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.
