Data MultiplexingLine Control Equipment - maximizes the use of
expensive communications facilities.
• Multiplexers - works in pairs, devices that combine several lower speed inputs from different sources into one high speed transmission mediums.

DYNANET Node Flexibility
Free mixing of:• Voice and data
interfaces• Copper and fibre
line terminals• In one and same
shelf
Service Changes:• Re-configure
existing interfaces• Add or change
new interface into any vacant slot
Increase aggregate capacity:
• Add more Copper line cards
• Replace copper with optical line
Benefits:• Easily configured and installed
products for simple use• Small number of different
items• Compatible mechanics• Easy and fast to service
