The phenomenal
growth in the Internet has been driven by a number of factors, one of
these being the elimination of the distance related usage charges found
with conventional communications. The cost of establishing a connection
and transferring information between two points is independent of the distance
between the two.
The V-SERVER iGATE is designed to assist
service providers in helping their small business customers realize
similar savings for voice/fax calls via Internet Telephony.
By combining a VoIP (Voice over IP) Gateway
with an IP access router, a single dialup Modem, ISDN, xDSL and/or Cable
Modem link from the local carrier’s POP (Point of Presence) can be used
to mix voice, data and fax traffic eliminating the cost of multiple access
circuits.
In addition, access to TEK DigiTel’s
Dynamic Dialing Administrator (DDA), H.323 support and intelligent call
routing allows the end-users to transparently use the lowest cost
voice/fax service on a call by call basis.
The low cost and ease-of-use features in
the V-SERVER iGATE enable the Service Providers to quickly deploy IP
based Voice/Fax services to their customers:
- Internet Service Provider’s (ISPs) and
Competitive Local Exchange Carriers (CLECs) can derive additional
monthly revenue from their customer base via provisioning local PSTN
voice circuits, enabling intercompany toll free calling and through
partnerships to route calls to Internet Long Distance Telephony
Providers.
- Internet Telephony Service Providers (ITSPs)
can form alliances with local access providers to use the V-SERVER
iGATE to simplify the re-routing of specific long distance calls to
their PSTN gateways. The V-SERVER iGATE can be viewed as an
intelligent "Internet Re-dialer" directing a subset of calls
to the ITSP network.
Overview
The V-SERVER iGATE is
designed to allow conventional telephony devices such as analog phones,
key systems and PBXs to be connected via the Internet. In basic operation,
it performs a gateway function converting analog voice traffic to a
packet IP based information flow enabling transport over IP (Internet
Protocol) based networks. In addition, fax machines connected to the same
voice ports will be automatically detected and their output will also be
converted to IP.
This functionality allows users with phones
or fax machines connected to the V-SERVER iGATE to
place calls across the Internet to other V-SERVER users
or to any other standards based VoIP (Voice over IP) Gateway or PC client.
When used in Gateway mode, the V-SERVER iGATE can be
connected to an existing Router or Cable/ xDSL modem via the units
Ethernet port.
In addition to the Gateway function, the V-SERVER
iGATE incorporates standards based IP routing functionality
allowing it to be connected directly to the Internet access link provided
by the local ISP (Internet Service Provider). An integral ISDN BRI
interface (U or S/T versions available) provides direct connectivity or
existing Dialup Modems can be connected to the V-SERVER’s
serial port. The serial port also supports V.35 Sync connection.
Features
Multi-Service Support
Configuration flexibility allows the V-SERVER iGATE to
be used in all forms of Internet Access configurations including
conventional ISDN and Analog modem dial-up connections, dedicated links
as well as newer xDSL and cable modem environments. Service Providers can
use the V-SERVER as a ubiquitous VoIP deployment
tool.
Standards based VoIP Support
The V-SERVER iGATE supports
all of the primary standard voice encoding schemes including ITU
Recommendations G. 723, G. 729a, G. 711 and G.723.1. This focus on
standards ensures the device will be able to connect attached phone users
to a wide variety of third party VoIP devices. In addition, support for
the latest version of H.323 ensures that connections can be made to other
VoIP entities using H.323 Gatekeepers.
Analog Phone Support
Both FXS (Foreign Exchange Station) and FXO (Foreign Exchange Office)
connections can be supported by the V-SERVER iGATE allowing
connections to be made to analog phones, the PSTN directly and to both
subscriber and trunk sides of PBXs and Key Systems. There are no
restrictions on calls between any combination of these ports.
Fax Support
Fax Detection and Demodulation enables the V-SERVER
iGATE to transport sessions between standard Group 2 and 3 Fax
Machines. By identifying incoming fax calls and demodulating the fax modem
signal, the fax "data" stream is transported through the IP
network in its native 4,800-14.4 Kbps format and regenerated by the voice
part on the other side. This eliminates the excessive bandwidth overhead
normally found with fax connections. The V-SERVER iGATE also supports
the T.38 fax protocol and provide T.38 interoperability with other
vendors' products, such as Cisco and Audiocode.
