Which statement is true about only out-of-band signaling?
A.
A signaling bit is robbed from each frame.
B.
Signaling bits are sent in a special order in a dedicated signaling frame.
C.
All signaling is directly associated with its corresponding voice frame.
D.
All voice packets carry their own signaling.
Explanation:
Out-of-Band signaling is telecommunication signaling exchange of information in order to control a telephone call. Out-of-Band signaling uses common channel signaling (CCS), that means signaling information is transmitted using a separate, dedicated signaling channel.Answers A C D are characteristics of Channel associated signaling (CAS) so they are not correct.
