Does Livingston support Ascends proprietary Bandwidth on Demand

If your customers are using Ascends MP+ protocol, which is basically
RFC1717 multilink protocol with some none standard enhancements,
it is entirely possible that your Ascend customers will work just fine.

Livingston supports two functions that provide variable bandwidth on
demand. Livingston's own proprietary Multi line load balancing, which
is limited to async modem connections and RFC171 standard Multilink PPP.
