DTE Interface Configuration Options
Parity Bit: None
Nxt None Even Odd Mark Space
Parity Bit. Determines type of parity bit. The parity of the DTE must match the parity of the modem. Parity options include
None, Even, Odd, Mark, or Space.
None – No parity bit is used. This is the default for Async mode.
Even – Parity bit is set so that total number of 1’s in data bits plus parity bit is even.
Odd – Parity bit is set so that total number of 1’s in data bits plus parity bit is odd. This is the default for Sync mode.
Mark – Parity bit is always set to 1. Only valid if #Data Bits configuration option is set to 7.
Space – Parity bit is always set to 0. Only valid if #Data Bits configuration option is set to 7.
The factory default is None.
NOTE: If the DTE Dialer Type configuration option is set for AT or V.25bis Async, then the total character size must
equal 10 bits (see DTE Dialer configuration options group). Total character size consists of a start bit, number of
data bits, parity bits, and stop bits. V.25bis Async must use 7 data bits with even parity and 1 stop bit. The total
character size for Error Control mode or Buffer mode must be 10 bits or less. The total character size for Direct
mode must be 11 bits or less.
AT prefix determines parity of the character.
#Stop Bits: 1
Nxt 1 2
Number of Stop Bits. Selects 1 or 2 bits to signal the end of a character.
The factory default is 1.
NOTE: If the DTE Dialer Type configuration option is set for AT or V.25bis Async, then the total character size must
equal 10 bits (see DTE Dialer configuration options group). Total character size consists of a start bit, number
of data bits, parity bits, and stop bits. V.25bis Async must use 7 data bits with even parity and 1 stop bit. The
total character size for Error Control mode or Buffer mode must be 10 bits or less. The total character size for
Direct mode must be 11 bits or less.
AT prefix determines the number of stop bits via autobauding.
