Nortel DMS-100 Line-to-Trunk Translations |
Description
When a call originates from a line, the associated line tables are read and interpreted. The call then enters the screening tables where digit analysis begins. After some general pre-screening or pre-translation is performed, the call may progress into more detailed screening based on NPA-NXX digits to determine the path into the designated routing tables for defining the destination trunk for termination of the call.
Operation
Line-to-trunk translations can be traced using a simplified block diagram, representing the major functions within the translation process, as shown in the following figure:
+++++++++ +++++++++++++ +++++++++++ ++++++++++ + Lines + ----> + Screening + ----> + Routing + ----> + Trunks + +++++++++ +++++++++++++ +++++++++++ ++++++++++
The lines tables contain information about the originator of the call in a DMS-100 switch. These tables have three primary functions:
The screening tables contain the information used to analyze the digits that the DMS-100 switch receives. This screening process tests the digits dialed before continuing to the next routing stage, to determine, for example, whether this call is local or non-local.
The screening tables establish the call type based on the digits received. The three basic call types are:
The routing tables route the calls to their final destination. The information found in these tables dictates how and where a call will be completed, or if the call will route to a recorded announcement or treatment.
The trunking tables contain detailed information about trunks originating and terminating in the DMS-100. Each trunk connected to the office is represented by entries in trunk tables.
Translations Table Flow for Line-to-Trunk Translations
As soon as a line goes off-hook, the associated Line Concentrating Module (LCM) informs the switch that the line went off hook and provides the Line Equipment Number (LEN). The originating line has its LEN stored in table LENLINES (Line Assignment). From the data stored in table LENLINES, the switch determines the Directory Number (DN), party, and options of the line. If there are features associated with the line, the switch accesses table LENFEAT (Line Features) to determine what these features are.
Field LNATTIDX (Line Attribute Index) in table LENLINES points to a tuple in table LINEATTR (Line Attributes). The entries in this tuple determine the following:
Verification of the call type is done in table LCASCRCN (Local Calling Area Screening Control) and its subtable LCASCR and in table PFXTREAT (Prefix Treatment).
The call then routes to table STDPRTCT and its subtable STDPRT. At this point, call processing will continue either through table HNPACONT and its subtables or through table OFRT (Office Route). The pre-translator route selector entered in subfield PRERTSEL of subtable STDPRT determines how call processing progresses. Information on the valid values for this subfield can be located in the data schema section.
The Common Language Location Identifier (CLLI) of the trunk datafilled in subtable HNPACONT.RTEREF or table OFRT is listed in table CLLI. Trunk group type and screening information are provided in table TRKGRP (Trunk Group). Table TRKSGRP (Trunk Subgroup) defines the signaling and control information and table TRKMEM (Trunk Member) contains the physical location of each trunk member.
The line-to-trunk translations process is shown in the flowchart that follows.
