Point-to-Point-Protocol (PPP)
Point-to-Point Protocol (PPP) is a full-duplex transmission protocol for communication between
two computers using a serial interface. A typical PPP connection is a personal computer connected
by telephone line to a server. For example, your Internet service provider (ISP) provides you with
a PPP connection so that the ISP server can respond to your requests, pass them on to the Internet,
and return your requested Internet responses to you.
Multi-link Point-to-Point Protocol (MLPPP)
MLPPP is used to connect multiple B-channels together when using PRI or BRI ISDN as the
WAN interface. This allows Business Communications Manager to connect B-channels
independently of each other so that the ISDN connection can be used for both voice and data.
WAN data compression
Business Communications Manager provides a WAN Data Compression feature. You can use data
compression on a permanent WAN connection and on a backup WAN connection. WAN Data
Compression is enabled by default. You can enable or disable WAN Data Compression from the
"Setting WAN Frame Relay Parameters"
depending on your system configuration.
On a permanent WAN connection, Business Communications Manager supports the following
data compression protocols:
•
Frame Relay Forum standard FRF.9 data compression protocol with STAC compression
algorithm
•
PPP Compression Control Protocol (RFC 1962) with STAC compression algorithm
On dial-up WAN connections, Business Communications Manager supports the following data
compression protocol:
•
Microsoft Point-to-Point Compression (MPPC), RFC 2118
