1.1
• Single chip host based ISDN solution
• Integrates S-transceiver, D-channel, B-channel
• Replaces solutions based on ISAC-S TE PSB 2186
• Easy adjustment of software using ISAC-S and
• Various types of protocol support depending on
• Efficient transfer of data blocks from/to system
• Enlarged FIFO buffers (2x64 byte) per B-channel
• S-transceiver with TE, LT-S and LT-T modes
• D-channel FIFO buffers with 2x32byte
• D-channel access mechanism in all modes
• D-channel priority handler on IOM-2 for intelligent
