Módem ALLNET ALL126AS3

ALLNET ALL126AS3 is a VDSL2 CPE modem designed for use on existing two‑wire copper lines, supporting VDSL2 up to 100 Mbit/s (actual throughput depends on line length, up to approx. 2500 m). The device interoperates with a CO VDSL2 master (for example ALL126AM2) and supports DPBO (Downstream Power Back Off). It uses a Lantiq VRX chipset, complies with IEEE 802.3/802.3u/802.3z standards, and is CE certified. The compact unit has a typical power consumption of 6.7 W and is intended to deliver high‑speed services such as IPTV, VOD, videoconferencing and VoIP over standard copper telephone cabling.

Advantages

The ALLNET ALL126AS3 provides VDSL2 connectivity on existing copper infrastructure, enabling high bandwidth over short to medium distances while remaining compact and energy efficient. Support for DPBO improves downstream power management and the modem’s compliance with common Ethernet standards ensures compatibility with typical network equipment. Its small dimensions and modest power draw make it suitable for installation in residential or small office environments.

Suitable for

• Delivery of high‑speed Internet services over existing copper lines
• IPTV and video on demand to homes or apartments
• VoIP and advanced telephony services in small offices or residences
• Extending FTTP deployments where fiber reaches a building and copper continues to individual units

How to use

Install the ALLNET ALL126AS3 at the customer premises and connect it to the existing copper telephone pair that links to the central office VDSL2 master (CO) device. Connect the modem to the local network or a single LAN device using Ethernet (observing IEEE 802.3 family compatibility). Configure the modem according to operator provisioning or the supplied configuration guide; typical steps include setting line parameters, WAN/VLAN settings and authentication as required by the service provider. Ensure proper ventilation and mount the unit in a dry, accessible location.

Recommendations

Place the modem as close as possible to the incoming copper line termination to maximise achievable bandwidth; verify line quality and length to estimate attainable speeds. For deployments alongside fibre rollouts, use the ALL126AS3 to bridge from a building’s fiber termination point to individual copper‑served units. Follow operator provisioning instructions to ensure interoperable settings and enable DPBO if supported by the network.
