Description: gInpMaxDelay - The maximum downstream delay in ms. This is the upper limit for the delay that is added to the transmission delay only caused by retransmissions. Here the receiver and/or the transmitter shall identify and discard all DTUs whose payload cannot be transferred over the reference point at the receiver without violating the delay_max limit. The time stamp shall be the criterion for discarding the DTUs. The processing delay between the U-interface and the retransmission sub-layer of the receiver in the retransmission data path direction shall be excluded from consideration for delay_max in the retransmission data path direction. The valid values are all integers from 1 to 63. ITU-T G.998.4 7.1.1 Control parameters, 7.1.2 Valid configurations, and 8.1.6 Time Stamp.
