(From lecture note #1, slide title "Strict Real
-
Time")


2)

Object

oriented (OO)
techniques are increasingly being used to specify and
develop telecommunications software.

Answer:
TRUE

(From reading paper, title "Communications Software

3)

Most companies in U.S are in level 4 of SEI CMM

Answer:
FALSE

(From lecture note #2, slide title "SEI CMM")


4)

FAST is relatively inexpensive because no new technology is required, it
leverages the expertise of domain expertise, and can provide real benefits
--
code generation, software maintainability, and reuse
--
in a r

of time. As a result, software can be produced quicker and at a lower cost.

Answer:
TRUE

(From lecture note #2, slide title "Conclusion" of FAST)

I

1) TCP/IP (Transmission Control Protocol / Internet Protocol) is the common
name
for a family of over 100 data communications protocols used to organize
computers and data communications equipment into computer networks.


Answer:
TRUE


2) In LANs, transmissions over a shared media which can be received by any
station attached to the ne
twork.

Answer:
TRUE


3) In satellites, signals transmitted or retransmitted by orbital device, and intended
for direct reception by the public.

Answer:
TRUE


4) Call management: The process by which calls (usually incoming) are directed
to follow certain s
teps based on predetermined scenarios. Call management
allows calls to be routed to particular agents (or groups of agents) based on
"triggers" such as:

a)

the number called

b)

the time of day

c)

the geographic origin of call

d)

all of above

Answer: (
d
)


5) In ATM, th

a packet, into which information is segmented for transmission using ATM. The
cell has a:

a)

5
-
byte header and contains 48 bytes of payload

b)

4
-
byte header and contains 49 bytes of payload
