The ADTRAN DSU III AR™ is a technologically advanced, high
performance data service unit/channel service unit (DSU/CSU). This unit
provides a reliable interface between the digital data service (DDS) or 4-wire
Switched 56 (SW56) network and the customer’s data terminal equipment (DTE). The
unit is an all-rate DSU/CSU supporting synchronous and asynchronous data rates
on the primary channel and asynchronous data rates on the secondary channel. The
synchronous primary channel rates supported are 2.4, 4.8, 9.6, 19.2, 38.4, 56,
and 64 Kbps. Asynchronous data rates supported are 2.4, 4.8, 9.6, 19.2, 38.4 and
57.6 Kbps. Secondary channel data rates of 75, 150, 300, 600, 1200, and 2400 bps
are offered depending upon the primary channel rate.
The DTE interface can be selected as either EIA-232 or V.35 for
all data rates. The secondary channel interface is EIA-232 and is accessed
through a separate connector. Additional features of the DSU III AR
include a DTE-to-service rate matching feature for both dedicated and switched
modes, as well as various anti-streaming time-out values, to disable streaming
terminals on a multi-point circuit. Private networks and modem tail circuits are
accommodated through clocking/timing options.
In the 4-wire SW56 mode, dialing options include manual dialing, redialing,
and dialing
of stored numbers. Dialing over the DTE interface is supported by use of an AT
command
set or the V.25 bis in-band dialing protocol. The unit responds to standard
loopback commands from the telephone company central office. In addition, the
user has several built-in test capabilities. These include V.54 remote loopback,
2047 and 511 BERT test patterns, and four DDS stress patterns results of which
are displayed on a two-line by 16-character LCD display and seven LEDs). The
standalone unit’s front panel keypad
supports setup, selection of test modes, local and remote configuration, manual
dialing,
automatic dialing from stored numbers. The rackmount unit can be configured
through the Smart 16/16e shelf controller card, from a local/remote VT100
terminal from an ADTRAN DATAMATE. The DSU III can also be configured using AT or
V.25 bis commands. A DC version of the standalone unit is also available. The
DSU III AR DC supports all the functionality of the DSU III AR, except secondary
channel.
