MSI/PCI-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/PCI-Global Series, applications can be extended to incorporate live agent stations or third-party-add-on technology. Up to 16 analog station devices, such as local telephones, telesales agent headsets, modems, fax machines, or audio equipment can be connected to the SCbus and CT Bus in SCbus mode. 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/PCI-Global board.

The MSI/PCI-Global Series consists of an MSI/PCI80-GBL™ baseboard, which contains a digital signal processor (DSP) and an eight station interface daughterboard. An additional daughterboard (containing eight station interface circuits) can be added to the MSI/PCI80-GBL for a total of 16 stations. Preconfigured 16-port MSI/PCI160-GBL™ models can also be ordered.

The MSI/PCI-Global board is a PCI form factor board with a 32-bit bus that fits in a single PCI expansion slot.

Each MSI/PCI-Global station interface connects an application-selectable time slot on the SCbus to an analog station device. The 37-pin D-Sub female connector on the MSI/PCI-Global board enables easy connections to the available breakout box. For standard RJ-11 jack connections, Dialogic offers an optional SA/240 Station Adapter and a 37-pin cable.

An external Dialogic MSI/PCI-Global Power Module provides loop current (battery) and ring voltage to local telephones through the MSI/PCI-Global. The system can handle all stations going on- or off-hook simultaneously.

All MSI/PCI-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/PCI-Global defaults to a 33 percent duty cycle ring cadence and can ring 16 phones simultaneously.

Balanced lines ensure low noise and allow stations to be installed up to 5280 feet (1 mile) from the host PC. Built-in electrostatic discharge (ESD) protection lets agents insert and remove headset jacks, without damaging MSI/PCI-Global board circuits.

Application-programmable channel gain controls the volume for each channel and matches line impedance 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/PCI-Global board can be used to establish conferences between any of the time slots on the CT Bus/SCbus and the station devices connected to MSI/PCI-Global station modules. Call conferencing connects two to eight parties for up to 32 parties 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

Using the MSI/PCI-Global tone generation capabilities, an application can send alert tones to agents when an incoming call requires action.

The MSI/PCI-Global is fully compatible with all Dialogic and third-party products that use North-American µ-law or European A-law PCM (Pulse Code Modulation) coding schemes.

Configurations

Use the Dialogic MSI/PCI-Global to expand the capabilities of switching and station interface applications and to design economical cost-effective CT applications of any size. The MSI/PCI-Global board installs in PCI computers (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/PCI160-GBL boards can be used to service all 30 channels of an E-1 network.

You can use the MSI/PCI-Global board as a conference resource, independent of the onboard station interfaces. For example, an MSI/PCI-Global board added to your CT system can provide conferencing to PBXs lacking that capability.
MSI/PCI-Global stations can be independently assigned to any CT Bus/SCbus time slot, enabling station-connected agents or devices to serve as shared resources. Multiple MSI/PCI-Global boards can be installed in a single system, each sharing the same PC interrupt. The MSI/PCI-Global hardware permits up to 16 MSI/PCI-GBL boards in a single system. (System size limitations depend on the application and host processing power.) 

Software Support
The MSI/PCI-Global is supported by the Dialogic System Software and Software Development Kit (SDK) for Windows NT that contains a set of tools for developing complex multichannel applications. 

Functional Description

48 X 96 Call Center System

Each MSI daughterboard contains eight line interfaces and Dual Subscriber Line Audio processing Circuits (DSLACs) for COder/DECoder (CODEC) functions. Each line interface provides battery feed and ring to one station device. The line interface performs the 2 to 4 wire conversion that 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 CODECs convert inbound audio from analog to eight-bit digital audio signals, and outbound audio from digital to analog signals. The digital-to-analog gain of the CODEC is controlled separately for each station through the application. The DSLAC transmits and receives digital audio signals to and from 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 CT Bus/SCbus.

The crosspoint switch routes PCM data to and from the CT Bus/SCbus, any baseboard or daughterboard line interface, or DSP. A conference bridge feature of the MSI/PCI-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 CT Bus/SCbus or station interfaces.

The control microprocessor interprets and executes commands from the host PC and controls all operations of the MSI/PCI-Global board via a local control bus. Communications between this microprocessor and the host PC are through the shared RAM interface to the PCI bus. All operations are interrupt-driven to meet the demands of real-time systems. All MSI/PCI-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 board IDs. This feature eliminates the need to set confusing jumpers or DIP switches. More than one board can be set to ID 0.
