Refer to the inset of the control port in the figure "Faceplate of a 32-port E1
TDM with PEC NTHW92" (page 210). Both ends of the cable have the same
pinout, and the control port pinout is the same for all DS3 and E3 cards.

Assigning sparing panel connections for 32-port E1 TDM FPs

The 32-port E1 TDM function processor uses a sparing panel to support
one-for-one sparing and multiport aggregate devices for customer equipment
connections. The figure "Cable connections between two 32-port E1 TDM
FPs and a 3-port sparing panel NTFP99" (page 214) 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, in this case
from a multiport aggregate device.
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 Main.
