10. c--para 2-3f
The TLP level is -3 dbm. This level is therefore 0 dbm0. The 6-db pad
determines that the signal entering the equipment will be at a relative level
of 6 db below 0 dbm0, or -6 dbm0.

12. a--fig. 2-1
13. b-table I
A gain of 6 db is equivalent to a power ratio of approximately 4 times
(3.981).
14. c--para 2-5c
Noise level of -50 db is 40 db above -90 db (0 dbrn), so it can be given
as +40 dbrn.
15. c--para 2-5, example 2
Noise level of -50 dbm is 53 db below the TLP of +3 dbm.
Noise level with
respect to the TLP is therefore -53 dbm0.
16. d--para 2-6c
17. b--para 2-6c
The nominal loss for an LD trunk is 3 db. The receive level is therefore
3 db less than the send level of -3 dbm, or a level of -6 dbm.
18. d-para 2-1c(4)
19. a--para 2-6d(1)
-3 dbm + 6 db = +3 dbm.
