Configuring Cisco Multimode G.SHDSL

EFM/ATM in Cisco ISR G2

OL-24505-04

Last Updated: October 14, 2013

This document describes how to configure Cisco G.SHDSL Ethernet in the first mile (EFM) and

Asynchronous Transfer Mode (ATM). Cisco G.SHDSL EFM/ATM Enhanced high-speed WAN interface

card (EHWIC) connect Cisco Integrated Services Routers Generation 2 (ISR G2s) with central office

Digital Subscriber Line Access Multiplexers (DSLAMs) and provide up to four lines of G.SHDSL

(ITU-T 991.2) connectivity. The C888EA provides four pairs of multimode G.SHDSL connectivity.

There is one EHWIC model and one fixed platform model:

•EHWIC-4SHDSL-EA—A double-wide multimode EHWIC G.SHDSL, 4 pair, 802.3ah, EFM and

ATM mode interface card

•C888EA—A multimode G.SHDSL, 4 pair 802.3ah, EFM and ATM mode fixed platform

Prerequisites for Cisco G.SHDSL EFM/ATM EHWICs

•Ensure that you have the appropriate Cisco router to serve as the host router.

The following Cisco routers support Cisco G.SHDSL EFM/ATM EHWICs:

–

Cisco 1921 ISR

–

Cisco 1941 ISR

–

Cisco 2901 ISR

–

Cisco 2911 ISR

–

Cisco 2921 ISR

–

Cisco 2951 ISR

–

Cisco 3925 ISR

–

Cisco 3925-E ISR

–

Cisco 3945 ISR

–

Cisco 3945-E ISR

•Use the show version command to ensure that the router is running the correct IOS software. The

C888EA and EHWIC-4SHDSL-EA models require Cisco IOS Release Release: <optional, example:

Cisco IOS Release 15.1(1)T> or later.

Note When minimum release requirements are met, you can change images on the router without

affecting performance.

•Install the Cisco G.SHDSL EFM/ATM EHWIC on the router, using the directions provided in Cisco

Interface Cards Hardware Installation Guide and Cisco Network Modules and Interface Cards

Regulatory Compliance and Safety Information.

Information About Cisco G.SHDSL EFM/ATM

Cisco G.SHDSL EFM/ATM EHWICs support up to four pairs of digital subscriber lines (DSL). The

fixed platform model (C888EA) also supports up to four pairs. The DSL pairs are bundled in groups and

configured in the Cisco IOS command-line interface (CLI) by using the dsl-group command. Selecting

the mode is done by using the mode command.

See the “Command Reference” section on page 49 for more information about commands used with

Cisco G.SHDSL EFM/ATM.

Information About Cisco G.SHDSL EFM/ATM

Configuring Cisco Multimode G.SHDSL EFM/ATM in Cisco ISR G2

Cisco G.SHDSL EFM/ATM

The Cisco EHWIC-4SHDSL-EA provides up to four lines of connectivity through one RJ-45 connector

(see Figure 1), in EFM or ATM modes. The Cisco 888EA fixed platform (see Figure 2) supports up to

four lines of connectivity through one RJ-45 connector, in EFM or ATM modes.

Note The C888EA and the Cisco EHWIC-4SHDSL-EA support the Dying Gasp feature. The term dying gasp

refers to power status as defined in ITU-T standard G.991.2, section 7.1.2.5.3.
