9.4.1 Ethernet Cables
On the ATN 950B, Ethernet cables are used to input and output Ethernet service signals.
Ethernet cables are also referred to as network cables and can be classified into straight-through
cables and crossover cables according to the connection sequence of the copper cores in the
cables.
A network cable with a shield layer is a shielded cable and that without a shield layer is a non-
shielded cable.
The Ethernet service interfaces on the equipment are adaptive to the straight-through cables and
crossover cables. Hence, you can connect either type of the network cables to the Ethernet service
interfaces as required.
Ethernet cables need to be made on site.
