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
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
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.

Change Descriptions
The following problems have been addressed and corrected in DEFINITY
Enterprise Communications Server (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 or 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
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.

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.

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.

Change Descriptions
43. The administration field used to administer a user-translated version of the
display message viewed when you use the button view feature on the
DID-view button was located on the display-messages
property-management form. The field is now located on the
display-messages view-buttons form. Only the first 24 characters of the
user-translated button view display message for the DID-view button are
retained. The last 16 characters are truncated.
44. When displaying the contents of an autodial button with a Button View
button, special characters such as "pause" did not display correctly. In
addition, characters following a "suppress special" character did not
suppress in the button view display.
45. A station with a manual exclusion soft key administered beeped when
calling a busy destination.
46. A user calling a DECT unit that was not reachable had to wait for the full
"doesn’t answer" timeout before covering or forwarding, rather than
covering or forwarding as soon as the unit was determined to be
unreachable.
47. Under heavy traffic load, if numerous (50 or more) stations went off-hook at
about the same time (10 second window) and were directed to the
attendant via the Emergency Access feature the system might reset.
48. Automatic Route Selection (ARS) calls that were administered to route
immediately were incorrectly delayed by a 3 second inter-digit timer.
49. With Centralized Voice Mail via Interswitch Mode Code, if the switch did not
have a Uniform Dial Plan (UDP) then the proper digits were not being
delivered to the Voice Mail System (VMS) (AUDIX or OCTEL) for internal
and external coverage calls. The proper digits are now delivered to the
VMS even if UDP is not enabled. The only difference is in the mode code
that is sent. If UDP is enabled then the mode codes #02 or #03 are sent. If
UDP is not enabled then only the mode code #03 is sent.
50. Calls to Computer Telephony Integration (CTI) type stations did not go to
coverage when Send All Calls (SAC) was activated.
51. When Trunk Answer Any Station (TAAS) was used outside of night service
on attendant vectored calls, the calls were not dropped from the attendant
queue.
52. Trying to remove an AWOH station with a Ringer Cutoff button active
failed; this failure happened only if Terminal Translation Initialization (TTI)
was NOT enabled in the system.
53. Calls to a VDN that terminated to an attendant split displayed the wrong
information on the console if the vector had an announcement step prior to
queueing the call to the split.
54. It was possible to remove a hunt group, even if its extension was
administered as the “VMS Hunt Group Extension” on the system-param
mode-code form. Also, the command "list usage extension” did not show
the hunt group extension, as used on the mode-code form.

55. When Cyclical Redundancy Check (CRC) errors occurred on BRI ports, the
ports were taken out of service and never put back into service.
56. It was not possible to change an ISDN trunk group to a non-ISDN trunk
group if there were many AAR/ARS patterns used in the system.
57. Some incoming trunk calls to the attendant incorrectly displayed “CALL
FROM ...” instead of the trunk group name.
58. The Route Type field appeared but was not administrable on the ip-route
form for the display, change, remove, and list functions.
59. An off-net coverage call could be answered by two different coverage
points, and all parties could be conferenced on the call. Only one coverage
point may now be on a coverage call.
60. If a QSIG diversion-rerouted call terminated to a station at the origination
PBX because of Call Forward - No Reply (CFNR), and the station was
busy, the original call at the forwarding station was dropped. The original
call to the forwarding station will now continue to ring at the forwarding
station.
61. The "list-trace station/tac" commands did not output MFC call-specific
information.
62. It was not possible to make or receive Roadwarrior calls if the system had
administered the maximum number of IP station and H.323 IP station.
63. When quickly transferring a call which was being service-observed to an
agent with auto-answer, and the agent was in a different port network
which was being observed by a different observer, both observers
remained on the call after the transfer had been completed. The second
service observer is now dropped from the call when the transfer is
completed.
64. When an incoming Direct Inward Dialing (DID) call was forwarded across a
Distributed Communications System (DCS) trunk, it would lose information
concerning its path.
65. Feature interactions between the group paging feature and certain traffic
measurements caused system traps and potentially system resets.
66. ISDN calls that were held or transferred were sometimes dropped by older
U.S. Central Office equipment because of a NOTIFY message that
DEFINITY sent to the network.
67. A transferred conference call did not invoke Enhanced Network Call
Transfer (ENCT) when the conferenced user dropped.
68. It was possible for a user to transfer an unstable (e.g. ringing) call to a
group page, thereby causing the group page to lockup in a busy state.
69. Trunk Access Code (TAC) calls that originated with measured ACD agents
reported digits to Call Management System (CMS)/Management
Information System (MIS) only if the digit timeout occurred before the call
was answered.

