Single Line Interface Board (2 Port with built-in Msg Wait)
The Single Line Interface Board (SLIB2) provides the interface to two 2500-type telephones. 
The SLIB signals interface with industry-standard ringers and message waiting lights. The 
2-port SLIB always occupies slot 2 and is standard on the BKSU. It can be removed if necessary 
by the installer.
The two ports provided by this board are connected to SLT devices by using the two RJ11 
modular connectors on the right side of the BKSU.
Additional SLIB devices can be added using one or more optional SLIB4s. Refer to “Single Line 
Interface Board - 4 Port” on page 3-15.

Expansion Board Installation
Boards and daughter boards discussed in this section are optional boards that can be used to 
increase the capacity of your system.
Digital Telephone Interface Board
The optional Digital Telephone Interface Board (DTIB) provides digital voice and data 
communications to/from digital telephones. The DTIB board provides the interface to eight 
digital telephones. The card has one LED to indicate off-hook/in use status.

Loop Start CO Interface Board (with Caller ID)
The optional Loop Start CO Interface Board (LCOB) supports up to four Loop Start Central Office 
Lines and comes equipped with a Caller ID Unit (CIDU) to detect Caller ID information.
The CIDU provides four Caller ID interfaces for the LCOB.

Single Line Interface Board - 4 Port
The optional Single Line Interface Board (SLIB4) provides the interface to four 2500-type 
telephones. The SLIB signals interface with industry-standard ringers and message waiting 
lights. In addition, one LED is mounted on the PCB to indicate the in use state of the 
connected telephones. It will turn on when one or more ports are busy. The optional 4-port 
SLIB4 may be added to the BKSU or EKSU to expand the number of single lines stations, and 
can support an MSGU48 board in a daughter-board-type arrangement.

Message Wait Unit
The Message Wait Unit (MSGU48) provides message wait lamp relay control for message lamp 
single line telephones. The MSGU48 board mounts as a daughter board on the SLIB4. The SLIB 
interfaces with mechanical 90V AC ringers and 95V DC lights on 2500-type phone sets.
Installing the MSGU48 to SLIB4:
1. Using a ground strap, unpack the MSGU48 from its antistatic conductive bag.
2. Locate the CONN1 and CONN2 connectors on the MSGU48.
3. Locate the CN1 and CN2 connectors on the SLIB4.
4. Align CONN1 & CONN2 of the MSGU48 to match CN2 & CN1 on the SLIB4, respectively.

T1 Interface Board
The optional T1IB provides the T1 (1.544Mbps, 24 channel) interface circuit, control circuitry, 
and synchronous clock control circuits. Up to two DTMF tone detection units (DTRU4) can 
optionally be installed on the T1IB.
The system can be equipped with one T1IB and it can be installed in slots 5, 6, or 7 of the BKSU 
or in slots 11, 12, or 13 in the EKSU. The Phase Lock Loop Unit (PLLU) must be installed in the 
BKSU for the T1 card to operate properly.
The T1IB has eight LEDs on the front edge of the PCB which indicate errors of T1 line, in-use 
status, and synchronous clock enable status.

Chapter 3 - Installation
The T1IB contains two switches (SW1 and SW3). The clock selection switch (SW3) is used for 
control of synchronous clock. The Line Build-Out switch (SW1) is controlled by the distance 
between the STS system and a CSU and SW1 #4 is used for loopback control.
The Line Build-Out switch setting is based on distance between the STS System and a CSU. The 
proper switch settings are indicated in the following table. If the CSU is located near the KSU, 
all LBO switches should be ON.
The SW1 switch #4 of the Line Build-Out switch is used for Loopback control. Its switch is used 
only for hardware test and must be placed in the ON position for normal operation.
T1 Ordering Information: When ordering a T1 circuit from a carrier, request either D4 
framing and Alternate Mark Inversion (AMI) Line coding using the superframe (SF) or the 
Extended Superframe (ESF-B8ZS) format. The following are additional ordering information

Chapter 3 - Installation

This board supports standard D4 framing format with robbed bit signaling. Extended 
Super Frame (ESF) format with B8ZS is also supported.

The board requires an external CSU unit.

The T1 board can accept two DTRU4 units in a daughter board type arrangement. Each 
unit has four DTMF Receivers installed on it.

The board has an RJ45 connector for connection to a CSU unit.
Functionality Description

Automatic Number Identification (ANI) information from the carrier is treated exactly 
the same as an inbound ICLID (Caller ID) number. Calls can be routed, placed in the 
Unanswered Call Table, sent out to the CTI Module port on a keyset, and run through the 
Number To Name Translation Table. The STS system provides call progress tones in the 
same manner as ICLID.

Dialed Number Identification Service (DNIS) information from the carrier is treated 
using DID line rules. DNIS calls are routed based on the DID Routing Table.

ANI/DNIS is a combined format, where the system waits for the ANI/DNIS information 
from the carrier. When it is received, the system routes the call using ICLID processing. If 
this information is not found in the ICLID Route Tables, the DNIS information is compared 
to the DID table for a match. The call is then routed based on the DID tables. If a match is 
not found on either the ANI or DNIS number, the call is routed based on normal CO line 
operation (CO Ringing Assignments).
The following table summarizes the operation of the system.
Table 3-4: Call Routing Criteria
ANI DNIS Operation
N N Calls routed based on normal CO operation (CO Ring Assignments.
N Y Calls routed based on DID tables with DID operation.
Y N Calls routed based on ICLID routing and ICLID operation.
Y* Y Calls routed on ICLID first, if no route is found, the DNIS digits are 
compared to the DID table. If no route is found in the DID table the 
call is routed based on CO line Ringing Assignments.
*If both ANI and DNIS calls are routed -- the following table summarizes what is displayed at the phone.
The T1 card accepts ANI/DNIS information in a DTMF format only. Some carriers do not 
provide ANI or ANI/DNIS in a DTMF format. Consult your local carrier for available 
options.

Phase Lock Loop Unit
The Phase Lock Loop Unit (PLLU) is an option board 
which generates a 32.768MHz clock synchronized to 
1.544MHz from the T1 interface board or internal 
clock.
This board is required whenever a T1 card is installed in 
the system. The 32.768MHz clock is provided to CGMD 
on MBU. It consists of a PLL circuit, PLL Monitoring 
circuit and clock (from T1 interface board) monitoring 
circuit.
The PLLU is installed in the upper center of the BKSU. 
Refer to Figure 3-7: PLLU Location.
