5.21.2.1.2. Closed-numbered area with analog CO connection 
The system configuration corresponds to that shown in Figure
52 with the exception that no digital or analog CO connection
exists. Numbers can be transferred, e.g. in case of MFC (multi-frequency
code) lines (see AMO TACSU, AMO MFCTA).\
In this case, no format-dependent modification can be configured (reason:
NPI/TON are not transferred) so that you must set all modifications with
AMO KNMAT or AMO MFCTA. In this case, the numbering plan is always UNKNOWN.
In this example, no number modification is set in the MFC table.
Configuration in physical node 11
The node prefix and node format tables are not set.
- Set the analog trunk circuit:
ADD-TDCSU:DEVTYPE=...,COTNO=11,COPNO=2,TGRP=44, LCOSV=1,LCOSD=1,NNO=3;
- Configure the LCR route:
LCR is configured as shown in Section . The outdial rule defined using AMO LODR, however, must be different since NPI is always UNKNOWN.
ADD-LODR:ODR=10,CMD=ECHO,FIELD=2; ADD-LODR:ODR=10,CMD=END;
- Set the node connection matrix:
Incoming from the central office, the calling number is supplemented by the exit code 0 in Node 1. This happens if the connection for a subscriber is established at Node 1, but also for connections to subscribers at other nodes.Toward the central office, the number of the main connection is placed before the pure station number at exit node 1 of the calling number so that a correct CO number is provided to the central office.
CHANGE-KNMAT:NPI=UNKNOWN,LEVEL=0,ONNOL=OWN&ROW, DNNO=3,NUMEXT=089722; CHANGE-KNMAT:NPI=UNKNOWN,LEVEL=0,ONNO=3, DNNOL=OWN&ROW,NUMEXT=0;
The following setting results:----------------------------------------------------------------- NODE MATRIX FOR NPI = UNKNOWN, LEVEL = 0, OWN NNO = 1 ----------------------------------------------------------------- ONNO |DNNO |CONN|MODCON| NUMEXT | NUMRED / ONNOL|/ DNNOL| | | | ------+------+----+------+-----------------------------+---------- 1 | 3 | A |ALL | 089722 | - ------+------+----+------+-----------------------------+---------- 3 | 1 | A |ALL | 0 | - 3 |ROW | A |ALL | 0 | - ------+------+----+------+-----------------------------+---------- ROW | 3 | A |ALL | 089722 | -
Configuration in physical node 2
In closed-numbered Node 2, no special setting is required for the
number modification.
