Synchronous When an AES router is in synchronous mode (i.e., it has a valid video reference signal), the router’s
level type is ‘Synchronous AES Mono’.
AES ‘takes’ in a “mono” partition are not paired. Each AES channel is independent. The 16×16
router has 32 independent inputs and 32 independent outputs. The 32×32 router has 64 independent
inputs and 64 independent outputs.
Subnet Mask A subnet is an identifiably separate part of an organization's network. A subnet allows a single large
network to be broken down into smaller ones. Typically, a subnet may represent all the machines at
one geographic location or on the same local area network (LAN). A subnet mask is the technique
used by the IP protocol to create a subnet address. Or, to put it another way, a subnet mask is a
screen of numbers used for routing traffic within a subnetwork.
