The TMG7800 is a high performance, High Density SS7 Media and VoIP gateway. A new generation media and VoIP gateway with advanced features including "Any to Any Switching", SS7/C7 direct termination and a green footprint with less than 2240 watts fully loaded. Supports up to (1024) T1, D1 or J1 primary rate ISDN interfaces or (16) OC-3STM-1 or up to (48) DS-3s. Supports universal and wireless CODECs with T.38 FAX support.


Product Information

The Tmedia™ TMG7800 is a very highly scalable, carrier-grade media gateway system that meets the needs of service providers looking to harness the convergence between TDM and IP networks, consolidating multiple racks of devices for call control and media into a single system. The TMG7800 media gateway system provides capacity of up to 32,768 universal voice ports and the flexibility to switch between TDM and IP signaling services such as SS7, ISDN, SIGTRAN, SIP, and H.248, as well as popular media processing codecs across a mix of T1/E1/J1, DS-3 and STM-1 interfaces, all within the same system.

Leveraging redundant integrated media gateway controllers or in conjunction with one or more H.248-compliant softswitches, the TMG7800 delivers core network services such as media gateway, TDM switching, VOIP hairpinning, transcoding, advanced call routing and fax relay. With separate chipsets for
media processing and interactive voice response (IVR), and signaling performed in hardware, the TMG7800 media gateway provides full non-blocking capability of up to 32,768 channels per system.

The TMG7800 media gateway provides the ultimate in flexibility, easily scaling to full rack capacity of 1024 T1/E1/J1, 48 DS-3 or 16 STM-1 interfaces as service uptake increases, with the ability to mix and match different interface types. With an average 66% less power consumption than competing products of similar capacity, the TMG7800 media gateway supports the drive by service providers to reduce the environmental impact of their network footprint and increase their profitability and green credentials.
