The screenshot of page 3 of the trunk group screen

Abandoned Call Search

Indicates whether this trunk group conducts an Abandoned Call Search to identify ghost calls. Abandoned Call Search is designed to work with analog ground-start local telephone company central office (CO) trunks that do not provide disconnect supervision. The CO must support Abandoned Call Search for the feature to work properly. If the CO provides disconnect supervision, the Abandoned Call Search feature is not needed.

Available only for ground-start type trunks.

ACA Assignment

Indicates whether Automatic Circuit Assurance (ACA) measurements are taken for this trunk group.

Charge Conversion

Available only for outgoing or two-way CO, DIOD, FX, and WATS trunk groups. Also available for isdn trunk groups, if the Charge Advice field is set to a value other than none.

Valid Entry

Usage

1 to 64

500

Communication Manager multiplies the number of charge units by the value of this field and displays it as a currency amount. Without a value in this field, Communication Manager displays the number of charge units without converting it to currency.

Charge Type

Text string used to describe charges related to a telephone call. These words or characters appear on telephone displays after the charge amount. Typically uses either the currency symbol or the charge type, but not both. Accepts up to seven characters. Embedded spaces count as characters.

Available only for outgoing or two-way CO, DIOD, FX, and WATS trunk groups.

Connected to CO

Enables or disables overlap sending to a local telephone company central office (CO).

Available only for tie trunk groups.

Currency Symbol

The telephone displays the symbol before the charge amount. Accepts from one to three characters. Leading and embedded spaces count as characters.

Available only for outgoing or two-way CO, DIOD, FX, and WATS trunk groups. Also available for ISDN trunk groups, if the Charge Advice field is set to a value other than none.

Data Restriction

Enables or disables data restriction that is used to prevent tones, such as call-waiting tones, from interrupting data calls. Data restriction provides permanent protection and cannot be changed by the telephone user. Cannot be assigned if Auto Answer is administered as all or acd. If enabled, whisper page to this station is denied.

Decimal Point

The appropriate representation for a decimal point as telephone displays it. Available only with outgoing or two-way CO, DIOD, FX, and WATS trunk groups. Also available for isdn trunk groups, if the Charge Advice field is set to a value other than none.

Note:

If the received charge contains no decimals, no decimal point is displayed (that is, the administered decimal point is ignored for charge information received with no decimals). On a QSIG trunk group, unlike other trunk groups, the Decimal Point field is independent whether the calling display shows a decimal point. Instead, it tells what symbol should be displayed if the QSIG AOC received has a 1/10 or 1/100 or 1/1000 Multiplier.

Valid Entry

Usage

comma

If the received charge contains decimals, the charge is displayed at the calling endpoint’s display with a comma as the decimal point. Divides the charge value by 100.

period

This is the default. If the received charge contains decimals, the charge is displayed at the calling endpoint’s display with a period as the decimal point. Divides the charge value by 100.

none

No decimal point is displayed.

DS1 Echo Cancellation

Enables or disables echo cancellation on a per port basis. If enabled, reduces voice call echo.

Note:

Changes to the DS1 Echo Cancellation field is incomplete until one of the following occurs:

  • Port is busied-out or released.

  • Trunk group is busied-out or released.

  • SAT command test trunk group is performed.

  • Periodic maintenance runs.

DSN Term

Enables or disables the trunk group as a DSN termination telephone. The default is disabled.

Glare Handling

Determines the reaction of Communication Manager to glare.

The following circuit packs can detect glare:

  • TN767 (all releases)

  • TN760C (or later releases)

  • TN464C (or later releases)

Available only for two-way trunks when the outgoing side of the Trunk Type is either …/wink or …/delay.

Valid Entry

Usage

control

Communication Manager seizes the trunk and proceeds with call setup. The other switch finds another trunk.

backoff

The other server or switch seizes the trunk and proceeds with call setup. The server or switch finds another trunk.

none

Not administered.

Hold/Unhold notification

Use this field to enable Communication Manager to send a notification to the far end SIP endpoint when the far end SIP endpoint is put on hold or unhold.

When you upgrade to Communication Manager Release 8.1.3, the Hold/Unhold Notifications field is not visible for all SIP trunks and the existing values for all sip trunks are reset to n. For the Hold/Unhold Notifications field to be visible for all SIP trunks, you must enable the SA9143 Hold/Unhold Notifications for SIP Trunks field on the system-parameters special-applications screen. .

The default value of Hold/Unhold Notifications field on the trunk group for SIP trunks is n. For example, if you add a new SIP trunk when SA9143 Hold/Unhold Notifications for SIP Trunks field is already enabled, the value in the Hold/Unhold Notifications field appears as n.

