Which service uses telephone control messages and signals between the transfer points along the ..

Answer / guest

Answer:: A

Signaling System 7 (SS7) uses telephone control messages and
signals

between the transfer points along the way to the called
destination.

Time-division Multiplexing (TDM) has information from
multiple sources

and allocates bandwidth on a single media. Circuit switching
uses

signaling to determine the call route, which is a dedicated
path between

the sender and the receiver. Basic telephone service and
Integrated

Services Digital Network (ISDN) use TDM circuits. X.25 and
Frame Relay

services have information contained in packets or frames to
share

non-dedicated bandwidth. X.25 avoids delays for call setup.
Frame Relay

uses permanent virtual circuits (PVCs).

2 Answers   HCL,






here is your question sahin Hi Jitendera, If i m not wrong, then in EIGRP, Metric weight is set to K1(Bandwidth)=1, K2(Delay)=0, K3(Reliability)=1, K4(Load)=0, K5(MTU)=0. This is default setting for EIGRP. I knew about it from ICND 2 cisco press book. Three more questions - a) If we change the K value (I mean metric weight)on a router what will happen??? b) When redistribution is necessary in EIGRP. Is there any condition for that??? c) What is reference bandwidth for metric calculation in EIGRP. As we know, in OSPF, on a CISCO router reference bandwidth is 10Mbps.
