Product description

The SHDTU03bA-31T-AD is an exceptional G.shdsl.bis modem designed to simultaneously transport both T1 and Ethernet interfaces over copper wires. Modem can operate in 2 or 4 wire mode, providing either 5.7Mbps (or 11.4Mbps if 4 wire) of bandwidth. G.shdsl.bis is one of most resilient DSL standards, and depending on the quality of the copper circuit it can help extend T1 and Ethernet service up to 5.5 miles away. Modem is using the leading TDM technology in implementing DSL transport and provides mechanism to guarantee bandwidth for the T1 connection while allocation all extra available payload for the Ethernet circuit. The SHDTU03bA-31T-AD has dual redundant power supplies for AC (90-240V) and DC (36-72V) power inputs. Management is available via serial console, IP or the built-in LCD panel and keypad.
