The WIC-1ADSL module offers excellent ADSL connectivity. It ensures stable, fast internet access, improving the overall performance of our network.
The Cisco WIC-1ADSL is a single-port WAN Interface Card that enables ADSL broadband connectivity on compatible routers for cost-effective Internet access.
The WIC-1ADSL is supported on Cisco Integrated Services Routers (ISR) and Cisco 2500, 2600, 3600, and 3700 series routers with WIC expansion slots.
It supports ITU G.992.1 (ADSL), G.992.3 (ADSL2) and G.992.5 (ADSL2+) standards for flexible deployment and backward compatibility.
The WIC-1ADSL delivers up to 8 Mbps downstream and 832 Kbps upstream, depending on line conditions and service provider provisioning.
Yes, it maintains full backward compatibility with legacy ADSL networks to ensure seamless integration with existing DSL infrastructure.
Yes, it supports both ADSL2 and ADSL2+ for enhanced bandwidth and performance over standard ADSL connections.
The module features a single RJ-11 connector for the ADSL line and interfaces directly with the router’s internal backplane.
Power off the router, insert the WIC-1ADSL into an available WIC slot, secure the card with the chassis screw, then power the router back on.
No additional software is required, but ensure your router runs a Cisco IOS release that recognizes ADSL WAN interface cards.
In IOS, enter interface atm0/0, set encapsulation with “encapsulation aal5snap,” and configure PPPoE or PPPoA dialer profiles as needed.
No, the WIC-1ADSL is not hot-swappable; you must power down the router before inserting or removing the card.
The module draws power directly from the router’s backplane and does not require any external power sources.
Use “show controllers atm 0/0” for signal diagnostics, verify RJ-11 cabling and check your service provider’s line status for any outages.
It supports PPPoA, PPPoE, MPoA and standard CHAP/PAP authentication to secure your broadband link.
Yes, it can carry VoIP traffic over the DSL link but requires a separate VoIP gateway or voice-enabled router for call processing.
Cisco offers a limited lifetime warranty and provides technical assistance through the Cisco TAC with a valid support contract.
