Maintaining an older alarm monitoring system is hard, and it just gets harder the older the system gets. Physical faults accumulate, equipment starts to break down, and repairing the monitoring system becomes a drain on department resources.
As your older monitoring system becomes less reliable, network visibility eventually declines, and you have an increased chance of not detecting and correcting serious network threats.
Eventually, your legacy system will break down completely, and you'll have to come up with a replacement option fast.
You can't meet the challenges of managing a 21st-century telecom network with a monitoring system that was designed in the 1980s. Slow serial connections, proprietary protocols, and primitive alarm management software cannot give you the best protection for your network reliability.
While your network alarm monitoring system has stayed the same, the environment that you work in has changed completely over the last ten years. You're under relentless pressure to raise network reliability to higher, near-perfect levels - while your budget for meeting staff and training costs have been cut to the bone.
Compared to the average network manager of the 1980s and early 1990s, you've got higher performance standards to meet, and you've got a smaller, less highly trained staff to do it with.
That's a tough job - and to meet this challenge, you need advanced telemetry features like after-hours monitoring, e-mail and pager alerts, automatic notification and correction, nuisance alarm filtering and qualification. You're not going to get what you need from your legacy system.
