Line (SHDSL) technology to transport data over a single copper loop. The Express 6530 interfaces between the incoming ITU G.991.2 (SHDSL) leased-line service and the customer’s Data Terminal Equipment (DTE), providing solutions for LAN-to-LAN bridging, Frame Relay, and/or PBX termination.

The Express 6530 is a locally powered standalone unit which contains an integrated Data Service Unit (DSU), eliminating the need for a separate DSU. The Express 6530 interfaces to a customer’s G.703, V.35, or X.21 interfaces and can be provisioned to support simultaneous G.703 and Nx64 services. The SHDSL interface is designed to operate from 192 kbps to

2.304 Mbps in 64 kbps increments or from 3 to 36 time slots, with each time slot representing 64 kbps. The SHDSL time slots can be multiplexed to the G.703 and/or the Nx64 interfaces. The maximum number of time slots that can be directed toward the G.703 interface is 32 (2.048 Mbps), while the Nx64 can support 36 (2.304 Mbps). A block diagram of the Express 6530 functionality is illustrated in Figure 2.

The Express 6530 can be deployed in pairs for a local campus application or to an LTU located in a Central Office. The Express 6530 can be locally or remotely provisioned with local provisioning being accomplished through the V.28 control port using a dumb terminal or PC with a terminal emulation program. The Express 6530 can be remotely provisioned by another Express 6530 or an ADTRAN SHDSL LTU. The Express 6530 can initiate and respond to local and remote loopbacks and has an internal 215-1 pseudorandom test pattern for bit error testing. Front panel-mounted LEDs and pushbuttons provide interface and test status as well as the initiation of a remote or local loopback.
