Make-Before-Break (MBB) Video Switching
When configuring your SNP, if bandwidth is exceeded, switches will become Make After Break. In order
to maintain Make-Before-Break switching, observe the following configuration limits:
Signal
Limit for Make-Before-Break Switching
1.5G
No restriction for 32 channels
3G
7 of 8 channels per processor
3G (2022-6)
6 of 8 channels per processor
UHD
Up to 7 of 8 channels per SNP
For best results, use a balanced configuration where each processor has one section configured for input
and the other section configured for output.
When configured in this way, it is possible to have a 16 x 16 matrix of 3G with MBB (4 x 4 channels of
UHD with Make-Before-Break, or 4 IP Rx and 4 IP Tx per processor).
