This read-create object holds one valid ATM address configured for the switch itself, as a row in a table that can hold more than one such address. Because a single switch can register more than one ATM NSAP address, for example a primary address plus a secondary alias used by another service, this object is the actual 20-byte address carried in one such row, and an incorrect value here means calls destined to that address simply won't route to this switch. An admin provisioning a second address for a switch that also answers as an ATM anycast server would create a new row and set this object to that distinct NSAP address alongside the switch's primary one.