Routing Support
Full standards based IP base datagram
routing between the serial, ISDN BRI and Ethernet port is supported. Both
Asynchronous and Synchronous PPP (Point-to-Point Protocol) are supported
on the WAN link with Multilink PPP support for the ISDN BRI. DHCP (Dynamic
Host Configuration Protocol) client support enables the V-SERVER to
receive it’s network IP address from the ISP.
IP Address Sharing
When configured as a router, the V-SERVER can
support multiple PC clients and voice services even though only a single
IP address is provided by the carrier. Network Address Translation (NAT)
functionality allows the multiple IP addresses defined for the PC users
connected to the V-SERVER Ethernet port to be
re-mapped to appear as a single IP user to the service provider. In
addition, Voice/Fax calls coming into the device from the Internet will be
directed to the units voice ports. This eliminates the need for a costly
second IP address from the service provider.

Dynamic Address Resolution Selection
The V-SERVER, in the process of trying to match the
phone number entered by the user to the IP address of the remote VoIP
port, supports three modes of address resolution: Static, H.323 Gatekeeper
and TEKs Dynamic Dialing Administrator (DDA). As calls are placed on
the V-SERVER voice ports, the unit will attempt to
find a destination using all three of these mechanisms:
Static - Direct Phone number to IP address
mappings can be stored in the V-SERVER's
configuration memory enabling calls to be placed without intervention
by an external Gate Keeper. This mode of operation also provides
fast call set-ups and enables quick connection to PC telephony applications
like Microsoft NetMeeting.
H.323 Gatekeeper - This
allows the V-SERVER to request help in matching
the input phone number to an IP address using any external H.323 based
Gatekeeper on the network. In using this facility, all added
functionality provided by the Gatekeeper (i.e. call billing, call
authorization, calling card access, etc.) is enabled for the call.
Dynamic Dialing Administrator (DDA)
- This enhanced gatekeeper functionality provides a hybrid of the static
and H.323 mode delivering the better qualities of each. Rather than
delivering Phone Number to IP address mappings on a request by request
basis, the central DDA server automatically takes responsibility for
maintaining map ping tables in each of the V-SERVERs. Each V-SERVER upon
starting up or making any changes to its IP address, updates the DDA
server which in turn keeps all V-SERVERs up to date with the phone
number/IP address mappings of all (or just a subset) the other V-SERVERs
in the network. Phone calls are made in a similar fashion as the static
mode as a connection to a Gatekeeper is not required.
Remote V-SERVER Wake-up
Connecting between VoIP clients in a dedicated environment is a fairly
straight forward process. However when remote VoIP clients access the
Internet via "dial on demand" ISDN links the requirement that
the remote user be on line to receive calls means that VoIP connectivity
is not guaranteed.
To eliminate this issue, the V-SERVER
has the unique ability to "wake up" disconnected remote
users be triggering their V-SERVER to dial the ISP
to receive the call. In addition to the IP address, of the remote user,
the local V-SERVER maintains the phone number of the
remote V-SERVER and upon not being able to reach it
will place a conventional phone call to the remote device. This
unanswered "toll free" call will trigger the remote V-SERVER
to dial into the Internet to allow the VoIP call to be placed. This
mechanism enables dial-up Internet users to receive the same Voice/Fax
connectivity as dedicated users.
V-Express
Every V-SERVER comes bundled with a copy of V-Express,
a graphical Windows configuration tool designed for the non technical user
to guide them through managing the node. V-Express supports
monitoring, statistics, status, alarms, and control functions of local or
remote V-SERVERs as well as updating the software.
A special Fast Setup Wizard mode steps the new user through the
basic configuration prompting them for the values needed in a simple
configuration. V-Express can connect to the V-SERVER
locally via the Ethernet or Serial port or even across the
Internet.

Management
In addition to the V-Express Client, the V-SERVER
can be configured/monitored via a Telnet session. New firmware for
the V-SERVER iGATE can be automatically downloaded to
the unit from the DDA. The V -SERVER is also fully SNMP manageable
under 3rd Party UNIX and Windows NT SNMP platforms.
