ABSTRACT:
Multiple operating configurations in data circuit terminating equipment (DCE) are enabled through multiple queues stored in a random access memory and which are loaded with bits and characters coming either from data terminating equipment (DTE) or the telecommunications line. The DSP processor stores bits provided by a transmit circuit in a first queue, determines characters from the bits stored in the first queue based on a first transmission protocol and stores the characters in a second queue. A third queue is used by a control processor to store characters to be transmitted to a remote DCE. The DSP processor determines bits to be transmitted from the characters stored in a third queue based on a second transmission protocol, and stores those bits in a fourth queue. When the DCE is operating in a synchronous mode, the DSP processor determines PCM words for transmission based on the contents of the second queue and stores them in a fifth queue for transmission. Similarly, when the DCE switches to an asynchronous mode, the DSP processor determines PCM words based on the contents of the fourth queue and stores them in the fifth queue for transmission. A similar queue arrangement is provided for the receive circuitry of the DCE.
