The SDA includes lightning arrestors to protect the customer's local network from
lightning. The SDA is connected to a standard power outlet (110-240vAC). The
units are generally installed indoors in a communications cabinet or mounted on a
wall. An SDA can also be placed on a table or shelf next to the customer's
communications equipment.
Table 7-1 illustrates the data connector pinouts.
