Gigabit Ethernet Nominal Buffer Level. Range of 50 to 475 milliseconds in increments of 5 ms. A change to this parameter will cause the Gigabit Ethernet processor to reset all of its internal Ethernet frame buffers. This will result in a momentary loss of data causing a minor glitch on all output streams. The buffer level is the normal standard starting level for an input stream buffer. It is highly recommended that this level not be changed from its default setting. The buffer level needs to be set at an appropriate amount to allow for network jitter, clock skew between the APEX and input source, and for maximum time between PCRs (100ms). In addition, the level must not be set too high as the buffer needs to be able to grow as packets are received and PCR processing is applied. This buffer level is the initial level the APEX will attempt to maintain at all times. Once written, the change to this parameter will take immediate effect. However, in order for the change to persist through subsequent reboots or power cycles, the change must be saved via the apexSaveConfig parameter. @Config(config=yes, reboot=no) @Save(apexSaveConfig, value=2) @File(config.ini, type='ini')
