Overview
The Cisco IAD2430 series integrated access devices (IADs) aggregate multiple channels of data and
voice or fax user-side traffic for transport over single or multiple wide-area network (WAN) uplinks.
Voice or fax traffic is transported by Voice over Internet Protocol (VoIP) or by Voice over Asynchronous
Transfer Mode (VoATM). All platforms support Media Gateway Control Protocol (MGCP), the signaling
protocol H.323, and Session Initiation Protocol (SIP).
Cisco IAD2430 series IADs support the following interfaces:
•
•
•
•
•
10/100BASE-T LAN connection
T1/E1 port connections
RJ-21 analog voice interface
WIC/VIC options
External/Internal compact flash
Cisco IAD2430 series IADs can be housed in a rack, mounted on a wall, or set on a benchtop surface.
Warning
This unit is intended for installation in restricted access areas. A restricted access area can be
accessed only through the use of a special tool, lock and key, or other means by security. Statement

Software Elements
Software Elements
The operating system for Cisco IAD2430 series IADs is the Cisco IOS software that resides in flash
memory.
Configuration Connections
You can use an ASCII terminal or a PC to configure a Cisco IAD2430 series IAD. The configuration can
be performed in several ways:
•
•
•
Locally, with a direct connection through the console port
Remotely, with a connection through the auxiliary port and a modem
Through Telnet and TFTP
Configuration Methods
Automated Configuration
If your Cisco IAD2430 series IAD was ordered with the Simple Network-Enabled Auto-Provision
(SNAP) option, no on-site configuration is required. When the Cisco IAD is powered on and connected
to the WAN, the SNAP application downloads the applicable configuration files automatically. For
Cisco 2420 Series IAD feature module at the following URL:
Manual Configuration
When a Cisco IAD2430 series IAD is first installed, use the procedure in
Chapter 4, “Powering On Cisco IAD2430 Series IADs,” for the initial configuration. This sets the basic
communication parameters. After the Cisco IAD is operating and able to communicate, use the
procedures in the Cisco IAD2430 Series Software Configuration Guide to configure the specific services
and functions, or to make changes to the existing configuration.
There are multiple methods for configuring a Cisco IAD2430 series IAD:
•
•
•
•
•
System configuration dialog
Configuration mode—Cisco IOS software command-line interface (CLI)
Setup command facility—Remote configuration through a LAN or WAN
SNMP-based application—CiscoView or HP OpenView
HTTP-based configuration server—Provides access to the CLI from a web browser
