ISDN U HDLC Interface 1-Line 160Kbps 5V 44-Pin LCC

Version 5.3 of the PEB 2091 (IEC-Q), is an optimized version of the IEC-Q, which features all functions needed for building basic rate digital subscriber line systems. It complies to all international and all important national standards (e.g. ITU, ANSI, ETSI, CNET, BT). The IEC-Q holds the Bellcore approval for "Layer 1 ISDN Basic Access Digital Subscriber Line Transceivers", including all objectives, and it is the de facto industrial standard for these applications.

• ISDN U transceiver with IOM®-2 and microprocessor interface control
• Pin and functionally compatible to all previous PEB 2091 versions
• Perfectly suited to all LT, NT, TE, DAML, Repeater, NT-PBX and Wireless Local Loop applications.
• U-interface (2B1Q) conforms to all relevant international standardization norms (e.g. ITU, ANSI, ETSI) and all important national norms (e.g. CNET, BT), including all optional transmission requirements with sufficient margin
• Application optimized DSP with adaptive echo cancellation and equalization, automatic polarity adaption, clock recovery, automatic gain control and build-in wake-up function.
• IOM®-2 interface for connection of e.g. EPIC®, ELIC®, IDEC®, SBC-X, ICC, SICOFI®-2/4, SICOFI®-2/4TE, ISAC®-S, ARCOFI®, ITAC®, HSCX-TE, ISAR, IPAC, 3PAC
• Automatic maintenance control features
• Multipurpose controller interface in stand-alone mode
• Single 5 Volt power supply
• Low power CMOS technology with power down mode
• Available in three packages: P-LCC-44, M-QFP-64 and T-QFP-64
• Available in the extended temperature range
• Parallel or serial microprocessor interface
• Wake up function in NT mode without IOM®-2
• Undervoltage detection circuit
• Watchdog
• µP access to all data and control channels of the IOM®-2 interface
• Adjustable microcontroller clock source between 0.96MHz and 7.68MHz
• Selection between Bit clock (BCL) and Data clock (DCL)
• Supports synchronization of base stations in Wireless Local Loop applications
• Supports D-channel arbitration with ELIC® linecard (e.g. PBX)
