Two switching centres are connected by 20 trunks, with a busy-hour traffic of 0.5E per trunk. Use the data in Table 1 to find the probability that a trunk will be unavailable for a call, given that callers are unable to find a free line either:- i) ii) Hold on even though unconnected. Terminate the call immediately and do not try again. Table 1 k 10* k!
