Connect High-Speed Cabling
INTRODUCTION
This procedure provides step-by-step instructions to install the DS3 or STS-1 network cabling
to the backplane of the MX2820 shelf. Two standard BNC connectors provide the physical
interface to the network for each Multiplexer (MUX) module or each pair for 1:1 redundant
configuration. These BNC connectors provide the transmit and receive paths for the MX2820
system.
PREREQUISITE PROCEDURES
Obtain all necessary local instructions before proceeding with the MX2820 shelf installation.
The instructions for routing and connecting the high-speed cabling from the MX2820
backplane to the DS3/STS-1 network should be performed according to Central Office (CO)
Standing Operating Procedures (SOP).
The MX2820 shelf should be mounted in its permanent location in the CO before connecting
the cabling.
CAUTION
DSX-1, DS3, STS-1, and 10/Base-T Ethernet circuits from the
MX2820 are not to be connected directly to outside plant facilities.
