Table 12-15 – FTU-R CLR message SPar(2) bit definitions

ITU-T G.994.1 SPar(2) bit Definition of SPar(2) bit

Number of SOC symbol Always set to ZERO.
repetitions (RS)
Number of DS Always set to ZERO.
initialization data
symbols (sds)
Downstream RMC offset Always set to ZERO
CD time out If set to ZERO, indicates that the FTU-R supports only the default CD_time_out_1 value
of ten seconds and the CD_time_out_2 value of twenty seconds. If set to ONE, indicates
that the FTU-R supports valid CD_time_out_1 values and valid CD_time_out_2 values in
addition to the default value, as indicated in the corresponding CD time out 1 and CD
time out 2 NPar(3) fields.

ITU-T G.994.1 SPar(2) bit Definition of NPar(3) bits
Profiles Each valid profile is represented by one bit in a field of six bits. The valid profiles are:
106a, 106b and 212a. Each profile supported by the FTU-R is indicated by setting its
corresponding bit to ONE (Note).
Duration of Channel This 8-bit field indicates the minimum duration of the Channel Discovery 1-1 stage
Discovery 1-1 expressed in multiple of 8 192 symbol periods with cyclic extension requested by the
FTU-R. The valid values are from 1 to 16. The FTU-O shall round up the time to the
nearest superframe.
CE length multiplier Each bit of this 9-bit field represents a CE length multiplier m, excluding the default
value 10 (see clause 10.4.4). For each CE length multiplier that the FTU-R supports, the
corresponding bit shall be set to ONE.
Number of symbol Each bit of this 6-bit field represents an MF value other than 36; specifically bit 1 shall
periods in TDD frame be set to ONE indicating the FTU-R supports the MF value 23. Other bits in this 6-bit
field are reserved by ITU-T and shall be set to ZERO.

CD time out 1 This 3-bit field shall be coded as an unsigned integer n=7, indicating that the maximum
CD_time_out_1 value supported by the FTU-R equals forty seconds.
CD time out 2 This 3-bit field shall be coded as an unsigned integer n=7, indicating that the maximum
CD_time_out_2 value supported by the FTU-R equals eighty seconds.
NOTE – A list of the profiles supported by the FTU-R is available in the DPU-MIB as FTUR_PROFILES inventory information.
