• SNMP The Cisco IOS software assigns an IP address to the AIC for use by the serial data channel. To route traffic, the serial data channel uses IP over synchronous High-Level Data Link Control (HDLC). All IP packets coming to the Cisco router with a destination IP address that matches the AIC’s IP address are forwarded to the serial data channel using IP over HDLC.
Configuring the AIC Cisco IOS commands are used for configuring the AIC IP address and the IP routing to the AIC NM. After the IP address and the IP routing are set, alarm configurations can then be set up with either TL1 or the AIC command-line interface.

G.SHDSL is supported on the G.SHDSL WAN interface card, a 1-port WAN interface card (WIC) for Cisco 2600 series and Cisco 3600 series routers. The G.SHDSL WIC is compatible with the Cisco 6015, Cisco 6130, Cisco 6160, and Cisco 6260 Digital Subscriber Line Access Multiplexers (DSLAMs). The DSLAM must be equipped with G.SHDSL line cards that are compatible with the DSL service to be configured.

This appendix describes the ROM monitor (also called the bootstrap program), which is the firmware that runs when you power on or restart the Cisco 2600 series, Cisco 3600 series, and Cisco 3700 series router. During normal operation, the ROM monitor helps to initialize the processor hardware and boot the operating system software.
Entering the ROM Monitor Mode From the Cisco IOS software, you can configure the router to automatically enter the ROM monitor mode the next time the router boots by setting virtual configuration register bits 3, 2, 1, and 0 to zero.
The Cisco 2600 series router does not have a dedicated boothelper image ([rx]boot) as used by some other Cisco routers. With the Cisco 2600 series router, the first image in flash memory is invoked as the default boothelper image anytime the ROM monitor does not recognize the device ID in the boot command.
