Transmission apparatus, transmission system, and transmission method
First Claim
1. A transmission apparatus coupled to an active transmission path and a standby transmission path, the transmission apparatus comprising:
- a memory; and
a processor coupled to the memory and configured to;
when the active transmission path is used for transmission,produce a first bit string by combining first bit data and second bit data,map the first bit string to a symbol corresponding to a data value of the first bit string according to a multi-level modulation system, andtransmit the first bit string to the active transmission path; and
when the a standby transmission path is used for transmission,duplicate first bit data,produce a second bit string by combining, in 2 bits, the first bit data and the duplicated first bit data,map the second bit string to a symbol corresponding to a data value of the second bit string according to the multi-level modulation system, andtransmit the second bit string to the standby transmission path.

Abstract
A transmission apparatus includes a memory and a processor coupled to the memory and configured to produce a bit string from a given number of bits of first bit data and second bit data, map the bit string to a symbol corresponding to a data value of the bit string according to a multi-level modulation system and transmit the bit string to a transmission path and acquire the first bit data and the second bit data from a first data signal and a second data signal, respectively, when the transmission path is an active transmission path and acquire the same first bit data and second bit data from the first data signal when the transmission path is a standby transmission path.

8. A transmission system comprising:
-
a first transmission apparatus and a second transmission apparatus coupled through an active transmission path and a standby transmission path, when the active transmission path is used for transmission, wherein the first transmission apparatus produces a first bit string by combining first bit data and second bit data, maps the first bit string to a symbol corresponding to a data value of the first bit string according to a multi-level modulation system, and transmits the first bit string to the active transmission path; and wherein the second transmission apparatus demodulates the first bit string, and separates the first bit data and the second bit data from the demodulated first bit string, and when the a standby transmission path is used for transmission, wherein the first transmission apparatus duplicates first bit data, produces a second bit string by combining, in 2 bits, the first bit data and the duplicated first bit data, maps the second bit string to a symbol corresponding to a data value of the second bit string according to the multi-level modulation system, and transmits the second bit string to the standby transmission path, and wherein the second transmission apparatus demodulates the second bit string, and separates the first bit data from the demodulated second bit string. - View Dependent Claims (9)
