If the system is to provide pseudo answer supervision, set an appropriate time for the time-out period via System Option 43 (Pseudo Answer SupervisionTimer =10 through 60 Seconds).Operation The following paragraphs describe the Trunk Hardware Options. Options are listed in alphabetic order. Calling Party Disconnect Timer: This defines how long the system will wait for . the far-end, a ground start trunk; to acknowledge a trunk release. Debounce Timer: This timer specifies the period for which an incoming sei- zure is to be debounced before being recognized as a valid incoming seizure.Dictation Trunk: If selected, this maintains trunk dialing for the duration of the call. See DICTATION TRUNK. Digit Outpulsing Ratio: This field specifies the break/make ratio during out- pulsing. It can be set to 60/40,66/33, or 30/20. Disconnect Timer: This defines the time a release signal must be continuously present before a call is disconnected. Note: For digital DID trunks, the range is150-300 ms. DTMF: DTMF, if selected, forces DTMF digits to be transmitted on the trunk when dialing. if not selected, digits are pulsed onto the trunk. E Lead Invert/M Lead Invert: These two fields provide the flexibility to specify the polarity of the E and M leads to match the far end connection. M Lead Invert must be enabled for type 5 operation. Far-End Gives Answer Supervision: If selected, answer signals are expected, and acted upon when received on the trunk; answer signals are not gener- ated internally. If not selected, answer signals received are ignored. Flash Timer: This defines the duration of a flash transmitted onto a trunk in a digital bay; for analog trunks it is 200 ms.105 3-98 9 10%0%-l OENAIssue 3Revision 1
System Features Guard Timer: This defines how long the system will wait after releasing the trunk before seizing it again for an outgoing call. Ignore Line Reversal During Seizure: If selected, line reversal is not recog- nized as an incoming seizure. Ignore Remote Disconnect: If selected, release signals from the far-end are ignored. If not selected, release signals cause disconnection of the call. Impedance: “600” should be selected if the trunk is to be connected to a carri- er facility, or the cable is short. This setting provides a 600 ohm + 2PF termi- nation impedance match for the incoming line. “Complex” should be se- lected if the trunk is to be connected directly to cable facilities. This setting provides the standard AT&T complex balance network as a termination im- pedance for the incoming line. Incoming start type: This field specifies the incoming type of the trunk, which can be set to immediate incoming, wink start incoming, or delay dial incom- ing. Inhibit Automatic Supervision: If selected, the system waits for the far-end to provide answer supervision before providing answer supervision to an incom- ing Tie or DID trunk. Is this a CO?: Select if trunk is to terminate at the Central Office. If NO, a 2dB pad is added in the circuit. Refer to Practice 9109-095-180, Engineering In-formation. Interdigit Timer: This defines the time gap inserted between outpulsed digits. Loop Start or Ground Start: This defines trunk signaling type (Tl only). No Release Alarm: If selected, a trunkfailing to release is removed from ser- vice and maintenance is notified. The trunk can only be returned to service manually. If not selected, the trunk remains in service. No Seize Alarm: If selected, a trunk failing to return a seize acknowledge- ment on three successive occasions is removed from service; maintenance is not notified. If not selected, the trunk remains in service. If the trunk origi- nates, the no seize count is reset. As well, if the trunk had been removed from service due to a no seize count, the trunk is returned to service and the incom- ing call on the trunk is processed. Outgoing Start Type: This field specifies the outgoing type of the trunk, which can be set to immediate outgoing, wink start outgoing, delay dial out- going or delay dial with integrity. Outpulse Delay Timer: This timer specifies the pause between seizing and the start of dialing, applicable to immediate outgoing trunks only. This value should be specified after determining the far end characteristics. Post Call Metering: This defines how long the system will wait for and record meter pulses after the release signal is received. Release Acknowledge timer: This specifies the time-out period to wait for a release acknowledge signal from the far end.9 109-094-l OENA Issue 3Revision 1105 3-99
Features Description Remote End is a Satellite: Select if the trunk is to terminate at a satellitePABX. Refer to Practice 9109-094-180-NA, Engineering Information for de- tails of loss/gain. Remote End is a Satellite with OPS lines: Select if the trunk is to terminate at a satellite PABX with OPS lines. Refer to Practice 9109-094-l80-NA, Engineer- ing Information for details of loss/gain. Reverse to Idle: In some central offices, upon seizure, the CO reverses the po- larity on the trunk. When the call ends, the CO again reverses the polarity, returning the trunk to its normal idle state. When the Reverse to Idle option is enabled, the PABX treats the reversal to idle condition as a disconnect signal from the CO. The Far-End Gives Answer Supervision option has no effect. Ring Cycle Timer: This defines a period during which a minimum ring burst (250 ms) must be present before the system will recognize it as an incoming call. Ringing Debounce Timer: This defines the duration during which