Thebranch office uses one T1 PRI Trunk card to connect to the Public Switched Telephone Network(PSTN). The branch office currently generates an estimated 420 Centium Call Seconds (CCS)during the busy hour to the PSTN. The company will be adding 10 new i2004 Internet Telephonesto the branch office, and it is estimated that after the addition of the 10 Internet Telephones thebranch office will generate an additional 135 CCS during the busy hour to the PSTN. The mainoffice is assigned zone 1 and the branch office is assigned zone 2. Each location uses theCODEC G.729AB with 30 ms packet duration for interzone communication. Using the informationgiven and exhibit provided, what is the best zone and PPI Trunk change that will support theadditional Internet Telephones at the branch office? (Assume a P.01 GOS.)A - There is sufficient PRI trunk capacity to support the additional traffic and create a zone 3 forthe 10 additional Internet Telephones.
