Choose the following Business which will involve CS2K Switch for its Operation?
A
Correct answer
Explanation
IBLc (Integrated Business Line - commercial) involves the CS2K Switch for its operation. CS2K is likely a specific switch platform (possibly Call Server 2000 or similar). The other options - DTV (Digital TV), RHPs (likely Residential Hosted PBX), and RHPc (Residential Hosted PBX commercial) - do not involve the CS2K switch in their operation. This tests specific knowledge of which business line uses which switching infrastructure.
