Additional Features
A DSLAM may offer the ability to tag VLAN traffic as it passes from the subscribers to upstream routers. Though not a full stateful firewall, some DSLAMs also offer packet filtering facilities like dropping inter-port traffic and dropping certain protocols.
A DSLAM may also support quality of service (QoS) features like contention, differentiated services ("DiffServ") and priority queues.

Famous quotes containing the words additional and/or features:
“Dog. A kind of additional or subsidiary Deity designed to catch the overflow and surplus of the world’s worship.”
—Ambrose Bierce (1842–1914)
““It looks as if
Some pallid thing had squashed its features flat
And its eyes shut with overeagerness
To see what people found so interesting
In one another, and had gone to sleep
Of its own stupid lack of understanding,
Or broken its white neck of mushroom stuff
Short off, and died against the windowpane.””
—Robert Frost (1874–1963)
