False, an OC3

24
Q

Sonet is more used in the USA, SDH in Europe

A

True

25
Q

CES is typically used to transmit voice and video over MPLS

A

False, CES is transported over ATM networks

26
Q

TDMoIP is a transport technology optimized for carrying E1/T1, E3/T3 trunks and multi-line serial data over packet-switched networks (PSNs)

A

True

27
Q

IPoDWDM is a technology that integrates Routers into DWDM

A

False, the opposite. In practice, it transfers the transponder function to a router card, so there is no need for optical to electrical to optical conversion in a DWDM system transponder.
In summary: The Router operates as a transponder
