11. Assume that a subscriber has shown a need for 100-wpm DC
teletypewriter service. The DCA circuit planner therefore specifies in the
Technical Service Order parameter code
a. N1.
b. N2.
c. N3.
d. D2.
12. Assume that the technical controller has available circuits carrying
parameter codes V1, S1, S2, V2, D1 and Z1. Which incoming circuits can be
patched over the outgoing circuit carrying D1 parameter code?
a. V1 and V2.
b. V2 and S1.
c. S1 and S2.
d. S2 and Z1.
13. Assume that the Telecommunication Service Order indicates the need for
the schedule Z4 parameter. This parameter indicates that the carrier system
should be conditioned for
a. 50-kilobit/baseband.
b. 20-kilobit/second data rate.
c. voice at a level of -17.5 dBm.
d. voice at a level of -21 dBm.
