Transmit Path Processing
The SARC-48 Transmit Path processes path defects detected by the egress pointer interpreter
SHPI. A consequent action is a transmitted path AIS insertion (TPAISINS) which is forwarded
to the egress SVCA_R block. The first step to the generation of the consequent action
indications is to monitor the TALLPAISC, TPAIS, TPAISC, TPLOP, and TPLOPC signals
generated by the egress path pointer interpreter and to generate TPAISPTR and TPLOPTR
defects. With the TPAISPTR and TPLOPTR defects and the external TPAIS information, the
Transmit Path can prepare the transmit path AIS insertion (TPAISINS). The
TPAISPTRCFG[1:0] bit is the register configuration bit that defines the TPAISPTR defect. Only
one TPAISPTRCFG[1:0] bit exists for 48 transmit paths. A transmit path alarm indication
signal defect is declared when the selected Equation 6 is true. A transmit path alarm indication
signal defect is removed when the selected Equation 6 is false. No interrupt is generated with
this defect.
Equation 6:
TPAISPTRCFG[1:0]
“00”
“01”
“10”
Others
The TPLOPTRCFG[1:0] bit is the register configuration bit that defines the
TPLOPTR_NOEND defect. Only one TPLOPPTRCFG[1:0] bit exists for 48 transmit paths.
The TPLOPTR defect can be optionally terminated by a TPAISPTR defect.
The TPLOPTREND bit is the register configuration bit that defines if TPLOPTR is terminated
by TPAISPTR or not. Only one TPLOPTREND bit exists for 48 transmit paths. When the
TPLOPTR is terminated by TPAISPTR and this TPAISPTR is true the TPLOPTR is forced to
false, in any others case it takes TPLOPTR_NOEND value. A transmit path loss of pointer
defect is declared when the selected Equation 8 is true. A transmit path loss of pointer defect is
removed when the selected Equation 8 is false. No interrupt is generated with this defect.
