The method according to claim 1, further comprising: at a repeater, receiving a signal from said first termination station; terminating said non-selected overhead portion of the received signal to produce an intermediate signal; inserting first overhead information to said selected overhead portion of said intermediate signal to produce a transmission signal; and transmitting the transmission signal to said second termination station. 5. The method according to claim 1, further comprising: at a repeater, receiving a signal from said first termination station; terminating said non-selected overhead portion of a received signal to produce a first intermediate signal, performing error-correction decoding of the first intermediate signal; terminating said selected overhead portion of the first intermediate signal to produce a second intermediate signal; inserting first overhead information to a selected overhead portion of said second intermediate signal to produce a third intermediate signal; performing error-correction encoding of the third intermediate signal, inserting second overhead information to said non-selected overhead portion of an encoded third intermediate signal to produce a transmission signal; and transmitting the transmission signal to said second termination station. 6. The method according to claim 1, wherein said frame structure is divided into said selected overhead portion and said non-selected overhead portion depending on a type of each overhead portion. 7. The method according to claim 6, wherein said frame structure is divided into said selected overhead portion and said non-selected overhead portion depending on whether the overhead portion includes information required for network management. 8. A transmission method for transmitting a signal from a first termination station to a second termination station through at least one repeater, said signal having a frame structure having a plurality of subframes, each of which subframes includes an overhead, a payload, and an error-correction code, said method comprising of: determining whether said overhead is a selected overhead for error correction, depending on a type of said overhead; when said overhead is a selected overhead for error correction, performing an error-correction process using information which includes said overhead; when said overhead is not a selected overhead for error correction, performing said error-correction process using information from which said overhead is removed; and transmitting the signal from said first termination station to said second termination station through said at least one repeater. 9. A system for transferring a signal from a first termination station to a second termination station through a plurality of repeaters, said signal having a frame structure having a plurality of subframes each said subframe comprised of an overhead portion, a payload portion, and an error-correction code portion, said system comprising: a first termination station; a second termination station; and at least one repeater, said first termination station comprising: a first selected-overhead inserting section for inserting first overhead information to said selected overhead portion of said frame to produce a first intermediate signal; an encoder for performing error-correction encoding of the first intermediate signal; a first non-selected-overhead inserting section for inserting second overhead information to said non-selected overhead portion of an encoded first intermediate signal to produce a first transmission signal; and a first transmitter for transmitting said first transmission signal to
