Meridian 1 TAPI 2.0
Server
Description:
Many businesses are
selecting Microsoft Windows as the platform for deploying business
critical applications. The Microsoft Telephony Applications
Programming Interface (TAPI) allows Windows application programs to
control telephony functions. This includes such basic functions as
establishing, answering, and terminating calls. It also includes other
functions such as hold, transfer, and conference.
TAPI 2.0 is a new version of TAPI which is bundled with Windows NT
version 4.0. It brings the full functionality of TAPI version 1.4 from
the Microsoft Windows 95 to Windows NT as a Win32 service. All core
TAPI 2.0 components are Win32-based, with full support for RISC-based
processors, symmetrical multiprocessing, multithreaded applications,
and preemptive multitasking. Support for call center functions is
enhanced, with modeling of queues, ACD agent controls, associating
data with calls, controlling call treatments, controlling message
waiting lights, and centralized event timing. TAPI 2.0 on Windows NT
introduces sophisticated third-party call control functions for
monitoring station set status, supporting predictive dialing
applications, ACD queue events, call routing, and network security.
The availability of features depends upon the underlying telephony
'service provider' and telephony system connection.
Nortel's Meridian 1 TAPI 2.0 Server is a service provider that marries
TAPI 2.0 with the Meridian 1 via Meridian Link with comprehensive
support of Meridian Link Release 5 call processing features. Included
are Meridian Call Center agent functions such as login,
ready/not-ready, and agent DN control, along with support for
FastTransfer for predictive dialing applications, and
applications-based routing to allow TAPI applications to route calls
based on network information such as ANI, DNIS, etc.
The Windows NT server, running the Meridian 1 TAPI Server, connects to
a Meridian 1 via a Meridian Link Module using TCP/IP over Ethernet.
The server contains the Meridian 1 TAPI Server service provider and
TAPI 2.0 on Windows NT software.
IVR Integration
Nortel's Meridian 1 TAPI 2.0 Server provides an "open interface" for
integration with IVR systems for caller-entered information. It uses a
variable sized field which can contain information about a call (such
as IVR digits) that will be passed along with the call and made
visible to all TAPI applications monitoring the call. A new function,
lineSetCallData, has been added which allows the application which
owns this call to also set this data.
An IVR unit can be configured to initially interact with callers to
understand who they are and in what services they are interested. The
Meridian 1 TAPI 2.0 Server Open IVR interface then allows this
information to be passed to TAPI 2.0 applications via the TAPI 2.0
interface when the call is transferred to an agent or other user on
the Meridian 1 system.
Networking
The Meridian 1 TAPI 2.0 Server also passes information (up to 2048
bytes) collected at an IVR unit (via the Open IVR interface) or
provided by a TAPI application with a call when the call is
transferred to another local user or a user on Meridian 1 system. When
another Meridian 1 location is involved, the information is
transferred across a WAN connection between Meridian 1 TAPI 2.0
Servers. This method relies on Meridian 1's Call ID and Network Call
ID features to associate the particular call-related information with
particular calls.
Applications can provide screen pops based on information obtained
from a caller or a data base at one location when the call arrives at
another location.
Microsoft Remote Service Provider
Microsoft plans to introduce Remote Service Provider software that
will allow Windows NT to function as a telephony server. When
functioning as a telephony server, Windows NT will support TAPI 2.0 -
compliant applications running locally or on network-connected Windows
NT or Windows 95 clients. This distributed client/server application
environment logically integrates the telephone on a user's desktop
with an application in network connected PCs. The telephone is
physically connected to the switch with integration to the user's
desktop provided via the switch-server interface. In this
configuration, users' desktops do not require any special telephones,
connectors, PC circuit packs, or new wiring. The logical configuration
is diagrammed below.
TAPI 2.0 for Windows NT is provided by Microsoft. TAPI Server Service
Provider is provided by Nortel. There are two version of the TAPI
Server available. Meridian 1 TAPI Server is the low cost standard
package. Meridian 1 TAPI Server with IVR integration and Networking is
our premium package that includes the standard package in addition to
the ability to integrate with any third party IVR for user enter
digits and the ability to share screen data across multiple networked
switches.
Summary
TAPI 2.0 is Microsoft's newest version of TAPI released with Windows
NT Version 4.0 and enhances support for many call center features.
TAPI 2.0 is the ideal platform for CTI enabling the Win32 applications
version of TAPI
Microsoft plans software to enable Windows NT to act as a telephony
server that will simplify deployment for desktop applications
The Meridian 1 TAPI 2.0 Server provides:
- comprehensive support of Meridian 1 Teleset and Agent functions
- an open interface for integration with IVR systems
- coordinated screen transfer (local and remote)
- sophisticated applications-based call routing
TAPI 2.0 Client-Server Model simplifies deployment for desktop
applications.
Server Requirements
A minimum release of Windows NT 4.0 is required for the TAPI server.
The TAPI SP is designed to be hardware independent. Therefore, all
that is required is a system which runs the Windows NT 4.0 server
operating system.
The minimum hardware level of the server PC is as follows:
- A 486/66 MHz PC, EISA or ISA Bu
- 3.5" Disk Drive
- CD ROM
- 16 Megabytes of RAM (This may increase to a minimum of 32
Megabytes.)
- 2 Megabytes of free disk space for TAPI SP
- Ethernet card (dedicated LAN to Meridian 1)
- LAN card (for client PC LAN connection)
- Mouse
- VGA or SVGA Display
