reconfigured) for EIA-232 or V.35 operation.
Refer to Chapter 5, Configuring the Unit. Chapter 5
fully explains the Opts subbranch, and provides an
example of changing configuration options.

Reconfiguring a TDM/Flex Port
The Connecting the DSU to a DTE section of
Chapter 2 tells you how to connect Port 2 if your DSU is
equipped with a TDM/Flex.
With the TDM/Flex option, you can configure each
port (Port 1 or Port 2) independently (e.g., one port can be
configured for EIA-232 operation while other port is
configured for V.35 operation – or vice versa).
The unit is shipped with both ports configured for
EIA-232 operation.
