| The
JUPITER 2560 is a high-speed, Synchronous and Asynchronous
Network Termination Unit (NTU). It fully complies with
ANSI T1.601 utilizing 2B1Q line coding and echo cancellation
techniques to provide a full duplex operation at data
rates ranging from 9.6 Kbpsto 128Kbps over a 2-wire unconditioned
line. The operating range will be up to 7.8 Km over a
24 gauge 2-wire twisted-pair. It also provides diagnostic
capabilities, such as analog loopback, digital local
and remote loopback, and BER test with 511 test pattern
for troubleshooting both the NTU and the transmission
line.
The
JUPITER 2560 allows connection to a variety of DTE
interface such as: V.35, EIA-530, RS-232D and X.21/V.11.
Applying an optional 64Kbps codirectional G.703 interface,
it can easily connect to Channel-Bank for utilizing
CSU/DSU services. The sub-rate functions comply with
ITU-T X.50 division 3 and can also provide 9.6, 19.2
and 38.4 Kbps data services for the Digital Data
Network (DDN).
