STARPLUS STSe - Installation Manual August 2005
General Information
System Overview
The STSe Key Telephone System supports a maximum configuration of 28 CO/PBX/Centrex
lines and 50 station devices. The Basic Key Service Unit (BKSU) and Expansion Key Service Unit
(EKSU) accommodates plug-in boards that can be added to expand CO/STA capacity. Both
KSUs can generally support a 12x24 configuration for a total capacity of 28x50. The BKSU and
EKSU cabinets are installed using industry-standard blocks, jacks, and skinny wire cabling. This,
combined with the ability to program the system using a key terminal with a digital display,
reduces installation cost and maintenance requirements.
An optional 9600-baud Modem Unit (MODU) facilitates remote programming.
System Interface Boards
The STSe system can support the following types of interface boards:
CO card provides 4 loop start lines (LCOB)
Station card provides interface for 2 or 4 single line telephones or 8 digital key telephones
(SLIB or DTIB)
Primary Rate Interface Board (PRIB)
T-1 Interface Board (T1IB)
Primary Rate Interface Board (PRIB)
Voice Mail Interface Board (VMIB)
CO Circuitry
All CO interfaces are equipped with transformer barriers for system classification as a FCC fully
protected system. Each CO circuit supports rotary (out-pulse) dialing and loop supervision
(disconnect detection) under software control. The DTMF tone signals and system supervisory
tones can be generated in each keyset or on the main PCB. The STSe system uses a proprietary
tone plan for providing internal progress tones.
System Programming / Database
The system architecture allows system programmingchanges to be made without interrupting
state event software control of normal communications. Call processing continues while the
customer database is updated. All programming changes to the customer database
programming are made either from a digital terminal (Station 100) or from a terminal
connected to either an I/O port or remotely via the optional modem board.
Keyset / DSS Console
The STSe system features a digital telephone with 24 flexible buttons, 3 interactive soft keys, a
2 x 24 LCD display, and includes speakerphone capabilities. A 48-button DSS console is also
available. Each telephone can connect to an optional CTI "box". The optional CTI box provides
data connections and transmissions through an RS-232C connection on the phone.

Chapter 1 - Introduction
STARPLUS STSe - Installation Manual August 2005
Primary Rate Interface Board
The Primary Rate Interface Board (PRIB) provides one Primary Rate Interface circuit. Each circuit
contains 23 bearer and one data channel (23B+D). When a PRIB card is programmed into the
system, the system interprets all B channels as trunks. Thus, one PRIB which contains 23B+D
circuits provides 23 line appearances to the system. The PRIB card uses 24 time slots when
installed.
The PRIB must usually be used in conjunction with a Channel Service Unit (CSU). Connection is
made via a RJ-45 from the PRIB to the CSU.
The PRIB accepts two DTRU4 boards.
When ordering PRI lines from the telephone company, specify ESF framing and B8ZS line
coding. PRI only supports National ISDN 2 (NI-2). No other standards are supported.

Add-On Boards
Message Wait Unit
The Message Waiting Unit (MSGU48) provides a 90V message voltage to light the message
indicator on single line telephones.
One MSGU can be installed on each SLIB4/SLIBC (required if message wait indication is
needed).
Modem Unit
The Modem Unit (MODU) provides a communication interface for remote maintenance and
remote PC Admin.
The MODU allows the system to function as follows:
Operates at 9600 baud and installs in the BKSU.
Provides an asynchronous modem for access to the system database and fault reporting
features from a remote site.
May be connected to a pre-selected CO Line through the system-switching matrix.
The MODU port is independent of the standard RS-232C port, allowing system database access,
etc., without the need to interrupt the SMDR output.
Phase Lock Loop Unit
The Phase Lock Loop Unit (PLLU) provides clocking for T1, required if T1 card is installed.
The PLLU supplies a 32.768MHz clock to GSXD by either internal clock generator or clock
received from the trunk card (e.g. T1IB).
