Nortel DMS-100 Incoming End Office Trunk Group Type

Incoming End Office Trunk Group Type

In a DMS office, incoming trunk group type TI connects with an end or toll office for local, direct, or tandem switching.

If the trunk group uses dial pulse signaling and trunk-to-trunk overlap outpulsing, the variable number of digits format is required.  The minimum number of digits specified is the number of digits received before overlap outpulsing starts.

Datafill

For trunk group type TI, table TRIGGRP must be datafilled before table TRKGRP.  For additional dependencies, refer to section "Table Size" in table TRKGRP.

The following table lists the datafill for table TRKGRP, type TI.

                                             It is recommended that incoming and outgoing
					     traffic separation numbers 1 to 9 be reserved
					     for generic traffic separation numbers.




         PADGRP          Alphanumeric        Pad Group
                         (1 to 5             Enter the name of the pad group assigned to 
			 characters)         the trunk group in table PADDATA.

			                     Refer to the description of table PADDATA
					     (Pad Data) for additional information.

         NCCLS           NCRT                Operational Measurements No-Circuit Class
	                                     This field is not required for incoming trunk 
					     groups.  Enter "NCRT" (no circuit). 

         TRAFCLS         Alphanumeric        Traffic Usage Class
	                 (2 characters)      Enter the traffic usage class assigned to 
					     the trunk group.

         PRTNM           Alphanumeric        Standard Pretranslation Name
	                 (1 to 4             Enter the name of the standard pretranslator
			 characters) or      datafilled in table STDPRTCT to which translation
			 NPRT                routes on receipt of the first incoming digit.
			                     If pretranslation is not required, enter "NPRT"
					     (no pretranslator).  If office parameter 
					     TRK_OOS_CHK_ON in table OFCVAR is set to "Y", all
					     trunks in the group must be busy before the value
					     of this field can be changed by Data Modification 
					     Order (DMO).

         SCRNCL          Alphanumeric        Class of Service Screening Table Name
	                 (1 to 32            If class-of-service screening is required, enter
			 characters) or      the name of the class-of-service screening table 
			 NSCR                (datafilled in table SCRNCLAS) to which digit

					     If office parameter TRK_OOS_CHK_ON in table
					     OFCVAR is set to "Y", all trunks in the group
					     must be busy before the value of this field can

	                                     Enter the originating source LCL (local) or NLCL
					     (non-local).

         VDEVAR          See Subfield        Variable Digit Data
                                             This field consists of subfield VDESEL.

         VDESEL          Y or N              Variable Digit Selector
	                                     If the number of incoming digits is variable,
					     enter "Y" and datafill refinements DIGSIN1 and
					     DIGSIN2.  If the number of incoming digits is a
					     fixed quantity, enter "N" and datafill refinement
					     DIGREGEN.

                                             If office parameter TRK_OOS_CHK_ON in table OFCVAR
					     is set to "Y", all trunks in the group must be busy
					     before the value of this field can be changed by
					     DMO.




         DIGSIN1         Numeric             Minimum Number of Incoming Digits
	                 (1 to 18)           If the entry in field VDESEL is "Y", enter the 
			                     minimum number of incoming digits that can be
					     received on the trunk group.  Entries outside the 
					     range indicated for this field are not valid.

					     If office parameter TRK_OOS_CHK_ON in table OFCVAR
					     is set to "Y" (yes), all trunks in the group must
					     be busy before the value of this field can be 
					     changed by DMO.

         DIGSIN2         Numeric             Maximum Number of Incoming Digits
	                 (1 to 18)           If the entry in field VDESEL is "Y', enter the
			                     maximum number of incoming digits that can be
					     received on the trunk group.  Entries outside the
					     range indicated for this field are not valid.

					     If office parameter TRK_OOS_CHK_ON in table OFCVAR
					     is set to "Y" (yes), all trunks in the group must
					     be busy before the value of this field can be
					     changed by DMO.

         DIGREGEN        Numeric             Digits to be Regenerated
	                 (1 to 4 digits)     If the entry in field VDESEL is "N", enter the 
			 or N                digit string (one to four digits) to be prefixed
			                     to the incoming digits to regenerate a seven-digit
					     number.  The length of the digit string entered is
					     subtracted from seven by the switch to determine
					     the number of incoming digits to expect.

                                             The regenerated number is then translated in table
					     STDPRTCT.STDPRT or HNPACONT.HNPACODE, or both.

                                             For example, if the entry is 73, the switch expects
					     five incoming digits XXXXX and regenerates the
					     number 73XXXXX.

                                             If no digits are to be prefixed, enter "N". 
					     The switch then expects seven incoming digits.

         OPTIONS         See Subfield        Options
	                                     This field consists of up to two multiples of
					     subfield OPTION and refinements.

         OPTION          BCNAME              Option
	                                     To specify the bearer-capability-name option, 
					     enter "BCNAME" and datafill refinement BCNAME.
                                             If option BCNAME does not apply, leave this field
					     blank.

         BCNAME          Alphanumeric        Bearer Capability Name
	                 (1 to 16            If the entry in field OPTION is "BCNAME", enter
			 characters)         the bearer capability to be used by this trunk
			                     group.  Refer to table BCDEF for the current
					     list of available bearer capabilities.
