A eficiência do enlace de comunicação é reforçada adaptando-se dinamicamente às exigências de largura de faixa de enlace superior e enlace inferior dos canais de comunicação. Os módulos de tempo são flexível e dinamicamente alocados para transmissões de enlace superior (Ta) ou de enlace inferior (Tb, Tc, Td), dependendo das necessidades de largura de faixa de um canal. Exigências de largura de faixa de enlace de comunicação são continuamente monitoradas usando conjuntos de parâmetros de exigência de largura de faixa predeterminados. Canais de comunicação configurados para ter larguras de faixa simétricas ou assimétricas de enlace superior/enlace inferior, dependendo das necessidades do canal.
