16.2 Software and Protocols
16.2.1 X.25 Features
 Selectable DCE or DTE at LAPB link layer 2 and X.25 packet layer 3
 1024 logical channels
 SVC and PVC (any mixture supported simultaneously)
 Packet sizes: 16-4096
 Window sizes: 1-7 (modulo 8), 1-127 (modulo-128/extended)
 Flow control facilities: packet & window sizes, throughput class
 Other facilities: reverse charge, etc
 DTE facilities: called and calling address extension
 Q-bit and M-bit control
 X.29 (PAD) support
16.2.2 X.25 / TCP Encapsulation and Conversion methods
 X.25 Over TCP (XOT) per RFC 1613 for X.25 transparency
 RFC1006 for ISO TP0 bridging
 Q-MBIT for X.25 More-bit and Q-bit preservation
 Cisco RBP
 Cisco RBP with Q-bit support
 RAW for byte-streaming
 MBIT for X.25 More-bit message preservation
 AEPN for X.25 More-bit and Q-bit preservation
 OFTP - ODETTE File Transfer Protocol (RFC 5024).
 LINE mode for legacy command line interfaces over X.25
 IAC-ESC for Telnet transparency
16.2.3 X.25 to TCP Connection Mapping and Address Translation
Incoming X.25 connections are scanned for a match from any or all of:
 X.25 interface (WAN port or XOT)
 called X.121 address
