All-in-One Network Access: Modular WAN Interface, Firewall, Ethernet Switch, IP Router, and Optional VPN

The NetVanta® 1000 Series from ADTRAN® is a standards-based, non-blocking Layer 2 switching solution available at a cost up to 50 percent less than competing switches. These devices are suitable for converged LAN/WAN access, interconnecting LAN devices, or for network segmentation. This series includes the NetVanta 1224R, 1224STR, and 1224STR DC, unique, all-in-one access platforms that combine a 24-port Ethernet switch, an IP access router, a modular WAN interface with built-in DSU/CSU, a stateful inspection firewall, and the option for Virtual Private Networking (VPN), all in a single 1U chassis. The 1224STR and STR DC provide 24-port Ethernet and Fast Ethernet switching and a 1000Base-T/SFP Gigabit port for uplink or stacking capability. The 1224STR DC is ideal for carrier networks requiring +24/-48VDC power.

Modular HardwareM

A single WAN access slot in the back of the NetVanta chassis supports a variety of Network Interface Modules (NIMs) including ADSL, 56/64k, T1/FT1, T1/FT1 with DSX-1, E1/FE1, E1/FE1 with G.703, Dual T1, or a serial interface. The optional Analog or ISDN BRI Dial Backup Modules (DIMs) support a solid business continuity plan by dialing around a failed circuit to any PPP-compliant device. The ADSL NIM may also be used for broadband backup, allowing for larger bandwidth applications and faster data rates.

Standard-based Protocols

Based on the ADTRAN Operating System (AOS), these devices offer support for 802.1Q Virtual LANs (VLANs), Port-based switching features include Broadcast Storm Control, 802.1D and 802.1w Spanning/Rapid Spanning Tree, Link Aggregation, Port Mirroring, and GVRP. Link Layer Discovery Protocol (LLDP) auto-discovers neighboring Ethernet devices, simplifying integration into multi-vendor environments. In addition the integral IP router provides costeffective Internet access, corporate Frame Relay or point-to-point connectivity using standard routing protocols such as BGP, OSPF and RIP.


Rest assured, with the NetVanta 1224R and STR your network is protected. Each platform comes standard with a stateful inspection firewall to stop intruders and common Denial of Service (DoS) attacks. These products also offer a variety of data security features including MAC-based port security, multilevel user passwords, Secure Shell (SSH) and Secure Socket Layer (SSL) for encrypted user login, and Access Authentication and Authorization (AAA) for authentication with a RADIUS or RSA SecurID server. For added security, these platforms offer a VPN upgrade supporting up to 500 IPSec tunnels using DES, 3DES or AES encryption.

Quality of Service (QoS)

These switch-routers support QoS to prioritize mission critical traffic and control network congestion at various layers of the OSI model. Ont the LAN, the NetVanta 1000 Series offers 802.1p and DiffServ Class of Service (CoS). To assign priority to traffic, Weighted Round Robin and Strict Priority Queuing is used with four egress queues per port. For the WAN, DiffServ marking, Low Latency Queuing, and Weighted Fair Queuing provide priority for IP packets routed over the WAN. Together these features offer a powerful end-to-end QoS story.

VoIP Ready

In combination with the QoS features, a specialized SIP Application Layer Gateway (ALG) allows SIP traffic to traverse NAT-enabled firewalls. For an enterprise network, this interoperability allows IP PBXs, phones, and other SIP-based devices to set up, tear down, and pass voice and call control messages seamlessly through the integral NAT-enabled firewall.


The AOS offers both a Command Line Interface (CLI) that mimics the widely deployed, industry de facto standard and an intuitive web-based GUI with step-by-step configuration wizards. Together these interfaces allow you to administer and control your network in the best method that meets your needs. For a centralized enterprise-wide management scheme, ADTRAN offers n-Command™, an intuitive, scalable software suite for managing firmware revisions, push firmware upgrades and configuration changes, backup and restore configurations, and manage security policies and Access Control Lists (ACLs).
