Information
As symmetric data usage in networks increases, efficient Symmetric High Bit Rate Digital Subscriber Line (SHDSL) equipment is required in both the local loop and at the customer premises. The ADTRANTM Express 6540TM SHDSL 2w/4w NTU Series provides the interface between the SHDSL network and the user’s Data Terminal Equipment (DTE) for applications such as LAN to LAN bridging, Frame Relay circuit and PABX termination.
The Express 6540 Series operates in two different system configurations:
• As a remote unit to the ADTRAN Total Access® 3000 multiservice platforms
• In pairs as a point-to-point limited distance campus configuration
The Express 6540 Series supports the following customer interfaces and operations:
• A Nx64k single service interface with a data transmission rate of 64 kbps to 2.304 Mbps in 2-wire mode (N x 64 kbps, where N=1 to 36) or 64 kbps to 4.608 Mbps in 4-wire mode (N x 64 kbps, where N=1 to 72)
• A G.703 interface with G.704 framing, with a single or multiple G.703 services with a data transmission rate from 64 kbps to 1.984 Mbps (N x 64 kbps, where N=1 to 31)
• The G.703 interface with G.704 framing will run over SHDSL in aligned mode and support simultaneous services using the Nx64k port for the second service
• A G.703 interface without framing providing a single 2.048 Mbps service (N x 64 kbps, where N=1 to 32)
The Express 6540 Series is housed in a standalone plastic case available in AC, DC, or SHDSL span/DC powered models. The front panel provides pushbuttons for operation of local and remote port loopbacks and built-in BERT testing, and has LED status indicators for data port, loopback, and BERT conditions. The front and rear panels have been designed to accommodate specific product model requirements, including four recessed pushbuttons and eight LED indicators for the front panel, and SHDSL, G.703 and/or Nx64k customer ports, local management port, and a local power connection for the rear panels.
The Express 6540 Series has the capability of being fully configured and managed by:
• A local VT100 management port
• A remote VT100 virtual terminal session via the Total Access 3000 SCU management port
• Remote NMS using the SHDSL EOC and SNMP proxy by Total Access 3000 LTU
