Overview

AudioCodes' Mediant 1000B Gateway and E-SBC (hereafter referred to as device) is a
member of AudioCodes family of Enterprise Session Border Controllers (E-SBC), 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. Enhanced media gateway security
features include, for example, SRTP for media, TLS for SIP control, and IPSec for
management. 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 also offers call "survivability" solutions using its Stand Alone Survivability (SAS)
or 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 also provides an integrated Open Solution Network (OSN) Server module
(based on an Intel CPU). The OSN can host a variety of third-party applications such as IP-
PBX, Call Center, and Conferencing.
The device supports various telephony interfaces, available according to model (refer to
the Release Notes):

Up to 6 Foreign Exchange Station (FXS) modules, where each module provides 4
FXS port interfaces. This is used for connecting legacy telephones, fax machines, and
modems to the IP network. The FXS interfaces also support an analog Lifeline,
enabling an FXS port to connect directly to the PSTN upon power and/or network
failure.

Up to 6 Foreign Exchange Office (FXO) modules, where each module provides 4 FXO
port interfaces. This is used for connecting analog lines (PBX or PSTN) to the IP
network. When deployed with a combination of FXO and FXS interfaces, the device
can be used as a PBX for small office home office (SOHO) users, and businesses not
equipped with a PBX.

Up to 6E1/8T1 spans, available in 1, 2, or 4 spans per module, for connecting the
PSTN/PBX to the IP network. These modules can be configured with up to 1 or 2
paired spans for switching to the PSTN in case of power or network failure (PSTN
Fallback).

Up to 5 Basic Rate Interface (BRI) modules, where each module provides 4 BRI ports
(therefore, supporting up to 20 BRI digital ports). This is used for connecting BRI-
based PSTN or PBX lines to the IP network. The BRI module can be configured for
PSTN Fallback, switching to the PSTN in case of power failure or network problems.

Up to 4 MPM modules for media processing such as announcements and
conferencing.
