Line switching, also referred to as circuit switching, is how landline phone systems connect. This method uses a dedicated line to connect the calls. Call switching refers to the way calls are handled on a mobile network.
press the menu button on the call screen then select unhold
Circuit switching
A cellular telephone within a cell communicates to the call tower, which in turn is connected to the cellular telephone switching office (CTSO) by the telephone line. The telephone switching Office is then connected to the local telephone system. If the cellular telephone moves from one cell to another, the cellular telephone switching office then hands the connection from one cell to another.
How about using a media gateway device for inter-connecting a MPLS (Multi Protocol Label Switching) to any virtual PBX system.
A call delay is the amount of time between when a call arrives at a switching device and wehn no channel or facility is available to process the call.
yes
The voltage is measured by high and low range. Measurements are referred to as r.m.s. , switching impulses reflected by line to line, earth to line contact.
Some call a line of people a "queue" (pron. kyew). Others just call it a line.
By invoking a terminal emulator or switching to one of the virtual terminals.
billing customers, controlling their call switching equipment, etc.
through: wires, transformers, breakers, switches, etc.Something like:Power plant wires carry electricity to plant switching farm.Switches in switching farm direct electricity to step-up transformer for a transmission line.Step-up transformer increases voltage to reduce transmission losses.Wires from step-up transformer go to high voltage breaker to protect switching farm from transmission line current spikes.Transmission line wires attach to breakers and leave plant switching farm.Transmission line wires run hundreds of miles to consumer locations.Transmission line wires enter a distribution switching farm and attach to high voltage breakers to protect switching farm from transmission line current spikes.Wires from breakers go to step-down transformer to decrease voltage for safe distribution.Wires from step-down transformer go to switches in switching farm.Switches in switching farm connect electricity to desired distribution lines.Each distribution line has breakers on it to protect the switching farm and the line.Distribution lines run to various neighborhoods.At each customer location the distribution line connects to a step-down transformer to reduce the voltage to what the customer needs (e.g. U.S. residential 120V/240V 2phase).Wires connect the step-down transformer to the customer's fuse/breaker box and distribution panel.
No. They're "in-line" and you can't shorten that to "line." (Older folks still call them Rollerblades.)
