DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 597 Dial Plan Record 17 NOTE: It is recommended that you do not administer extensions that begin with 0 if the Uniform Dialing Plan is enabled. In the United States of America, 0 is usually the attendant. nfac (feature access code) only — a FAC can be any number from 1 to 9 and contain up to 4 digits. You can use * or #, but only as a first digit. It is recommended that a FAC be the last item entered in a row when mixed numbering is used. Otherwise, problems may occur when 3-digit FACs and 4-digit extensions begin with the same first digit and the FAC is an abbreviated dialing list access code. The system requires that FACs for AAR and ARS have the longest length for a first digit in the First Digit Table. nmisc (miscellaneous code) — these codes are used if you want to have more than one kind of code start with the same digit and be the same length. Misc can have a dialed length of 1, and can have a first digit of 0 through 9. Using misc requires that you also define a Second Digit Table. npextension — Is made up of a prefix (first digit) that can be a 0through 9 (* and # not allowed) and an extension number of up to five digits in length. The maximum length of a prefix and extension combination is six digits. When a prefixed extension is entered in the dial plan, a TAC cannot be entered before the prefixed extension on the same row in the table. If a first digit is already assigned as a TAC, a prefixed digit cannot be entered after the TAC on the same row in the table. The purpose of the prefix is to identify the dial type as an extension. After digit collection, the prefix digit is removed from the string of dialed digits. The remaining digits (extension number) are then processed. A prefixed extension allows the use of extensions numbers with any first digit (the extension length must be specified on the table). The prefixed extension cannot have the same first digit as the ARS or AAR facility access code (FAC). NOTE: When a dial plan has mixed station numbering, extensions of various lengths (all with the same first digit) are mapped on the First Digit table as shown on Field descriptions for page 1. The system then employs an inter-digit time-out to ensure that all dialed digits are collected. The inter-digit time-out may add several seconds to the dial time. An alternative to the delay required in the time-out mechanism at the expense of dialing an extra digit is to use prefixed extensions in the dial plan.

Screen 75. DS1 Circuit Pack screen for Channel Associated Signaling
Location
This display-only field shows the port address specified in the
add command
when the circuit pack was first administered.
Name
Use this field to assign a significant, descriptive name to the DS1 link. Lucent
recommends putting the vendor’s circuit ID for the link in this field, because that
information helps you troubleshoot problems with the link, but you could also use
this field to indicate the function or the destination of this DS1 facility. In that
case, put the DS1 link circuit ID in the Name field of the trunk group associated
with this link.
Bit Rate
Use this field to select the maximum transmission rate for DS1 circuit packs that
support either T-1 or E-1 service. For circuit packs that only support one of these
services, the field is a display-only field.
NOTE:
Once an add ds1 operation is complete (that is, the DS1 screen has been
submitted) you can’t change the Bit Rate field with a
change ds1
command. Instead, execute a
remove ds1 command. Then use the add ds1
command to administer the circuit pack again. You’ll have to re-enter all the
information for the circuit pack.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 602 DS1 Circuit Pack 17 TN464C (and later release) circuit packs have an option switch that must be set to match the entry in the Bit Rate field. Line Coding This field selects the type of line coding used on this facility. The setting in this field must match the setting on the far-end of the link, or you must have an intervening CSU to convert the line coding protocols. Voice calls will work even if line coding does not match, but a single data call will bring down the DS1 facility. For the TTC 2Mb CMI Trunk circuit pack, this is a display-only field showing cmi (coded mark inversion). The following information is for reference. Talk with your network service provider or your Lucent representative to find the appropriate protocol for your application. !CAUTION: If you change this field, you must busy out the DS1 circuit pack. You must also change the following screens: Route-Pattern, Access Endpoint, PRI Endpoint, Signaling-Group, and Trunk-Group. NOTE: When the DS1 circuit pack is used for ISDN service, the ISDN D-channel data is inverted when ami-basic or ami-zcs is entered and not inverted when b8zs or hdb3 is entered. Valid entries Usage 1.544 Use for T-1 service. 2.048Use for E-1 service. Valid entries Usage b8zs (bipolar eight zero substitution)Enter b8zs for T-1 facilities that support voice and/or data traffic. Enter b8zs if you need a 64K clear channel. ami-zcs (alternate mark inversion - zero code suppression)Enter ami-zcs only for T-1 facilities that carry voice traffic: it is not recommended for digital-data applications. If you anticipate upgrading this facility to ISDN, use b8zs line coding if possible.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 603 DS1 Circuit Pack 17 Line Compensation The appropriate entry in this field varies with the type of cable used, so work with your network service provider to determine the correct setting in your situation. The following table shows the appropriate entries for different lengths of 22-gauge ABAM cable terminated on a DSX-1 cross-connect. The following table shows the appropriate entries for different lengths of 22-gauge ABAM cable directly connecting to DS1 interfaces. Framing Mode Use this field to select either superframe (sf or d4) or extended superframe (esf) for T1 service on the DS1 link. The framing mode you use must match the mode used on the other end of the link, so work with your network services provider to determine the appropriate entry for this field. ami-basic (alternate mark inversion-basic)Enter ami-basic for unrestricted E-1 facilities. hdb3 (high density bipolar 3)Enter hdb3 for restricted E-1 facilities. cmi (coded mark inversion)Used in Japan, cmi is the only type of line coding you can use with the Japanese 2Mbit trunk circuit pack. This field becomes a display-only field when you are administering the Japanese 2Mbit trunk circuit pack.