FEATURES S a at .D w w w E1Fx8 Device 8-Channel E1 Framer TXC-03109 DATA SHEET PRELIMINARY DESCRIPTION The E1Fx8 is an eight-channel E1 (2048 kbit/s) framer designed with extended features for voice and data munications applications. AMI and HDB3 line codes are supported with full alarm detection and generation per ITU-T G.703, G.775 and I.431. Integral receive dual unipolar rail dejitter buffers (ITU-T G.735-739 and G.823) are provided. The transmit and receive sections of each of the eight framers are independent, including framing, with individual slip buffers to allow operation in a wide range of switching and transmission products. Framing algorithm support for ITU-T G.704, G.706 and ETS 300 011 is included. Access and control for signaling and data are provided via a Motorola/Intel-patible microprocessor interface. For HDLC link applications, each framer supplies a full duplex HDLC controller with dual 128-byte FIFOs (for Sa4-Sa8 access) in addition to onboard latching of all performance parameters, requiring minimal software overhead. Word-wide National bit read/write access is provided, with full Sa6 code support. Diagnostic, test, and maintenance functions are integrated, including E1 and per time slot local and remote loopback modes, per channel PRBS/code word generator/analyzer and...
