Best-in-class design status that “no more than 75% of your bandwidth should be use voice traffic”, so as not to share data traffic. A compressed voice call talk 31.2 kpbs bandwidth. Foe and E1 line o bandwidth 2.048 mbps. What is the maximum no of simultaneous calls that can be carried if there is to be no blocking.

a) If a grade of service of 1% is expected. How much traffic (in erlangs) can be carried over this link?


b) How much traffic (in erlangs) can and E1-PRI link carry at 1% QOS?


c) If you are given the option of selecting between the legacy PBX with E1-PRI connectivity and the IP-PBX connectivity.
Which one should you choose given reasons.

Note : E1q-PRI is more expensive than E1 digital trunk.
