3.2.9

DSR Forced On

When this option is enabled, the MT56DSU-R forces the DSR signal
on continuously regardless of the condition of the received DDS
signal (OOS or Test). The permanent DSR signal is used to
eliminate momentary link interruptions that may be interpreted by
the DTE as a communications channel failure.
With this option disabled, the DSR is handled as described in the
“System Status” section earlier in this chapter.
The default for this function is DSR Forced On. (Refer to Chapter 2
for changing the default DIP switch settings.)
3.2.10

Async Word Length

This option allows you to select the word length to be used by the
MT56DSU-R for asynchronous data transmissions. The Async Word
Length selections are 9-, 10- and 11-bits. The async word length
selected here must match the async word length set at the DTE.
The default for this function is a 10-bit async word(1 start, 8 data, no
parity, 1 stop bit) length. (Refer to Chapter 2 for changing the default
DIP switch settings.)
3.2.11

Normal/Diagnostics

The default for this option is “Normal” (standard CSU/DSU
operation). For information on the “Diagnostics” selection, refer to
Chapter 4.
