CEPT Time Slot 16 Multiframe Structure
The T7230A supports three CEPT signaling modes: channel associated signaling (CAS) or per-channel signaling
(PSC0 and PSC1); common channel signaling (CCS); and international remote switching module (ISM) signaling.
Channel Associated Signaling
The channel associated signaling (CAS) mode utilizes time slot 16 of the FAS and NOT FAS frames. The CAS for-
mat is a multiframe consisting of 16 frames where frame 0 of the multiframe contains the multiframe alignment pat-
tern of four zeros in bits 1 through 4. Table 20 illustrates the CAS multiframe structure of time slot 16. The T7230A
can be programmed to force the transmitted line CAS multiframe alignment pattern to be transmitted in the FAS
frame by selecting the PCS0 option or in the NOT FAS frame by selecting the PCS1 option. Alignment of the trans-
mitted line CAS multiframe to the CRC-4 multiframe is arbitrary. The receive line CAS alignment is defined by the
received data.
Table 20. ITU CEPT Time Slot 16 Channel Associated Signaling Multiframe Structure
Notes:
Frame 0 bits 1—4 define the time slot 16 multiframe alignment.
X0—X2 = time slot 16 spare bits.
Ym = time slot 16 remote multiframe alarm (RMA) bit (1 = alarm condition).
