22 Cross Connect (XC) Block Functional Description
22.8.3 NSMI Cross Connect
The Super Mapper cross connect supports interconnection of the network serial multiplexed interface (NSMI) to the
SPE mapper, M13 MUX/deMUX, or the NSMI system interface of the framer block as shown in
cross connects are controlled by programming the XC_PDATA[29]
bytes in registers XC_PIND_SRC15 and XC_PINS_SRC15. As previously discussed, the TPG/TPM can
send/receive data using the NSMI interface of the M13. Only the framer block can disassemble the NSMI payload
into DS0 channels and signaling. Connectivity to the M13 and SPE mapper is for transport in a proprietary format
only.
The NSMI crosspoint’s connectivity to the multifunction interface external I/O is determined by a set of XC1 source
identifiers (SOURCE_IDs). The NSMI connectivity is defined as a special with the source ID = 000 for
XC_PDATA[29] and XC_SYNC[29] bytes in registers XC_PIND_SRC15 and XC_PINS_SRC15, with a
CHANNEL_ID restricted to 5, 24, 25, or 26 (see
The channel ID is defined as:
