ADTRAN NetVanta 838T
Eight-Port, SHDSL EFM Ethernet NTU

Overview:

Eight-Port, SHDSL EFM Ethernet NTU

The NetVanta 838T is a Carrier Ethernet Network Termination Unit (NTU) that terminates up to eight e.SHDSL copper pairs. Four 10/100 Ethernet ports are provided for customer use. The NetVanta 838T 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. The NetVanta 838T is designed for LAN, WAN and MetroEthernet extension 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 auto line detection, which enables synchronization with data rates from 192 Kbps to 15 Mbps without operator intervention.

In the event that a single loop fails, the NetVanta 838T will continue to operate on the remaining loop, providing additional resiliency. Once the failed loop is operational again, the NetVanta 838T 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 customer premises installations. It can be wall or rack mounted depending on customer preference. When wall mounted, the NetVanta 838T only occupies an eight-inch by 12-inch area of the customer's telephone wiring closet. For rack mount installations, custom 19-inch rackmount shelves are available.
