The 650-S provides a centralized test system which remotely tests circuits accessed from a digital cross-connect system (DCS) or other network element. From your network control center, you can use the CENTEST 650-S to test services and facilities throughout your network. The system helps lower maintenance costs by reducing dispatches and using personnel more efficiently. It also improves responsiveness to customers by enabling more efficient network troubleshooting and maintenance, resulting in faster closure of trouble tickets and turn-up of new circuits.
