7-144ADMINISTRATION OPTIONS AND REQUIREMENTS — SYSTEM 75 R1V5 & GENERIC 1 Trunk Group — ISDN-PRI Trunk Applications ISDN-PRI trunk groups are defined by using the first page of the TRUNK GROUP screen. Since ISDN-PRI uses Message Oriented Signaling, the format of this screen is somewhat different from the assigned basic DS1 service. Page 2 administers certain features that are unique to ISDN-PRI trunk groups. Screen pages 3 and 4 are only displayed if the Service Type field on page 1 is administered CBC. Screen pages 5 through 11 are½ used as required to assign group members. Figure 7-79, Trunk Group Screen, Page 1 (ISDN-PRI), depicts this procedure.½ ½ TRUNK GROUPPage 1 of 11 Group Number: Group Type:—isdn-priSMDR Reports? y Group Name:OUTSIDE CALLCOR: 1TAC:Direction: two-wayOutgoing Display? n Dial Access: yBusy Threshold: 99Night Service: Queue Length: 0 Service Type: cbcAuth Code? n Usage Allot? yFar End Test No: TRUNK PARAMETERS Send Display/TCM in codeset 6/7: 6 Max Message Size to Send: 260 Connected to Toll? nSTT Loss: normalDTT to DCO Loss: normal Bit Rate: 1200Synchronization: asyncDuplex: full Figure 7-79.

Group TypeFor ISDN-PRI service applications this field should be translated isdn-pri. NOTE: The SYSTEM-PARAMETERS CUSTOMER-OPTION screen must have ISDN-PRI service enabled before this trunk group type can be translated. Dial AccessNormally, this field is defined as y. However, for some public network connections (such as service type CBC, MEGACOM, etc.), this field is defined as n. ADDENDUM 1 (December 1990) to 555-025-101, Issue 4
ADMINISTRATION OPTIONS AND REQUIREMENTS — SYSTEM 75 R1V5 & GENERIC 17-145 Night Service Service Type Usage Allot Far End Test No½ ½ Send Display/TCM in Codeset 6/7 If administered, then the extension number translated will receive all incoming calls (for the particular trunk group) when the switch is placed in night service mode. NOTE: Page 2 of the TRUNK GROUP screen permits an override entry for each particular type of ISDN network service. Also, trunk member night service is allowed. Assigns the service application for the ISDN-PRI trunk group. Since CBC permits reduced costs (depending on tariff and application), an improved grade-of-service, and customer premis control of networking, the option cbc should be considered for public network applications. Other options include any of the predefined or additional Services/Features listed in the Name field of the NETWORK-FACILITIES screen. Also, the options access, tie, and tandem are permitted. Field encodes and their descriptions are: y Enable usage allocation for those services provided by the trunk group. Used to maximize customer control of the allocation of CBC trunk group members to services (such as preventing a service from monopolizing the member of a group). NOTE: This option permits up to three usage allocation plans to be defined for the identified trunk group. The term usage allocation is the ability to set both a minimum and maximum number of trunk members that an ISDN Service/Feature may use at a given time. Each usage allocation plan can set limits for up to 10 services/features. n Disable usage allocation for the trunk group (default). This option places restrictions on either the Services/Features that can be carried on the trunk group or the number of calls that any one Service/Feature can have at any given time. This is the ISDN-PRI test line associated with the far-end’s test equipment and is reserved exclusively for maintenance testing. The test number should be assigned for both private and public networks. There is one test number per trunk group. As a part of the installation and ISDN-PRI service provisioning process, the test number must be coordinated with the terminating switch. NOTE: This field is equivalent to translating procedure 108, word 1, for Generic 2. This field maps the display information (codepoint 8) and the TCM information (codepoint 40) to codeset 6 or codeset 7, depending on whether a 6 or a 7 is translated. The distant switch will determine which should be translated. Specifically, if the distant switch is a 4ESS with 4e11 or 4e12 software, or a System 85 R2V4, then this field should be translated with a 7. If the distant switch is a 4ESS with 4e13, Generic 1, or Generic 2, then the field should be translated with a six. NOTE: For tandem node configurations, Generic 1 rebuilds the message in conformance to the outgoing trunk group. If any codeset/codepoint conversions are required, then the two endpoints must coordinate the conversions. Generic 1 can receive in either codeset (this is a send option).½ ½ ½ ½ ADDENDUM 1 (December 1990) to 555-025-101, Issue 4
