FEATURES

? Octal Framer supporting T1, E1 and J1 formats

? Provides programmable system interface to support Zarlink Semiconductor

Inc. ST-BUS?, AT&T? CHI and MVIP bus, supporting

data rates of 1.544, 2.048 & 8.192 Mb/s; up to four links can be

byte-interleaved on one system bus without external logic

? Provides up to three internal floating HDLC controllers for each

framer to support ISDN PRI and V5.X interface. Each HDLC contains

128-byte deep FIFOs in both receive and transmit directions

? Provides jitter attenuation performance exceeding the requirements

set by the associated standards for both Rx and Tx path

? Provides payload, line and digital loopbacks

? Provides a floating Pseudo Random Bit Sequence / repetitive pattern

generator/detector, which can be assigned to any one of eight

framers, the pattern may be inserted / detected on an unframed or

Nx64K or Nx56K (T1 only) basis

? Provides signaling insertion / extraction for CCS / CAS and RBS

signaling system

? Provides programmable codes insertion, data / sign inversion and

digital milliwatt code insertion on a per channel / timeslot basis

? Supports automatic / manual alarming transmit and integration

? Provides performance monitor to count CRC error, framing bit error,

far end block CRC error (E1), out of frame event (T1/J1) and

change of frame alignment event (T1/J1)

? Provides programmable Inband Loopback Code transmitter/

receiver, Bit Oriented Message generator/detector

? Supports polled or interrupt driven processing for all events

? Supports multiplexed or non-multiplexed address/data bus MPU

interface for configuration, control and status monitoring

? JTAG boundary scan meets IEEE 1149.1
