What else can I help you with?
For digital lines which device is used to establish the communications link between the customer equipment and the local loop?
For digital lines the device that is used to establish the communications link between the customer equipment and the local loop is CSU/DSU. The call setup time of a circuit switched WAN implementation considered a drawback is data cannot be transferred until a circuit has been established.
What is the purpose of a squuelch circuit?
A squelch circuit is installed in a radio communications receiver to shut down the output when no speech is being received, in order to suppress interference noises. All airborne VHF/UHF communications receivers have them.
What network technologies does not use circuit switching?
Packet Switching - Computer Communications (Digital)Circuit Switching was used for old fashioned telephony. At present, many companies use VOIP (Packet Switching) for voice communications.
In voice communications circuit switching is preffered over packet switching Give reasons?
You need a dedicated circuit for carrying voice communications that cannot be shared with others. That won't happen with packet switching, which will result in choppy and non-understandable conversations.
What is the difference between mlln and data circuit?
a mlln circuit is a data circuit
What is open circuit and short circuit?
Consider two points (A and B) in an electric circuit. An open circuit between A and B means there is no electrical connection between A and B. A short circuit between A and B means there is an electrical connection between A and B.
What is the difference between series and parralal circuit?
difference between series is one pathway through circuit,difference between parralal is more then one pathway through circuit.
The difference between short to a voltage circuit and short to a ground circuit?
A short circuit is an abnormal connection between two nodes intended to be at different voltages. A voltage circuit is caused intentionally for the purpose of voltage sensing. A ground circuit occurs between a phase and the ground.
What is the Relationship between resistance and inductance in a RL circuit?
What is the Relationship between resistance and inductance in a RL circuit?
Does XO Communications Outsource to India?
The answer is YES... They outsource their order entry, ASR, LSR and circuit tester departments.. All to INDIA!
What is difference between magnetic circuit and electric circuit?
magnetic circit has a magnet and electri circuit has electricity
What is the relationship between the voltage applied to a circuit and the velocity of electrons within that circuit?
The relationship between the voltage applied to a circuit and the velocity of electrons within that circuit is direct. When a higher voltage is applied to a circuit, the electrons within the circuit move faster, resulting in an increase in their velocity.
