 July 2000 3

ARS/AAR Dialing without FAC feature is not generally available in Release 8.3.

Although ARS/AAR Dialing without FAC appears on the customer options screen,

this feature can only be ordered and activated by using the application process

described in the Rapid Response Team website http://info.dr.lucent.com/rapid_

response/. Each customer activating this feature will go through an approval

process in which their configuration is analyzed to determine if it is a suitable

candidate for the feature.

24 Port Analog Line with Caller ID: TN793B & TN2793B

This feature allows the DEFINITY customer to view calling party information on an

analog telephone with Caller ID display. For example, the telephone number and

name of the calling party displays when this information is available from the

originating switch or central office. Time and date of call are also transmitted to

the Caller ID terminal. Calling party information, time, and date of call are

transmitted to the analog terminal via Frequency Shift Keying (FSK) signaling

following standard Bellcore or Nippon Telephone and Telegraph (NTT) protocols.

The feature requires the 24-Port Analog Line with Caller ID circuit pack TN793B

or TN2793B. The circuit pack supports Message Waiting Indication via FSK

signaling, neon lamp voltages, and the DEFINITY LED method.

The feature also requires an analog terminal with Caller ID that complies with

Bellcore or NTT protocols.

Integrated Services digital Networking (ISDN)

For analog-originated calls coming in on ISDN trunks from the NTT Network, an

administrable option on page 2 of the trunk group form now allows the PBX to

send a CONNECT message before sending the DISCONNECT message. Thus,

analog originated calls coming in ISDN trunks (so administered) from the NTT

Network will disconnect gracefully.

Centralized Voice Messaging

Release 8.3 updates the Centralized Voice Messaging (CVM) using Mode Codes

feature to work with Merlin Legend. For more information on CVM, refer to the LVI

courses BTT705B and BSS203B, and to Appendix B in Administration for

Network Connectivity, document 555-233-504.

Issue 1 July 2000 5

Change DescriptionsChange Descriptions

The following problems have been addressed and corrected in DEFINITY

EnterpriseCommunicationsServer(ECS),Release 8, Issue 3.0 (03.0.042.2).

1. When switching between PPP and X.25 type data modules, two copies of

the

Establish Connection

field on the data module form appeared.

2. If

Music on Hold

for the class of restriction for an analog station was set to

"no" and that station was bridged to a digital station, the analog station was

blocked from flashing to transfer or conference a call.

3. Analog-originated calls coming in ISDN trunks from the NTT Network did

not disconnect properly when the PBX sent an ALERT message followed

by a DISCONNECT message. An administrable option on page 2 of the

trunk group form now allows the PBX to send a CONNECT message

before sending the DISCONNECT message, for analog-originated calls

that come in on trunks in that trunk group. Thus, analog originated calls

coming in ISDN trunks (so administered) from the NTT Network will

disconnect gracefully.

4. The system could go into overload if a sufficiently large number of calls

were executing a poorly written vector (i.e., a vector with a loop not

containing a wait step). Time breaks will be inserted in vector processing

more frequently now, when the system experiences high processor

occupancy.

5. Basic Rate Interface (BRI) trunks failed to make an outgoing call, if the

network did not allocate a Terminal Endpoint Identifier (TEI) on the

previous outgoing call attempt.

6. When selecting “help” in the

AUDIX Name

Messaging Server Name

fields on the hunt group form, the help message directed the user to a

form which was no longer supported. This occurred if no “audix” or “msa”

nodes were specified on the node-names form. This help message now

directs the user to the appropriate form.

7. Attendent Direct Extension Selection (DXS) access failed if the ARS

shortcut was enabled.

Change Descriptions

6 Release 8, Issue 3.0 (03.0.042.2)

8. Automatic Route Selection (ARS) calls were blocked (caller received

reorder tone) when trunks were available but in a group controlled by the

attendant. Under these conditions, a denial event will be logged when an

ARS call fails and at least one of the trunk groups in a preference is

controlled by the attendant.

9. It was possible to remove the administration for the TN802B or TN799B

circuit packs even if an IP-interface was administered for that board.

10. VuStats could display a "percent in service" value greater than 100

percent.

11. Calls transferred to a station that covered could cause a system reset.

12. If a series of disconnects occurred in a very short time period, the Basic

Rate Interface (BRI) trunk link state was put into a state that did not handle

the hyperactive message from the packet interface board. As a result, the

link was taken out of service for about twenty minutes. Now, the

hyperactive state is handled and the link is taken out of service for about

one minute.

13. Some calls to the attendant console could not be answered by the

attendant, leaving the console locked up for several minutes until an audit

cleared the condition. Now, if a console is in a temporary state where a

new call can’t be answered, all incoming calls are directed to another

console until the condition clears.

14. There were two display messages for which translations were not

available.

15. If temporary bridged appearance for call pickup is set to "no" for the

system, users were blocked from sending digits end-to-end using an

auto-dial button, if the call was answered using a call pickup button.

16. If IP-Softphone A was bridged to another Station B, and C called B, then A

answered. If another Station D called B and hung up after a ring, the call

from C to A also dropped.

17. A DEFINITY Wireless Business Systems (DWBS) user on a switch

configured for Russian country-specific options did not get the Russian

interdigit timeout.

