Ajax Auto Components manufactures automobile parts for the service and retail markets. The Ajax corporate campus i located north of Atlanta, Georgia. Ajax is presently using an Avaya PBXforits campus phone system that uses DCS signaling. The PBX cannot support all the new features that Ajax requires, so the company has decided to change its system from traditional TDM to IP telephony. The campus currently has 942 employees in three two -story office buildings, a single Aiotestking.com
story R&D facility, and a manufacturing building. The five buildings are all connected via an FDDI ring. The campus is divided by County Line Road, which is the actual division between Fulton and Cobb counties. The office buildings are located on the east side of County Line Road, in Fulton County; the RSD building and manufacture plant are located on the west side County Line Road in Cobb County.
It will be your job to help the company migrate from the traditional PBX system to a Cisco Unified Communications Manager system on a converged voice and data network.
Due to business considerations, Ajax has chosen to do a phased implementation. While the migration is taking place, the existing PBX needs to coexist with the new Cisco Unified Communications Manager. Which three statements are to regarding a phased migration? (Choose three.)
A.
You must consider maintaining the integrity of call pick-up groups, hunt groups, and shared lines.
B.
There are no number-plan overlap considerations between the PBX and the Cisco Unified Communications solution.
C.
A phased migration provides a parallel system that allows the users to revert to the PBX if something unexpected occurs.
D.
The level of feature transparency between the existing PBX and the Cisco Unified Communications Manager is
determined by the signaling protocol used.
E.
The phased cut-over allows for the verification of the IP telephony database configuration before the system
carries live PSTN traffic.
F.
The additional time added to the project plan to deploy using the phased approach is offset by the user’s ability
explore and learn the new system priortothe cut-over.
