Nortel DMS-100 Line-to-Line 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 final destination or termination of the call.

Operation

Line-to-line 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 + ----> + Lines +
+++++++++       +++++++++++++       +++++++++++       +++++++++

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 prior to 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.

Translations Table Flow for Line-to-Line 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.  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 to determine what these features are.



Field LNATTIDX in table LENLINES points to a tuple in table LINEATTR.  The entries in this tuple determine the following:

Verification of the call type is done in table LCASCRCN and its subtable LCASCR and table PFXTREAT.

The call then routes to table STDPRTCT and its subtable STDPRT.  The pretranslator route selector entered in subfield PRERTSEL determines how call processing progresses.  Information on the valid values for this subfield can be located in the table data schema section of this document.

If the entry in this subfield is N, translations proceeds to table HNPACONT and its subtable HNPACODE.  The dialed NXX is located and defined.

Table TOFCNAME defines all the terminating offices in the switch and they are identified by area code and office code.  Table DNINV contains the data for all assigned and unassigned DNs.  If the DN belongs to a hunt group, tables HUNTGRP and HUNTMEM will be accessed.

The line-to-line translations process is shown in the flowchart that follows on the next page.




































Table Flow for a Line-to-Line Call









The following table lists the datafill content used in the flowchart for a call routed between DNs (418) 225-2136 and (418) 225-2164.  In the example:

Number Planning Area (NPA) = 418
           Calling Line DN = 2252136
            Called Line DN = 2252164
