Calculate the TRIB and effective utilization.

TRIB Exercise:

K = # information bits per character

M = frame length in characters

R = data transmission rate in characters per second

C = overhead characters (non-information characters) per frame

P = probability a frame will require retransmission

T = time between frames in seconds

[Given:

256 Kbps Circuit

K=8 (8 bit ASCII)

M=1500 characters per frame

R=32000 characters per second

C=656 overhead bits

P=.02 (1 frame in every 100)

T =.015 (25 milliseconds)
