What is the difference between autocrine signaling and endocrine signaling?
In autocrine signaling, a substance produced by a cell effects that cell, as with cytokines in the immunity system. Endrocrine signaling is a systemic response to a substance.
Why are some circuit traces squiggly?
"Squiggly Traces" are actually know as Serpentine Traces. These wires are often used to make traces the same length. In high speed signaling, especially when using differential signaling ( http://en.wikipedia.org/wiki/Differential_signaling ). Differential signaling requires the signals arrive at the same time. Take a look at this Sparkfun Forum talking about what they are with a example picture: http://forum.sparkfun.com/viewtopic.php?f=20&t=29396
Advantages and disadvantages of time division multiplexing?
Advantages of TDMA 1. The user gets full bandwidth of the channel in a particuler time slot. 2. For bursty signals such as voice or speech TDMA gives maximum utilization of the channel 3. most suitable technique for digital transmission. Disadvantages of TDMA 1. it is not much suitable for continues signals 2. extra guard time are necessary 3. synchronization is necessary.
Which energy has no disadvantages?
There are no energy sources without disadvantages.
What are the advantages and disadvantages of electrostatic instruments?
What are the advantages and disadvantages manx iron instrument
Which PTSN connection usually uses common channel signaling and Signaling System 7 technology?
A connection between two exchanges connection
What is In- channel signaling?
In-channel signaling is also often referred to as in-band signaling. See http://en.wikipedia.org/wiki/Signalling_(telecommunications)#In-Band_versus_Out-Of-Band and http://en.wikipedia.org/wiki/In-band_signaling.The signaling used to establish and tear down a phone call was located in the same physical communication channel used to carry the call (i.e voice, fax or modem) traffic, and used DTMF tones. Examples are CCITT Signaling Systems 1-5 R1 & R2. Most books on SS7 should talk briefly about this.SS6 & SS7 moved to take the signaling out-of band, and to establish a common channel for all signaling in digital packet-based format (non-tone based) allowing one signaling channel to control a large number of "voice" circuits.
What type of signaling transmits call setup on the same channel as a voice signal?
In-Band Signaling (IBS)
What is the difference between in channel and common channel signaling?
One signaling path needed per trunk groupFaster and simpler to transfer information between control processorsNo possibility of interference with speech pathSignaling can't be accessed by customer.Value-added services of a signaling control pointShared processing for small officesAllows centralized decision making (flow mgmt)Permits Advanced Intelligent Network (AIN) services

What is signal?
In telephony, signaling is the exchange of information between involved points in the network that sets up, controls, and terminates each telephone call. In in-band signaling , the signaling is on the same channel as the telephone call. In out-of-band signaling , signaling is on separate channels dedicated for the purpose.
What is a common signaling molecule derived from a fatty acid?
eicosanoid
