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 iwth 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 to the
NetVanta 1355 and achieve full-rate perfor- mance 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 traffc. To prioritize mission-critical traffc 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 frewall 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 confguration 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 confgu- ration wizards, management capability, and the ability to upload frmware updates. The ability to discover devices, make mass confgu- ration changes or frmware upgrades, backup and restore device confgurations, push mass confguration changes, upgrade frmware to groups of devices, and generate inventory reports for asset management is available using ADTRAN’s n-Command tool.
