The ComNet™ VDSLMS-2 consists of one each 10/100TX 8-port managed switch, one each 2-channel EoVDSL uplink modem, and a mounting chassis, to easily and inexpensively aggregate Ethernet-enabled equipment at remote field locations back to a central or head-end location over existing copper infrastructure. The VDSLMS-2 is the perfect solution for upgrading a legacy twisted copper or coaxial cable plant for use with Ethernet, when compared to the significant costs of installing new network cabling. The VDSLMS-2 automatically selects the fastest usable data rate, depending upon the copper circuit transmission distance and cable quality. Utilizing the latest generation VDSL2 technology for the fastest data rate and greatest transmission distance, any standard telephone-grade twisted copper pair, legacy serial cabling, or standard 75-ohm coaxial cable may be used, and transmission distances of up to 1.8 miles (3 km) between drops over twisted copper, or up to 1500 ft (457 m) between drops over coaxial cable are supported. The easily configured 10/100 Mbps 8-port managed switch accommodates up to six Ethernet-compatible devices, with the other two ports allocated to the 2-channel EoVDSL uplink modem. More than one EoVDSL channel may be created by connecting additional uplink modems to any of the managed switch 10/100TX ports. Plug-and-play operation, automatic learning, negotiation, and crossover detection are supported. Full network management, including IGMP snooping and Spanning Tree protocols are provided, and ensure the smooth flow of data traffic even when multiple video sources are added and dropped over the network. Designed for long-term reliable operation in harsh industrial environments, the VDSLMS-2 may be deployed in most out-of-plant installations, such as those found in intelligent transportation systems and factory automation/control applications. The chassis is provided for mounting the managed switch and uplink modem onto one common platform, creating a compact, easy to integrate, self-contained system. The managed switch and uplink modem may also DIN-rail mounted by the addition of a ComNet model DINBKT1 adaptor plate.
- Designed as a very low-cost and simple to implement solution for drop-and-repeat Ethernet-over-copper transmission circuits
- Provides greater flexibility and the same functionality as drop-andrepeat EoVDSL managed switches costing considerably more
- Latest generation VDSL2 technology for fastest data rate and greatest transmission distance
- Modular, Field-Expandable Design: Supports more than one EoVDSL channel by adding additional 2-channel EoVDSL uplink modems
- Uses telephone-grade twisted copper pair, legacy serial cabling, or standard 75? coaxial cable circuits to create a drop-and-repeat/point-to-multipoint Ethernet-based network
- Ideal for those applications where an existing installed base of copper wiring is available
- Automatically selects fastest usable data rate, depending upon the copper circuit transmission distance and cable quality
- Transmission Distances of up to 1.8 miles (3 km) between drops over twisted copper, or up to 1500 ft (457 m) between drops over coaxial cable
- Designed for installation in harsh out-of-plant/unconditioned industrial or roadside operating environments (-40º to +75º C ambient). Fully compliant with the environmental requirements of NEMA TS-2 for Traffic Signal Control Equipment
- Natural convection cooling; no fans or air filters for the highest level of reliability, and zero periodic maintenance
- 120/240 VAC power supply included. The VDSLMS-2 may also be operated from an external source of +12 to +27 VDC
