Expanded Multiple Line Operation - DtermE-26
E-26  Expanded Multiple Line Operation - Dterm
          (Series 7400 software feature)
General Description
This feature allows operation of whichever lines from ELC card(s) in the same IMG or in different IMGs in the same
node, as a Dterm’s programmable Multiple Lines (My Line + Prime Line/Sub Lines). While Multiple Line Operation
- Dterm [M-20] only allows such a programming within the reach of ELC card(s) in the same IMG, this feature
enables the Multiple Line Operation beyond the reach of a single IMG (though the ELCs cannot be in different
nodes).
Note:To use Multiple Lines beyond different IMGs, the Dterm My Line must be accommodated on the PA-16ELCJ-B card.
For details, refer to the figure (and Service Conditions) below:
Operating Procedure
No manual operation is required.
Service Conditions
1. To use this feature (operation of Multiple Lines beyond different IMGs), a PA-16ELCJ-B(ELC) circuit
card is required.
2. Depending on the switch setting on PA-16ELCJ-B, the assignable Multiple Lines vary.
a.) PA-16ELCJ-B, SW10, Element 1 = ON: A D
term My Line, accommodated on this card, and the
other Lines (other analog telephone/Dterm) must be in
the same IMG.

Service Conditions (cont’d)
b.) PA-16ELCJ-B, SW10, Element 1 = OFF: A  Dterm, accommodated on this card, and the other
Lines (other analog telephone/Dterm) can be in
different IMGs (but in the same node). For more
details on the PA-16ELCJ-B circuit card, refer to the
NEAX2400 IMX Circuit Card Manual.
Note:Even when Element 1 of SW10 is ON, data programming for this feature (Multiple Lines beyond different IMGs) is
possible. However, the data does not become effective until the switch is manually placed to OFF.
3. A Dterm cannot register a Sub Line accommodated on an ELC card in a different node (having a different
CPU). Therefore, if your system is an IMX-U (16-IMG) type, this feature must be programmed on a node
basis.
4. Three kinds of lines can appear on a D
term line/feature key:
 MY Line (ML):This line is associated with the extension number assigned to the port on the interface
circuit. 
 Prime Line (PL):This line is given priority for outgoing and incoming calls. The prime line is
automatically seized when going off-hook.
 Sub Line (SL):This line designates any other line appearing on a D
term. The MY Line will serve as a
prime line, unless differentiated in system data programming.
5. A maximum of 32 PA-16ELCJ-B cards (a total of 512 ports) can be used for this feature (Multiple Lines
beyond different IMGs), per node.
Note:This is not the case if the Multiple Lines are programmed in a single IMG.
6. If the system is a 1-IMG type, this feature is not available.
7. A virtual line (Software Line Appearance [S-33]), single line telephone or D
term can be assigned as a
subline.
8. To use this feature, flag “1” to the ASYD command, SYS 1, INDEX 321, b0.
9. When KD = 1 (Intercom) or KD = 2(DSS Key) is assigned on the AKYD command, this service is not
available. Be sure to assign KD = 0 (Line).

F-1 Flexible Numbering of Stations
General Description
This feature provides the ability to assign telephone numbers of the voice station and data station to any
corresponding instrument location, depending solely upon numbering plan limitations.
Operating Procedure
Refer to the NEAX2400 IMX Office Data Specification.
Service Conditions
1. Careful consideration should be given to any numbering assignment, especially in larger systems, to avoid
the unnecessary loss of access codes or duplication of telephone numbers. There is no limit to the number
of groups that can be assigned per system.
2. Where TENANT SERVICE [T-12] is provided, telephone numbers may not be duplicated between
tenants. A combination of one, two, three, four and five-digit numbering may be used.
Example: a. 3 1
b.321
c.3221
Example a., b., c., can be assigned as 3 different stations.
3. BUSY LAMP FIELD - FLEXIBLE [B-2] service can be provided only when the defining telephone
number digits exceed two.
4. The FCCS network allows the user to use a telephone number in addition to the existing station numbers.
FCCS service features are activated when a telephone number is dialed. A telephone number, which can
be assigned on a station basis, is a unique number on the FCCS network.
Note:A maximum of 16 digits can be used as a telephone number. When OAI/ACD/Hospitality features are used, a maximum
of 5 digits can be used.
Interactions
Caution should be exercised when programming this feature. Large quantities of potential telephone numbers are
consumed. As programmed below, the system will be equipped with just one 2-digit station and one 3-digit station.
