1 Introduction
This User's Manual describes how to configure and manage your AudioCodes product
(hereafter, referred to as
device ). This document is intended for the professional person
responsible for installing, configuring and managing the device.
1.1 Product Overview
The Mediant 500 Multi-Service Business Router (MSBR) is a networking device that
combines multiple service functions such as a Media Gateway, Session Border Controller
(SBC), Data Router and Firewall, LAN switch, WAN access, and an integrated general-
purpose server. The device offers enhanced dialing plans and voice routing capabilities
along with SIP-to-SIP mediation, allowing enterprises to implement SIP Trunking services
and IP-based Unified Communications, as well as flexible PSTN and legacy PBX
connectivity.
The device is designed as a secured Voice-over-IP (VoIP) and data platform. Enhanced
media gateway security features include, for example, SRTP for media, TLS for SIP
control, and IPSec for management. Data security functions include integrated Stateful
Firewall, IDS/IPS, SSL for remote user access, and site-to-site VPN. A fully featured
enterprise class SBC provides a secured voice network deployment based on a Back-to-
Back User Agent (B2BUA) implementation.
The device offers call "survivability" solutions using its Cloud Resilience Package
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 the following interfaces:

Multiple WAN:
•
Single Gigabit Ethernet copper (10/100/1000Base-T) unshielded twisted pair
(UTP) interface port
•
Dual-mode of 1.25 Gbps Optical Fiber Small Form-Factor Pluggable (SFP).
•
ADSL2+ / VDSL2
•
Symmetric High-Speed Digital Subscriber Line (SHDSL) - supports up to four
copper wire pairs according to G.991.2, acting as a remote-terminal CPE device.
Both ATM and EFM modes are supported. In the ATM mode, a variety of
protocols are supported, including PPPoE, PPPoA, and RFC 2684 in both
bridged (Ethernet-over-ATM) and routed (IP-over-ATM) variants. In the EFM
mode, the SHDSL port functions as a logical Ethernet device.
•
3G Cellular WAN access (primary or backup) using a USB modem

Four Gigabit Ethernet (10/100/1000Base-T) LAN ports

(Optional, customer-ordered) Wireless LAN 802.11n (Wi-Fi) access point at 2.4 and 5
GHz, integrated 2 Tx and 2 Rx, enabling data rates of up to 300 Mbps. Two Wi-Fi
antennas. The Wi-Fi interface also supports 802.11b/802.11g backward compatibility,
allowing interoperability of multiple devices with different types of Wi-Fi.

Two USB ports for an optional, 3G cellular WAN modem and/or USB storage services

Serial console port (RJ-45) for device management

PSTN telephony interfaces:
•
(Optional, customer-ordered) Single ISDN PRI (E1/T1) port
•
(Optional, customer-ordered) Two BRI ports, supporting up to four voice channels
as well as PSTN fallback
