Data Sheet
channelized 8 MBit/s or unchannelized links for frame relay, router or DSLAM
applications with a maximum aggregate data rate of up to 90 Mbit/s per direction at 66
MHz PCI frequency
E1 frame boundaries are indicated by clock gaps
of 16 links, for HDLC, PPP or transparent mode (TMA) processing
each physical link. Supports DS0, fractional T1/E1 or T1/E1 channels
zero and 8.192 Mbit/s on all other ports
direction
supports configuration of subsystem ID / subsystem vendor ID via a serial EEPROM
interface
address and data bus in Intel mode or Motorola mode) which allows access to the
local bus via the PCI bus or which can communicate with a PCI host processor
through an on-chip mailbox
