IntroductionThe EOC-20 is Multiplexer Unit for EoCNA (Ethernet over Coax Network Alliance) solution that efficiently extends 10/100 Ethernet circuits to over 900 meters(2,952feet) at 112Mbps using existing coaxial cable. The EOC-20 will allow Ethernet connectivity in existing facilities without pulling extra cable. This is perfect solution for hotel or Multi-Dwelling Units where existing CATV coaxial cable already exists and high-speed Ethernet communications are required for Internet and/or IPTV. The EOC-20/21 is used with Coaxial cable to extend Ethernet connectivity over existing CCD/CATV grade Coaxial cable.</p> <p>1.1 Key FeaturesHigh-Speed, up to 160Mbps communications link over existing Coaxial Cable, Asymmetrical on EoCNA 112Mbps@ up to 900 meters(2,952feet), reach down to 32Mbps @ about 1.2Km(4,000feet) Operates transparently to high layer protocols such as TCP/IP Auto-MDIX and Auto-sensing 10Base-T or 100Base-TX and Full or Half-Duplex on the Ethernet port Web based configuration or provisioning via TFTP configuration download Status LEDs for simple monitoring of the device and connection status</p> <p>1.2 SpecificationsNetwork Standards ITU G.9954Ethernet Over Coaxial Network (EoCNA) IEEE802.3 10BASE-T, 10Mbit/s IEEE802.3u 100BASE-TX, Fast Ethernet at 100Mbit/s, Auto-negotiation IEEE802.3x Full Duplex and Flow Control IEEE802.1Q 802.1Q tag-based VLANs IEEE802.1p Multi-Priority assignment, Differential queue weight, Port-based and queue-based rate limiting Multicast Applications: Supports IGMPv1/v2 snooping.

Extend LAN connectivity to a remote site or between buildings Connect Ethernet between different rooms over existing home Coaxial infrastructure Connect new controller technology on the factory floor using existing cable Extend Ethernet connectivity from a backbone network to an isolated location via Coaxial wire Transmit Video and traffic controller information over existing Coaxial wire</p> <p>2. VLAN (Virtual Local Area Network)Virtual LAN (VLAN) is defined as a group of devices on one or more LANs that are configured so that they can communicate as if they were attached to different wire, when in fact they are located on the same LAN segment. Because VLAN is based on logical instead of physical connections, it is extremely flexible. The IEEE 802.1Q defines the operation of VLAN bridges that permit the definition, operation, and administration of VLAN topologies within a bridged LAN infrastructure. VLAN architecture benefits include: 1. Increased performance 2. Improved manageability 3. Network tuning and simplification of software configurations 4. Physical topology independence 5. Increased security options As EOC (Ethernet over Coax) links are deployed more and more extensively and popularly, the technology embraces the implementation of VLAN (VLAN tagging and untagged) over Coaxial links and, hence, it is possible to be a requirement of ISPs. We discuss the implementation of VLAN only for bridge mode operation, i.e., the VLAN spreads over both the CO and CPE sides, where there is no layer 3 routing involved.</p> <p>2.1 Specification1. 2.
