NETWORKS NEXUS VoIP VOICE/FAX IP GATEWAY
What's it do?
NexusVoIP is specifically targeted at businesses
looking to reduce toll charges between frequently called sites.
NexusVoIP is a point-to-point IP gateway that integrates seamlessly
into your data network and operates alongside existing PBXs, or
other phone equipment to simply extend voice capabilities to remote
locations. It is designed to help you maximize investments you've
already made in your data and voice network infrastructure.
A NexusVoIP network can be as small as two offices or as large as
hundreds of offices. Each office installs and configures a NexusVoIP
on their network and connects it to their existing phone equipment
to begin placing calls or sending faxes to the other offices on
the VoIP network.
The NexusVoIP supports 14.4Kbps real-time faxing over an IP network.
For businesses with a heavy fax load between offices, reducing faxing
costs may be the primary use for the NexusVoIP network.
Create off-premise extensions
Extend the reach of your PBX into home office locations. Simply
connect a NexusVoIP gateway to the PBX at the corporate office,
and another NexusVoIP gateway at the remote office. Now, anyone
can place calls to the remote office by simply dialing an extension
number. To extend your PBX to a building across the street, utilize
a wireless bridge to connect the two networks. Now, you have voice
and data connectivity without having to lay cables or paying monthly
charges for dedicated lines.
Telecommuters or customers off the IP network can make free long
distance calls by dialing into a local NexusVoIP and placing toll-free
calls to any location on the VoIP network. You can even have a NexusVoIP
at a remote site dial a local phone number for a free person-to-person
long distance call.
Replace Expensive Tie Lines
A corporation that utilizes Tie lines to connect branch office PBXs
to the corporate PBX can now use the company's IP-based Wide Area
Network to complete the call.

Save thousands of dollars
NexusVoIP can save your company substantial amounts in long distance
charges. Even if your company uses one of the most inexpensive calling
plans, a NexusVoIP network can quickly return your investment and
begin paying you back.
With NexusVoIP you avoid the hassle and expense of replacing your
existing routers, WAN connections or phone systems required by other
VoIP solutions. NexusVoIP simply plugs into your Ethernet network.
Neither your phone service or network is placed at risk. Minimum

Award-winning voice quality
With NexusVoIP, you'll experience consistent toll-quality voice
connections. Using the Perceptual Speech Quality Measurement £¨PSQM
£©Internet Telephony magazine found that
NexusVoIP delivered exceptional voice quality. In fact, NexusVoIP
outranked the competition.
NexusVoIP utilizes the H.323 protocol providing complete interoperability
among other H.323 telephony solutions.
Bandwidth is used only when someone is speaking. The silence suppression/Voice
Activity Detection (VAD) feature is an option that frees unused
call bandwidth for data traffic. This is significant, since callers
are usually silent for 60 percent of a call. When using silence
suppression, NexusVoIP also offers Comfort Noise Generation (CNG)
at the receiving end so the user knows the line has not dropped.
In addition, NexusVoIP supports voice compression standards like
G.729 (8:1) and G.723 (10:1). These standards help minimize the
bandwidth required for voice. G.723, for instance, is the maximum
compression rate and requires only 5.3Kbps (plus an added 7.7Kbps
for IP overhead). Even at maximum compression, your VoIP solution
will still provide toll-quality voice.
Uniform Dialing Plan
NexusVoIP utilizes Asce Networks' Uniform Dialing Plan (MUDP), with
a centralized database, that is consistent with the E.164 (PSTN)
standard numbering plan. This allows for single stage dialing and
ensures that users will not require additional training to make
VoIP calls. The centralized database allows the phone books of all
VoIP gateways on the network to be configured from a single predefined
Advanced speech technologies
NexusVoIP supports the Differentiated Services (DiffServ) Quality
of Service (QoS) protocol which sets priorities for voice and fax
traffic and allows transparent delivery. DiffServ helps move time-sensitive
voice traffic across even low-bandwidth WAN connections, like 56K
and ISDN, with the priority and quality required by voice. Other
features such as adaptive echo cancellation, forward error correction,
bad frame interpolation, tunable latency and dynamic jitter buffers,
further enhance voice quality.
Complete support for multiple
For maximum investment protection, the NexusVoIP two, four and eight-port
models accommodate changing communication needs by providing an
FXS, FXO and E&M interface for each port. With the right interface,
the NexusVoIP connects directly to phones, fax machines, key phone
systems or a PBX. With this range of support, you can connect a
phone directly to a port today, and tomorrow connect your PBX trunk.
A single port NexusVoIP supports either FXS or FXO interfaces depending
on model while T1/E1models connect directly to a PBX or PSTN line.
NexusVoIP is easily managed locally or remotely by the central office
with a web browser*, Windows 95/98/Me/2000, Windows NT software,
tftp, Telnet or SNMP. Asce Networks also includes its own SNMP management
software called NexusVoIP Manager which provides central site configuration,
management and call monitoring for all NexusVoIP gateways on the
network. It utilizes a Windows interface that makes it easy to view
events like usage tracking, live use reporting, call history, and
voice quality statistics. Call detail records may also be transferred
to third-party billing software.
Access voice mail
Dual Tone Multifrequency (DTMF) support allows users to access their
voice mail over the VoIP network.
Optional H.323 IP Telephony
The NexusVoIP Gatekeeper is a complementary product to the NexusVoIP
Voice over IP gateway. The turnkey hardware and software solution
provides corporate enterprise network managers and Intranet managers
the power to define and control how H.323 voice traffic is managed
over IP networks. With the NexusVoIP Gatekeeper, network managers
have the ability to configure, monitor and manage the activity of
registered network end points. In addition, managers can set policies
and control network resources, such as bandwidth usage, to ensure
optimal implementation. For more information on the NexusVoIP Gatekeeper,

No user training
Placing calls with the NexusVoIP is like using your existing phone
system. No end-user training is required. Users can begin making
calls immediately with a published VoIP phone list and simple calling
Your NexusVoIP network uses the same security as your data network.
Therefore, if you have strong data security, your voice security
will be strong as well. NexusVoIP also allows administrators to
place it behind a compliant firewall to further enhance security.
In addition, NexusVoIP provides inter-operability with Virtual Private
Network (VPN) products. And, when using NexusVoIP in proprietary
mode, proprietary protocols make it difficult for hackers to access
the VoIP network.
The Asce Networks' NexusVoIP provides toll-free voice and fax communications
over the Internet or Intranet.
By integrating voice and fax into your existing data network, you
can realize substantial savings on inter-office long distance toll
The NexusVoIP family is available in one, two, four, eight and 24/30
port models. All NexusVoIP products connect directly to
phones, fax machines, key systems, or a PBX to provide real-time,
toll-quality voice connections to any office on your VoIP network.
