Certain rules for bandwidth-on-demand apply, depending on 
whether BACP is negotiated. If BACP is not negotiated, the origina-
tor of the call will perform the dynamic bandwidth adjustments on 
its own. If BACP is negotiated, the decisions are made on either side 
but the call is always from the originator.

The Express 4110/4120 uses LZS

® 

technology from hi/fn

TM

 

(formerly 

known as STAC) for data compression.  The Ascend Communications 
version of this compression is also supported.  The Express 4110/4120 will 
automatically select the type of compression.  Compression is negotiated 
when this item is set to STAC (def).  No compression will be attempted 
when set to None.

Normally, this is not necessary over ISDN connections and can be set to 
Off

 (def) to disable it.
