Table 2.4.4 Capacity of digital terminals
There are KD, KD/E, KD/C, LKD series DKTU, KD and KD/E DSS, Digital Phone box, and external CTI
module as LG digital terminals. KD, KD/(E)C, external CTI module and Data Module are not available
now due to the production stop.
See clause 2.4.12.3 2B-module and clause 2.4.12.4 GDK-PC phone on section 2 for more details
regarding 2B-module and CTI module.
Digital Interface Board provides digital voice and data communications to/from digital terminals. The
board allows for either 1 or 2 bearer channels from a single hardware interface under the control of
system software.
A industry standard RJ21 type female connector is mounted on the front edge of the PCB for connection
to the station interfaces. In addition, one LED is mounted on the PCB to indicate the in use state of the
connected terminals. It will turn on when one or more ports are busy.
DTIB12/DTIB24 can be installed in the universal slot No. 1-6 in any KSU.
