Development Tools and Support
The LAPB module features are as follows:
The X.25 module features are as follows:
B-4
• Supports external loopback between two channels or on the same channel
• Trace option for reporting to system management each primitive issued by the LAPD
• Implements 1988 CClTT Recommendation X25, chapters 2.1 through 2.4
• Supports up to twelve distinct physical channels with each operating as an independent
• Modulo 8 or modulo 128 operation
• Applicable for DTE and DCE applications
• Uses dedicated transmit pool for fast control frame generation
• Dynamic modification of protocol parameters
• Independent of layer 1 and layer 3 implementation
• Message-oriented interface
• Independent configuration of upper and lower layer modules interfacing with each
• Special mode for internal loopback (frames are not sent to the driver)
• Supports external loopback between two MC68302 serial channels or on the same
• Trace option for reporting to system management each primitive issued by the LAPB
• Fully implements 1988 CCITT Recommendation X.25, chapters 3.1 through 7.3
• May be used with both layer 2 modules: LAPD or LAPB
• Unlimited number of layer 2 entities (interfaces)
• Supports up to 4095 logical channels for each interface
• Many DTE/DCE interface parameters (configurable for each interface):
• Layer 4 message fragmentation/assembly using M-BIT
• Q-BIT support
• All standard CCITT X.25 facilities
• Compatible with X.213 interface primitives
• Link parameters (configurable separately for each interface):
