Exam 10: Signaling

The problem with in-band signaling is that it eats up precious bandwidth on shared trunks.

________ is the signaling network of the future.

ISDN ________ is the out-of-band signaling channel used to connect a digital switch to a PBX.

MTP and ISUP are only used when a database needs to be accessed, but TCAP and SCCP are used for normal call connection.

Why is CCS better than in-band signaling methods?

Loop start signaling and ground start signaling tell the switch that a telephone is ________-hook.

Signaling system seven (SS-7) and integrated services digital network (ISDN) are forms of carrier associated signaling.

Which of the following is a type of common channel signaling?

Loop start signaling is the type of signaling found on telephone lines that initiates dial tone when one lead is touched to the ground.

The goal of AIN is to define a network that is able to ________ a call at any point in the call process.

Signaling is responsible for:

The section of SS-7 protocol that establishes the connection through the network and uses the physical node address to rout the message to the appropriate destination is the:

Business systems such as a PBX or key system are adversely affected by incoming, outgoing call collisions and therefore require a special signaling method, called ________ start signaling, to eliminate the chance of glare.

The parts of the SS-7 protocol that normally go hand in hand are:

The advantage of ISDN ________ is that it provides two working channels and one 16 kbps data channel on one pair of copper wire with the two channels completely separate to allow no more than one telephone conversation to take place at the same time on the same wire pair.

Signaling system 7 (SS-7) replaced the ________ standard in the United States in the mid-1980's.

Local number portability (LNP) means that you can keep your old phone number even if you change providers.

An end-office, tandem, or toll switch of the typical SS-7 network architecture is referred to as the:

Which of the following is not part of the SS-7 message format used to carry information about the call being placed?

SSPs, STPs, and SCPs are connected to one another by ________ circuits.