7-146ADMINISTRATION OPTIONS AND REQUIREMENTS — SYSTEM 75 R1V5 & GENERIC 1 MaxThis field determines the maximum number of bytes that may be transmitted before an Message Sizeacknowledge reply is required. Permitted entries are 128, 244, 256, and 260 (default). to SendThis field must be administered to be the maximum size messages that the far end is able to receive and process. If the distant switch is another Generic 1, then any entry will work. Currently, System 85 R2V4, Generic 2, all releases of 4ESS, and 5ESS only support 128.½ The fields on page 2 of the TRUNK GROUP screen comprise an incoming call handling table. The table consists of up to 12 rows of seven columns per row. The first three columns constitute a key that together select which row or unique treatment should apply for an incoming call on the group. The remaining four columns specify the treatment to be provided for a call that matches the key. The first column or field in the key is the Service/Feature field. If an incoming call is for a service listed in a row in the incoming call handling table, then that row may specify the treatment for the call, depending on the other two columns of the key. The Called Len field is used to continue the row determination. If the number of digits received with the incoming call match the number of digits in the Called Len field for calls to the matched service, then this row may apply. If no other row also contains a matching service and called length, then this row does apply. If another row does exist with the same service and number length, then the Called Number field will be used to continue the row determination. If the leading digits received with the incoming call match the digits specified in the Called Number field, then this row applies to the call. Therefore, with this table, a unique treatment can be given to any incoming call, even if these calls are to the same service or have the same length of digits. The remaining four fields specify the unique treatment for the call once the row has been determined. Together, the Del and Insert fields can be used to manipulate the incoming number that will be used to route the call. The Per Call SID/ANI field can be used to request SID/ANI only for specific calls incoming on the group. The Night Serv field is used to have calls of different types routed to different night destinations when night service is in effect. The biggest application of this table is when a Generic 1 is connected to the public network with several different services, such as MEGACOM® 800 service and ACCUNET® Switched Digital Services, but it also has applications when used in a private network.½ NOTE: Administering this table is optional. Figure 7-80, Trunk Features Screen, Page 2 (ISDN-PRI), depicts this procedure.½ ADDENDUM 1 (December 1990) to 555-025-101, Issue 4

Send SID½ This field determines whether the Station Identification (SID) number is sent to the network for both incoming and/or outgoing ISDN calls. For outgoing calls, the user’s calling party number is sent. For incoming calls, the number associated with the answering party is sent. Field encodes and their descriptions are: y Send the SID. NOTE: If SID is enabled, then the SID PREFIX TABLE screen must be completed. n Do not send the SID (default). NOTE: Both SID and ANI significantly enhance the AT&T ISDN network capabilities. The customer can subscribe to the SID/ANI service and have a representation of the calling party number forwarded from the AT&T network to the terminating switch. Therefore, consider provisioning and enabling the SID/ANI option as part of the installation/administration process. ADDENDUM 1 (December 1990) to 555-025-101, Issue 4
7-148ADMINISTRATION OPTIONS AND REQUIREMENTS — SYSTEM 75 R1V5 & GENERIC 1 Send NameThis field determines whether the calling (originating) party’s administered name is sent to the network for outgoing calls and whether the connected (answering) party’s name is sent to the network for incoming calls. Field encodes and their descriptions are: y Enable this capability. You can enable this field; however, there may be cases where it is desirable to disable this option (for example, security, privacy, and personal preference). n Disable this capability (default). NOTE: Administering the Send Name field is equivalent to administrating procedure 012, words 1 and 2, with the exception that Generic 1 cannot be administered to transmit the trunk group name.½ Typically, those trunk groups that are administered for cbc service type will receive a variety of incoming call types. These incoming calls may originate from a variety of sources (for example, public network, private network, or host computer). The incoming call handling software processes incoming calls based on: l The number of digits received l The type of digits l Whether the call has an identifying NSF (for example, MEGACOM 800, SDN, or ACCUNET) Service/Feature Permitted entries include any of the predefine or additional Services/Feature listed on the NETWORK FACILITIES screen and supported by this trunk group. Also, the special identifier, other, may be translated (as a catch-all entry) for all Services/Features not explicitly specified. The Service/Feature field is the first item searched. Following a match in the Service/Feature field, then the associated