18. It was impossible to invoke Automatic Callback (ACB) over a QSIG Basic

Rate Interface (BRI) trunk after a “reset system 2”. It was necessary to

re-administer the maximum number of Non-Call Associated (NCA)

Temporary Signaling Connections (TSCs) for the BRI trunk to get QSIG

ACB working again.

19. The following statements:

1) It was possible to list all administered IP SoftPhones using the “list

multimedia ip-softphone” command.

2) Access to the “list multimedia ip-softphone” command was blocked

using the “mm-ip-softphone” keyword on the permissions form.

Change Descriptions

Issue 1 July 2000 7

3) The Maximum allowed IP SoftPhones was controlled via the

“Maximum IP SoftPhones” field on the system-parameters

customer-options form.

have been changed to:

1) It is possible to list all administered IP SoftPhones using the “list

multimedia ip-station” command.

2) Access to the “list multimedia ip-stations” command is blocked using

the “mm-ip-stations” keyword on the permissions form.

3) The Maximum allowed IP SoftPhones is controlled via the “Maximum

IP Stations” field on the system-parameters customer-options form.

20. If the board/port assigned to the attendant console was busied/released by

maintenance and a trunk group was under attendant control (ACTGA), the

control lamp for the Direct Trunk Group Select (DTGS) button cleared, but

the trunk group was still under control of the attendant.

21. The bridged appearance button(s) on AWOH stations were not updated to

the current call state when the station was associated to a port.

22. Attendant extended calls to a Do Not Disturb (DND) station connected the

attendant to the busy tone, even though the system was administered to

direct the call to the attendant group; in addition the system blocked post

activation of the priority calling feature. For the call scenario described

above the call will now be directed to the attendant group, which will allow

the attendant to aciviate the priority button to override the restriction and

ring the station.

23. If a call came into a VDN, followed the vector, and then was queued, but

the caller hung up before an agent answered, the queue call lamps of the

BRI set continued to flash with no calls in queue.

24. The conversion of AAR/ARS routing tables was incorrect for some

configurations when upgrading to R7/R8.

25. A user was unable to login as an ACD agent from a DECT handset.

26. When the Answer Detection by Call Classification feature was activated on

an outgoing Wide Area Telephone Service (WATS) trunk type personal

Central Office (CO) line, the call failed to reach the intended destination

because some digits were outpulsed twice.

27. Touch-Tone Receiver (TTR) queue processing could cause a system reset.

28. If a Telecommuter’s voice link was a trunk without answer supervision, after

the answer supervision time out, the IP SoftPhone automatically answered

the call. The user must now answer both IP SoftPhone and voice link to

get the call for trunks without answer supervision.

29. Users tracing a call with the "list-trace-sta/tac" command that resulted in a

“denial ...” message (caller connected to reorder or intercept tone) had to

execute the "display-event-denial" command to display the event

description. The denial event description is now displayed in the trace

output following the denial message.

Change Descriptions

8 Release 8, Issue 3.0 (03.0.042.2)

30. Tandem trunk calls that received an ALERT followed by a DISCONNECT

that had a progress indicator IE did not send a CONNECT message back

to the orginator before the DISCONNECT, even though the incoming trunk

was administered to do so.

31. Under some conditions, call record exhaustion occurred.

32. When the Long Hold Recall feature was active and a Digital

Communications Protocol (DCP) station had the “Active Station Ringing”

field set to ‘silence’, and the station put a call on hold, when the long hold

recall timer expired, the station received a continuous audible ring.

33. Systems with a CLAN in an Expansion Port Network (EPN) occasionally

found that calls were denied for a theoretical lack of bandwidth. Socket

bandwidths are now more accurately represented, resulting in no more

denials unless bandwidth is actually in short supply.

34. If Path Replacement happened to remove a network loop, the display on a

station could change to just a trunk group.

35. With Centralized Voice Mail via Interswitch Mode Code, if an incoming call

from the PSTN to a station on the Legend covered to the voice mail on the

DEFINITY, the caller received the wrong greeting ("press *H"), because the

Legend was not sending the CPN IE in the SETUP message to the

DEFINITY.

36. If TN802 was in the Prologix cabinet in slot 7 and there was another board

in slot 5, there was a conflict alarm generated against the reserved slot in

slot 5. Slot 5 can now have any board when slot 7 contains the TN802,

and no alarm is generated. The "list configuration" and "change

circuit-pack" commands properly show only one reserved slot (slot 6) in

this configuration.

37. Calls answered via call pickup were not correctly dropped when the

originator dropped.

38. Users that put bridged calls on hold on a coverage module and then

attempted to conference or transfer the call could put the station in a state

that prevented using the conference or transfer buttons again until the set

was busied and released during maintenance.

39. When a party dialed itself and redirected to a coverage point that was also

itself, the switch reset. Now, the call will be dropped and the calling party

will receive re-order or intercept tone.

40. If a party on a call activated an autodial button to dial some digits, the

listen-only service observer did not hear the DTMF digits.

41. Moving agents from one split to another via CMS could cause the switch to

reset.

42. Occasionally, when making an IP SoftPhone call, if the caller did not send a

digit to the switch after off-hook, the switch kept the call up indefinitely,

rather than timing out.
