Note
1. CON1: Trace for the purpose of development and maintenance.
The external module for RS-232C serial interface should be required for trace.
See GDK-TRC1 in section 2.4.15.
2. CON3, CON4: They are used to control the reference clock signal when multi-ISDN boards
are installed. See [Clock Control Cable Wiring] on section 3.5.7.5.

Note:
1. The setting method of S/T selection switches: default -all T position while delivering the
board.
2. Each line interface can be used for T interface or S interface with different operation
interface. If necessary, the S/T selection switches of SW2, SW3, SW4 and/or SW5 can be
respectively set to the T or S position by using shorting traps (short pins) supplied on the
boards.
3. Two poles of SW6, SW7, SW8 and/or SW9 should set to the ON position to terminate two
terminating resistors on a line. (default ON)
4. Terminating resistors and selectable switches are introduced only on PCB issue 2 or
later, but not on PCB issue 1. So if you use STIB issue 1, the external terminating
resistors are required. For the external termination, you can get the terminating unit
locally or use GDK-162/100 TERM, which is the terminating unit with 4 P-to-P
connection provided by LG.

Note:
1. Each line can be selected to T or S interface according to the needs.
2. After setting all lines respectively, the slot(s) of STIB must be assigned as CO slot(s) and
STA slot(s) together in Admin field 02 for the proper operation of STIB. See the clause 4.2
and the Programming Manual.