The Hold/Unhold Notifications field appears for all SIP trunks, only if the SA9143 Hold/Unhold Notification for SIP Trunks field on the system-parameters special-applications screen is set to y. Also, if the Hold/Unhold Notifications field for any SIP trunk-group is set to y, then you cannot disable the SA9143 Hold/Unhold Notifications for SIP Trunks field on the system-parameters special-applications screen. For more information, see Avaya Aura® Communication Manager Special Application Features document.

Valid entry

Usage

y

Communication Manager sends the reINVITE to the far end SIP endpoint to notify the far end SIP endpoint that the endpoint is put on hold or unhold. The media direction in this reINVITE is sendonly when Music On Hold is enabled and is inactive when Music On Hold is disabled. When far end SIP endpoint is put on unhold then reINVITE with media direction sendrecv is send.

n

Communication Manager does not send the reINVITE to the far end SIP endpoint. The default value is n.

Incoming Tone (DTMF) ANI

Digits received through Automatic Number Identification (ANI) are printed on a CDR record, passed to the Intuity Audix and ASAI interfaces, and displayed on the telephone (and on tandem calls if the outgoing trunk requires ANI). Then the digits are sent to the outgoing trunk.

Available only if the Incoming Dial Type is tone.

Valid Entry

Usage

*ANI*DNIS*

If 555-3800 calls extension 81120, the trunk group receives *55538000*81120*. The telephone displays Call from 555-3800.

ANI*DNIS*

If 555-3800 calls extension 81120, the trunk group receives 55538000*81120*. The telephone displays Call from 555-3800.

no

Not administered.

Internal Alert

Indicates if internal ringing and coverage is used for incoming calls.

Invoke ID for USNI Calling Name

Communication Manager uses the Invoke ID for USNI Calling Name field to select an Invoke ID each time a calling name is sent over the ISDN trunk group using the USNI protocol.

The system displays the Invoke ID for USNI Calling Name field only when:

  • The Group Type field is set to ISDN.

  • The Carrier Medium field is set to PRI/BRI.

  • The Supplementary Service Protocol field is set to a.

However, the valid entries, variable and fixed-1, have an impact only when the following conditions are met:

  • On the Feature-related system parameters screen, the USNI Calling Name for Outgoing Calls field is set to y.

  • On the Trunk group screen, the Send Name field is set to y.

Valid entry

Usage

variable

Communication Manager selects a new Invoke ID each time a calling name is sent over the ISDN trunk group. This entry is the default value.

fixed-1

Communication Manager selects an Invoke ID with the fixed value 1 each time a calling name is sent over the ISDN trunk group.

Long Holding Time (hours)

Available only if Automatic Circuit Assurance measurements are taken for the trunk group.

Valid Entry

Usage

0 to 10

The number of hours that the system considers a long holding time. A value of 0 indicates that the system does not support long holding calls.

Maintenance Tests

Enables or disables hourly maintenance tests on this trunk group.

Available only for aplt, isdn, sip, or tie trunk groups.

Outgoing ANI

The digit string sent in place of normal ANI. Overrides the normal ANI if this trunk group is used for an outgoing call with ANI. The ANI is sent exactly as administered, except for the normal truncation to seven digits for Russian ANI. This ANI override works both for calls originated in Communication Manager and calls tandemed through it. Accepts up to 15 digits.

Available only for CO, DIOD, FX, and WATS trunk groups.

Path Replacement Method

Available only if the Group Type is ISDN, the Supplementary Service Protocol is b or e, and Supplementary Services with Rerouting or DCS with Rerouting is enabled for the system. Unavailable if Path Replacement with Retention is enabled.

Valid Entry

Usage

always

Use any QSIG (SSB) trunk group as the replacement trunk group. A new call is always originated, even when the original trunk group is determined to be the replacement trunk group.

BR (better route)

Route pattern preferences help determine trunk group path replacement. The original trunk group is retained if Path Replacement with Retention is enabled. Path replacement fails (and the original trunk group is retained) if Path Replacement with Retention is disabled.

Path Replacement with Retention

Available only if the Group Type is ISDN, the Supplementary Service Protocol is b or e, and Supplementary Services with Rerouting or DCS with Rerouting is enabled for the system.

Replace Unavailable Numbers

If enabled, replaces unavailable numbers with administrable strings for incoming and outgoing calls assigned to the specified trunk group. Applies to BRI/PRI, H.323, and SIP trunks. Also applies to analog trunks if Analog Trunk Incoming Call ID is enabled for the system and Receive Analog Incoming Call ID for the trunk is set to any value except disabled.