entry for the Called Len field is searched, and if a match is found then the Called Number field is searched. Failure to match the associated Called Len or Called Number will cause the search to continue to the next Service/Feature entry. (For a list of predefined Service/Features that can be received, see the Service Type field description.) Called Len Specifies the expected number of digits to be contained in the called-party number IE. Field encodes and their descriptions are: l A number within the range (0 to 16) — the number of digits received must match the number that is administered in this field. If the IXC is AT&T and if the ISDN network service is MEGACOM 800, SDN, or a switched digital service, then a 4ESS may deliver from 0 to 7 digits. Therefore, if the service is correctly provisioned, then the proper number (and required number) of digits will be delivered to the switch.½ l No entry, leave the field blank. This will suffice for the case where the number of digits received is not significant. ADDENDUM 1 (December 1990) to 555-025-101, Issue 4
ADMINISTRATION OPTIONS AND REQUIREMENTS — SYSTEM 75 R1V5 & GENERIC 17-149 CalledGenerally, this field only specifies some of the leading digits that are contained in the Numbercalled-party number IE. The digits received must match, on a digit-per-digit basis, what is administered in this field. Field encodes and their descriptions are: l A series of numbers, which may consist of from 1 to 16 digits, corresponding to the required leading digits. NOTE: If this field is administered then the associated Called Len field must also be administered. l No entry, leave the field blank. This will suffice for the case where the digits received are not significant. DelThe digit Del and digit Insert fields (together) provide the ability to do digit manipulation/digit replacement on incoming calls. It is the manipulated number that is used to route the call. The Del field specifies the number of leading digits to be deleted from the Called Party Number IE. Once the specified number of digits have been deleted, the digits specified in the Insert field are prepended to the front of the Called Party Number. Field encodes and their descriptions are: l A series of numbers, which may consists of from 1 to 16 digits, corresponding to the leading digits that are to be deleted. This administration option may be used to solve many of the problems relating to cross dial plan mapping. Application Example #1 If the called-party number IE contains a 4 digit number (that uniquely identifies an extension or hunt group) but does not align with the required address because the switch has a 5 digit dial plan. Then, the appropriate leading digit may be inserted so that the call will route correctly. Application Example #2 If the called-party number IE contains the digits [8123] or [8567] but it is desired to route these calls to hunt groups with extensions [44123] and [44567] respectively. Then, the screen would have an entry for each number, and the Del fields would contain a one and the Insert fields would contain the digits 44. NOTE: The number of digits deleted cannot be greater than the number specified in the Called Len field. l No entry, leave the field blank. When no digits are to be deleted. l The word all. This option may be used to route particular types of calls to a specific extension number. This specific extension number would be administered in the Insert field.

7-150ADMINISTRATION OPTIONS AND REQUIREMENTS — SYSTEM 75 R1V5 & GENERIC 1 InsertThe digits inserted before the Called Party Number IE. This specifies the digits prepended to the front of the remaining digits after any (optional) digit deletion has been performed. The resultant number formed from digit deletion/insertion is used to route the call, providing that night service is not in effect. Field encodes and their descriptions are: l A series of numbers, which may consists of from 1 to 16 digits. l No entry, leave the field blank. This will suffice for the case where no digits are to be inserted. Per Call Specifies if and how to request SID or ANI for this particular type of Service/Feature. SID/ANIField encodes and their descriptions are: l l l l l lNo entry, leave the field blank (default). Specifies that the switch will not request either SID or ANI for any of these types of calls after call delivery. Use no entry when the network is provisioned to always send SID/ANI with call setup. ANI-only ANI-pref — but will accept SID SID-only SID-pref — but will accept ANI None — same as blank Night Serv Permits the administration of a particular night service extension for each row in the table. This entry will override the night service administered for the whole trunk group (on page 1 of the TRUNK GROUP screen). Field encodes and their descriptions are: l An extension number l The attendant l No entry, leave the field blank (default). This will not override night service for the whole trunk group. The TRUNK FEATURES screen (Page 2 of 11) may have more than one entry for the same Service/Feature. Frequently, multiple entries (per Service/Feature) are used to provide multiple call routes for that Service/Feature. The route selected will be dependent on the received digits and specific administration details of the digit manipulation fields. If an incoming call matches more than one entry, then the most restrictive entry is selected. (This is why it is not CBC specific.) The following case examples show this point and should clarify how the incoming call handling software functions in this scenario. Case 1 l Service/Feature field is specified (for example, mega800). l Called Len field is specified with a requirement of N digits (for example, N = 5). l Called Number field is specified with M leading digits, where M is a number of digits less than N (for example, the three digits 855). ADDENDUM 1 (December 1990) to 55S-025-101, Issue 4
ADMINISTRATION OPTIONS AND REQUIREMENTS — SYSTEM 75 R1V5 & GENERIC 17-151 NOTE: The screen that follows these case examples depicts a line entry (Service/Feature, Called Len, Called Number,...) for each case. The first (top) entry is for case 1, the second entry from the top is for case 2,...the last entry shown is for case 7. Case 2 l Service/Feature field is specified (for example, mega800). l Called Len field is specified with a requirement of N digits (for example, N = 5). l Called Number field is specified with M leading digits, where M is a number of digits less than N (for example, the single digit 8). Application for Case 1 being selected — most restrictive Assume the switch receives a MEGACOM 800 call that has a called-party number IE with 85542. Based on the Service/Feature and Called Len fields alone, this call will match both case 1 and case 2. However, on analyzing the called-party number, the incoming call handling software will select Case 1 since it is the more restrictive match. Each incoming call is searched against every screen entry to identify the appropriate match. Application for Case 2 being selected Assume the switch receives a MEGACOM 800 call that has a called-party number IE with the digits 84000. Based on the Service/Feature and Called Len fields alone, this call will match both Case 1 and case 2. However, on analyzing the called-party number, it is determined that the leading digits (84000) do not match the digits for Case 1 but do match for Case 2. Case 3 l Service/Feature field is specified (for example, mega800). l Called Len field is specified (for example, 4). l Called Number field is not specified (that is, left blank). Application for Case 3 being selected A MEGACOM 800 call is received that has a called-party number IE with the digits 8654. Based on the Service/Feature field alone, this call matches Cases 1-3. However, on analyzing the Called Party Number IE, there are only 4 leading digits (8654). Cases 1 and 2 are eliminated since they require a Called Len of 5 digits (Case 3 requires 4 digits). Furthermore, the Case 3 Called Number field is blank, which matches any number regardless of digit format. The incoming call handling software selects Case 3 since it matches and is more restrictive than Cases 4-7. ADDENDUM 1 (December 1990) to 555-025-101, Issue 4
7-152ADMINISTRATION OPTIONS AND REQUIREMENTS — SYSTEM 75 R1V5 & GENERIC 1 Case 4 l Service/Feature field is specified (for example, mega800). l Called Len field is not specified (that is, left blank). l Called Number field is not specified (that is, left blank). Application for Case 4 being selected Assume the switch receives a MEGACOM 800 call that has a called-party number IE with the digits 75442. Based on the Service/Feature field alone, this call will match Case 1, 2, 3, and 4. However, on analyzing the Called Party Number IE, it is determined that there are the following 5 leading digits (75442). Case 3 does not match because it requires 4 digits. Case 1 and 2 both require 5 digits, but specify an 8 as the leading digit and therefore do not match. For Case 4, the Called Len and Called Number fields are blank, which matches any number regardless of the number of digits or digit format. Case 5 l Service/Feature field is specified as other. l Called Len field is specified with a requirement of N digits (for example, N = 5). l Called Number field is specified with M leading digits, where M is a number of digits less than N (for example, the three digits 855). Case 6 l Service/Feature field is specified as other. l Called Len field is specified with a requirement of N digits (for example, N = 5). l Called Number field is specified with M leading digits, where M is a number of digits less than N (for example, the single digit 8). Case 7 l Service/Feature field is specified (for example, other) l Called Len field is specified (for example, N) l Called Number field is not specified (that is, left blank) Case 8 l Service/Feature field is specified (for example, other) l Called Len field is not specified (that is, left blank).