the system tries to detect the minimum ring burst, indicating the persistence of an in- coming call. Ringing Expected: If selected, incoming calls are not reported unless ringing is recognized. If other seize signals are received before ringing, the trunk isbusied-out for outgoing calls, but the incoming call is not reported until ringing is received. Seize Timer: This defines the time the system will wait for a seize acknowl- edge from a ground start trunk. Also see Option “No Seize Alarm” in this list. Toil Office: Select if the CO trunk is to be connected to a Toll Office. This op- tion is applicable to systems using the North American loss plan. It provides a3 dB loss for trunk-to-OPS line connections, and a 6 dB loss for trunk-to-ONS line connections. If not selected, “normal” through switch loss is provided. Refer to Practice 9109-094-180-NA, Engineering Information. Wait For Delay Timer: This timer specifies the period to wait for the delaysig- nal from the far end. It is only applicable if the trunk is of type delay dial out-going (without integrity). Wink Timer: This timer specifies the duration of the wink signal sent to the far end if the trunk is programmed as a Wink Start Incoming or Delay Start in- coming. Trunk Dial Tone DetectionDescription 3.108After a trunk has been accessed, the system tries to detect dial tone onthe trunk. If dial tone is detected before time-out, the system begins sending digits. Should no dial tone be present after the time-out period, if limited wait is specified, the system automatically begins sending digits. Otherwise it removes the trunk from service and raises an alarm.105 3-100 9 109-094-l OS-NAIssue 3Revision 1
System Features Dial tone detection, without the alarm, can also occur in the middle of trunk dialing; see AUTOMATIC ROUTE SELECTION.Conditions The following conditions apply to this feature: lEnabling Limited Wait For Dial Tone disables the No Dial Tone Alarm. lThe no dial tone alarm time is set at 10 seconds. lWhen the trunk is removed from service, the party dialing on the trunk -ends dialing and is given busy tone. l50 simultaneous dial tone detections can occur in the system at any one- time. lIf dial tone detection resources are not available and the alarm is enabled then the trunk is removed from service. If the alarm is not enabled then dial tone is assumed to have been supplied and dialing commences after a short pause. ProgrammingSet System Option 48 (Limited Wait for Dial Tone) for l-l 5 seconds. To program a trunk to wait the limited time for dial tone, select COS Option 802 (Limited Wait for Dial Tone) for the trunk. To enable the no dial tone alarm for a trunk, enable COS Option 805 (Trunk No Dial Tone Alarm). OperationNoneI Trunk GroupsDescription 3.109 Trunk groups are defined and used in the ARS forms in CDE to control extension access to trunks, to define trunk options, and to apply features totrunk groups, For further information, refer to Practice 9109-094-220-NA, Automatic Route Selection and Toll Control, and to Practice 9109-094-210-NA, Customer Data Entry (CDE).ConditionsThe following conditions apply to this feature: lSMDR is applied to trunks on a per trunk group basis; refer to Practice 9109-094-221-NA, Station Message Detail Recording. l A maximum of 50 individual trunk groups are available. lA maximum of 50 trunks are permitted in an individual trunk group. lA trunk may be a member of only one trunk group. lIndividual trunks must be programmed before they are entered into trunk groups.
Features Description lDirect Trunk Select and Private Trunk line trunks must be in trunk groups before outgoing calls can be made on the trunk lines. lDirect Trunk Select and Private Trunk Line trunks are never hunted from atrunk group. lA trunk is selected from a trunk group if it is idle, if it is not being seized by another party, if a no seize alarm is not pending and if the caller and the trunk can connect together. lA trunk does not need to be in a trunk group to originate a call. lTrunk groups can have circular or terminal hunting. ProgrammingProgram trunks into Trunk Groups via CDE Form 16 (Trunk Groups). Each trunk group may also be given a unique name via CDE Form 16 (Trunk Groups). Refer to Practice 9109-094-220-NA, Automatic Route Selection.Operation None Ttynk Operation -Direct Inward Dial (DID) Description3.110 The DID trunk type is one of the four trunk types, independent of the hardware actually used to support the types, used in the system. DID trunks allow incoming trunk calls (DID) to reach extensions directly, with- out Attendant intervention or assistance. The length of the incoming num- ber, the number of digits to be absorbed, and a prefix digit, if required, may also be specified. Calls coming into the PABX on DID type trunks are assumed to be callers from outside the company, similar to CO trunk type calls. The callers therefore re- ceive different call progress tones and are handled differently than Tie and DISA trunk type calls, which are assumed to be internal calls. For the hardware that supports the DID trunk type operation, see TRUNK SUP-PORT-DIRECTINWARD DlAL(DID),TRUNKSUPPORT-Tl,and TRUNKSUP- PORT -E&M. Also see DID/DIAL-IN/Tie INTERCEPTS. ConditionsThe following conditions apply to this feature: eIf the DID trunk sends less digits than expected, the trunk receives reordertone from the PABX system after the inter digit time-out (15 s). 0DID trunks can dial any access code for any type of device.105 3-1029109-094-l 05-NA Issue 3Revision 1
