MediaGateway User Manual
Note: Please do not reset by pressing the reset button while the MediaGateway is in
bootloader mode! This may cause the problem of CHAPTER 9.1!

Please try another browser. Firefox and Chrome are recommended.
9.6 Delay Time for Ethernet packets through the
MediaGateway
The propagation delay of the switch depends on the load. The switch works collision-
free. It means that buffering is used to avoid collisions. The buffering causes delay
jitter sometimes. On high load jitter rises exponential.
On normal load the delay should be about 0.3 ms. But if the packet passes all 3
switches it may sum up to about 1 ms.
9.7 AVB Support
Currently Audio Video Bridging is not supported. Only automotive 802.1AS time
synchronization protocol is implemented (PTP).
9.8 Maximum Frame Size
The maximum frame size for all ports is 2000 bytes. Tagged and untagged frames will
be dropped if the frame length is larger than 2000 bytes.
