DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 997 Trunk Group 17 Incoming Rotary Timeout (sec) Call setup at central offices that still use older switching equipment, such as step-by-step technology, is considerably longer then at central offices with more modern switches. If you’re receiving digits with incoming calls from a central office that uses less efficient switching technology, your switch needs to allow more time to ensure it receives all the incoming digits. When the Incoming Dial Type field is rotary, use this field to set the maximum time your switch will wait to receive all incoming digits from the far-end switch. Outgoing Dial Type This field sets the method used to transmit digits for an outgoing call. Usually, you should match what your central office provides. Refer to ‘‘ Types of address transmission’’ on page 1584 for more information. This field appears for Access, APLT, CO, DIOD, DMI-BOS, FX, RLT, and WATS trunk groups. It also appears for Tie trunk groups when the Trunk Signaling Type field is blank, cont, or dis. 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. Valid entries Usage 5 to 99If the system is connected to a step-by-step central office, or any CO using older switching technology, enter at least 18 seconds; if not, enter at least 5 seconds. Valid entries Usage tone Enter tone to use Dual Tone Multifrequency (DTMF) addressing, also known as “touch tone” in the U.S. Entering tone actually allows the trunk group to support both DTMF and rotary signals. For pulsed and continuous E&M signaling in Brazil and for discontinuous E&M signaling in Hungary, use tone or mf. rotaryEnter rotary if you only want to allow the dial pulse addressing method used by non-touch tone phones. If you have a full touch tone system internally and a connection to a central office that only supports rotary dialing, for example, it would be appropriate to enter rotary.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 998 Trunk Group 17 Cut-Through This field appears when the Outgoing Dial Type field is either rotary or tone. !SECURITY ALERT: Entering y in this field will reduce your ability to prevent toll fraud. mfEnter mf if the Trunk Signaling Type field is blank. The Multifrequency Signaling field must be enabled on the System-Parameters Customer-Options screen in order for you to enter mf here. You may not enter mf if the Used for DCS field (Field descriptions for page 2) is y. For pulsed and continuous E&M signaling in Brazil and for discontinuous E&M signaling in Hungary, use tone or mf. automaticEnter automatic for tie trunks if the Trunk Signaling Type field is blank. This provides “cut-through” operation to outgoing callers who dial a trunk access code, connecting them directly to central office dial tone and bypassing any toll restrictions administered on your switch. r1mfCAMA trunk groups use r1mf. It is the only outgoing dial type allowed on CAMA trunk groups. Valid entries Usage y Enter y to allow users to get dial tone directly from the central office. Outgoing calls over this trunk group will bypass AAR/ARS (if you’re using it) and any of your administered restrictions (such as COR or FRL). n Enter n and the user will receive switch dial tone. Instead of digits being sent to the central office, they will be collected and checked against administered restrictions. If no restrictions apply, the digits are sent to the central office. Valid entries Usage
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 999 Trunk Group 17 Incoming Dial Type Indicates the type of pulses required on an incoming trunk group. Usually, you should match what your central office provides. Refer to ‘‘ Types of address transmission’’ on page 1584 for more information. This field appears for Access, APLT, DID, DIOD, DMI-BOS, FX, RLT, Tandem, and WATS trunk groups. It also appears for Tie trunk groups when the Trunk Signaling Type field is blank, cont, or dis. NOTE: The value in this field affects the appearance of the Incoming Partial Dial (sec) field on the Administrable Timer Page. Wink Timer (msec) This field allows you to reduce the risk of glare by controlling part of call setup. Requirements for the United States domestic network specify that the wink signal for wink-start trunks must begin within 5 seconds after a trunk is seized. For trunks with a delay-dial start, the wink must not last longer than 5 seconds. While some circuit packs are hard-coded to allow the full 5 seconds in both cases, other circuit packs allow you reduce the allowed start time and duration, thus reducing the window in which glare could occur. Valid entries Usage tone Enter tone to use Dual Tone Multifrequency (DTMF) addressing, also known as “touch tone” in the U.S. Entering tone actually allows the trunk group to support both DTMF and rotary signals. Also, if you’re using the Inband ANI feature, enter tone. For pulsed and continuous E&M signaling in Brazil and for discontinuous E&M signaling in Hungary, use tone. rotaryEnter rotary if you only want to allow the dial pulse addressing method used by non-touch tone phones. Though the tone entry supports rotary dialing as well, it’s inefficient to reserve touch tone registers for calls that don’t use DTMF. mfEnter mf if the Trunk Signaling Type field is blank. The Multifrequency Signaling field must be enabled on the System-Parameters Customer-Options screen in order for you to enter mf here. You may not enter mf if the Used for DCS field (Field descriptions for page 2) is y. For pulsed and continuous E&M signaling in Brazil and for discontinuous E&M signaling in Hungary, use mf.