We have drawn the statistical holding patterns of both types of. We spared some circuits for data traffic and the same number ofcircuits for voice traffic to finally have an idea how much loss an operatorcompany, dealing with voice telephony bears while operating with datasubscribers using traditional techniques of primary rate (PRI) or basic rateintegrated services digital networks (BRI). We have studied this impactkeeping in view the concerns of revenue, clientage, economy, marketing,installation cost and all other aspects.Telecommunication industry in Pakistan, monopolized by PTCL iscurrently adopting traditional techniques to facilitate the data serviceprovider companies. We have proved through mathematical calculations thatwhen PTCL furnish one PRI (2Mb/s) connection to their data subscriber andsuppose that they have sacrificed thirty (30) number of voice subscribers,they actually sacrifice more than ninety (90) number of voice subscribers.We have described in detail all the demerits of the existing techniques beingadopted by telecommunication industry in Pakistan to off-load the datatraffic.
