AudioCodes M1KB-ESBC-25 Sessions

The Mediant 1000 Hybrid Media Gateway (AudioCodes M1KB-ESBC-25) is a modular, compact and cost-effective media gateway solution which has been designed to interface between TDM and IP networks in enterprises or small-scale carrier locations. The compact Mediant 1000 modular gateway is extremely scalable and supports multiples of 1, 2 or 4 E1/T1/J1 spans or 1 to 24 analog ports in various FXS/FXO configurations. The Mediant 1000 also supports mixed digital/analog configurations. This Mediant 1000 option offers the user 25 concurrent sessions. 

AudioCodes M1KB-ESBC-25 Sessions Overview 

The Mediant 1000B is based on VoIPerfect, AudioCodes' underlying, best-of-breed, media gateway core technology for all of its products. The Mediant 1000B provides superior voice-technology for connecting legacy telephone and PBX systems to IP networks, as well as seamless connection of the IP-PBX to the PSTN. In addition to operating as a pure media gateway, the Mediant 1000B can also host partner applications and serve as an IP-PBX platform via an OSN3 Module. The Mediant 1000B is fully interoperable with multiple vendor gateways, Softswitches, gatekeepers, proxy servers, IP phones, Session Border Controllers and firewalls.

The Mediant 1000B matches the density requirements for small locations while meeting enterprises' and service providers' demands for scalability. The compact Mediant 1000B Modular Gateway is extremely scalable and supports multiples of 1, 2, or 4 E1/T1/J1 spans, 4 to 20 BRI ports or 1 to 24 analog ports in various FXO/FXS configurations. The Mediant 1000B also supports mixed digital/analog with media processing capabilities such as conferencing, play/record configurations.

The Mediant 1000B can support a variety of telephony interfaces. The digital module can be configured as regular E1/T1/J1 interfaces, with up to 1 or 2 paired spans acting as life-line interfaces for switching to the PSTN in case of power failure or network problems. The analog module is available as regular FXS or FXO interfaces, where 1 FXS line can be used as a life-line interface for switching to the PSTN.

The Mediant 1000B extends the flexibility of the Media Gateway family with additional deployment options. The open platform on the Mediant 1000B offers partners the option to host their own applications (e.g., IP-PBX, call center, conferencing and messaging applications) using the OSN (Open Solution Network) Server platform, including a powerful processor and hard disks to provide a complete solution within the Mediant 1000B chassis along with rich SIP gateway features.
