Overview
This appendix provides the interface connections, pin
assignments, and other information for the following:
• Digital or leased-line network connection
• NIMs
• SDU
• 50-pin modular plug
• Carrier backplane connectors
• D-Lead control interface
Pin assignments vary from one product to another. For
information on a specific cable or connector, see the
appropriate installation or user’s manual for the product.
Digital/Lease Network
Connections
Two 50-pin connectors on the backplane provide an
interface between the carrier and the digital/lease
network.
• Figure A-1 is a diagram of the 50-pin digital or
analog leased-line network interface connector.
• Table A-1 provides the digital or analog leased-line
network interface connector pin assignments.
