SATURN USER NETWORK INTERFACE (622-MAX)

PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA INC., AND FOR ITS CUSTOMERS’ INTERNAL USE

TSOC3:

The Transmit SONET/SDH OC3 enable allows the S/UNI-622-MAX to

process transmit STS-3c/STM-1 data streams using the parallel line interface.

When TSOC3 is set high, the SONET/SDH transmit processors

TSOP/TLOP/TPOP are configured for STS-3c/STM-1 operation. When

TSOC3 is set low, the transmit side of the S/UNI-622-MAX is configured for

STS-12c/STM-1 operation. Setting TSOC3 high when LIFSEL is low is invalid

as the analog interface only operates at STS-12c/STM-4-4c line rates.

RX_LIFINV:

The Receive LIFSEL Inversion select (RX_LIFINV) controls the interpretation

of the LIFSEL pin for the receive side. When RX_LIFINV is set high, the

polarity of the LIFSEL input is inverted. When RX_LIFINV is set low, the

LIFSEL input operates normally for the receive side.

TX_LIFINV:

The Transmit LIFSEL Inversion select (TX_LIFINV) controls the interpretation

of the LIFSEL pin for the transmit side. When TX_LIFINV is set high, the

polarity of the LIFSEL input is inverted. When TX_LIFINV is set low, the

LIFSEL input operates normally for the transmit side.