Available only if the group type is isdn or sip.

Request Category

Indicates if Communication Manager should request a call category from the local telephone company central office (CO).

Available only if the Country code is 15 and MF shuttle signaling is enabled.

Replace Restricted Numbers

The Replace Restricted Numbers field indicates whether to replace restricted numbers with administrable strings for incoming and outgoing calls assigned to the specified trunk group. If the Replace Restricted Numbers field is enabled, Communication Manager replaces the display irrespective of the service type of the trunks such as BRI, PRI, H.323, and SIP trunks. The Replace Restricted Numbers field is available if the Group Type is ISDN or SIP.

Seize When Maintenance Busy

Indicates whether this server generates an outgoing seizure when a trunk in this trunk group is maintenance busied and whether the far-end server or switch is administered to do likewise. This supports the Electronic Tandem Network Busyout feature, which is intended to prevent a far-end server or switch from reporting problems with a trunk that has been removed from service. This field does not affect the behavior of the far-end server or switch. It controls the behavior of your server and defines the expected far-end behavior.

This field only affects ports on TN760C (or later release), TN767, and TN464C (or later release) circuit packs. For DIOD trunks using TN464F (or later release) or TN2464 circuit packs, available only for diod trunk groups when the Trunk Signaling Type is pulsed, cont, or dis.

Valid Entry

Usage

near-end

Communication Manager generates an outgoing seizure when a trunk is maintenance busied, but the far-end server or switch does not. The seizure is maintained until the maintenance busyout is released.

far-end

The far-end server or switch generates an outgoing seizure when a trunk is maintenance busied, but this server running Communication Manager does not.

both-ends

Both this server running Communication Manager and the far-end server or switch generate an outgoing seizure when a trunk is maintenance busied.

If a server generates an outgoing seizure when a trunk is busied out, the seizure will probably cause alarms at the far-end server or switch, perhaps leading to a far-end maintenance busy out, unless the far-end server or switch is administered to expect this behavior.

If the administered value of this field is either far-end or both-ends, any abnormally long incoming seizure (including failure to drop from a completed call) is the result of a far-end maintenance busy condition. This assumption might be incorrect, since the abnormally long seizure might actually be due to failure of the trunk circuit.

Send Called/Busy/Connected Number

Specifies if the dialed number, whether called (ringing), busy (busy tone), or connected (answered) is sent on incoming or tandemed ISDN calls.

Available only if QSIG Value-Added is enabled for the trunk group.

Valid Entry

Usage

y

The dialed number is sent on incoming or tandemed ISDN calls. This field must be enabled in order for the Calling Party Number of an incoming ISDN call to display at the transferred-to station after a QSIG transfer operation. If enabled, the Numbering - Public/Unknown Format is accessed to construct the actual number sent, or the Numbering - Private Format is used.

n

Disables the sending of the dialed number on incoming or tandemed ISDN calls.

r

Restricted. The connected number is sent presentation restricted.

Send Calling Number

Specifies whether the calling party’s number is sent on outgoing or tandemed ISDN calls.

Note:

The Numbering - Public/Unknown Format can override the Send Calling Number administration

Valid Entry

Usage

y

The calling party's number is sent on outgoing or tandemed ISDN calls. If enabled, the Numbering - Public/Unknown Format is accessed to construct the actual number sent, or the Numbering - Private Format is used.

n

Disables the sending of the calling party's number on outgoing or tandemed ISDN calls. If disabled, an incoming number is not tandemed out again. This applies to all Supplementary Service Protocols.

r

Restricted. The calling number is sent presentation restricted. If set to restricted, an incoming number is marked restricted when it is tandemed out again. This applies to all Supplementary Service Protocols.

Send Connected Number

Specifies if the connected party’s number is sent on incoming or tandemed ISDN calls.

Available only if QSIG Value-Added is disabled for the trunk group.

Valid Entry

Usage

y

The connected party's number is sent on outgoing or tandemed ISDN calls. If enabled, the Numbering - Public/Unknown Format is accessed to construct the actual number sent, or the Numbering - Private Format is used. This field must be enabled for the Calling Party Number of an incoming ISDN call to display at the transferred-to station after a QSIG transfer operation.

n

Disables the sending of the connected party's number on outgoing or tandemed ISDN calls. If disabled, an incoming number is not tandemed out again. This applies to all Supplementary Service Protocols.

r

Restricted. The connected number is sent presentation restricted. If this field is set to r, an incoming number is marked restricted when it is tandemed out again. This applies to all Supplementary Service Protocols.

