Understanding User Networks in Telecommunications
The user network is the set of elements that allows the electrical connection between the user equipment with the central office, so that each user has a circuit for exclusive use.
Conditions for User Networks
A user network must comply with certain conditions:
- Sufficient: Meeting the needs of high demands of new users.
- Elastic: Being able to adapt to phone development in successive periods.
- Flexible: It suits the actual development.
- Economic: Able to offset the interest on invested capital.
- With Quality
Hydractive Suspension: Technology and Operation
Hydractive Suspension
Hydractive Suspension is an enhanced version of hydropneumatic suspension; it is a type of computer-controlled suspension.
Proceedings of the Suspension
Variation of elastic elements is achieved by having a third sphere that can be connected or disconnected from the other two. The connection or disconnection of the additional sphere to the other two for each axis is controlled by the stiffness regulator, one per axle.
- Soft Setting: The weight is distributed across all three spheres.
