Applications
IEC-Q TE
Version 5.2
1.1
• ISDN U-transceiver with IOM-2 and optional micro-
• Compatible to NT modes and TE mode of
• Perfectly suited for terminal and TA applications
• U-interface (2B1Q) conform to ANSI T1.601, ETSI
• IOM-2 interface for connection of e.g. ISAC-S,
• Pin compatible to version 4.4 in the P-LCC-44
In µP mode:
• Parallel or serial microprocessor interface and watchdog
• µP access to B-channels, D-channel and intercommunication channels
• µP access to IOM-2 Monitor-channels and C/I-channels
• Adjustable microcontroller clock source between 0.96MHz and 7.68MHz
• Selection between Bit clock (BCL) and Data clock (DCL)
