STB
A constant bit Rate (CBR) telephone system is considered to be circuit-
switching technology because the analog audio signal is? Ans✓✓✓
Converted into a digital DS0 circuit and switched to other cable
telephony customers or to the telephone company's network.
A modular plug contains four-, six-, or eight-pin positions. Each position
is numbered and is used to terminate a specific tip or ring wire from a
quad or twisted-pai cable. How are the pins on a modular jack
numbered? Ans✓✓✓ From left to right, with the locking tab down.

Generating a dial tone in either a traditional telephone call or
PacketCable VoIP call is similar, except? Ans✓✓✓ Equipment in the
central office (CO) for plain old telephone service (POTS) senses the
change in voltage and generates a dial tone where the embedded
multimedia terminal adapter (EMTA) senses the change and generates a
dial tone in PacketCable.
How does a DOCSIS modem receive its Internet Protocol (IP) address?
Ans✓✓✓ From a dynamic host configuration protocol (DHCP) server
that provides the CMTS with the modem's IP address, which is
forwarded to the modem during initialization.
