Carrier Access Adit 3402 Series
High-Bandwidth Multi-Service Router


Routing, Inspection, and Protection at Wire-Speeds through Scalable T1 or Ethernet Interfaces

Aditฎ 3402 High-Bandwidth Multi-Service Routers are a new breed of access routers that delivers converged
voice and secure IP access to the enterprise at a disruptive price and unmatched performance. The Adit 3402
delivers speed, security, and scalability for secure Internet access, web hosting, private IP services, LAN-to-
LAN connectivity, storage, and telephony applications—all in a single platform. The Adit 3000 series integrates
and consolidates the features of a high-performance router, stateful firewall, T1 CSU/DSU, and integrated
access device into a single element at an unmatched price/performance ratio without sacrificing speed or
security. Its scalability on WAN and LAN interfaces make it an ideal device for Small- to Medium-sized
Business (SMB) locations with expanding throughput needs. A comprehensive feature set, including integrated
security, allows a single device to protect corporate network assets. The latest IP network processor technology
enables a rich and easily expandable feature set that supports high-performance real-world applications for
enterprises and service providers alike. One Adit 3402 will grow with a business’ needs through three different
performance classes of traditional routers to 100 Kpps, even at small packet sizes with firewall and packet
inspection features activated.

Carrier-Class Services
Designed to deliver carrier-class features and unparalleled performance at the enterprise, the Adit 3402 scales
beyond the typical one T1 WAN port to a maximum of four ports without adding hardware. T1 ports can be
bonded together to form a single logical circuit with an aggregate bandwidth of up to 6 Mbps. Optionally, the
second Ethernet port can be utilized for metro Ethernet WAN service with bandwidth scaling to 100 Mbps
delivering wire-speed routing performance. The Adit 3402 scalability does not increase the complexity of the
system. All T1 and 10/100Base-T interfaces are included in the rugged package. Additional interfaces and
enhanced features are activated through software keys, eliminating difficult hardware and software upgrades.
The interfaces are not fixed function, so the second Ethernet port can serve not only as a WAN port, but also
as a second LAN segment utilized for Voice over IP (VoIP) segment or as a Demilitarized Zone (DMZ). Best of
all, no site visits are required to increase performance or manage the system, reducing cost, personnel, and
support to maintain the network.

IP Security Without Sacrificing Performance
Integrated stateful firewall keeps the network and LAN segments secure from intrusions and attacks while
allowing authorized access to network resources. Included in the base router package are Network Address
Translation/Network Address Port Translation (NAT/NAPT), stateful packet inspection, flow classification,
Application Layer Gateway (ALG), and Intrusion Detection System (IDS). Rules are combined with Access
Control Lists (ACL) to protect traffic flowing in and out of the network. Future software releases will expand
these capabilities as new applications layer gateways are created and attacks are discovered. The Adit 3402
maintains wire-speed throughput with low latency even with small packets while stateful packet inspection and
dynamic flow classification features are enabled.

Designed for IP Network Management
The Adit 3402 router’s management capability enhances its carrier-grade performance. Whether managed
locally through the serial craft port or remotely via telnet, standardized interfaces make configuration and maintenance
easy. Network management systems can remotely provision and alarm monitor the Adit 3402 via
SNMP or technicians can manager and monitor through a standard Command Line Interface (CLI). The router
can be automatically configured and upgraded remotely via TFTP.
The Adit 3402 leverages Carrier Access’ experience in delivering and supporting over three million carrier-grade
business access lines, Internet connections, and VoIP connections as well as its carrier-class interoperability
alliances. The router comes with our standard five-year warranty on hardware and comprehensive maintenance
packages. Adit 3402 expands the range of service applications and revenue opportunities with the quality and
support that have made Carrier Access the standard for enterprises and major service providers.
