User's Manual 1. Overview
1 Overview
The Mediant 500 Enterprise Session Border Controller (E-SBC), hereafter referred to as
the device , is a member of AudioCodes family of E-SBCs, enabling connectivity and
security between small medium businesses (SMB) and service providers' VoIP networks.
The device provides SBC functionality as well as voice-over-IP (VoIP) media gateway
functionality. The device offers enhanced dialing plans and voice routing capabilities along
with SIP-to-SIP mediation, allowing enterprises to implement SIP Trunking services (IP-to-
IP call routing) and IP-based Unified Communications, as well as flexible PSTN and legacy
PBX connectivity.
The device is designed as a secured VoIP platform. A fully featured enterprise-class SBC
provides a secured voice network deployment based on a Back-to-Back User Agent
(B2BUA) implementation. The SBC functionality provides perimeter defense for protecting
the enterprise from malicious VoIP attacks; mediation for allowing the connection of any
PBX and/or IP PBX to any service provider; and service assurance for service quality and
manageability.
The device offers call "survivability" solutions using its Stand Alone Survivability (SAS) or
Cloud Resilience Package (CRP) applications, ensuring service continuity to enterprises
served by a centralized SIP-based IP-Centrex server or branch offices of distributed
enterprises. Call survivability enables internal office communication between SIP clients in
the case of disconnection from the centralized SIP IP-Centrex server or IP-PBX.
The device supports 1+1 High Availability when deployed with two devices, each
connected to a different network (in the same subnet). In case of a network failure in one
network, a switch over of traffic to the standby device occurs.
The device supports the following interfaces:

Four Gigabit Ethernet (10/100/1000Base-T) LAN ports

Single E1/T1 port interface over a copper wire pair, supporting Transparent, CAS and
ISDN protocols. The device supports various ISDN PRI protocols such as EuroISDN,
North American NI-2, Lucent™ 4/5ESS, Nortel™ DMS-100 and others. It also
supports different variants of CAS protocols for E1 and T1 spans, including MFC R2,
E&M immediate start, E&M delay dial / start, loop start and ground start

Two USB ports for optional, USB storage services

Serial console port (RJ-45) for device management
The device supports local and remote management through various management
platforms such as an HTTP/S-based Web server, a command-line interface (CLI), SNMP,
and serial (RS-232).
