Currently, only twenty X.50-compliant 8-bit envelopes are supported. Three types X.50-compliant 8-bit envelopes are available, that is, twenty X.50-compliant 8-bit envelopes (S bit loopback), twenty X.50-compliant 8-bit envelopes(S bit = 0), and twenty X.50-compliant 8-bit envelopes (S bit = 1).

NOTE:
This parameter is configurable only when Serial Port Rate (bps) is set to an X.50 D3 sub-rate.

Synchronous

Yes, No

Specifies the working mode of a board.

NOTE:
This parameter is configurable only when Serial Port Rate (bps) is set to a sub-rate.

Asynchronous Character Length(bits)

6, 7, 8, 9, 10, 11

Specifies the asynchronous character length for a board working in asynchronous mode. Asynchronous character length = Number of start bits + Number of valid data bits + Number of parity check bits (optional) + Number of stop bits.

Generally, the length of an asynchronous character is 10, which consists of one start bit, eight data bits, and one stop bit. The lengths of four parts in an asynchronous character are variable.

When a port works at a sub-rate of 9.6 kbit/s and the length of its asynchronous character is 10 bits, the rate of the port displayed on a tester is 7680 bit/s (7680 bit/s = 9600 x 8/10). The method for calculating the rate of a port working at another sub-rate is the same.

NOTE:
  • This parameter is configurable only when Synchronous is set to No.
  • This parameter is configurable only when Serial Port Rate (bps) is set to a sub-rate.
