22 Cross Connect (XC) Block Functional Description
22.8 DS3 Connectivity
The cross connect block also supports DS3 mapping to/from the SPE mapper and the M13 MUX, to dedicated
external pins (PIN). There is also an external NSMI I/O channel, which transfers DS3 data as well. In both cases
(standard and NSMI), the available sources are the M13 DeMUX or the SPE mapper, a set of external I/O pins, or
the test-pattern generator. The DS3 crosspoint’s connectivity is determined by an even smaller set of source3 iden-
tifiers.
Table 621. DS3 Connectivity
Note: DS3 external I/O is supported by dedicated pins. NSMI uses the multifunction system interface.
The symbols in
% = Primary (expected) modes of operation.
X = Unsupported mode.
& = represents loopback path.
NSMI = NSMI mode only.
T = Test mode.