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 1000 Trunk Group 17 Unlike other fields on this screen, the Wink Timer field therefore controls 2 different variables. What your entry does depends on the outgoing value in the Trunk Type (in/out) field. . This field appears when the “out” side of the entry in the Trunk Type (in/out) field is …/wink or …/delay and the Group Type is tie, access, aplt, dmi-bos, rlt, or tandem. The setting in this field only affects trunks administered to ports on TN760C (vintage 4 or later), TN767, TN464C (or later), and TN2242 circuit packs. If the trunk group also contains trunks assigned to ports on other types of circuit packs, those trunks are unaffected. Trunk Termination This field adjusts the impedance of the trunk group for optimal transmission quality. Check with your service provider if you’re not sure of the distance to your central office. Setting of the Trunk Type (in/out) field What the Wink Timer field sets …/wink Maximum duration of the wink signal (wait-for-wink-to-end) …/delayMaximum interval after trunk seizure for the wink to begin (wait-for-wink-to-start) Valid entries Usage 300 to 5000 in increments of 50In general, Lucent recommends that you not change this field. If you do, remember that your switch’s timing must be compatible with the timing on the far-end switch. Valid entries Usage 600ohm Enter 600ohm when the distance to the central office or the switch at the other end of the trunk is less than 3,000 feet. rc Enter rc when the distance to the central office or the switch at the other end of the trunk is more than 3,000 feet.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 1001 Trunk Group 17 Disconnect Timing (msec) This field specifies the minimum time in milliseconds that the central office or far-end switch requires to recognize that your switch has disconnected from a call. This timer does not affect ports on a circuit pack that uses the administrable Incoming Disconnect and Outgoing Disconnect timers; in fact, settings on those two timers override this field. End-to-End Signaling Auxiliary equipment such as paging equipment and music sources may be connected to DEFINITY ECS by auxiliary trunks. The switch may send DTMF signals (touch tones) to these devices. This field, which appears for CPE (customer-provided equipment) trunk groups, sets the duration of these tones. NOTE: For trunks that do not receive real answer supervision, a “connect” Event report is sent when the Answer Supervision Timeout occurs. Analog Gain Use this field to reduce the strength of incoming signals on TN2199 ports if users regularly experience echo, distortion, or unpleasantly loud volume. Experiment to find the best setting for your situation. This field appears if the Country field is 15 and the Trunk Type (in/out) field is 2-wire-ac, 2-wire-dc, or 3-wire. Valid entries Usage 140 to 2550 ms in increments of 10The default of 500 is an industry standard and you shouldn’t change it. If you set this field too high, your switch won’t disconnect sometimes when it should; too low, and it will disconnect when it shouldn’t. Valid entries Usage 60 to 360 ms in increments of 10Use this field to set the duration in milliseconds of the touch-tone signal that is sent to the connected equipment. Valid entries Usage a Reduces the incoming signal by -3dB. b Reduces the incoming signal by -6dB. c Reduces the incoming signal by -8dB. none No reduction. Don’t change this setting unless the trunk group’s sound quality is unacceptable.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 1002 Trunk Group 17 Digit Treatment Use this field to modify an incoming digit string (as on DID and tie trunks, for example) by adding or deleting digits. You’ll need to do this if the number of digits you receive doesn’t match your dial plan. If you enter absorption or insertion, then you must enter a value in the Digits field. NOTE: In a DCS network, DCS features that use the remote-tgs button (on phones at a remote switch) do not work when the incoming trunk group at your switch deletes or inserts digits on incoming calls. The remote-tgs button on a remote switch, for example, tries to dial a TAC on your switch. If your switch adds or deletes digits, it defeats this operation. If you need to manipulate digits in a DCS network (for example, to insert an AAR feature access code), do it on the outgoing side based on the routing pattern. Digits This field is used with the Digit Treatment field, and its meaning depends on the entry in that field. If the Digit Treatment field is absorption, this field specifies how many digits are deleted. If the Digit Treatment field is insertion, this field identifies the specific digits that are added. Valid entries Usage blank The incoming digit string is not changed. absorptionDeletes digits, starting at the beginning of the string. insertionAdds digits, starting at the beginning of the string. Valid entries Usage 1 to 5 Enter the number of digits to be deleted (absorbed). Up to 4 digits, including * and #Enter the actual digits to be added (inserted). blank This field can be blank only if the Digit Treatment field is blank.