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.
Data Services and performance monitoring
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
synchronous HDLC support
rate).
rate)
• Byte synchronous HDLC support for all channels (STS-1 and
higher rate)
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.
sub-rate DS3 channels.
• An Expansion mode allows multiple TIGRIS devices to share
expansion
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 with
Green/RoHS compliant option
• 1.2V core, 2.5V I/O
• 1.2V core, 2.5V I/O
• Estimated 3W power consumption
• 6.0W maximum power consumption
FTI-2 Lineinterface
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.
