TIGRIS

OC-48 Multi Protocol Termination for 2047 Channels

Part Number S4811, Rev. 2.4 July 2006

Data services and performance monitoring

• Store and forward architecture with extensive buffering using

external DDR SDRAM.

• 2047 bi-directional ATM/HDLC channels that can be

assigned to tributaries from STS-12 to DS0.

• Bit Synchronous HDLC support all channels (DS3 and lower

rate)

• Byte synchronous HDLC support for all channels (STS-1 and

higher rate)

• Direct Map ATM support.

• G.832 E3 ATM support.

• Support for up to 48 DS3 PLCP ATM mapped channels.

• Support for up to 48 Sub-Rate DS3 channels.

FTI-2 line interface

• Four independent STS-12 capable interfaces selectable from

four serial 622 MHz LVDS Flexible Tributary interfaces (FTI-

2) or one Parallel FTI 8-bit x 78MHz Interface. Parallel

Interface is compatible with standard Telecom Bus interfaces.

• An Expansion mode allows multiple TIGRIS devices to share

a single FTI interface (allows up to 8K channels).

• Glueless interface to up to four AMCC Evros framers.

System Interface

• SPI-3 32bit @ 104MHz for cells/packets and error status.

• The SPI-3 supports four interleaved channels (four logical

PHY ports).

• Pre-pended packet tag for channel ID, length, error status,

TX queue priority, and TX per packet loopback.

Device Specifications

• 899 PBGA (31x31mm with 1mm ball pitch) package

• 1.2V core, 2.5V I/O

• Estimated 3W power consumption

TIGRIS is a high density data-termination device supporting 2047 channels operating at an aggregate rate of 2.488Gbps. The

device aggregates and terminates both ATM cells and HDLC frames, enabling ATM services such as Cell Relay, IMA, AAL2/5, and

frame based services, such as PPP, Frame Relay, and Multi-link PPP and Multi-link Frame Relay. The 2047 individually assignable

channels can be configured for Frame Relay, HDLC, PPP, and or ATM services for DS0, NxDS0, DS1/E1, DS3/E3, STS-1c, STS-3c

and STS-12c rates.

TIGRIS supports up to 48 channels of subrate DS3 services interoperating with major CSU/DSU vendors protocols and can be com-

bined with AMCC’s nP3700 to provide AAL2/5, IMA, and Multilink services for all 2047 channels.
