System Overview
AudioCodes' Mediant 4000 E-SBC is a member of AudioCodes family of Enterprise Session Border Controllers,
enabling voice-over-IP (VoIP) connectivity and security between the Enterprise and Internet Telephony
Service Provider (ITSP) networks. The Mediant 4000 E-SBC is a fully featured enterprise-class SBC, providing
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 IP PBX to any service provider; and service assurance for
service quality and manageability.
The Mediant 4000 E-SBC also provides a call "survivability" feature with Local Mode survivability, maintaining
service continuity to Enterprises served by centralized SIP-based IP Centrex servers, or branch offices of
distributed enterprises. Local Mode enables internal office communication between SIP clients in the case of
disconnection from the centralized IP Centrex server or IP PBX.
The Mediant 4000 E-SBC offers the following redundancy features:
•
1+1 High Availability, deploying two Mediant 4000 E-SBC devices where both are connected to the same
broadcast domain/s.
•
1+1 LAN interface redundancy through its eight 10/100/1000Base-T Ethernet ports. These ports are
grouped in pairs, where one port is active and the other standby.
•
1+1 Power load-sharing and redundancy through its two Power Supply modules.

Assigning an IP Address to the Mediant 4000 E-SBC
The Mediant 4000 E-SBC includes an embedded Web server (Web interface), providing a user-friendly
graphical user interface (GUI) for Web-based configuration. The default management and voice IP network
address is used to initially access this Web interface and can be changed if necessary to suit the network
addressing scheme in which the Mediant 4000 E-SBC is deployed. In addition, the eight LAN ports on the
E-SBC module operate in pairs (groups) for providing 1+1 LAN redundancy, where one serves as the active
port while the other as standby. Each LAN port pair can be connected to a different LAN subnet, enabling
the Mediant 4000 E-SBC to bridge the VoIP traffic between subnets. The procedure below describes how to
change this default management IP address to suit your network addressing scheme.
To assign an IP address to the Mediant 4000 E-SBC:
1.
Connect one of the LAN ports on the E-SBC module directly to the network interface on your
computer, using a straight-through Ethernet cable.

2.
Change the IP address and subnet mask of your computer to correspond with the default IP
address and subnet mask of the Mediant 4000 E-SBC (192.168.0.2 with subnet mask
255.255.255.0).
3.
On your computer, open a standard Web browser, and then in the URL address field, enter the
Mediant 4000 E-SBC default IP address 192.168.0.2; the Web Login screen appears,
prompting you to log in with your login credentials:
4.
Log in with the default, case-sensitive user name ("Admin") and password ("Admin"), and then
click Login; the Web interface appears, displaying the Home page.
5.
Open the Physical Ports Settings page (Configuration tab > VoIP menu > Network > Physical
Ports Table):
6.
Modify the required physical ports settings, by selecting the 'Index' button corresponding to the
port and then clicking Edit. You can configure the port Native VLAN ID and duplex mode, as well
as provide a brief description of the port. The displayed string value in the 'Port' column
represents the corresponding physical port on the E-SBC module, as displayed below:
