J4 : J4 is a 90-pin connector that routes computer telephony (CT) bus signals to the Compact-
PCI backplane. See Chapter for pinouts.
J5: J5 is a 110-pin connector that routes user input/output signals directly from the J24 connec-
tor at PTMC expansion site #2. It also routes optional RMII signals from both PTMC sites. See
Chapter for pinouts.
J6: J6 is a 3-pin header on the circuit board for the ejector switch (for factory use only).
J7: J7 is a 10-pin header on the circuit board that provides an in-system programmable (ISP)
JTAG interface to the programmable logic (PLD) devices (factory use only).
J11—J14: J11, J12, J13, and J14 are 64-pin connectors that support PTMC expansion site #1. See
Table 9-1 for pinouts.
J21—J24: J21, J22, J23, and J24 are 64-pin connectors that support PTMC expansion site #2. See
Table 9-2 for pinouts.
