MT56DSU-R Owner's Manual

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.
