T1 / E1 / J1 OCTAL FRAMER
IDT82V2108
PRELIMINARY
FEATURES
鈥?/div>
鈥?/div>
Octal Framer supporting T1, E1 and J1 Formats
Provides programmable system interface to support Mitel廬 ST-
bus, AT&T廬 CHI and MVIP bus, supporting data rates of 1.544 /
2.048 / 8.192Mb/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 con-
tains 128-byte deep FIFOs in both the receive and transmit direc-
tions
Provides jitter attenuation performance exceeding the requirements
set by the associated standards for both Rx and Tx path
Provides payload, line and digital loop-backs
Provides a floating Pseudo Random Bit Sequence / repetitive pat-
tern generator/detector, which can be assigned to any one of eight
framers, the pattern may be inserted / detected in 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 counter CRC error, framing bit er-
ror, far end block CRC error (E1), out of frame event (T1/J1) and
change of frame alignment event (T1/J1)
Provides programmable In-band Loop-back Code transmitter/re-
ceiver, Bit Oriented Message generator / detector
Supports polled or interrupt driven processing for all events
Supports multiplexed or non-multiplexed address/data bus MPU in-
terface for configuration, control and status monitoring
JTAG boundary scan meets IEEE 1149.1
Low power 3.3V CMOS technology with 5V tolerant inputs
Operating industrial temperature range: -40
