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.

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.
