3.4.4 Extension Board Installation
The system can be equipped with any combination of the extension boards; DTIB12, DTIB24, ETIB,
SLIB24, SLIB48, SLIBII, DSIB, and WTIB. The station interface boards can be installed in any card slots in
the Basic and Expansion KSU except in MPB slot of the Basic KSU. But WTIB can not be installed in slot 8
of BKSU and in any slot of EKSU.
It is recommended to install extension boards, e.g. DTIB from the left most slot (slot No.1). Also, since the
first port of SLOT # 1 will be the database access port, it is recommended that a DTIB be installed in this slot
and a Digital Keyset with display be connected to this port.
3.4.4.1 DTIB12/DTIB24 Installation
DTIB12/DTIB24/DSIB can be installed in any card slot in the Basic and Expansion KSU except in MPB slot
of the Basic KSU.
Since the first port of SLOT 1 will be the database access port, it is recommended that a DTIB12, DTIB24
or DSIB be installed in this slot and a digital keyset with display be connected to this port.

Note:
1) The distance between Digital Terminal Interface Board and Digital Terminal: see Table 2.3.4
In GDK-100 system, LDK-30DS with 2B-module and secondary terminal can be connected to only every
even-numbered port (0,2,4,…) of DTIB12/DTIB24/DSIB, then any digital terminal can not be connected to
the consecutive odd port(1,3,5,…) in that case. See clause 2.4.13.4 2B-module and clause 2.4.13.5 GDK-PC
PHONE in section 2 for more details regarding 2B-module and CTI module.
DTIB12/DTIB24 can be installed in any of slot No. 1-12.
The maximum extension boards except Wireless Terminals are limited by 72 extensions in a
system.
So It is recommended that a board among DTIB12, DTIB24 and DSIB is installed in the most left slot and a
Digital Keyset with display is connected to the first port the board when the first initialization of the system,
since the FIRST STATION of the system at first can only access the system database without PC
Administration. See clause 3.4.2 MPB Installation.
