CTI Computer Telephony Integration
This section of our technical library presents information and documentation relating to Computer Telephony and Computer Telephony Integration software and products.
Computer Telephony Integration CTI software is a rich set of phone software library routines that enable application programs to control your phone system.
This comprehensive CTI software lets you increase employee productivity, enhance customer service and reduce costs by combining the capabilities of our PACER phone system with the custom functionality of your Windows, Unix or Web applications.
Data collected by your phone ACD (Automatic Call Distribution) or IVR (Interactive Voice Response) systems can be passed to your existing PC, Unix or Web applications through our phone software.
The PACER predictive dialer can automatically call your customers and pass only connected calls to your agents. With our computer telephony software, your telephone and computer work together to provide cost-saving benefits.

NAT (Network Address Translation):
An Internet standard
that enables a
to use one set of
for internal traffic and a second set of addresses for
external traffic. A NAT box located where the LAN
meets the Internet makes all necessary IP address
translations. NAT serves three main purposes: 1)
Provides a type of
by hiding internal IP addresses. 2) Enables a company
to use more internal IP addresses. Since they're used
internally only, there's no possibility of conflict with
IP addresses used by other companies and organizations.
3) Allows a company to combine multiple ISDN connections
into a single Internet connection.
NIC (Network Interface Card):
Connects a device to a LAN, usually in the form of an
Node: Point of
connection in a network, means a unit is polled. In a
LAN it is a device on a ring and in a packet switched
network its one of many packet switches that form the
NT: New Technology.
ODBC (Open Data Base
Connectivity): Microsoft standard that allows
disparate databases to be accessed by a common
OSFP (Open Short Path First): A
networks based on the shortest path first or link-state
use link-state algorithms to send routing
information to all nodes in an internetwork by
calculating the shortest path to each node based on a
topography of the Internet constructed by each node.
Each router sends that portion of the routing table
(keeps track of routes to particular network
destinations) that describes the state of its own links,
and it also sends the complete routing structure
(topography). The advantage of shortest path first
algorithms is that they results in smaller more frequent
updates everywhere. They converge quickly, thus
preventing such problems as routing loops and
Count-to-Infinity (when routers continuously increment
to a particular network). This makes for a stable
network. The disadvantage of shortest path first
algorithms is that they require a lot of CPU power and
memory. In the end, the advantages out weigh the
disadvantages. OSPF Version 2
is defined in
It is rapidly replacing RIP on the Internet.
OSI (Open System Interconnection):
worldwide communications that defines a networking
framework for implementing
seven layers. Control is passed from one layer to the
next, starting at the application layer in one station,
proceeding to the bottom layer, over the
channel to the
next station and back up the hierarchy. Most of the
functionality in the OSI model exists in all
communications systems, although two or three OSI layers
may be incorporated into one.
PBX: Private Branch
PC-PBX: Is a down sized
version of the phone company’s larger central switching
PCI (Peripheral Component
Interconnect): 32 bit local bus @ 132 mbs vs. 5
for an ISA.
PDF (Portable Document
Format): Documents viewed and created by Adobe’s
Acrobat Reader to standardize Internet-based documents.
Network access point for data entry or exit. Also an
POTS (Plain Old Telephone
System): Is a step below a PSTN as POTS just supplies simple
single line phone systems with NO features what so ever.
Protocol over Ethernet): PPPoE relies on two widely accepted standards:
is a specification for connecting the users on an
Ethernet to the
a common broadband medium, such as a single
wireless device or cable
modem. All the
users over the Ethernet share a common connection, so
the Ethernet principles supporting multiple users in a
LAN combine with
the principles of PPP, which apply to
PRI (Prime Rate Interface):
In North America 1,544,000 bits/second and made into as
many as 24 phone calls.
PSTN (Public Switched Telephone Network):
Any phone system of local, long distance and
international phone companies.
Virtual Circuit): A
virtual circuit that is permanently
available. The only difference between a PVC and a
switched virtual circuit (SVC) is that an SVC must
be reestablished each time data is to be sent. Once the
data has been sent, the SVC disappears. PVCs are more
efficient for connections between
hosts that communicate frequently. PVCs play a
central role in
Frame Relay networks. They're also supported in some
other types of networks, such as
