S/UNI®-IMA-32

Preliminary

32 Link Inverse Multiplexer for ATM (IMA) / UNI PHY

• Provides programmable limit on

allowable differential delay and

minimum number of links per group.

• Performs ICP and stuff-cell insertion

and removal.

• Supports IMA frame length (M) equal

to 32, 64, 128, or 256.

• Provides IMA layer statistic counts and

alarms for support of IMA Performance

and Failure Alarm Monitoring and MIB

support.

ATM OVER FRACTIONAL T1/E1

FEATURES

• Supports ATM over Fractional T1/E1

compliant with the ATM Forum

AF-PHY-0130.00 specification.

IMA

• Supports up to 32 T1, E1, G.SHDSL or

unchannelized links and up to 16 IMA

groups with 1 to 32 links/group.

• Link and Group State Machines

implemented on-chip requiring no real

time software in the data path.

• Fully compliant with the ATM Forum

Inverse Multiplexer for ATM (IMA)

1.1 specification and backward

compatible to IMA 1.0.

• Supports both independent transmit

clock (ITC) and common transmit clock

(CTC) modes.

• Supports all IMA Group Symmetry

modes: Symmetric/Asymmetric

configuration and operation.

LINE INTERFACE

•

32 T1, E1, G.SHDSL or unchannelized

links via 2-pin line interfaces.

UTOPIA / ANY-PHY INTERFACE

• Supports 8- and 16-bit UTOPIA L2 and

Any-PHY cell interfaces at clock rates

up to 52 MHz.

• Any-PHY transmit slave appears as a

32 port multi-PHY. The PHY-ID of

each cell is identified using in-band

addressing.

• Any-PHY receive slave appears as a

single device. The PHY-ID of each cell

is identified using in-band addressing.

• UTOPIA L2 transmit and receive slave

appears as a 31-port multi-PHY.

• UTOPIA L2 receive slave can also

appear as a single port with the logical

port provided as a prepend.

• Provides per link counters for statistics

and performance monitoring.

UNI

• Each link is software configurable as

either a UNI or part of an IMA group.

• Performs receive cell Header Error

Check (HEC) checking and transmit

cell HEC generation.

• Optionally supports receive cell

payload unscrambling and transmit cell

payload scrambling.

• Differential delay tolerance of 279 ms

(for T1 links) and 226 ms (for E1 links).

• Performs IMA differential delay

calculation and synchronization.

• Provides TC layer statistics counts and

alarms for MIB support.
