Important! Because the individual tributaries of a VCG can take
different paths through the SONET network, they may experience
different delays through the network. VCGs use differential delay
buffers to accommodate for differential delay.
Follow local procedures to reengineer the circuit path of the affected
tributary through the SONET network to reduce differential delay.
