Refer to the inset of the control port in the figure "Faceplate of a 2-port
DS3Ch TDM FP with PEC NTHW91" (page 161). The PS is the power
supply. Both ends of the cable have the same pinout, and the control port
pinout is the same for all DS3 and E3 cards.
For more information, see "Cables and cable management" (page 315).
The figure "Cable connections between 2-port DS3C TDM FPs and a 3-port
sparing panel NTFP99" (page 165) shows the connection endpoints between
the spared FPs and their sparing panel. It also identifies the endpoints at the
sparing panel from the far-end or next-hop CPE.
A sparing panel has a transmit (Tx) and receive (Rx) pair for each port. When
cabling Passport FPs and sparing panels, do Tx-to-Tx and Rx-to-Rx for all
equipment from the FP up to the far-end termination of the FP connection.
The sparing panel NTFP99 can also be deployed as a one-for-one fanout
panel (or patch panel) provided the connections are to the Main Tx and Rx
ports.
