The DELAYMAX is a configuration parameter that specifies the maximum allowed delay for retransmission
(see clause 9.8).

It is used in the channel-initialization policy (CIpolicy) and in the online reconfiguration (OLR) procedures.
The downstream and upstream values of DELAYMAX shall be configured in the DPU-MIB.
The valid DELAYMAX values range from 1 to 16 ms in steps of 0.25 ms.

11.4.2.4 Minimum impulse noise protection against SHINE (INP_min_shine)
The control parameter INP_min_shine shall be set to the same value as the configuration parameter
INPMIN_SHINE.

The INPMIN_SHINE is a configuration parameter that specifies the minimum impulse noise protection
against SHINE (see clause 9.8).

It is used in the channel-initialization policy (CIpolicy) and in the online reconfiguration (OLR) procedures.
The downstream and upstream values of INPMIN_SHINE shall be configured in the DPU-MIB.
The valid INPMIN_SHINE values range from 0 to 520 symbol periods in steps of one symbol period.

11.4.2.5 SHINEratio

The control parameter SHINEratio shall be set to the same value as the configuration parameter
SHINERATIO.

The SHINERATIO is a configuration parameter that is used in the definition of the expected throughput rate
(ETR) (see clause 9.8).

It is used in the channel-initialization policy (CIpolicy) and in the online reconfiguration (OLR) procedures.
The downstream and upstream values shall be configured in the DPU-MIB.

The valid SHINERATIO values range from 0 to 0.1 in increments of 0.001.
NOTE – Typically, the detailed characteristics of the SHINE impulse noise environment are not known in advance by
the operator. Therefore, it is expected that this parameter will be set by the operator using empirical methods.

11.4.2.6 Minimum impulse noise protection against REIN (INP_min_rein)
The control parameter INP_min_rein shall be set to the same value as the configuration parameter
INPMIN_REIN.

The INPMIN_REIN is a configuration parameter that specifies the minimum impulse noise protection
against REIN (see clause 9.8).

It is used in the channel-initialization policy (CIpolicy) and in the online reconfiguration (OLR) procedures.
The downstream and upstream values of INPMIN_REIN shall be configured in the DPU-MIB.
The valid INPMIN_REIN values range from 0 to 63 symbol periods in steps of 1 symbol period.

11.4.2.7 REIN Inter-arrival time for retransmission (iat_rein_flag)

The control parameter iat_rein_flag shall be set to the same value as the configuration parameter
IAT_REIN.

The IAT_REIN is a configuration parameter that specifies the REIN inter-arrival time (see clause 9.8).
It is used in the channel-initialization policy (CIpolicy) and in the online reconfiguration (OLR) procedures.
The downstream and upstream values of IAT_REIN shall be configured in the DPU-MIB.

The valid IAT_REIN values are 0 (100 Hz), 1 (120 Hz), 2 (300 Hz) and 3 (360 Hz).
