22 Cross Connect (XC) Block Functional Description
The DS3/NSMI connectivity is established through a combination of DS3 specific MUXs controlled by registers
XC3_TPM_SRC
trolled by XC_PDATA[1—29]
(Table
tifunction system interface to the SPE mapper or M13.
Description of the DS3 connectivity will be presented in three sections: the test-pattern generator/monitor
(TPG/TPM), the DS3 basic connect, and the NSMI.
22.8.1 DS3 TPG/TPM Cross Connect
The DS3 test signals are routed through the XC3 crosspoint by programming register XC3_TPM_SRC as shown in
Figure
enable are provided from another block via the XC3 crosspoint. The TPG/TPM provide unframed test data that may
be connected to the SPE block for clear channel testing. For framed DS3 test data, the TPG/TPM are connected to
the NSMI interface in the M13 block and the M13 block DS3 interface provides the framed DS3 signal for test pur-
poses.
The DS3 TPG/TPM crosspoint’s connectivity is determined by a set of source3 identifiers (source3_IDs) for bits 5
and 6 of XC3_TSOURCE_ID in register XC3_TPM_SRC as defined in the following tables:
where XC3_TSOURCE_ID is defined as follows:
