DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 969 Trunk Group 17 Group Type Enter the type of trunk group. Valid entries Usage Access Use access trunks to connect satellite switches to the main switch in Electronic Tandem Networks (ETN). Access trunks do not carry traveling class marks (TCM) and thus allow satellite callers unrestricted access to out-dial trunks on the main switch. Allows Inband ANI. APLT Advanced Private Line Termination (APLT) trunks are used in private networks. APLT trunks allow inband ANI. CAMACAMA trunks route emergency calls to the local community’s Enhanced 911 systems. CO CO trunks typically connect your switch to the local central office, but they can also connect adjuncts such as external paging systems and data modules. CPE Use CPE trunks to connect adjuncts, such as paging systems and announcement or music sources, to the switch. DID Use DID trunks when you want people calling your organization to dial individual users directly without going through an attendant or some other central point. Allows Inband ANI. DIOD DIOD trunks are two-way trunks that transmit dialed digits in both directions. In North America, use tie trunks for applications that require two-way transmission of dialed digits. Allows Inband ANI. DMI-BOS Digital Multiplexed Interface – Bit-Oriented Signaling (DMI-BOS) trunks allow communication with systems using DMI-BOS protocol. DMI-BOS trunks allow inband ANI. FX An FX trunk is essentially a CO trunk that connects your switch directly to a central office outside your local exchange area. Use FX trunks to reduce long distance charges if your organization averages a high volume of long-distance calls to a specific area code.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 970 Trunk Group 17 ISDN Use ISDN trunks when you need digital trunks that can integrate voice, data, and video signals and provide the bandwidth needed for applications such as high-speed data transfer and video conferencing. ISDN trunks can also efficiently combine multiple services on one trunk group. You cannot enter isdn unless the ISDN-PRI field, the ISDN-BRI Trunks field, or both have been enabled on the System-Parameters Customer-Options screen. RLT Release Link trunks work with Centralized Attendant Service in a private network. Tandem Tandem trunks connect tandem nodes in a private network. Tandem trunks allow inband ANI. Tie Use tie trunks to connect a switch to a central office or to another switch in a private network. Tie trunks transmit dialed digits with both outgoing and incoming calls, and allow inband ANI. WATS Use WATS trunks to reduce long-distance bills when your organization regularly places many calls to a specific geographical area in North America. Outgoing WATS service allows calls to certain areas (“WATS bands”) for a flat monthly charge. Incoming WATS trunks allow you to offer toll-free calling to customers and employees. Valid entries Usage
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 971 Trunk Group 17 CDR Reports NOTE: For ISDN trunk groups, the Charge Advice field affects CDR information. For CO, DIOD, FX, and WATS trunk groups, the Analog PPM field affects CDR information. Group Name COR Valid entries Usage y All outgoing calls on this trunk group will generate call detail records. If the Record Outgoing Calls Only field on the CDR System Parameters screen is n, then incoming calls on this trunk group will also generate call detail records. n Calls over this trunk group will not generate call detail records. r (ring-intvl) CDR records will be generated for both incoming and outgoing calls. In addition, the following ringing interval CDR records are generated: nAbandoned calls: The system creates a record with a condition code of “H,” indicating the time until the call was abandoned. nAnswered calls: The system creates a record with a condition code of “G,” indicating the interval from start of ring to answer. nCalls to busy stations: The system creates a record with a condition code of “I,” indicating a recorded interval of 0. Valid entries Usage 1 to 27 characters Enter a unique name that provides information about the trunk group. Don’t use the default entry or the group type (DID, WATS) here. For example, you might use names that identify the vendor and function of the trunk group: USWest Local; Sprint Toll, etc. Valid entries Usage 0 to 95 Enter a class of restriction (COR). Classes of restriction control access to trunk groups, including trunk-to-trunk transfers.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 972 Trunk Group 17 Tip: Remember that facility restriction levels (FRL) are assigned to classes of restriction. Even if 2 trunk groups have classes of restriction that allow a connection, different facility restriction levels may prevent operations such as off-net call forwarding or outgoing calls by remote access users. TN Tip: Double-check your entry. If you accidentally enter an unassigned tenant partition number, the system will accept the entry but no calls will go to the trunk group. TA C Enter the trunk access code (TAC) that must be dialed to access the trunk group. A different TAC must be assigned to each trunk group. CDR reports use the TAC to identify each trunk group. CO Type This field appears when the Country field is 14 and is used only by trunk group members administered on a TN464D vintage 2 or later DS1 circuit pack. Valid entries Usage 1 to 20 (G3si/csi)Enter a Tenant Partition number to assign this trunk group to the partition. 1 to 100 (G3r) Valid entries Usage 1-4 digit numberEnter any number that fits the format for trunk access codes or dial access codes defined in your dial plan. *, #* and # may be used as the first character in a TAC. Valid entries Usage analog This field specifies whether the trunk group is connected to analog or digital facilities at the central office. digital
