Gateways

A VoIP gateway is hardware equipment that converts Time Division Multiplexing (TDM)
telephony traffic from the Publicly Switched Telephone Network (PSTN) into digital IP packets
for transport over an IP network. A VoIP gateway can also convert digital IP packets into TDM
telephony traffic for transport across the PSTN. VoIP gateways have become a central, yet
complex, component in most state-of-the-art VoIP systems. Other functions of a VoIP gateway
include voice compression or decompression, control signaling, call routing, and packetization.
VoIP gateways come in many different configurations. Toshiba sells some third party gateways.

between TDM & IP networks in enterprises or
small-scale carrier locations. Incorporating
AudioCodes' innovative Voice over Packet technology, the Mediant 1000 enables rapid time-to-
market and reliable cost-effective deployment of next-generation networks.
The Mediant 1000 is based on VoIPerfect, AudioCodes' underlying, best-of-breed, media gateway
core technology for all of its products. The Mediant 1000 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. The Mediant 1000 is fully interoperable with multiple vendor gateways,
Softswitches, gatekeepers, proxy servers, IP phones, Session Border Controllers and firewalls.
The Mediant 1000 matches the density requirements for small locations while meeting enterprises'
and service providers'demands for scalability. The compact Mediant 1000 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 1000 also supports mixed digital/
analog with media processing capabilities such as conferencing, play/record configurations.
The Mediant 1000 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.
Interface Modules:
• Digital (E1/T1/J1) – connecting the PSTN or PBX to the IP-network
• Analog FXS – connecting analog phones to the IP-network
• Analog FXO – connecting analog trunks to a CO line
