RECEIVE SIGNALING Table 7
NOTES: (Applicable only to CAS systems)
1. RSD is valid for the least significant nibble in each indicated timeslot. Timeslot A data appears in bit
2. RSD does not output valid data during timeslots 0 and 16.
RECEIVE MULTIFRAME TIMING Figure 15
RECEIVE TIMING
The receive side output timing set is identical to that found on the transmit side. The user can tie receive
outputs directly to the transmit inputs for drop and insert applications. The received data of RPOS, RNEG
appear at RSER after six RCLK delays, without any change except for the HDB3-to-NRZ conversion
when HDB3 is enabled.
5, B in bit 6, C in bit 7 and D in bit 8.
