ADSL HWICs
The ADSL high speed WAN interface cards (HWICs) feature for Cisco modular integrated services routers provide high-speed ADSL digital data transfer between a single customer premises equipment (CPE) subscriber and a central office (CO). ADSL HWICs are available in the following variations:
•
ADSL over POTS (ADSLoPOTS) HWICs
–HWIC-1ADSL, a 1-port ADSLoPOTS card
–HWIC-ADSL-B/ST, a 2-port card with a port for ADSLoPOTS and a data-only port for an ISDN BRI S/T connection
•ADSL over ISDN (ADSLoISDN) HWICs
–HWIC-1ADSLI, a 1-port ADSLoISDN card
–HWIC-ADSLI-B/ST, a 2-port card with a port for ADSLoISDN and a data-only port for an ISDN BRI S/T connection

Restrictions for ADSL HWICs
•ADSL HWICs can be inserted only into onboard HWIC-enabled slots on Cisco routers. Initially, these routers are the Cisco 1800 series (modular), the Cisco 2800 series, and the Cisco 3800 series integrated services routers.
•The ISDN interfaces on HWIC-ADSL-B/ST and HWIC-ADSLI-B/ST are data only.
•ATM adaption layer 2 (AAL2) is not supported.
•ADSL HWICs do not support dual latency. When the ADSL link is intended to support both voice and data traffic simultaneously, the link should be configured for either all fast-path data or all interleave data with an interleave depth of zero to insure that latency is minimized. In addition, the total supported data rate must be reduced to adjust for the reduced coding gain, which is usually present with high-latency traffic.
•The following command is not supported by ADSL HWICs:
–clock rate
•The following ISDN command is not supported by HWIC-ADSL-B/ST or HWIC-ADSLI-B/ST:
–leased-line
•Loop back functionality is not supported.

ADSL Features
Supported ADSL features are as follows:
•Provides ADSL high-speed digital data transmissions between the customer premises equipment (CPE) and the central office (CO).

•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.
ISDN Features
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.
Interface Numbering on Cisco Integrated Services Routers
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.
Table 1 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.

How to Configure ADSL HWICs
This section describes the ADSL configuration task for this feature.
Note Features configured on the ADSL HWIC must also be configured on the Digital Subscriber Loop Access Multiplexer (DSLAM) located in the CO. See the documentation for the specific DSLAM for information about configuring features.
