acServiceTable
1.3.6.1.4.1.2785.2.8.1.1
This table is the common thread of all services, regardless of service
types, in other words, every service would have an entry in this table.
A service is identified by a tuple of {node, slot, port, channel}.
The {slot, port} pair identies the access port of a subscriber.
The port can support multiple services, and each such service is
identified by a 'service channel'.
To create a service, a row should be created in this table. When the
service type is set, a row is automatically 'created' in the
appropriate service type specific table. For example, to create an IAS
service, one first creates a row in this common table, and then set
acServiceType to IAS (which triggers the automatic creation of an
entry in the IAS service table), and then set the all necessary
parameters.
To remove a service, remove the row in this common table only.
