付属資料１６空線信号について

16.1 空線信号

本規格においては空線信号は通信用チャネル信号（TCH1）（音声）として、一括通報終了後に送信す

る。

16.2 空線信号の信号定義

空線信号の TCH フィールドのビットパターンを参考として定義する。次の事由により無音となるミュー

ト信号を推奨する。 (1) 一括通報中はTCHをそのまま音声CODEC処理部へ渡して（メモリコピー等）いるので、一括通報

終了時に送信する内容は、制御信号ではなく音声信号の方が望ましい。

(2)一括通報終了後には、送信する音声信号は、

①定められたミュートパターンをTCHに入れる

②音声入力を切った無音信号をTCHに入れる

のいずれかと想定され、確実に無音となる①が望ましい。

(3) 空線信号を制御信号にした場合、受信機が空線信号を受けてからスピーカを閉じるまでの間、音声

CODEC処理部へ制御信号が出力されてしまう問題がある。

(4) 空線信号を制御信号にした場合、仮に強制切断指示信号を受け損ねた場合は、数秒間にわたり音声

CODEC処理部へ制御信号が出力されてしまう問題がある。

16.3 空線信号のビットパターン

次を推奨する。（この後スクランブル処理をかける）なお、このデータ列の音声CODEC処理部への取り

込みは、MSBファーストとする。すなわち以下に示すビット列で FFFF FFFF FFFF FFFFの後は、 01010100 10001110 00010100 10011010 ………

（5 4 8 E 1 4 9 A ………）と入力する。
