SATURN USER NETWORK INTERFACE (622-MAX)

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

DLE:

The Diagnostic Loopback, DLE bit enables the S/UNI-622-MAX diagnostic

loopback where the S/UNI-622-MAX’s Transmit ATM (TXCP) are directly

connected to the Receive ATM (RXCP). When DLE is logic one, loopback is

enabled. Under this operating condition, the S/UNI-622-MAX does not

operate normally in the transmit direction or receive direction. When DLE is

logic zero, the S/UNI-622-MAX operates normally.

TFPEN:

The Transmit Frame Pulse Enable (TFPEN) enables the TFPI input. When

TFPEN is set low, the TFPI input is disabled. When TFPEN is set high, the

TFPI input is enabled.

SDH_J0/Z0

The SDH_J0/Z0 bit selects whether to insert SONET or SDH format J0/Z0

section overhead bytes into the transmit stream. When SDH_J0/Z0 is set

high, SDH format J0/Z0 bytes are selected for insertion. For this case, all the

J0/Z0 bytes are forced to the value programmed in the S/UNI-622-MAX

Transmit J0/Z0 register. When SDH_J0/Z0 is set low, SONET format J0/Z0

bytes are selected for insertion. For this case, the J0/Z0 bytes of a STS-N

signal are numbered incrementally from 1 to N.

When SDH_J0/Z0 is set high, the transmit section trace buffer enable bit,

TSTBEN can be used to overwrite the first J0/Z0 byte of a STS-N signal.
