Same way as their analog modem multilink. They were using this long
before the MLPPP became popular in ISDN. And yes they do use it on every
interface that makes sense. It is only later that they provided MLPPP
and MCPPP per RFC, as ISDN makes more use of it than the old proprietary
protocol, and its a multivendor standard.
