摘要
A bit oriented digital switch for controlled change of bit position and PCM word of chosen bits and bit groups in PCM words received by the switch. The switch is suitable to combine with a conventional word oriented switch to allow flexible switching of both entire PCM words and parts thereof. This switch also makes it possible to define a digital PCM transmission system, in which PCM words can contain one or several traffic channels and in which traffic channels that, occupy a bit group containing at least one bit, but not an entire PCM word, dynamically are allocated necessary space at an arbitrary available location in PCM words.
