NetVanta 838 Enhanced Protection SHDSL EFM - 1172839G1


The NetVanta® 838 Enhanced Protection (EP) is a Carrier Ethernet Network Termination Unit (NTU) that terminates up to eight e.SHDSL copper pairs. Two 10/100 Ethernet ports are provided for customer use. The NetVanta 838 EP is designed for cost-effective deployment of voice and data services to small- and medium-sized businesses, supporting bandwidth indoors of up to 120 Mbps. However, typical deployments using outside plant copper for extended distances will be closer to 16 Mbps (2 Mbps per loop) service offering. The NetVanta 838 EP is designed for LAN, WAN and MetroEthernet extension in uncontrolled environments such as cell sites as well as supporting Voice over IP (VoIP) applications with voice, video and data traffic. Enterprise customers, as well as integrated communications providers like CLECs, ILECs, and ISPs, will benefit from this intuitive, easy to install, plug-and-play unit. A key feature of this unit is the enhanced lightning protection on the metallic interfaces which allows survivability up to 20kV of ground potential rise.

Redundancy and Resiliency

In the event that a single loop fails, the NetVanta 838 EP will continue to operate on the remaining loop, providing additional resiliency. Once the failed loop is operational again, the NetVanta 838 EP will automatically detect its availability and will auto-recover to the original configuration. The EIA-232 craft port enables local access for configuration and status information. The SHDSL Ethernet over Copper provides carriers a management channel to remotely configure and collect status information. The compact design provides safety and reliability required for outdoor installation due to the Euro Block termination for improved isolation on the physical interface and the environmental alarming capabilities. It can be wall or rack-mounted depending on customer preference. When wall-mounted, the NetVanta 838 EP only occupies a 12 inch by 19-inch area of a GR-487 compliant outdoor enclosure. For rack-mount installations, custom 19-inch rackmount shelves are available.
