Customizing Hardware Compression

The following issues are specific to hardware compression:

• Selecting software or hardware compression (described on page 3-9

)

• Selecting a fallback compression mode (described on page 3-11

)

Selecting Software or Hardware Compression

When you configure a VC for compression, the default compression type varies

(Table 3-4

You can use software compression with a hardware compression daughterboard or

net module. Bay Networks recommends that you use hardware compression for

connections operating at speeds greater than 512 Kb/s. You should specify

software compression for VCs in excess of the number of contexts your hardware

compression daughterboard or net module can support.
