Signaling Support
The above signals may be used to support different signaling applications for CCS, CAS-CC, or
CAS-BR. For each method, different ways of access to signaling data are implemented:
Access via
a. an intelligent controller without the need of supporting signals (e.g. SAB 82525, HSCX)
b. a controller supported by the ACFA
c. a DMA controller
d. the board microprocessor
a. Access via an Intelligent Controller
Applications: CCS, (CAS-CC)
The intelligent controller is able to locate the signaling data on the system internal highway by itself
when supplied with the synchronous pulse SYPQ of the system (see figure 9). In PCM 24
applications, the normally unused input XSIG has to be connected to XDI.

PCM 24: Additional Function Receive
If enabled via bit ACR.DLC, this signal provides a 4-kHz DL clock which
marks the DL-bit position within the data stream at RDO.
PCM 24: Additional Function Transmit
If bit ACR.EXMF is reset, its function is equivalent to AFR for the transmit
direction.
If bit ACR.EXMF is set, this input signal can be used to synchronize the
transmitter of the ACFA externally for multiframe begin.
