NetVanta 6355
IP Business Gateway
The NetVanta
®
6355 IP Business Gateway is
a unique, all-in-one solution for Hosted VoIP
PBX services, Internet access, and business
connectivity.
This powerful platform combines
the voice functionality of ADTRAN’s industry-
leading Total Access
®
900e IP Business Gateway
and the widely deployed NetVanta Power over
Ethernet (PoE) Switch-Router into a compact
1U chassis. This all-in-one product includes a
robust SIP gateway, a full-featured IP router,
stateful inspection firewall, VPN, 24-port
powered (802.3af) Fast Ethernet switch
with Gigabit uplinks, and two expansion
slots for Network and Voice Interface Modules
(NIMs/VIMs).
Hardware and System Features
The modular NetVanta 6355 is powered by
the ADTRAN
®
Operating System (AOS) and
includes data networking features such as
standards-based routing protocols and Layer
3 Quality of Service (QoS). The integral switch
provides 24 powered (802.3af) 10/100 Ethernet
ports, with 802.1q VLANs, link aggregation,
and Gigabit uplinks for stacking. Voice support
includes built-in dual trunk (FXO) and station
(FXS) interfaces for analog connections and
E911 dialing. Network and voice expansion
options include analog four-port trunk (FXO),
analog four-port station (FXS), analog two-
trunk/two-station, PRI, ADSL, SHDSL, E1/FE1
and T1/FT1 modules provide support for up
to two network E1s and up to 10 analog
interfaces. Wallmount or rackmount
applications are supported.
SIP Gateway and Voice Functionality
The NetVanta 6355 includes a robust SIP
gateway, providing interoperability with
industry-leading softswitches, feature servers,
and media gateways. For customers imple-
menting a Hosted PBX service, the NetVanta
6355 supports IP phones, digital telephony
equipment and analog phones, fax machines,
or modems. In addition, the NetVanta 6355
works in conjunction with industry-leading
feature servers to support many popular
calling features including caller ID, call hold,
forward, transfer, and call waiting. A dual IP
and TDM backplane architecture supports
both IP and analog devices to smooth network
migration and eliminate common perfor-
mance problems associated with converting
TDM analog devices to IP. For example,
fax and modem devices connect directly

performance across the PSTN. Voice Activity
Detection (VAD) and silence suppression are
also supported.
Remote Survivability
The NetVanta 6355 includes a SIP Back-to-Back
User Agent (B2BUA) as a SIP-transparent proxy
to facilitate remote survivability in the event of
a service interruption on the WAN. If connec-
tion to the feature server is lost, calls may
continue between IP and analog phones to
an FXO POTS line to the PSTN.
Standard-based Routing Protocols
Complementing the versatile hardware, the
AOS allows for the support of standards-based
switching, VLAN tagging, static and default
routes, demand routing, Network Address
Translation (NAT), and DHCP client/server/
relay. This enables fast, accurate network
convergence using routing protocols such
as BGP, OSPF, and RIP. In addition, the
NetVanta 6355 terminates Frame Relay,
Multilink Frame Relay, PPP, Multilink PPP,
and HDLC WAN protocols.
Quality of Service (QoS)
QoS is also supported for delay-sensitive
traffic. To prioritize mission-critical traffic and
control network congestion, the NetVanta 6355
uses Low Latency Queuing, Weighted Fair
Queuing (WFQ), Class-based WFQ, DiffServ
marking, and Frame Relay Fragmentation.
Security
The NetVanta 6355 provides a powerful, high
performance, stateful inspection firewall that
can identify and protect against common
Denial of Service (DoS) attacks.
Administration
The NetVanta 6355 offers a standard Command
Line Interface (CLI) that mimics the widely
adopted, industry de facto standard, virtually
eliminating training costs associated with
relearning a new operating system. The CLI
also allows for configuration scripts to be used,
saved, and downloaded as a quick and easy
recovery mechanism. In addition, an intui-
tive Web-based Graphic User Interface (GUI)
provides step-by-step configuration wizards,
management capability, and the ability to
upload firmware updates. The ability to
discover devices, make mass configuration
changes or firmware upgrades, backup and
restore device configurations, push mass
configuration changes, upgrade firmware to
groups of devices, and generate inventory
reports for asset management is available
using ADTRAN’s n-Command
