External stuff bits—Must be cleared on the CX29503 in DS3-M13/M23 and E3-G.751 modes.
When clear, stuff bits are inserted with the payload. This bit has no affect in DS3-C Bit Parity
mode.
External Frame Alignment bits—Must be cleared on the CX29503. When clear, the frame
alignment bits are automatically generated by the internal circuitry.
External P-Bit control—Must be cleared on the CX29503 in DS3-C Bit Parity and DS3-M13/
M23 modes. When clear, P-bits are automatically calculated by the internal circuitry. In E3-
G.751 mode, this bit has no effect.
External X/A/RDI-Bit control—Must be cleared on the CX29503 to disable insertion of X-bits
(in DS3), and A-bits (in E3-G.751) because this data is not provided on the TEXT input.
