T1 / E1 / J1 OCTAL FRAMER
IDT82V2108
PRELIMINARY
FEATURES
• Octal Framer supporting T1, E1 and J1 Formats
• Provides programmable system interface to support Mitel® ST-
bus, AT&T® 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°C to +85°C
• Package available: 128 pin PQFP
144 pin PBGA
APPLICATIONS
• High density internet E1 or T1 / J1 interface for routers, multiplex-
ers, switches and digital modems.
• Frame relay switches and access devices (FRADS)
• SONET / SDH add drop multiplexers
• Digital private branch exchanges (PBX)
• Channel service units (CSU) and data service units (DSU)
• Channel banks and multiplexers
• Digital access and cross-connect systems (DACS)
