2.4.8.2 SLIB24/SLIB48 (Single Line Interface Board With 6 Ports)
SLIB allows single line analog devices to be connected.
Five kinds of SLIB boards are available in ARIA-130 system;
Board Name Interface circuit Feed voltage Remark
SLIB24 6 ports +24V DC feed
SLIB48 6 ports -48V DC feed Maximum 2card in each KSU
SLIBII 12 ports -28V DC feed See clause 2.4.8.3
SLIB2E 12 ports -28V DC feed See clause 2.4.8.4
DSIB 6 ports +24V DC feed See clause 2.4.8.5
Table 2.4.5 Capacity of SLT boards
DSIB provides 6 digital terminal interfaces and 6 single line analog interfaces. For SLIB II and DSIB, see
the parts of SLIBII and DSIB in this section.
SLIB24/SLIB48 are capable of accommodating up to 6 single line analog devices. The boards are
configured with hybrid circuit and CODEC; converts A/D and D/A signal. SLIB24/SLIB48 allow the SLT
access to CO Lines connected to the system, other stations, and most features of the system through the
use of dial codes. Connections to the SLIB are made through RJ21 type female connector.
The SLIB24/SLIB48 can be equipped with a Message Wait source (optional MSGU for SLIB24 or
MSGU48 for SLIB48), which activates 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 the
cabinet where a SLIB is installed. An optional DTMF receiver unit (DTRU) can be installed on the
SLIB24/SLIB48.
The SLIB24 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. The SLIB48 allows a SLT to be connected up
to 5 Kilometers (16,500 feet, loop resistance: 790 ohm) from the system using 22 AWG wire. See the
Table 2.3.5.
In addition, one LED is mounted on the PCB to indicate the in use status of ports connected to SLIB. It
will turn on when one or more ports are busy.
The SLIB24/SLIB48 can be installed in the universal slot No. 1-6 in any KSU.
Add-on boards: DTRU, MSGU (for SLIB24), MSGU48 (for SLIB48)
2.4.8.3 SLIB II (Single Line Interface Board with 12 Ports)
SLIB II provides the capability to connect 12 single line analog terminals to the system with appropriate
A/D and D/A conversions. SLIB II is -28V DC feeding voltage. The SLIB II allows the SLT access to CO
Lines connected to the system, other stations, and most features of the system through the use of dial
codes. Connections to the SLIB II are made through RJ21 type female connector.
The SLIB II is equipped with a Message Wait source, optional MSGU II, which activates 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 SLIB II is installed.
An optional DTMF receiver unit (DTRU II) can be installed on the SLIB II.
