Software-Based Data Compression

Software-based data compression works over WAN links running Frame Relay,

PPP, or X.25. It includes

• Compression for a FRE module at 4 x 128 KB/s compressed throughput, full

duplex; or 512 KB/s aggregate compressed throughput

• Compression on an Access Node (AN

) platform at 2 x 64 KB/s compressed

throughput, full duplex; or 128 KB/s aggregate compressed throughput

• Compression on all intelligent link interface modules (ILIs) that support serial

and ISDN BRI ports

• Support for all Bay Networks platforms: AN, ASN, and BN, plus VME

• Compression on MCT-1 and MCE-1 lines

Hardware-Based Data Compression

Hardware compression works over WAN links running Frame Relay and PPP.

Hardware compression is available as

• Optional daughterboards for Frame Relay and PPP networks that use the octal

synchronous link module for the BN, using FRE-2 processors only.

• Optional net modules for Frame Relay and PPP networks that use the ASN.

Hardware compression can compress data transmitted over WANs attached to

dual and quad synchronous, MCE1/ISDN PRI, MCT1/ISDN, dual sync with

ISDN BRI, and QBRI net modules.