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 973 Trunk Group 17 Protocol Type This field specifies the type of line signaling protocol used for DID and DIOD trunk groups. This field appears when the Country field is 15 and is used only by trunk group members administered on a TN2199 or TN464D vintage 3 or later circuit pack. Direction This field appears for all trunk groups except DID and CPE. Outgoing Display This field allows display phones to show the name and number of the trunk group used for an outgoing call before the call is connected. This information may be useful to you when you’re trying to diagnose trunking problems. CESID I Digits Sent For emergency 911 service, your switch may send Caller’s Emergency Service Identification (CESID) information to the central office or E911 tandem switch. This digit string is part of the E911 signaling protocol. This field appears when Group Type is cama. Valid entries Usage inloc (Incoming local) Enter the protocol the central office is using for this trunk group. Only the inloc protocol provides ANI. intol (Incoming toll) Valid entries Usage incoming Enter the direction of the traffic on this trunk group. The entry in this field affects which timers appear on the Administrable Timers page. outgoing two-way Valid entries Usage y Displays the trunk group name and number. n Displays the digits the caller dials. Valid entries Usage 1 to 3 digits Determine the correct entry for this field by talking to your E911 provider.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 974 Trunk Group 17 Trunk Signaling Type This field controls the signaling used by members in private network trunk groups, mainly in Italy, Brazil, and Hungary. This field appears if the Group Type is access, aplt, diod, rlt, tandem, or tie. Entries in this field affect which timers appear on the Administrable Timers page. Valid entries Usage cont (continuous)E&M trunks in Italy, Brazil, and Hungary can use either continuous or discontinuous signaling. Each entry specifies a set of signals and available timers used in the process of setting up and releasing connections. The type of signaling you select on your switch must match the signaling type administered on the far-end switch. Use these values only when all trunk group members are assigned to ports on a TN464F, TN2464, or TN2140 circuit pack. Entering one of these values causes the Send Release Ack, Receive Release Ack, and Send Answer Supervision fields to appear. Refer to ‘‘ Trunk Type (in/out)’’ on page 984 for more information. dis (discontinuous) blank If this field is blank, ports from any other tie trunk circuit pack may be added as trunk group members. Use the following entries for tie trunks in Main-Satellite/Tributary networks. Each entry defines a function of the trunk group in the network. Use these values only when all trunk group members are assigned to a TN497 circuit pack. tgu (for outgoing trunks)Enter tgu at the main switch to administer a tie trunk group connected to a satellite switch. (This same group should be administered as tge at the satellite.) tge (for incoming trunks)Enter tge at a satellite switch to administer a tie trunk group connected to the main switch. (This same group should be administered as tgu at the main switch.) tgi (for internal trunks)Enter tgi at to administer a two-way tie trunk group between 2 satellites or between the main switch and a satellite. (This trunk group should be administered as tgi on both switches.)
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 975 Trunk Group 17 Dial Access This field controls whether users can route outgoing calls through an outgoing or two-way trunk group by dialing its trunk access code. Allowing dial access does not interfere with the operation of AAR/ARS. !SECURITY ALERT: Calls dialed with a trunk access code over WATS trunks bypass AAR/ARS and aren’t restricted by facility restriction levels. For security, you may want to leave the field set to n unless you need dial access to test the trunk group. This field also controls the signaling used by members in public network digital trunk groups. This field displays if the Group Type field is access, aplt, rlt, tandem, or tie. Entries in this field affect which timers appear on the Administrable Timers page. DIOD trunks support pulsed and continuous E&M signaling in Brazil and discontinuous E&M signaling in Hungary. Refer to DEFINITY ECS Application Notes for Type Approval for more information. Use the following entries for DIOD trunks. Use these values only when all trunk group members are assigned to a TN464F (or later version) or TN2464 circuit pack. pulsed cont discont blank Brazil E&M trunks can use continuous and pulsed E&M. For continuous E&M signaling, set this field to cont. For pulsed E&M signaling, set this field to pulsed. A blank setting provides R2 signaling. Hungary uses discontinuous E&M signaling when this field is dis. Valid entries Usage y Allows users to access the trunk group by dialing its access code. n Does not allow users to access the trunk group by dialing its access code. Attendants can still select this trunk group with a Trunk Group Select button. Valid entries Usage
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 976 Trunk Group 17 Busy Threshold Use this field if you want attendants to control access to outgoing and two-way trunk groups during periods of high use. When the threshold is reached and the warning lamp for that trunk group lights, the attendant can activate trunk group control: internal callers who dial out using a trunk access code will be connected to the attendant, and the attendant can prioritize outgoing calls for the last remaining trunks. Calls handled by AAR and ARS route patterns go out normally. Night Service This field sets the destination to which incoming calls go when Night Service is in operation. If a Night field on the Group Member Assignments page is administered with a different destination, that entry will override the group destination for that trunk. CPE, DID, and DIOD trunk groups do not support night service. Tip: Whenever possible, use a night service destination on your switch: otherwise some features won’t work correctly, even over a DCS network. Queue Length Outgoing calls can wait in a queue, in the order in which they were made, when all trunks in a trunk group are busy. If you enter 0, callers receive a busy signal when no trunks are available. If you enter a higher number, a caller hears confirmation tone when no trunk is available for the outgoing call. The caller can then hang up and wait: when a trunk becomes available, the switch will call the extension that Valid entries Usage 1 to 99 ( G3si/csi)Enter the number of trunks that must be busy in order to light the warning lamp on the Attendant Console. For example, if there are 30 trunks in the group and you want to alert the attendant whenever 25 or more are in use, enter 25.1 to 255 (G3r) Valid entries Usage blank Leave this field blank if the Trunk Type (in/out) field is not auto/…. An extension number (can be a VDN)Enter the extension of your night service destination. attdCalls go to the attendant and are recorded as Listed Directory Number (LDN) calls on call detail records.
