Deutsche Telekom AG has switched all connections to ALL-IP since 2018. In this regard, we have successfully tested various ALLNET modems in the Telekom test center. Our modems are compatible with all line variants.

Power over Ethernet (PoE) is a technology to distribute power and data over a single network cable. To use PoE, you need devices offering the functionality.

With PoE PD technology, you can create a small network using a single patch cable and operate all end devices, provided they support PoE.

In the first step, it is important to understand what Powerline is and how it works. In short, Powerline is a technology that uses existing power lines to establish a network for data transmission. The maximum data transfer rate is currently at 1200Mbit with a maximum distance of approx. 300 meters.

G.hn provides the opportunity to use all possible transfer methods within a household to transfer data. It is irrelevant whether electricity, telephone, coax or network cables are used. So, the new home grid standard offers the ability to use different transmission methods within a building to simplify the usage and management of networks.

VDSL is a DSL technology that offers higher data transfer rates by using the standard 2-wire telephone lines than the ADSL or ADSL2+ standards. The ALLNET VDSL2 components are perfect for The ALLNET VDSL2 Master DSLAM / Switch or Master Modem can realized in conjunction with the ALL126AS2 VDSL Slave a leased line via a simple 2-wire copper cables for a distance of up to 2.5 kilometers.

PTP IEEE 1588 (Precision Time Protocol) is a network protocol for highly accurate time synchronization in computer networks. It enables nanosecond-level precision by aligning master and slave clocks. Common applications include telecommunications, industrial automation, and financial markets where precise time synchronization is critical. PTP uses messages like Sync, Follow_Up, Delay_Req, and Delay_Resp for synchronization.

DHCP Snooping is a security feature in networks that blocks unauthorized DHCP servers. Switches monitor DHCP traffic and differentiate between trusted and untrusted ports. Only trusted ports are allowed to send DHCP responses. This prevents Man-in-the-Middle attacks like DHCP spoofing. Additionally, a database of legitimate IP-MAC bindings is created to enhance network security.

A VLAN (Virtual Local Area Network) is a logical, separate network within a physical network. It allows network segmentation to group devices regardless of their physical connection. VLANs enhance security, performance, and management flexibility by reducing broadcast domains and isolating traffic. Common applications include separating departments, prioritizing traffic, and improving network security.

Dynamic ARP Inspection (DAI) is a security mechanism that prevents ARP spoofing attacks in networks. It inspects incoming ARP packets for validity by comparing them against a DHCP snooping database or manually created binding entries. Only valid ARP packets are forwarded. DAI protects against attacks where an attacker sends fake ARP messages to intercept or redirect network traffic.
