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 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.

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.
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.
Specifications
For the Cisco IAD2430 series hardware and electrical speicfications, see the Cisco IAD2430 series data sheets at the following URL:
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
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.
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.
•The Cisco IAD2431 and Cisco IAD2432 IADs for a T1/E1 WAN interface are equipped with one or two T1/E1 WAN ports.
•Cisco IAD2430 series IADs for an analog voice user interface are equipped with an RJ-21 port for connection to a distribution panel.
•Cisco IAD2432 IADs for adigital voice user interface are equipped with a T1/E1 port for connection to a PBX.
All Cisco IAD2430 series IADs are customer premises equipment (CPE) only.
