* With optional SA/240 Station Adapter and 50-pin cable
MSI-Global Series Modular Station Interface products incorporate
a variety of analog devices, such as local 2500-type touchtone
telephones, modems, and fax machines, into CT systems that
are based on the open, industry-standard SCbus architecture.
With the MSI-Global Series, applications can be extended
to incorporate live agent stations or third-party-add-on technology.
Up to 24 analog station devices, such as local telephones,
telesales agent headsets, modems, fax machines, or audio equipment
can be connected to the SCbus. A conferencing feature enables
applications to establish conferences between any of the time
slots on the SCbus and the station devices connected to the
MSI-Global board.
The MSI-Global Series consists of an MSI/80-GBL baseboard,
which contains a digital signal processor (DSP) and eight
station interface circuits. Up to two MSI/80-GBL daughterboard
modules (each daughter board contains eight station interface
circuits) can be added to the baseboard for a total of 24
ports. Preconfigured 16-port MSI/160-GBL and 24-port MSI/240-GBL
models can also be ordered.
The MSI-Global board is an AT form factor board with a 16-bit
bus that fits in a single AT (ISA) expansion slot (even with
station daughterboards installed).
Each MSI-Global station interface connects an application-selectable
time slot on the SCbus to an analog station device. The RJ-21X
telephone interface on the MSI-Global board enables easy connections
to breakout boxes or punchdown blocks. For standard RJ-11
jack connections, an optional SA/240 Station Adapter and a
50-pin cable is available.
An external MSI-Global Power Module provides loop current
(battery) to local telephones through the MSI-Global. The
system can handle multiple stations going on- or off-hook
simultaneously.
All MSI-Global models are capable of providing a power ring
that generates the AC voltage needed to ring standard 2500-type
telephones. This power ring capability is contained completely
onboard within the slot. No additional external circuitry
is required. The MSI-Global defaults to a 33 percent duty
cycle ring cadence and can ring 24 phones simultaneously.
Balanced lines ensure low noise and allow stations to be
installed up to 5,280 feet (1 mile) from the host PC. Built-in
electrostatic discharge (ESD) protection lets agents insert
and remove headset jacks, without damaging MSI-Global board
circuits.
Application-programmable channel gain controls the volume
for each channel and matches line levels from country-specific
telephone sets and devices.
Station status event detection collects call traffic statistics
and enables cost-effective management of call setup/call termination.
The MSI-Global board can be used to establish conferences
between any of the time slots on the SCbus and the station
devices connected to MSI-Global station modules. Call conferencing
connects two to eight parties for up to 32 channels of total
conferencing.
The following features are provided:
- Two- to eight-party conferencing
- Up to 32 conferencing resources, total
- Conferences of any combination of agents and network channels
- Hidden training for smooth entry of new conferees, without
disruptive training noise
- Supervisory monitoring of agents, without disrupting the
conversation
- Coaching feature that allows supervisors to speak to agents
without the customer listening to the supervisor; customer
can hear the agent at all times (no switching)
- Programmable channel gain to optimize volume levels for
station devices
- Programmable cadence allows you to select and set ring
cadence options (UNIX and Windows NT only)
Full digital conferencing capabilities allow a call center
supervisor to participate in a transaction or to monitor a
transaction in listen-only mode. The MSI-Global board's hidden
training algorithms permit conferees to smoothly enter and
exit a conference without hearing bothersome noises. By using
the SCbus' broadcast capability, a virtually unlimited number
of parties can monitor a conference.
Using the MSI-Global tone generation capabilities, an application
can send alert tones to agents when an incoming call requires
action.
The MSI-Global is fully compatible with all Intel®
Dialogic® boards and third-party products that
use North-American µ-law or European A-law PCM (Pulse Code
Modulation) coding schemes.
Configurations
Use the MSI-Global to expand the capabilities of switching
and station interface applications and to design economical
cost-effective CT applications of any size. The MSI-Global
board installs in IBM PC AT (ISA bus) and compatible computers
(386™, 486™, or Pentium® processor-based PC platforms).