70. Calls queued to an attendant via direct dial to an attendant VDN were left in
queue and could not be answered.
71. If all preferences of a routing pattern with Look Ahead Routing (LAR)
enabled were busy for a data call over an ISDN PRI trunk, DEFINITY
returned Cause #58 (Bearer Capability Not Presently Available), and
Cause #58 did not trigger LAR.
72. The command “list bridge” aborted when a bridged appearance was on a
station that was unmerged, and then its former port was reused by another
station.
73. After unregistering from the Roadwarrior application, an immediate phone
call on the previously associated extension would be dropped.
74. Not all TN793 ports returned to service after an upgrade.
75. For G3si systems with Duplex Switch Processing Element (SPE) and Tone
Clocks (TC) in the Processor Port Network, if both the active SPE and the
TC were in carrier “A”, the standby SPE was in standby mode, and “A”
carrier power supply was lost, then a spontaneous WARM restart SPE
interchange would occur. However, the TC would not be interchanged
automatically. The interchange required manual intervention to bring the
dial tone back (or a wait of up to an hour for background maintenance to
detect and correct the problem).
Now, during the spontaneous WARM restart SPE interchange, if the TC
must be switched to the “B” carrier, then the “B” carrier is selected and the
system performs a COLD2 (“Tone Clock Loss”) restart to automatically
correct the problem.
76. The Advice-of-Charge (AOC) station display did not clear after an outgoing
ISDN trunk call was dropped. The AOC display is now cleared 10 seconds
after the call is dropped.
77. On certain ISDN offnet coverage and forwarding calls, the call rang
continuously and did not return to a subsequent coverage point.
78. H.323 IP trunk Station Message Detail Recording (SMDR) records
indicated that calls dropped locally even when the trunk side dropped first.
Also, H.323 IP trunks dropped slowly under timer-expiration/error-log
scenarios.
79. An endpoint registration using a non-Lucent application without an
extension number may have caused a system reset. The registration is
now rejected.
80. If a user had no administered entries in the change node-names form, but
then administered a VDN, and on page 2 pressed “HELP” in either the
Audix Name or the Messaging Server Name fields, the System Access
Terminal (SAT) logged off.
81. Certain displays potentially caused system resets.
82. An Expert Agent Selection (EAS) agent on a physical station with console
permissions was blocked from forwarding another station.

Change Descriptions
83. The switch reset when an agent exited AUX work mode.
84. Russian incoming toll intrusion on a call over a Russian 3-wire rotary trunk
to a far end BUSY subscriber caused the caller’s station to enter a
non-functional state, requiring a Busy/Release to return it to service. The
Russian incoming toll intrusion attempt is now denied unless the far end
subscriber has actually answered the call, and the caller’s station idles
correctly when the station goes on-hook.
85. Executing a "display-error" command on a large (e.g., 240 members) trunk
group could cause a system reset.
86. The Terminal Self Administration (TSA) feature could cause a system
reset.
87. If call processing tried to access vector translations at the same time that
these translations were being changed from CMS, a system reset could
occur.
88. Technicians could not clear hyperactive alarms by using the
busy/reset/release sequence on DS1 boards. The "reset board" command
now executes Test #129 (Board Restore).
89. When a call redirects to the attendant due to Direct Inward Dialing (DID) No
Answer Timeout, the display showed "a= XXX-XXX-XXXX to OPERATOR
na". The display now shows "a= XXX-XXX-XXXX to called-station-name
na".
90. When a data link was disconnected in a telecommuter phone call, the voice
call was dropped within 10-60 seconds (most often within 10-30 seconds)
following the warning of link disconnection by the endpoint. Now, the voice
call is dropped within 40-120 seconds (usually 60-90 seconds) following
the link disconnection warning.
91. The title "AAR/ AAR Shortcut Dialing" appeared on the custom form, and
has been changed to "AAR/AAR Dialing without FAC" for the same
functionality.
92. Under the following circumstances: an agent A who was observed by a
supervisor received a call and answered, talked with the customer, pushed
the transfer button and dialed an offnet number, then talked with the offnet
number. When the agent A pushed the transfer button after the supervisor
was bridged on, the call was dropped.
93. List occupancy would be very high after layer 2 would go down on a
TN2158 BRI trunk port. This high occupancy could lead to degradation or
loss of switch service.
94. Native mode H.323 IP stations were unable to make outbound calls.
