The Allnet ALL-MC116SV-VDSL2 is an unmanaged VDSL2 bridge modem designed for data transmission over a single copper cable pair. It is based on the G.993.2 VDSL2 standard technology and supports VDSL profiles 8a, 8b, 8c, 8d, 12a, 12b, and 17a. The device is specifically developed for use in point-to-point connections, particularly for integration into DSLAM systems of telecommunications providers, ISPs, and in hospitality environments such as hotels or hospitals. It enables the extension of LAN networks over copper lines where fiber optic or Ethernet connections are not available. The support for Vectoring according to ITU-T G.993.5 enables improved signal transmission and higher bandwidths, especially in environments with multiple parallel lines. The modem is compatible with standard VDSL2 connections up to 100 Mbit/s.

Applications
This modem is suitable for use in buildings, hotels, hospitals, or other facilities located outside the reach of Ethernet or fiber optic connections. It serves as a bridge between a DSLAM and a local network, with data transmission occurring over a copper cable pair. The unmanaged design means that configuration of VLANs, bandwidth control, or similar network functions is not possible. Therefore, the devices are intended for simple, direct connections without additional network configuration.

Functions and Features in Detail
The device features two 10/100/1000Base-T Ethernet ports (RJ45) and an additional 1000Base-X SFP slot, enabling integration of fiber optic modules. This provides flexibility for network expansion, such as connecting to existing fiber optic infrastructures. Support for Jumbo Frames with an MTU of 2K bytes on the VDSL side improves data transmission efficiency, especially for large data packets. The integrated surge protection circuit protects the device from voltage spikes at the VDSL interface.

Technology Explained Simply
The VDSL2 technology uses frequencies in the copper cable to transmit data over short to medium distances. The Vectoring function coordinates signals across multiple lines to reduce interference and increase transmission rates. DMT modulation (Discrete Multi-Tone) enables efficient use of the frequency spectrum. The device operates with a supply voltage of 12 V DC, provided via an included power supply (AC adapter). Typical power consumption is 3 W.

Compatibility and Accessories
The modem is compatible with IEEE 802.3ab, IEEE 802.3u, and IEEE 802.3z standards. It supports G.INP as well as UPBO and DPBO. Available accessories include a HUT rail adapter (DIN rail adapter) and a replacement power supply (12 V/2.0 A). Another modem in the series, the ALL-MC116V2, is available as a point-to-point modem with a maximum range of 3 km and up to 160 Mbit/s. Installation is carried out in a metal housing with dimensions 124 x 93 x 27 mm.

Installation and Mounting
The device can be connected directly, with power supplied via the included power supply. The VDSL interface is available via an RJ-11 connector or a terminal block. Installation does not require special network configuration, as it is an unmanaged device. LED indicators (LAN E1/E2: Act/Link, SFP port: Link, Line: Act/Link, System: PWR) provide status indication.

Operational Advantages
The modem offers a cost-effective solution for extending networks over existing copper lines. The combination of VDSL2, Vectoring, and an SFP slot enables a flexible and scalable infrastructure. Its compact design and optional DIN rail mounting facilitate installation in server rooms or enclosures. Operating temperature ranges from 0 to 50 °C, storage temperature from -20 to 70 °C. Humidity is 10 to 90 % (non-condensing). The devices are CE-, FCC-, and RoHS-compliant.

The delivery includes the modem ALL-MC116SV-VDSL2, an external power supply, and an operating manual.
