Planet - VC-234 - 100/100 Mbps Ethernet (4-Port LAN) to VDSL2 Bridge - 30a profile
Product Overview
PLANET VC-234 is a 4-port Ethernet-to-VDSL2 bridge featuring 4 × 10/100BASE-TX RJ45 ports and dual RJ11 interfaces for VDSL and POTS services. It supports VDSL2 Profiles 17a and 30a, delivering up to 100Mbps symmetric throughput at short range and extended connectivity up to 1.4 km. The unit includes a built-in POTS splitter, selectable CO/CPE modes, and a 0.8Gbps switching fabric.
Key Configuration
- • LAN ports: 4 × 10/100BASE-TX RJ45 (auto-negotiation, auto-MDI/MDI-X)
- • VDSL port: 1 × RJ11 (VDSL connection)
- • Phone port: 1 × RJ11 (POTS connection with built-in splitter)
- • DIP switch: CO/CPE mode, fast/interleaved, 17a/30a profile, target SNR
- • Switch fabric: 0.8 Gbps; throughput: 0.59 Mpps; MAC table: 2K
- • Dimensions: 155 × 86 × 26 mm; weight: 368g
Key Features
Built-in POTS splitter allows voice and data to share the same telephone line without rewiring. Supports selectable CO/CPE modes, VDSL2 17a and 30a profiles, VLAN tag transparency, and hardware IGMP snooping for multimedia traffic. Plug-and-play design with diagnostic LEDs, operating from 0–50°C and certified to FCC Class A and CE standards.
Technical Context
The VC-234 extends Ethernet over existing telephone wiring using VDSL2 technology, providing high-speed connectivity without new cabling. It supports distances up to 1.4 km, includes a built-in POTS splitter for simultaneous voice and data, and offers selectable CO/CPE operating modes for point-to-point deployment.
Installation Notes
Compact unit measuring 155 × 86 × 26 mm and weighing 368g, designed for operation in temperatures from 0°C to 50°C. Powered by a 5V DC adapter with maximum power consumption of 7.2W. Supports VDSL transmission over AWG24 or better telephone cabling up to 1.4 km, with a 4-position DIP switch for mode, profile, and line configuration. Includes an integrated POTS splitter for simultaneous voice and data services over the same copper pair.
