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