Thy are both local cellular communication
This could be one of two types of signaling:Paracrine signaling is where a signaling molecule produced from one cell affects other types of adjacent cells.Autocrine signaling is where a signaling molecule produced from one cell affects itself and other adjacent cells of the same type.

SIGTRAN (for Signaling Transport) is the standard Telephony protocol used to transport Signaling System 7 (SS7) signals over the Internet. SS7 signals consist of special commands for handling a telephone call.
SS7 is the correct answer!
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.

Yes, Very important while working in Telecommunication networks.Your understanding in SS7 is mandatory to work in teleco.