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 1003 Trunk Group 17 Expected Digits NOTE: Set this field to blank if the Digit Treatment field is set to insert and the Digits field contains a feature access code (for example, AAR or ARS) followed by digits. In this case, the number of digits expected are set on the AAR and ARS Digit Analysis Table and AAR and ARS Digit Conversion Table. Auto Guard This field controls ports only on TN438B, TN465B, and TN2147 circuit packs. TN438B ports have hardware support for detecting a defective trunk. TN465B and TN2147 ports consider a trunk defective if no dial tone is detected on an outgoing call, and the Outpulse Without Tone field is n on the Feature-Related System Parameters screen. Call Still Held This field is used when the receiving switch initiates the disconnection of incoming calls. It effectively extends the Incoming Glare Guard timer by 140 seconds. This field affects only TN438B, TN465B, and TN2147 ports and is used primarily when the Country Code field is 2. Valid entries Usage 1 to 18Enter the number of digits that the far-end switch sends for an incoming connection. If your switch is absorbing digits on this trunk group, the entry in this field must be larger than the entry in the Digits field. blank If you leave this field blank, you cannot administer digit absorption. Valid entries Usage y/n Enter y to prevent repeated seizures of a defective trunk. The switch will do a maintenance busy-out on these trunks. Valid entries Usage y/n Enter y to prevent glare by delaying an outgoing seizure of a trunk for at least 140 seconds after it is released from an incoming call.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 1004 Trunk Group 17 Sig Bit Inversion When transmission facilities use bit-oriented signaling (such as CAS), 2 bits are used to transmit seizure and release signals for calls. Called the A-bit and the B-bit, their meaning can vary. For example, in the A-bit a “1” might mean on-hook and a “0” might mean off-hook. The entry in the Country Protocol field on the DS1 Circuit Pack screen sets the default meaning of these bits. For trunk ports on TN2242 and TN464B and later circuit packs, this field allows you to invert the A- and B-bits as necessary so that the far-end switch can understand your switch’s seizure and release signals. If the far-end switch, such as a central office, on this trunk group interprets the A- and B-bits differently from the default, you may need to invert one or both bits — to change “1” to “0” and vice-versa in the A-bit, for example. Analog Loss Group This field determines which administered 2-party row in the loss plan applies to this trunk group if the call is carried over an analog signaling port in the trunk group. Digital Loss Group This field determines which administered 2-party row in the loss plan applies to this trunk group if the call is carried over a digital signaling port in the trunk group. Valid entries Usage A For the TN464B and later circuit packs, indicate which bits, if any, should be inverted. B A&B none A and none For the Japanese 2Mbit trunk circuit pack, indicate which bits, if any, should be inverted. Valid entries Usage 1 to 17Shows the index into the loss plan and tone plan. Valid entries Usage 1 to 17Shows the index into the loss plan and tone plan.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 1005 Trunk Group 17 Incoming Dial Tone Indicates whether or not your switch will give dial tone in response to far-end seizures of the trunk group. Line Length This field appears only when the Group Type field is tie and the Trunk Signaling Type field is tge, tgi, or tgu. NOTE: Unless one or more trunk members are administered, the administered value is not saved when you submit the screen (press ENTER). Send Release Ack This field appears when the Trunk Signaling Type field is cont or dis and only applies to TN2140 ports (used for Italian and Hungarian tie trunks). Receive Release Ack This field appears when the Trunk Signaling Type field is cont or dis and only applies to TN2140 ports (used for Italian and Hungarian tie trunks). Valid entries Usage y Enter y if the incoming trunk group transmits digits. For example, you would enter y for two-way, dial-repeating tie trunks that users select by dialing a trunk access code. nEnter n for trunks that aren’t sending digits, such as tandem or incoming CO trunks. Valid entries Usage short long Valid entries Usage y/n Enter y to send a release acknowledgment in response to a forward or backward release signal. Valid entries Usage y/n Enter y if the switch will receive a release acknowledgment in response to a forward or backward release signal.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 1006 Trunk Group 17 Dial Detection Applies only to TN2199 ports. The Country field must be 15. Extended Loop Range This field appears only for a DID trunk group and is used only with the TN459A circuit pack. Enter y or n depending on the distance between the central office and the switch. If greater than the required distance, then the field should be y. Trunk Gain This field specifies the amplification applied to the trunks in this group. With the values of the Trunk Termination and Country fields, the value in this field also determines the input and trans-hybrid balance impedance for TN465B, TN2146, TN2147, and TN2184 ports. All other CO and DID circuit packs are set automatically to high Drop Treatment This field only applies to DID trunks. It determines what the calling party hears when the called party terminates an incoming call. NOTE: In Italy, the Drop Treatment field must be administered as intercept for all DID trunk groups. Valid entries Usage A-wire B-wire Valid entries Usage y/n Valid entries Usage high Enter high if users complain of low volume. lowEnter low if users complain of squeal or feedback. Valid entries Usage intercept Select one. For security reasons, it’s better to apply a tone: silence could provide an opening for hackers. busy silence
