I need help in finding out if the setting of an ISDN port on an office connect 531 router to stac (extended) means that stac compression is improved and greater rate of transfer occurs between routers with the same capability, or does it mean that the port is configured to check packets for errors (i.e CRC) more rigorously than with stac default compression?

This is an obsolete product and is the equivalent of a 761 cisco ISDN router. Documentation has been hard to come by from 3Com's website.

To summarise, does extended stac improve speed or is it for greater levels of error checking at ncp point of ppp (DLL of layer 2 OSI)?

Help would be much appreciated, I have to find this information out in order to propose a solution to a cleverdick network manager who keeps throwing such details at me.
