ADSL2+ module has been very stable for legacy WAN links. Easy to configure and performs consistently without drops.
Reliable WAN interface for branch routers. Syncs quickly and holds line quality well.
Installed smoothly and worked immediately. Good choice for maintaining older access networks.
Performance is predictable and stable. No unexpected resets or signal loss.
Solid build quality and dependable operation for Annex B deployments.
Does exactly what it should. Simple, reliable WAN connectivity.
The AR0MSLB1XA01 is a Cisco-certified 1-port ADSL2+ WAN interface module that supports Annex B and Annex J standards for high-speed broadband WAN connectivity in integrated services routers.
It supports ADSL2+ (ITU G.992.5) with fallback to ADSL2 (G.992.3) and ADSL (G.992.1), including Annex B for POTS splitters and Annex J for all-digital lines.
The module delivers downstream rates up to 24 Mbps and upstream rates up to 3.5 Mbps over ADSL2+.
It is compatible with Cisco 800 Series Integrated Services Routers that feature a modular WAN slot for single-port interface modules.
Shut down the router, insert the module into the WAN slot until it clicks, secure the latch, connect the RJ11 DSL line, and power on the router to auto-detect the interface.
Yes, the module dynamically negotiates Annex B or Annex J based on the line profile provided by your service provider.
Yes, it automatically falls back to ADSL2 and ADSL if ADSL2+ service is unavailable, ensuring uninterrupted connectivity.
It maintains optimal performance up to 5.5 km (18,000 ft) from the DSLAM over standard twisted-pair copper lines.
No, to ensure network stability, the router must be powered down before inserting or removing the module.
The module uses a standard RJ11 connector and requires category 3 or higher twisted-pair copper wiring between the DSL outlet and the router.
Yes, when integrated with Cisco IOS, the module leverages advanced QoS features to prioritize voice, data, and video traffic.
Use the 'interface ATM0' command to define the PVC, set encapsulation to 'aal5snap', and apply dialer profiles with PPPoE or PPPoA as instructed in the Cisco configuration guide.
It operates between 0 °C and 40 °C (32 °F to 104 °F) with 10%–85% relative humidity and stores at −40 °C to 70 °C.
Yes, it is CE, FCC, and UL certified and complies with RoHS and WEEE directives for global deployment.
The module is backed by Cisco's limited lifetime warranty, including next-business-day replacement support.
You can buy it from authorized Cisco resellers and partners or through the Cisco online store with full product support and licensing.
Check line status with 'show interfaces atm0', verify DSL physical-layer sync, inspect cabling, and consult your ISP for line-quality metrics to resolve connectivity problems.
