The Mediant 3000 is a feature-rich, highly available VoIP gateway supporting low to medium channel densities. The Mediant 3000 compact footprint (2U) meets both the needs of service providers with geographically dispersed networks, as well as those of large enterprises, where reliable and dense VoIP gateways are necessary for business-critical communications.

Service Providers are currently migrating from centralized legacy TDM networks to decentralized IP networks. The Mediant 3000 is aligned with these developments, offering exceptional channel scalability of up to 2016 DSOs in a compact 19”-2U chassis, allowing it to be placed in small POPs, close to local telephone networks. Additionally, the Mediant 3000 delivers the same carrier-grade availability that service providers are accustomed to on their legacy equipment. A wide range of trunking and access protocols to suit any application are provided, such as PRI, V5.2 and CAS access protocols and SS7/M2UA/M3UA trunking protocols. The Mediant 3000 fits the needs of wireline, cable, cellular and mixed service providers.

The migration to VoIP in the enterprise is driven by cost considerations and the need for a richer, integrated telephony service. This transition leads to heterogeneous enterprise telephony networks that deploy multiple PBXs from various vendors, some of which are legacy and some of which are IP-based. An enterprise might choose to connect to a PSTN Service Provider or to an Internet Telephony Service Provider (ITSP) or both. The Mediant 3000 has comprehensive PSTN access capabilities as well as SIP to SIP interworking features that enable the interconnection between all these elements. Large enterprises typically deploy business critical contact centers where the high availability of the Mediant 3000 is a key factor. In addition to E1/T1 interfaces, the Mediant 3000 supports high-density PSTN interfaces, such as T3, STM-1 and OC3 to provide the enterprise with lower PSTN lease costs. The proven interoperability of the Mediant 3000 with different PBXs and PSTN switches facilitates smooth deployment.
