NetVanta 644
VoIP Media Gateway
The ADTRAN NetVanta 644 is a VoIP media
gateway designed to interface between
TDM and IP networks allowing connection
of legacy telephone and PBX systems to
IP Networks. The NetVanta 644 is also ideal
as a PSTN gateway providing IP conversion
for newer PBXs, like the NetVanta Unified
Communications Enterprise Communication
Server. Utilizing the ADTRAN AOS, the
NetVanta 644 offers simple management
and administration.
Superior Performance
The NetVanta 644 is designed to support
120 simultaneous calls and not miss a beat.
Interfaces include four T1/E1 ports as well as
two 10/100/1000 Ethernet ports providing the
flexibility for multiple deployment scenarios.
Media Gateway
The NetVanta 644 utilizes SIP and MGCP for
VoIP applications, providing interoperability
with industry-leading softswitches and feature
servers. Acting as a gateway, this device converts
IP signaling from the carrier into traditional
TDM voice services as well as PSTN fed
enterprises to IP .
Resilient Call Routing / Processing
Using an internal switchboard and dial plan,
the NetVanta Series dynamically routes three-
to 10-digit voice calls to the preferred service
provider based on the phone number dialed.
This least-cost routing functionality directs local
calls to one service provider and long distance
calls to another. Number substitution capability
is also available. Circuit consolidation offers
additional cost savings.
In addition, failover from unresponsive
servers is achieved with Primary/Secondary
SIP server configurations for each trunk. The
NetVanta 644 also offers SIP trunk failover
where calls routes from one trunk to another if
appropriate SIP responses are not received. In
the case of DNS failures, FQDN's allow resilient
trunk routing.
Smart Solutions for a
Connected World.
International
Functionality to eliminate inactive trunks
includes SIP keepalives as well as RFC4028 SIP
session timers.
Redundancy
The NetVanta 644 features redundant Ethernet
functionality, which provides Layer 1 failover
in the event one Ethernet link is lost, or a
cable fails. In addition, the Ethernet ports can
operate in a standalone interface mode which
can provide a solution for network failover with
least cost IP routing.
Voice Quality Monitoring
The ability to implement and manage voice QoS
is becoming a critical part of successful opera-
tions. QoS-enabled network devices can provide
better performance and higher service levels for
delay-sensitive VoIP or other mission-critical
applications, as well as accommodating the
lower priority traffic on the same infrastructure.
ADTRAN VQM builds on QoS to provide a
sophisticated level of network performance
visibility. ADTRAN VQM examines VoIP data
streams for each voice call, records the voice
quality information, and enables network
managers to identify problem areas in an easy-
to-use, graphical interface.
Management
The NetVanta 644 Series can be remotely
managed by either the ADTRAN n-Command
MSP or n-Command Enterprise Edition
management platforms. ADTRAN n-Command
platforms offer the ability to discover devices,
make mass configuration changes or firmware
upgrades, backup/restore configuration, and
generate inventory reports for asset manage-
ment. The ADTRAN n-Command MSP also
offers VoIP VQM and reporting, as well as an
industry leading, easy-to-use, Graphical User
Interface (GUI).
NetVanta 644 products are housed in
a rugged metal enclosure; available in wall-
mount, rackmount, and desktop mountings.
NetVanta 644 products are backed by free
firmware updates and ADTRAN's world-
class technical support.
