The NetVanta
®
1355 Multiservice Access
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 Multiservice
Access Device 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 1355 is powered by
the ADTRAN
®
Operating System (AOS) and
includes data networking features such as
multiple 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 FXO and FXS interfaces
for analog connections and E911 dialing.
Network and voice expansion options include
analog four-port trunk, analog four-port station,
analog two-trunk/two-station, PRI, and T1/
FT1 modules provide support for up to three
network T1s and up to 10 FXS/FXO interfaces.
Wall or rack mount applications are supported.
SIP Gateway and Voice Functionality
The NetVanta 1355 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
1355 supports IP phones, digital telephony
equipment and analog phones, fax machines,
or modems. In addition, the NetVanta 1355
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 performance problems
associated with converting TDM analog devices
to IP. For example, fax and modem devices
connect directly to the NetVanta 1355 and
achieve full-rate performance across the PSTN.
Remote Survivability
The NetVanta 1355 includes a SIP Back-to-Back
User Agent (B2BUA) to facilitate remote surviv-
ability in the event of a service interruption on
the WAN. If connection to the feature server is
lost, calls may continue between IP and analog
phones to an FXO POTS line to the PSTN.
Voice Activity Detection (VAD) and silence are
supported.
Standard-based Routing Protocols
Complementing the versatile hardware, the
ADTRAN Operating System (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 1355 termi-
nates 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 1355 uses
Low Latency Queuing, Weighted Fair Queuing
(WFQ), Class-based WFQ, DiffServ marking,
and Frame Relay Fragmentation.
Security
The NetVanta 1355 provides a powerful, high
performance, stateful inspection firewall that
can identify and protect against common
Denial of Service (DoS) attacks.
Administration
The NetVanta 1355 offers a standard Command
Line Interface (CLI) that mimics the widely
adopted, industry
de facto
standard, virtu-
ally 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 intuitive
Web-based GUI provides step-by-step configu-
ration wizards, management capability, and
the ability to upload firmware updates. The
ability to discover devices, make mass configu-
ration 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
®
tool.
