Cabling Summary

Introduction

This appendix provides details on the cabling required to install the MGX 8220 shelf.

Note In all cable references, the transmit direction is from the MGX 8220 shelf, receive is to the MGX 8220 shelf.

T3 Trunk Cabling

Trunk cables connect the T3 port on the BNM backcard to the BNI T3 port on the colocated BPX node. See Table A-1and Table A-2for details.
