Data Format

The data format selection controls whether an async-to-sync conversion is performed. (Data is always transferred synchronously between the two CSU/DSU’s)

SW1-7

Data Format

On

Asynchronous

Off

Synchronous

Note1: The async rate of 57.6 kbps is supported at the 56kbps line rate, provided the DTE equipment transmits two stop bits. Two stop bits can be configured on most DTE equipment. This extra stop bit reduces the DTE’s effective data rate by a few percent to allow synchronization with the 56kbps line speed.

Note2: Lower speed asynchronous data can be transmitted on synchronous circuits by simple over-sampling. To do this, leave Data Format set to synchronous. Make sure the CSU/DSU’s sync data rate is at least 4 times more than the async data rate you wish to send.

DSR Loop Status

The behavior of the DSR output during performance of a local loop can be controlled.
