Parity
After transmission, many Voice Mail systems send a parity bit in order to catch transmission
errors. A parity check is the Voice Mail process for detecting if any data bits have been altered
during transmission. When the transmitting device frames a word (byte), it counts either the
number of 0’s or 1’s in the data bits and then adds a parity bit that corresponds to whether or
not the count of the data bits was even or odd. The receiving device also counts the data bit 0’s
or 1’s as it receives them and then compares its computation to the parity bit. If a transmission
error is detected, a flag can be set and retransmission may be requested.
If you set Parity to No, no parity check will be performed.
If you set Parity to Even, the parity bit will be set at 0 if the number of 1s in the data bits is
even and set to 1 if the number of 1s is odd.
If you set Parity to Odd, the parity bit will be set at 1 if the number of 1s in the data bits is
even and set to 0 if the number of 1s is odd.
CTS/RTS Flow Control
CTS/RTS Flow Control refers to a protocol that regulates the flow of data between a computer
and a serial device by means of the CTS and RTS signals between them. CTS signals a Clear
To Send. RTS signals a Request To Send.
