ATM Subscriber Access Multiplexer
A telephone central office multiplexer that supports SDL ports over a wide range of network interfaces. An
ASAM sends and receives subscriber data (often Internet services) over existing copper telephone lines,
concentrating all traffic onto a single high-speed trunk for transport to the Internet or the enterprise intranet.
This device is similar to a DSLAM (different manufacturers use different terms for similar devices). (Cisco
Systems Inc.)
Autonomous System Boundary Router
ABR located between an OSPF autonomous system and a non-OSPF network. ASBRs run both OSPF and
another routing protocol, such as RIP. ASBRs must reside in a non-stub OSPF area. See also ABR, non-stub
area, and OSPF. (Cisco Systems Inc.)
Auto-negotiation
A feature that allows twisted-pair ports to advertise their capabilities for speed, duplex and flow control.
When connected to a port that also supports auto-negotiation, the link can automatically configure itself to
the optimum setup.
Auto Uplink
Auto Uplink technology (also called MDI/MDIX) eliminates the need to worry about crossover vs.
TM
straight-through Ethernet cables. Auto Uplink will accommodate either type of cable to make the right
TM
connection.
AVL tree
Binary tree having the property that for any node in the tree, the difference in height between the left and
right subtrees of that node is no more than 1.
