elements
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.
Mediant 3000 in Service Provider Networks
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 ts the
needs of wireline, cable, cellular and mixed service providers.
Mediant 3000 in Large Enterprises
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.