In a typical telemarketing application, a voice board or
other resource board dials outbound numbers. When the system
detects a called party going off-hook, the call is passed
to a local operator through an available channel.
For inbound applications, calls that are not handled by
voice automation can be passed directly to a live agent. The
agent can be alerted to the incoming call by a power ring
or zip tone.
Two MSI/160-GBL boards can be used to service all 30 channels
of an E-1 network.
You can use the MSI-Global board as a conference resource,
independent of the onboard station interfaces. For example,
an MSI-Global board added to your CT system can provide conferencing
to PBXs lacking that capability.
MSI-Global stations can be independently assigned to any
SCbus time slot, enabling station-connected agents or devices
to serve as shared resources. Multiple MSI-Global boards can
be installed in a single system, each sharing the same PC
interrupt. For example, two MSI/240-GBL boards can be cabled
to four D/240SC-T1 voice and T-1 boards, via the SCbus, creating
a 48-agent-by-96-trunk call center. Applications can exploit
the switching ability of the SCbus to create economical agent-to-call
ratios. The MSI-Global hardware permits up to 16 MSI/240-GBL
boards in a single system. (System size limitations depend
on the application and host processing power.)
48 X 96 Call Center System
NOTE: The MSI-Global must not be connected directly to
the public telephone network. Use only with local headsets
and telephones
Software Support
The MSI-Global is supported by System Software and Software
Development Kits (SDKs) for UNIX and Windows NT. These packages
contain a set of tools for developing complex multichannel
applications.
Functional Description
The signals from each station device (phone, headsets, etc.)
enter the line circuitry on the MSI-Global board through an
ESD filter, and are applied to a line interface on an MSI-Global
baseboard or daughterboard. This filter protects the MSI-Global
board against conditions, such as electromagnetic interference
(EMI) and voltage transients on the station device lines —
including electrostatic discharge and transients generated
by plugging in or removing operator headsets.
Each MSI baseboard or daughterboard contains eight line
interfaces and Dual Subscriber Line Audioprocessing Circuits
(DSLACs) for COder/DECoder (CODEC) functions. Each line interface
provides loop start current to one station device. Loop start
current to station devices (-24 VDC) can be turned on or off
individually by the application. The line interface performs
the 2 to 4 wire conversion which separates the inbound signal
into an audio signal sent to the DSLAC. An on-hook/off-hook
signal that is transmitted by the onboard control microprocessor
via the input/output buffer is sent by the host PC AT bus
to the application program.
The CODEC converts inbound audio from analog to eight-bit
digital audio signals, and outbound audio from digital to
analog signals. The gain of the CODEC is controlled separately
for each station device through the application. The DSLAC
then transmits the digital audio signals to the crosspoint
switch conferencing circuit.
The crosspoint switch receives digitized audio signals from
the DSLAC, and channel switching/connection signaling from
the onboard control microprocessor for each channel. The crosspoint
switch acts as the traffic coordinator to route PCM audio
data from the local station interfaces to a DSP and the SCbus.
The crosspoint switch routes PCM data to and from the SCbus,
any baseboard or daughterboard line interface, or DSP. A conference
bridge feature of the MSI-Global board enables a user or an
application to establish conferences (connect two or more
parties) between any of the time slots present on the SCbus
or station interfaces.
The control microprocessor interprets and executes commands
from the host PC and controls all operations of the MSI-Global
board via a local control bus. Communications between this
microprocessor and the host PC are through the shared RAM
interface to the PC ISA bus. All operations are interrupt-driven
to meet the demands of real-time systems. All MSI-Global boards
installed in the PC share the same interrupt line. When the
system is initialized, firmware to control all board operations
is downloaded from the host PC to the onboard RAM. This downloadable
firmware gives the board all of its intelligence and enables
easy feature enhancement.
The Board Locator Technology circuit operates in conjunction
with a rotary switch to determine and set nonconflicting slot
and IRQ interrupt-level parameters. This feature eliminates
the need to set confusing jumpers or DIP switches.
