HWIC-1ADSL-M Use Case
Remote Branch Office Connectivity in Underserved Regions
A regional retail chain deploys the HWIC-1ADSL-M-1-port ADSL HWIC w/Annex M on its ISR4000 series routers to connect a rural branch lacking fiber or cable. Leveraging Annex M’s higher upstream (up to 3.3 Mbps), the store maintains secure IPsec VPN tunnels to headquarters for real-time POS data synchronization, inventory management and cloud-based reporting. Outcome: reliable high-speed WAN at a fraction of leased-line cost, enabling centralized operations, faster order fulfillment and 99.9% uptime compliance.
Enhanced VoIP & Video Conferencing for SMBs
A professional services firm integrates the HWIC-1ADSL-M-1-port ADSL HWIC with Annex M into its ISR3000 router to serve as primary Internet access for VoIP phones and HD video conferencing. By taking advantage of Annex M’s asymmetric uplink boost, the company ensures consistent upstream bandwidth for SIP call signaling, QoS-prioritized voice packets and multi-party video streams. Outcome: crystal-clear voice/video quality, reduced jitter/latency and a 30% improvement in remote collaboration productivity without upgrading to pricier business fiber.
Automated Failover & Business Continuity Solution
An enterprise IT team configures the HWIC-1ADSL-M-1-port ADSL card as a secondary WAN interface on a Cisco ISR2900 router. In the event of primary MPLS or cable Internet failure, Embedded Event Manager scripts trigger automatic route failover to the Annex M ADSL link. This seamless switch preserves critical services—ERP access, VoIP trunking and cloud backup—while alerting network operators via SNMP traps. Outcome: near-zero downtime, improved SLA adherence and simplified disaster-recovery orchestration with existing copper infrastructure.

Questions & Answers
Q
What is the Cisco HWIC-1ADSL-M?
A
The Cisco HWIC-1ADSL-M is a High-Speed WAN Interface Card (HWIC) that provides a single-port ADSL connection with Annex M support for Cisco ISR routers, enabling enhanced upstream bandwidth for small-to-medium business deployments.
Q
What are the key features of the HWIC-1ADSL-M?
A
Key features include Annex M support for up to 3.3 Mbps upstream, ATM-based ADSL connectivity up to 24 Mbps downstream, support for multiple PVCs, TR-070 provisioning, and seamless integration with Cisco IOS.
Q
How does Annex M improve ADSL performance?
A
Annex M reallocates upstream/downstream tones to boost upstream bandwidth up to 3.3 Mbps (compared to 1 Mbps on Annex A), ideal for applications requiring higher upload speeds like VoIP and cloud backups.
Q
Which Cisco routers are compatible with the HWIC-1ADSL-M?
A
The HWIC-1ADSL-M is compatible with Cisco 1841, 2801, 2811, 2821, 2851, 2911, 2921, 2951, 3925, 3945, 4321, 4331, 4351, 4431, and 4451 ISR routers running Cisco IOS 15.x or later.
Q
What data rates does the HWIC-1ADSL-M support?
A
It supports downstream ADSL rates up to 24 Mbps and upstream rates up to 3.3 Mbps under Annex M, with automatic rate adaptation based on line conditions.
Q
How do I install the Cisco HWIC-1ADSL-M in my router?
A
Power off your ISR router, remove the protective slot cover, insert the HWIC-1ADSL-M into an available HWIC slot, secure it with the retention screw, and power on the router.
Q
How do I configure ADSL settings on the HWIC-1ADSL-M?
A
Use Cisco IOS commands in global configuration mode: specify the ATM PVC (e.g., 'encapsulation aal5snap'), set VPI/VCI values, select Annex M if required, and apply dialer or static IP configuration.
