2.4.8.5 DSIB (DKTU/SLT Interface Board with 12 Ports)
DSIB provides 6 SLT and 6 DKT interfaces. Connections to the DSIB are made through RJ21 type female
connector. An LED is mounted on the PCB to indicate the status of ports connected to SLIB. It will turn on
when one or more ports are busy.
6 DKT interface circuits on this board have the same characteristics that those on DTIB12/24 do. See the
part of DTIB12/DTIB24 in this section. 6 SLT interface circuits on this board also have the same
characteristics as SLIB24. DSIB is +24V DC feeding voltage. The DSIB is equipped with a Message Wait
source, optional MSGU, which activate a lamp in the SLT, if so equipped. The Message Wait source
sends 90V DC signal to the SLT illuminating the MW lamp. A Ring Generator Unit is required in cabinet
where a DSIB is installed.
The DSIB allows a Single Line Telephone to be connected up to 2.5 Kilometers (8,200 feet, loop
resistance: 490 ohm) from the system using 22 AWG wire. See the Table 2.3.5. The DSIB also allows a
DKTU to be connected up to 0.5 Kilometers (1600 feet) from the system using 22 AWG wire. See the
Table 2.3.5 and Table 2.3.6.
The DSIB can be installed in the universal slot No. 1-6 in any KSU.
The maximum extension ports are limited by 96 extensions in ARIA-130 system.
Add-on boards: DTRU, MSGU
2.4.8.6 WTIB / WTIU (Wireless Terminal Interface Board / Unit)
The WTIB provides standard interface between the ARIA-130 digital Key Telephone system and DECT
(Digital Enhanced Cordless Telecommunications) Network. The system can accommodate two WTIBs in
the same KSU, which are capable of supporting up to 16 Base Stations. The WTIB can be optionally
equipped with WTIU to expand Base Stations, which can support up to additional 4 base stations. So one
WTIB with WTIU allows maximum 8 Base Stations to be connected.
Following table shows the capacity of WTIB and its expansion board.
