Avaya G860 Media Gateway

Avaya G860 Media Gateway

The Avaya G860 media gateway is a DS3-capable, high channel density standards-compliant, VoIP media gateway system. It provides a robust, scalable, and modular solution designed for a large campus or call center with high availability and reliability. To support high availability, the Avaya G860 Media Gateway features automatic protection switching and full redundancy of all common equipment.

G860 is a high capacity, cost-effective IP telephony trunking system that supports up to four T3s (redundant 3+1 media gateway board configuration). The media gateway supports SIP for interoperability with a wide range of communications applications.

G860 features include:

●G860 support up to 5000 voice channels in Avaya Communication Manager Configuration

●Supports multiple DS3s

●Redundant power supply units, System controller, Ethernet switch

●Optional N+1 media gateway boards

●Scalable density options

●Open, scalable SIP-based architecture

Figure 57 and Figure 58 show the front and back views, respectively, of the G860 Media Gateway.
