2. Define the Fallowing:
CPS: is the “brain”. It has access to all functional groups from the NCP to the line and trunk modules.
NCP: Is connected to the CPS and line and trunk modules. It receives questions from the line and trunk units regarding call routing, feature request, and so forth.
ICS: Sits between the switching fabric and the line or trunk modules and is used to connect the two
Trunk module: is a term used to designate the trunk side of the switch
Line module: is a term that is used to designate the line interface side of the switch
3. Explain the difference between a tandem switch and a class 5 switch. A tandem switch is a class 4 switch, its main purpose is to switch trunks, between the toll switch and the local telephone net work , and between the CLEC regional center class 5 switches, between the ILEC’s end-office class 5 switches, and between operator services toll switches called OSPS’s.
A class 5 switch (local) has line modules, trunk modules, interface communications modules, a switch fabric, network switch processors and central switch processors. It is also referred to as an end-office switch because, as it sounds, it sits in the central office.
4. Explain the difference between a tandem switch and a long distance switch. A tandem switch is a class 4 switch, its main purpose is to switch trunks, between the toll switch and the local telephone net work , and between the CLEC regional center class 5 switches, between the ILEC’s end-office class 5 switches, and between operator services toll switches called OSPS’s.
A long distance switch routes traffic through the long distance network. The types of interfaces that terminate on a long distance switch are intermachine trunks (ITMT’s); they can also connect to databases that are used to validate calling card calls.
5. Explain the difference between a long distance switch and an international switch. A
