Carrier Access Enables VoIP Today
with SIP to PRI Trunk Gateway and Router

Carrier Access' Business Access technologies address the need to deliver converged voice, data and video services over circuit- and packet-based networks as well as ease the migration to IP. The Adit^® Platform is designed to lower the cost and complexity of delivering these services while leveraging existing network infrastructures.  Our Adit products support both voice and data services to ease the migration from circuit- to packet-based infrastructures. Internet Protocol (IP) provides the foundation for this convergence due to its efficiency, flexibility, scalability and cost-effectiveness. Security is also a vital capability to keep traffic flowing smoothly while protecting against intrusions and attacks.

The Adit 3000 series enables profitable, "best of class" deployment solutions for hosted voice-over-IP services. Traditional hosted VoIP service delivery solutions are multi-platform, have limited remote management capabilities, and do not scale well to provide DEMARC or desktop services. These limitations inhibit the flexibility of service options and operational efficiencies of service deployment.

The Adit 3104 SIP Business Gateway addresses these issues head-on with a platform that offers routing with Quality of Service (QoS), an integrated stateful firewall, scalable voice gateway capabilities, and simplified remote management designed for service provider deployment models. In just one platform, the Adit 3104 offers speed, security, and voice for: Secure Internet and IP access with fast processing stateful firewall LAN-to-LAN connectivity over private and public networks.

The new Adit 3500 SIP to PRI Trunk Gateway (see details below) replaces multiple devices and network elements at the customer premises that typically provide routing, security, and trunk gateway functions - offering a powerful combination of speed, security, data and voice.

Adit 3500 SIP to PRI Trunk Gateway and Router - Release 1.0  

Key Benefits :

• Comprehensive routing, firewall, VoIP gateway, and integrated Multi-T1 in a single platform
• WAN-Wide Area Network options include 2xT1 and Ethernet
• Full 24-channel voice channel capacity for all configurations and support for voice compression
• 4 FXS option for analog modems and faxes

Integrated PRI Trunk Gateway and Wire-speed Router

The Adit^® 3000 series of IP Business Gateways are a new breed of access platforms designed to deliver carrier-hosted voice and data services at a disruptive price with unmatched performance.  

The Adit 3500 integrates the features of a SIP (Session Initiation Protocol) to ISDN-Integrated Services Digital Network PRI (Primary Rate Interface) trunk gateway, high-performance router, and stateful firewall with flexible WAN options. The 3500 replaces multiple devices and network elements at the customer premises that typically provide routing, security, and trunk gateway functions - offering a powerful combination of speed, security, data and voice. Additionally, a 4 FXS (Foreign eXchange Station) option provides connectivity for analog fax, modems and telephones. The 3500 platform offers scalability and high-performance for Internet and IP access, LAN-to-LAN connectivity over private and public networks, and Voice over Internet Protocol (VoIP) PBX trunk service applications.

Converged IP Services without Sacrificing Performance

The Adit 3500 provides wire-speed 2xT1 throughput with low delay for all packet sizes. The Adit 3500's VoIP-aware routing engine is based on the latest advanced network processing technology and enables converged IP applications without the typical degradation in performance seen in other legacy solutions on the market. Full voice channel capacity is supported for all product configurations while supporting more than 50 voice lines using G.729 (low bandwidth 8 KBPS) compression and G.711.

By integrating routing and security features into a single network processor, the Adit 3500 cost-effectively supports Network Address (Private) Translation (NAT/NAPT), stateful packet inspection, flow classification, Application Layer Gateway (ALG) and intrusion detection. In addition, Access Control Lists (ACL) protect traffic flow in and out of the network. Integrated firewall secures the network and LAN segments from intrusions and attacks while allowing authorized access to network resources.  

Carrier-Grade VoIP Service Delivery

The Adit 3500 is a carrier-class solution that enables the key calling features used by today's business services. With a routing engine as its base, the Adit 3500 provides a scalable, integrated SIP to PRI trunk gateway that can terminate PBX traffic, and route both voice and data across public and private networks. The routing engine supports small packet size characteristics of full-capacity voice and data plus the Quality of Service (QoS) necessary to deliver carrier-grade voice.  

Dial Plan Features

The Adit 3500 PRI Trunk Gateway provides digit manipulation capabilities in order to address a range of small and medium business and enterprise applications. Digit stripping, prefix and postfix capabilities are supported along with multiple digit collection modes. PRI messaging supports industry leading Class 5 switches.  

Simplified Remote Provisioning, Configuration and Management

The Adit 3500's scalability does not increase its complexity. Remote provisioning is simplified through an easy-to-use web interface. Remote alarms from the Adit 3500 are reported via SNMP (Simple Network Management Protocol), Syslog, e-mail alerts, or through a web interface. The platform can also be remotely configured and upgraded.
