ith the DDS/T1 Super DSU
from Black Box, you can
connect your systems with 56kbps DDS line now, then upgrade
later to a high-speed 1.544-Mbps
T1 line.
And this CSU/DSU is ideal for
your Frame Relay connections
since you can run your DDS or T1
line into Frame Relay.
DDS lines use four wires and
although they’re capable of
supporting speeds up to 56 kbps,
DDS is actually a 64-kbps circuit
using 8 kbps for signaling.
T1 line operates at 1.544 Mbps.
This dedicated transmission line
consists of 24 DSOs each able to
support speeds of 64 kbps. Users
send data at N x 56 or N x 64 over
T1 circuits, with T1 running over
twisted-pair cables.
Since the DDS/T1 Super DSU
is SNMP manageable via SLIP
connection, network performance
can be monitored and CSU/DSUs
can be configured from any ASCII
terminal or with pushbuttons and
an LCD panel.
