FEATURES
! Highlights
– Provides API command set for convenient configuration and
operation. An embedded controller and a downloaded software
are used to interpret the commands. Functions can be
added by software upgrading.
– Supports IMA group auto detect.
– Supports link backup so that a backup link can be automatically
added when a previously configured link fails.
– All the state machines are implemented in hardware.
– Advanced cell buffer management algorithm to support ATM
QoS requirements.
! Other Features
– Accommodates up to 4 IMA logical groups.
– Supports 4 T1/E1 channelized or unchannelized links.
– Supports T1 ISDN links.
– Supports MIXED mode: links not assigned to an IMA group
can be used in UNI mode.
– Supports symmetrical and asymmetrical operation.
– Supports Common Transmit Clock (CTC) and Independent
Transmit Clock (ITC) timing modes.
– Provides 4 Utopia Level 2 8 bit cell level handshake MPHY
interface to ATM device.
– Supports maximum link delay tolerance of up to 212 ms for E1
or 281 ms for T1 (when 512 KB external memory is used).
– Provides parameters for MIB (Management Information
Base).
– Supports dynamic addition/deletion of links to/from a working
IMA group.
– Supports non-multiplexed Intel or Motorola microprocessor
interface.
– Loopback capability at both TDM and Utopia ports.
– Supports MVIP.
– JTAG boundary scan meets IEEE 1149.1.
