Device Interworking
Performs byte stuffing for transparency processing.
Performs frame check sequence generation using the CRC-16.ISO-3309 and CRC-32
polynomials.
Aborts packets under the direction of the host or when the FIFO underflows.
Provides a SATURN POS-PHY Level 3 compliant 32-bit wide datapath (clocked up to 104
MHz) with parity support to an internal 2Kbyte FIFO buffer (256 bytes per channel).
Allows the two channels to be switched (crossbar) and/or bridged channels on the transmit
direction at the SONET/SDH path level.
With one S/UNI-8x155 device, supports up to four 1+1 APS interface or a single 1:4 APS
interface. Supports channel aliasing at the path level.
With two S/UNI-8x155 devices, supports up to eight 1+1 APS interfaces or a various 1:N
APS interfaces up to a single 1:8 APS interface.
Allows the eight channels to be switched (crossbar) on the receive direction at the
SONET/SDH path level.
Provides two transmit differential PECL bit-serial interfaces at 622.08 Mbit/s to switched
receive channels (crossbar) or source transmit channels (bridge) with a second S/UNI-
8x155 device at the SONET/SDH path level.
Provides two receive differential PECL bit-serial interface at 622.08 Mbit/s to switch
receive channels (crossbar) or source transmit channels (bridge) with a second S/UNI-
8x155 device at the SONET/SDH path level.
Provides performance monitoring of bit errors across the two receive streams.
