Overview
The Cisco IAD2430 series IADs aggregate multiple channels of data and voice or fax user-side traffic
for transport over single or multiple WAN uplinks. Voice or fax traffic is transported by 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).
The Cisco IAD2430, Cisco IAD2431, and Cisco IAD2432 series routers consist of five models with a
common front panel (Figure 1). The Cisco IAD2435 series router consists of one model
(Cisco IAD2435-8FXS) with a different front panel (Figure 2). The Cisco IAD2430, Cisco IAD2431,
and Cisco IAD2432 series routers include a slot for the external flash memory card, as well as console,
auxiliary, and flash (CF) memory ports. The front panel, labeled “Cisco IAD2400 Series,” is identical
for all models. However, the back panels, labeled by specific model number, vary considerably,
depending on interfaces, ports, and options. Analog voice ports use an RJ-21 interface.

Chassis Grounding
Chassis Grounding
Chassis grounding is provided through the power cable, which uses a standard grounding plug. The
chassis is also equipped with two 4 x 0.7 screw terminals for chassis grounding. The accessory kit
contains a crimp-type ground lug that attaches to the two screw terminals. For more information, see the
“Installing the Ground Connection” section on page 3-14.
Memory
The Cisco IAD2430 series routers contain flash memory and main memory.
Onboard flash memory contains the Cisco IOS software image, boot flash contains the ROMMON boot
code, and counterfeit prevention contains the cookie configuration.
The default flash memory for the Cisco IAD2430 series IADs is 128 MB. Onboard CPU memory is
256 MB.
Port Numbering Conventions
Port numbering conventions for Cisco IAD2430, IAD2431, and IAD2432 series IADs are as follows:
•An external flash memory card is numbered CF 0.
•The 10/100BASE-T ports are numbered 10/100BASE-T 0/0 and 10/100BASE-T 0/1, from right to
left.
•The T1/E1 ports are numbered T1 1/0 or E1 1/0 and T1 1/1 or E1 1/1, from right to left.
•The slot for WICs and VICs is numbered slot 0. WIC and VIC interfaces are numbered by interface
with this slot number and an interface number, beginning with 0 and numbered from right to left.
•FXS voice port numbering begins at 2/0 and extends to 2/7, 2/15, or 2/23, depending on the number
of voice ports.

Specifications
Port numbering conventions for the Cisco IAD2435 series IAD are as follows:
•Fast Ethernet ports are numbered 0 and 1, from left to right.
•The controller T1/E1 port is numbered T1 0 or E1 0, from left to right.
•FXS voice port numbering begins at 0 and reaches a maximum of 7, depending on the number of
voice ports, from left to right.

et09186a008019aded.html
Software Elements
The operating system for the Cisco IAD2430 series IADs is the Cisco IOS software that resides in flash
memory.
Software Images
Images c2430-is-mz and c2430-ik9o3s-mz can be loaded on the following platforms which have T1E1
and VWIC ports:
•IAD2431-8FXS
•IAD2431-16FXS
•IAD2431-1T1E1
•IAD2432-24FXS
Images c2430-i6s-mz and c2430-i6k9o3s-mz should be loaded on the IAD2430-24FXS, which does not
have a VWIC slot.
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 serial port
•Remotely, with a connection through the serial port and a modem
•Through Telnet and TFTP

Interfaces and Service Capabilities
Configuration Methods
You can configure a Cisco IAD2430 series IAD automatically using the Simple Network-Enabled
Auto-Provision (SNAP) option, or you can configure theCisco IAD2430 series IAD manually using
several methods listed in “Manual Configuration” section on page 1-11.
Automated Configuration
If your Cisco IAD2430 series IAD was ordered with the 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 additional information about SNAP, see
the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122t/122t8/ftapiad8.htm
Note The SNAP option is not available on the Cisco IAD2435 IAD.
Manual Configuration
When you install a Cisco IAD2430 series IAD, see the “Power-On Procedure” section on page 4-1 for
the initial configuration. This configuration 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.
You can use any of several manual 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
Interfaces and Service Capabilities
Table 1-1 describes the various physical ports and the services that each port type supports, including
the following.
•Two administrative ports—One console and one auxiliary.
Note The Cisco IAD2435 IAD provides a connection to the terminal or PC for software
configuration or troubleshooting. The console port may be configured as a virtual auxiliary
port for dial backup and remote management.
•One or two 10/100BASE-T LAN ports.
•One or two Fast Ethernet ports.
