- Which of the statement is false for the Out-Of-Band signalling? O It is having high speed data links (64 Kbps for national and 56 Kbps for international). O It is a software-based system that operates independent of the voice transport. O it is used in all modern telecommunications networks such as ISDN and GSM. O None of these.In a blocked-calls-delayed cellular system with 15 trunked channels, the load per user is 0.04 Erlangs and A= 0.25 calls/hour. Find the probability that a delayed call will have to wait for more than 5 s at a GOS of 2%. 90.1 % 88.5 % 94.1 % 94.9 % O OQ1. A call processor in exchange requires 240 ms to compute the call (call processing time). What is BHCA rating for the processor? If the exchange is capable of carrying 900E of traffic, what is the CCR? Also calculate the GoS of the system. Assume call holding time of 2 minutes. Explain different topologies of Data Communication Networks. Consider a group of 1200 subscribers which generate 800 calls during the busy hour. The average holding time is 3.4 minutes.