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 604 DS1 Circuit Pack 17 This field only appears if the Bit Rate field is 1.544 (that is, if you’re using T-1 service). If you’re using E-1 service, DEFINITY ECS automatically selects CEPT1 framing. Tip: Lucent recommends using ESF when your service provider supports it, especially if you may someday upgrade the facility to ISDN. The ESF format provides enhanced performance measurements and uses a sophisticated error-checking method to ensure data integrity. Signaling Mode This field selects the signaling method used for the DS1 link. This mode must match the method used on the other end of the link, so work with your network services provider to determine the appropriate entry for this field. Valid entries Usage d4 Enter d4 to use the basic DS1 superframe (sf). This mode is recommended only for voice traffic. esf Enter esf to use the Extended Superframe format. This mode is recommended for digital data traffic. If you enter esf for a TN464F, TN767E, or a later suffix DS1 circuit pack, a second page of the DS1 Circuit Pack screen becomes available to administer ESF Data Link options. Valid entries Usage CAS (Channel Associated Signaling)Enter CAS for out-of band signaling with E-1 service. This setting yields 30 64-kbps B-channels for voice or data transmission. Channel 0 is used for framing while channel 16 carries signaling. robbed-bitEnter robbed-bit for in-band signaling with T-1 service. This setting yields 24 56-kbps B-channels for voice transmission. isdn-priEnter isdn-pri for either T-1 or E-1 ISDN service. This setting supports both Facility Associated Signaling and Non-Facility Associated Signaling. isdn-extEnter isdn-ext for either T-1 or E-1 ISDN service. This setting supports only Non-Facility Associated Signaling. common-chan Enter common-chan, for out-of-band signaling with T-1 service. This setting yields 23 64-kbps B-channels for voice or data transmission. Channel 24 is used for signaling.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 605 DS1 Circuit Pack 17 D-Channel The Japanese 2Mbit trunk circuit pack, when administered to support ISDN-PRI signaling, allows you to assign the D-channel to any channel from 1 to 31 in an E-1 facility. You cannot submit the screen if this field is blank. Using the change ds1 command, you can change this field if the D-channel is not used in a signaling group. This field appears only when the Location field indicates the circuit pack is a Japanese 2Mbit trunk circuit pack and the Signaling Mode field is isdn-pri. Connect In order to control communications at layers 2 and 3 of the ISDN-PRI protocol, use this field to specify what is on the far end of this DS1 link. This field only appears when the Signaling Mode field is isdn-pri. Interface This field only appears when the Connect field is pbx; that is, when this DS1 link is providing an ISDN-PRI connection in a private network. The Interface field controls how your switch negotiates glare with the far-end switch. The switches at Valid entries Usage 1 to 31 Enter the number of the channel that will be used as the D-channel. Valid entries Usage pbx Enter pbx if this DS1 link is connected to another switch in a private network. If pbx is entered, the Interface field appears. line-sideEnter line-side when the switch is acting as the network side of an ISDN-PRI interface. Use line-side to connect to Roll About Video equipment. network Enter network when the DS1 link connects this switch to a central office or any other public network switch. hostEnter host when the DS1 link connects this switch to a computer.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 606 DS1 Circuit Pack 17 either end of the DS1 link must have complementary settings in this field: if not, the D-channel won’t even come up. For example, if the switch at one end of the link is administered as network, the other must be administered as user. Interconnect For E-1 service using channel-associated signaling, the entry in this field tells DEFINITY ECS whether the DS1 circuit pack is using a public or private network protocol. The entry in this field must agree with the entry in the Group Type field on the Trunk Group screen. This field appears only when the Signaling Mode field is CAS. Country Protocol The entry in this field must match the country protocol used by the far-end switch. For connections to a public network, your network service provider can tell you which country protocol they are using. Valid entries Usage Use the following 2 values for private network applications in the U.S. networkEnter network if your switch overrides the other end when glare occurs. If you are connecting your switch to a host computer, set this field to network. userEnter user if your switch releases the contested circuit and looks for another when glare occurs. If you are connecting your switch to a public network, set this field to user. Use the following values for private networks (including QSIG networks) outside the U.S. Entering either of these values causes the Peer Protocol and Side fields to appear. peer-masterEnter peer-master if your switch overrides the other end when glare occurs. peer-slave Enter peer-slave if your switch releases the contested circuit and looks for another when glare occurs. Valid entries Usage pbx If pbx is selected, the board operates as a tie trunk circuit pack. COIf CO is selected, the board operates as a CO or DID circuit pack.
