Bit No.
Type
These bits are valid when the FDIS bit (b0, E1-062H,...) is 0. They control what kind of frame is generated:
= 0: Enable the generation of the Basic frame, CRC Multi-Frame and Channel Associated Signaling (CAS) Multi-Frame.
= 1: Disable the generation of the Basic frame, CRC Multi-Frame and Channel Associated Signaling (CAS) Multi-Frame.
When the Basic frame is generated and the SiDIS bit (b5, E1-062H,...) is ‘0’, it contains the value to replace the International bit (Bit 1) of the