Note:

The AT&T Switched Network Protocol does not support restricted displays of connected numbers. Therefore, if you administer the 1a country-protocol/ protocol-version combination for the media module, you should not administer the Send Connected Number as restricted, as this causes display problems. The Numbering - Public/Unknown Format overrides the Send Connected Number administration for any administrable block of extensions.

Send EMU Visitor CPN

Controls which calling party identification (extension of the primary telephone or extension of the visited telephone) is used when a call is made from a visited telephone. There are areas where public network trunks disallow a call if the calling party information is invalid. In this case, there can be instances where the extension of the primary telephone is invalid and the extension of the visited telephone must be used.

Valid Entry

Usage

y

Sends calling party identification information on the extension of the EMU user’s telephone.

n

Sends calling party identification information on the primary telephone.

Send Name

Specifies whether the calling, connected, called, or busy party’s administered name is sent to the network on outgoing or incoming calls. Available only for isdn or sip trunk groups.

Valid Entry

Usage

y

When the Supplementary Service Protocol is e (DCS with Rerouting), only values of y and n are permitted.

n

When the Supplementary Service Protocol is e (DCS with Rerouting), only values of y and n are permitted.

r (restricted)

The calling/connected name will be sent by Communication Manager, but will be marked presentation restricted. This value is valid only if the Supplementary Service Protocol is a (national supplementary service), b (for called/busy only), or d for the QSIG Global Networking Supplementary Service Protocol.

Note:

If name information is not administered for the calling station or the connected, called, or busy station; the system sends the extension number instead of the name.

Short Holding Threshold

Available only if Automatic Circuit Assurance measurements are taken for this trunk group.

Valid Entry

Usage

0 to 30

The number of times the system will record a short holding call before alerting an attendant to the possibility of a faulty trunk.

If 0 is entered, no short holding calls are recorded.

Short Holding Time (seconds)

Available only if Automatic Circuit Assurance measurements are taken for this trunk group.

Valid Entry

Usage

0 to 160

The length of time that the system considers as being a short holding time.

If 0 is entered, the system does not support short holding calls.

Show ANSWERED BY on Display

Available only for isdn pri/bri, isdn h.323, and sip trunk groups.

Valid Entry

Usage

y

The words ANSWERED BY display in addition to the connected telephone number on calls over this trunk. This is the default.

Note:

Based on display language settings for stations, ANSWERED BY is translated into and displayed in the appropriate language.

n

Only the connected telephone number displays. This might be preferred when outgoing calls are over a trunk that might be redirected.

Shuttle

Enables or disables MF shuttle signaling.

Available only for co, fx, or wats trunk groups, with a Country code of 15, when the Outgoing Dial Type is rotary.

Signaling Group

The signaling group number.

Start B Signal

Indicates which B-signal should be used to start a call. The value administered in this field must be coordinated with the local telephone company central office.

Available only when the Country code is 15 and MF shuttle signaling is enabled.

Valid Entry

Usage

2

Start calls with signal B2 (next digit).

3

Start calls with signal B3 (previous digit).

Start Position

Available only when the Country code is 15 and MF shuttle signaling is enabled.

Valid Entry

Usage

1 to 9

Indicates which digit in the digit string is the previously sent digit. The value administered in this field must be coordinated with the local telephone company central office.

Suppress # Outpulsing

Indicates whether or not to suppress the final # in cases where the system would normally outpulse it. Used if end-to-end signaling begins with (and includes) #. This field should be enabled when the local telephone company central office or any other facility treats # as an error.

Time (sec) to Drop Call on No Answer

Available only for co or diod trunk groups when the Outgoing Dial Type is mf, or for co, diod, fx, or wats trunk groups when the Country code is 15.

Valid Entry

Usage

0 to 1200

When forwarding the other data as MSI, Communication Manager forwards the ASAI user data in a non-shared codeset 0 UUI.

Voice Paging Timeout (sec)

Available only if the trunk is used only for paging.

Valid Entry

Usage

10 to 6000

The number of seconds before a paged trunk call drops. Default is 10.

Wideband Support

Note:

This feature is not supported on the DS1 interfaces on branch gateways (G700).

Enables or disables wideband switching on this trunk group.

Available only if Wideband Switching is enabled for the system.

Note:

Wideband trunk calls are treated as a single trunk call when Automatic Circuit Assurance (ACA) measurements are taken. This way, if an ACA referral call is generated (for short or long holding time), the wideband call only triggers a single referral call using the lowest B-channel trunk member associated with the wideband channel.
