Overview
The Model 3550 DSU is designed for desktop
operation and is delivered ready to connect to the
network. It is configured as a tributary DSU for operation
at 9.6 kbps on a multipoint circuit.
If the unit was ordered with a TDM/Flex installed,
Ports 1 and 2 are configured for 9.6 kbps operation, and
configured as a digital sharing device (DSD). Both ports
are configured for EIA-232 operation, rather than V.35
operation. Refer to the MUX (Port) option set tables in
Chapter 5 to change this configuration on a port-by-port
basis.
Installation consists of the following steps, which
should be performed in the order listed.
Physical installation
Hardware straps
Electrical connection
Network diagnostic connection
Software configuration
DDS network (or LADS) connection

Dial (or PSTN) network connection if a DBM is
installed, or if using an external dial backup unit
(DBU)
DSU DTE connection
Verification testing
Although the Model 3550 DSU is designed for desk or
table-top operation, you can order an ACCULINKr
3100 Series CSU wall-mount adapter if you want to
mount the DSU on a wall, an equipment shelf, a 19-inch
RS-310-C or 23-inch AT&T DATAPHONEr equipment
cabinet. Refer to Appendix F
Before You Begin
Your installation site should be clean, well-lighted,
well-ventilated, and free from environmental extremes.
A dedicated grounded ac outlet that is protected by a
circuit breaker should be installed within 6 feet of the
DSU's planned location. The outlet should be capable of
supplying 90 to 132 Vac 60 Hz (U.S. and Canada). The
circuit must be capable of supplying a minimum of
2 amperes at 115 Vac. Refer to the
