1. RFTC fetches R_CH_TO_QUEUE entry for DS0s 6 and 7 for line 2.
2. DS0 6 is being serviced by Queue MOD 32 = 10
Queue = line 2 x 32 + 10 = 74
DS0 7 is being serviced by Queue MOD 32 = 20
Queue = line 2 x 32 + 20 = 84
3. RFTC fetches the queue status and write pointer for queue 74. The queue is not in underrun.
4. RFTC fetches the queue status and write pointer for queue 84. The queue is in underrun.
5. RFTC fetches the active status for DS0 6 from R_ACT_TBL if DBCES is enabled
6. RFTC fetches the data for DS0 6 from the R_DATA_BUFFER.
7. RFTC fetches the data for DS0 7 from R_COND_DATA.
9.2.2.3.1 SRTS Support
Figure 55 shows the process implemented for each UDF line enabled for SRTS.
It queues the incoming SRTS values, and, when requested, passes this SRTS
value to the AAL1 Clock Generation Control block. This value, along with a
locally calculated SRTS value, is used by the AAL1 Clock Generation Control
block to determine the appropriate line frequency to synthesize.
The RFTC supports SRTS only for unstructured data formats on a per-line basis.
The SRTS_CDVT value in R_SRTS_CONFIG register must be configured
