G250 Media Gateway

This branch-office gateway allows businesses to economically extend headquarters communications applications to small branch offices with two to fourteen extensions. It combines an IP telephony gateway, an advanced IP WAN router, a VPN gateway and a high-performance LAN switch in a compact (2U) rack-mount unit. With an advanced TDM/IP architecture, the G250 provides seamless connectivity and communications among analog, digital, H.323, and SIP-based IP telephony devices and applications

G350 Media Gateway

The G350 packs an IP telephony gateway, an advanced IP WAN router, a VPN gateway and a high-performance LAN switch into a compact (3U) modular chassis. Designed to be a complete voice/data networking solution, it is ideally suited for enterprises with distributed branch office locations of between eight and 72 extensions. An advanced TDM/IP architecture provides seamless connectivity and communications among analog, digital, H.323, and SIP-based telephony devices and applications.

G430 Media Gateway

The Avaya G430 Media Gateway provides a cost effective , scalable, and secure platform for delivery of Avaya Aura Communication Manager-based IP telephony applications. It is targeted for small to mid sized branch offices or medium sized standalone businesses. Like other Avaya GX50 series Media Gateways, it can be configured to extend Communication Manager features and applications to branch offices at the edge of the enterprise network.

G450 Media Gateway G450

Developed for mid- to large branch offices and medium sized standalone businesses, this gateway can be configured with an S8300 Server blade or S8500 Server to serve standalone or small campus environments. It consists of a 3U high rack-mountable chassis with a field-removable Supervisor Main Board Module, Power Supplies, Fan Tray, DSP resources and memory, along with eight Media Module slots to support T1/E1, ISDN-BRI, WAN interfaces, digital or analog telephones, and analog trunks.

G650 Media Gateway

Designed as the complementary gateway for S8500/S8700/10/20-based media servers, the G650 offers the features, scalability, and system uptime that enterprises require for mission-critical telephony. Its 8U high, fourteen-slot rack-mountable chassis can accommodate a range of analog, digital, ISDN, and IP (over the LAN) phone station configurations, with voice transport options over IP, analog, TDM, or ATM. Available dual redundant, load-sharing power supplies provide enhanced reliability.

G860 Media Gateway

Optimized for campuses and large contact centers, the G860 is a high-density trunking gateway that supports up to twelve DS3 interfaces in a single 5U chassis. It provides a money-saving solution for organizations that need to consolidate multiple DS1 interfaces, helping to reduce hardware costs, power bills and carrier charges. The GS860 uses SIP-based call control, and offers carrier-grade, NEBS III-compliant reliability, with redundant system elements and hot-swappable modules.

IG550 Integrated Gateway

Designed for branches of up to 100 users, the IG550 consists of Avaya telephony software and hardware, embedded in Jupiter Networks' J-Series branch-office routers�providing a one-box telephony gateway, routing and security solution. It delivers reliable converged networking in an easily managed package. As a consolidated solution, it helps reduce hardware, deployment and management costs, resulting in a competitive total cost of ownership.

S8300 Server

The S8300 Server with a G700, G450,G350 or G250 Media Gateway provides a flexible solution for growing companies to streamline voice and data operations over one networked infrastructure. It can be a standalone solution for a small business or a remote edge device for a larger enterprise network with 8 to 450 stations.

S8400 Server

The S8400 Server is a Linux-based server that provides Communication Manager processing functionality in stand alone, single port network, and telephony systems requiring up to 900 stations. The S8400 Media Server provides midsize enterprises with a cost-effective solution to support up to five media gateways and multiple locations. It also supports software for voice messaging, fax messaging, auto attendant and other applications

S8500 Server

Designed to support distributed IP for mid-sized and large businesses, this server offers powerful reliability features: It can be configured as a Local Survivable Processor (LSP), allowing it to act as a higher capacity LSP for larger remote sites of a distributed enterprise. It provides enterprise survivability, similar to ESS, allowing it to serve as a "regional" survivable server for multiple H.248 gateways. It Includes a RAM Disk, so it can operate even in the event of a disk failure. The S8510 Server running Communication Manager allows for a distributed enterprise over an IP infrastructure, ideal for the midsize or large business (up to 3,200 ports).

S8700 Server

The S8700 Server line offers three different models, all of which offer duplicated processors for greater reliability. The processors can be separated up to ten kilometers (6.3 miles) to help ensure business continuity. The S8710 Media Server is based around an Intel processor, while the S8720 Server and the S8730 Server use the AMD Opteron and AMD Opteron Quad Core processors, respectively.

S8800 Server

The S8800 series common server is a processing platform that is ready to support Avaya Aura communications solutions for midsized and large enterprises, today and in the future. The Avaya S8800 Server leverages Intel's latest Xeon E5500 series (Nehalem) processor technology, and is available in both 1U and 2U form factors. Most Avaya applications will use the S8800 1U server chassis; some applications that require a large number of hard disk drives and/or plug-in cards will use the 2U version of Avaya S8800 Server.
