Using an Amphenol Connector
If the RC-2 Pro lnterface is not appropriate for your application, you can
replace it by running a 25-pair cable with a female Amphenol connector
from the interface connector on the Digital Feedback Eliminator to a
66B-type punchdown block in standard color code order. Table 2-2 lists
the pin assignments for the Interface connector.
