The Cisco HWIC-ADSL-B/ST is a 2-port High-Speed WAN Interface Card that provides one ADSLoPOTS port and one ISDN BRI S/T port for Cisco ISR G2 routers.
The HWIC-ADSL-B/ST is compatible with Cisco ISR 1900, 2900 and 3900 Series routers that feature HWIC slots and run Cisco IOS.
This module offers one ADSL over POTS interface and one ISDN BRI S/T interface enabling simultaneous broadband and digital voice connectivity.
The card supports ADSL, ADSL2, ADSL2+, and Annex A/B profiles, delivering downstream rates up to 24 Mbps and upstream rates up to 3.5 Mbps.
The ISDN BRI S/T port supports two 64 Kbps B-channels for a combined maximum throughput of 128 Kbps.
Power off the router, insert the HWIC-ADSL-B/ST into an available HWIC slot, secure it with the retaining screw, then power on and verify card recognition in the IOS CLI.
No external power is needed; the card draws its operational power directly from the hosting Cisco router’s HWIC slot.
Yes. The HWIC-ADSL-B/ST supports concurrent use of both ports for redundancy or load-sharing in multi-access deployments.
Cisco IOS Software Release 15.1(4)M or later is recommended to enable full support for ADSL2+ and ISDN BRI features.
Use the CLI commands 'interface bri0' followed by 'isdn switch-type basic-ni' and 'encapsulation ppp' or 'ppp multilink' to configure your ISDN session.
Typical deployments include small branch office broadband backup, remote teleworker connectivity, and ISDN voice/fax termination over legacy networks.
The HWIC-ADSL-B/ST adds an ISDN BRI S/T interface alongside ADSLoPOTS, whereas the HWIC-ADSL-LATE provides only single-port ADSLoPOTS connectivity.
Use 'show interface atm0' and 'show interface bri0' to verify line status, check DSL sync stats, and inspect event logs for error counters and layer-1 failures.
Cisco offers a one-year limited hardware warranty with options to extend support via Cisco SMARTnet for software updates and 24×7 technical assistance.
