A hybrid telecommunication
system includes a switched network which
transfers information across the Internet to
provide multi-routed and multidimensional
callback processing. The hybrid network includes
one or more switched networks coupled to one or
more packet transmission networks, and a call
router coupled to the switched communication
network and the packet transmission network to
route information to the appropriate switched
telephony device or Internet device address. A
computer with an attached display communicates
with the packet transmission network. The
computer is used to initiate remote management of
the hybrid network, including tests of the hybrid
network. The tests include circuit analysis such
as selecting signaling states which could be loop
start, ground start, or detecting signals such as
dual tone multifrequency, multifrequency or
dialpulse. The hybrid network includes support
for an operator to monitor the management of the
hybrid network, and an expert system to regulate
the Quality of Service of the hybrid
telecommunication system.
Field Of The Invention
The present invention relates to the
integration of the Internet with
telephony systems, and more specifically,
to a system, method and article of
manufacture for using the Internet as the
communication backbone of a communication
system architecture while maintaining a
rich array of call processing features.
Background of the Invention
The Internet has increasingly become the
communication network of choice for the
consumer e-mail marketplace. Recently,
software companies have begun to
investigate the transfer of telephone
calls across the Internet. However, the
system features that users demand of
normal call processing are considered
essential for call processing the
Internet. Today, those features are not
available on the Internet. Thus, a system
is required that connects the
communication network including telephony
capability with the Internet to
facilitate callback processing.
Callback scenarios for reserving calls
over existing telephony networks have
been available for some time. Examples of
such service are CSI
Callback, Rumilla Telecommunication for
international callback and
SummitLink which provides international
callback offering distribution,
wholesaling and rebilling features. The
Internet provides a website entitled,
"Callback on the Net" which
purports to "collect all available
information on callback services."
This information was accumulated by doing
a Yahoo search utilizing the search term
"callback".
International callback as provided by the
prior art system refers to a user being
able to dial a number to connect to a
switch overseas. The caller allows the
phone to ring twice and hangs up. The
switch then utilizes the ANI and/or
called number information to query a
database of profile information stored on
the switch to determine billing and other
information on the caller. Then, the
switch initiates a call to the caller and
when the caller goes offhook, the switch
provides a dialtone allowing the caller
to access any number available to the
switch. In this way, international or
other long distance callers can obtain
low cost long distance services so long
as they are pre-registered for the
service. This service still requires the
caller to be responsible for all of the
overhead associated with initiating call
processing, requires a caller to learn
the protocol of interfacing with the
switch, does not provide reservation of
such services such as conferencing, and
it does not allow operator assistance on
the calls.
Recently, AT & T has announced a
service very similar to conferenceMCI
(MCI's Operator Call-in Conference Call
capability). This service termed
"On-Line TeleConference"
capability allows teleconference
customers to use an on-line interface to
allow customers to pre-arrange an AT
& T
TeleConference call through the World
Wide Web. However, while conference call
definition of a number for each
participate to call into to join the
conference is provided, "all voice
connections are established over the
existing telephone network" and
require all parties to contact a common
number to establish the conference call
(AT & T TeleConference
Service: On-Line Trial Information,
2/7/97).
While this new AT & T service is
moving in the direction that the subject
invention has already arrived at, it does
not provide integration of voice over the
Internet with existing network services,
nor does it provide any mention of a
callback architecture which allows a
calling party to prearrange for a network
service to contact one or more parties
and effectively eliminate the need for
any manual intervention. Moreover, it
does not provide an operator on an
exception basis for Internet telephony
operations. Thus, a true union of the
Internet and existing telephony networks
is not provided.
"Callback" is a telephony term
utilized by remote test systems in
reference to accessing and testing
customer's voice and data circuits which
traverse through a Digital Cross-Connect
System (DXC). When a callback feature is
selected, the remote test system bridges
a local phone line to a customer's DSO
circuit. If the circuit under test is an
analog circuit, the remote tester
performs monitoring. If the circuit under
test is a voice circuit, the remote
tester performs voice testing which
includes selecting appropriate signaling
states for callback to the customer's
phone over the circuit under test by the
remote test system. The callback feature
enables the remote tester to enter a
phone number to a co-located phone
residing at the remote tester's location.
The remote test system has local phone
lines attached to an internal card. The
purpose of the phone lines are to allow
the test system to place outbound calls.
After a remote user enters a number,
which includes an area code or their
co-located phone, the remote test system
selects one of the local phone lines,
goes off hood, and upon detecting dial
tone from the local telco central office
will dial pulse or DTMF the entered phone
number. The remote tester's phone
receives the call from the remote test
system, goes off hook, and then the call
from the remote test system to the remote
tester is considered complete.
The remote tester can then either monitor
the audible quality or initiate a call to
the voice circuit customer's phone by
selecting the appropriate signaling state
for the circuit under test. Once the
appropriate signaling state for the
customer is selected, the channel bank
card or PBX detects the incoming call and
converts it to ring cycle to the
customer's phone.
This action initiates a ringing condition
to the customer's phone. Upon the
customer answering the phone, the remote
tester verbally communicates with the
customer over the customer's circuit
under test.
This testing is routinely performed for
circuit assurance verification testing.
The remote test system has a limit of
outbound calls that can be completed.
This limit is dependent on the number of
phone lines that can be supported by the
test system's interface. There are also
monthly access charges by the telephone
company for each local line terminating
into the test system.
Summary of the Invention
According to a broad aspect of a
preferred embodiment of the invention,
telephone calls, data and other
multimedia information are routed through
a hybrid network including a switched
network which transfers information

multirouted and multidimensional callback
processing. The hybrid network includes
one or more switched networks coupled to
one or more packet transmission networks
that also couple a call router to the
switched communication network and the
packet transmission network to route
information to the appropriate switched
telephony device or internet device
address. A computer with an attached
display communicates with the packet
transmission network, the computer is
used to initiate remote management of the
hybrid network, including tests of the
hybrid network which include circuit
analysis such as selecting signaling
states which could be loop start, ground
start, dual tone multifrequency detection
or removing a line from service. The
hybrid network includes support for an
operator to monitor the management of the
mybrid network, and an expert system to
regulate the Quality of Service of the
hybrid telecommunication system.
