Cisco Cisco IOS Software Release 12.4(6)T

HWIC-1ADSL and HWIC-ADSL-B/ST  support ADSL-over-POTS (ADSL, ADSL2, and 
ADSL2+), complying with Annex A of ITU G.992.1, G.992.3, and G.992.5.

HWIC-1ADSLI and HWIC-ADSLI-B/ST support ADSL-over-ISDN (ADSL, ADSL2, and 
ADSL2+), complying with Annex B of ITU G.992.1, G.992.3, and G.992.5. They also support and 
comply with ETSI 101-388 and the Deutsche Telekom U-R2 specification.

Supports reach-extended ADSL2, complying with Annex L of ITU G.992.3.

Complies with ANSI T1.413 issue 2.

Supports ATM AAL5 services and applications, ATM class of service (constant bit rate [CBR], 
variable bit rate-nonreal time [VBR-NRT], variable bit rate-real time [VBR-rt], and unspecified bit 
rate [UBR]) and up to 23 virtual circuits on an HWIC in Cisco routers.

Provides ATM traffic management and Quality of Service (QoS) features to enable service providers 
to manage their core ATM network infrastructures.

Supports Dying Gasp functionality.

Supported ISDN features on HWIC-ADSL-B/ST and HWIC-ADSLI-B/ST are as follows:

Provides an industry-standard, full duplex, 2B+D, S/T, data only hardware interface.

Operates independently of the ADSL interface on the HWIC.

This section describes the interface numbering scheme for Cisco integrated services routers If an 
interface card is installed in a Cisco 1800 series (modular), Cisco 2800 series, or Cisco 3800 series 
router, the interfaces must use a triple-number scheme to identify them. This triple-number assignment 
is different from the standard interface numbering scheme on other Cisco routers.

 shows the interface numbering for the onboard Fast Ethernet ports and the interface slots on 

Cisco 1800 series (modular), Cisco 2800 series, and Cisco 3800 series integrated services routers.
