PTMC J13/J23 and J14/J24 Connectors
The following tables (
Table 5-6
and
Table 5-7
) outline how the TDM and Ethernet I/O signals
are supported on the CPC324 PTMC J13/J23 and J14/J24 connectors for each PTMC slot.
These signals are generally per the
PCI Telecom Mezzanine/Carrier Card Specification
,
PICMG 2.15 and its ECN. The major exception to the standard is that the CPC324 supports
type 2 mapping on J13/J23 and the type 5 mapping on J14/J24. The type 2 mapping was
chosen to support the existing RMII type interface between the PTMC and the baseboard. The
type 5 mapping was chosen on J14/J24 to allow for the newer 10/100/1G MDI pin assignments.
