12 28-Channel Framer Registers (continued)
The register in Table 406 provides a status indication of functional elements (FE) exchanged between the access
digital section and the exchange termination (ET), as defined in ETS 300 233, Section 9.3 and Table 2. These are
decoded from the A, Sa5, and Sa6 bits. The Sa6 code words are synchronized to the CRC-4 multiframe.
