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 2
15
-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.
