PPP
TWICEŽ PPP
(Point to Point Protocol) complements PacketWare's comprehensive
line of portable communication software products to provide access
to PPP networks.
TWICEŽ PPP customers receive an unprecedented
PPP network inter-operability guarantee. Our clients benefit from
their investment in the PacketWare technology because they know they
can rely on us for a complete range of protocol software including
X-25,
Frame Relay,
and
TCP-IP.
TWICEŽ PPP is
based on 17 years experience developing performance communication
software to the open Streams architecture with the quality
guaranteed by PacketWare's rigorous development methodology, audited
and compliant with both government and laboratory
standards.
Features and Benefits

platforms which do not support a native Streams environment
- Full compatibility with USL's
published DLPI interface
- Full support for all relevant Internet
standards
- Includes IP Network Configuration
Protocol (NCP) as well as TCP/IP header compression module
- Open architecture for easy support of
other upper network Layers
- Full dynamic run-time configuration
per interface
