CAS bits are transferred as-is.
T1 ESF T1 SF Only A and B bits transferred.
T1 SF T1 ESF A and B bits transferred. C and D bits sourced from the
SF_to_ESF_low_CAS_bits field in Port[n]_cfg_reg.
For structured-with-CAS bundles connecting two T1 SF/ESF interfaces, the per-bundle Tx_dest_framing
bit in the
Bundle Configuration Tables indi
cates the destination interface framing type (SF or ESF).
The figures below shows the location of the CAS bits in the TDMn_RSIG_RTS data stream for each framing mode.
