NOTES:
1. FPS – Framing Pattern Sequence.
2. FDL – 4 kHz Facility Data Link; M = message bits.
3. CRC – Cyclic Redundancy Check bits. The CRC code will be internally generated by the device
4. The user may program any individual channels clear, in which case bit 8 will be used for data, not
5. Depending on application, the user can support 2-state, 4-state or 16-state signaling by the appropriate
