Note: 1.Only frame positions (within the 20-frame multiframe) that carry S- or Q-channel
On the IOM-2000 interface, the S/T multiframe information is included in the DX/DR data
stream (transparent to the VIP). The values of the multiframe are controlled by the DSP
software in the DELIC.
When multiframe synchronization is not achieved or lost, the VIP mirrors the received F
bits. Once the multiframe synchronization is established, the DSP sends the multiframe
synchronization command to the VIP (MSYNC bit). Upon reception of the MSYNC, the
VIP stops mirroring the F
