Frame Relay Data Compression Protocol (DCP) as defined by FRF.9
PPP is a data link layer industry standard WAN protocol for transferring multi-protocol data traffic
over point-to-point connections. With this protocol, options such as security data compression, and
network protocols can be negotiated over the connection.

Frame Relay is a packet-switching data communications protocol that statistically multiplexes
many data conversations over a single transmission link. Data compression allows Frame Relay to
negotiate compression over Frame Relay permanent virtual channels (PVCs).

ISDN BRI is a switched Data Link layer control protocol which uses digital signaling to place a
call into an ISDN network. Once the call is made, PPP is then used to transfer data.

Firmware Data Compression
The STAC Electronics Stacker LZS Compression algorithm provides a minimum of 2:1 firmware
data compression for the CSX400 over PPP and Frame Relay. Firmware data compression is
supported in software on each WAN interface for line speeds of up to 256 Kbps. per WPIM, which
is equivalent to four DS0 channels. To use data compression, compatible equipment, (such as
another CSX400, or other vendors’ equipment which conforms to the applicable standards), must
be in use at both ends of the WAN link. This firmware method of data compression is used as the
default, if the hardware compression module is not installed.
