Discovering Problems Network Anomalies can occur anytime, anyplace for a wide variety of reasons 3:09pm 20% Packet loss due to duplex mismatch 2:36pm Over-utilized WAN link causes packet loss We all know that packet loss, latency, and jitter can cause poor call quality. <SPACE> Finding the exact source and cause of these can be difficult without the right instrumentation. Network issues can be caused in a variety of locations by a variety of reasons. Understanding and diagnosing problems requires visibility to the entire network. Knowing what to look for can be tricky, as networks are dynamic and change over time. What is required is a tool that can point out the problems no matter where or when they occur. 4:26pm Broadcast storm caused by mis-configured network printer 11:15am Performance degradation due to under-powered router

Covering the Network Problem: Network Anomalies Cause VoIP Quality Issues Solution: PathSolutions VoIP Performance Manager All Switches and Routers are queried for information Install PathSolutions VoIP Manager Getting continuous visibility into the entire network is the optimal solution. Here’s how PathSolutions’s VoIP Monitor works: SwitchMonitor installs on one computer in the network. <SPACE> It communicates with all of your network devices via SNMP <SPACE> to gain visibility into all links in the network. With this configuration, every single link is monitored without having to deploy agents across the network, or configure span ports. In addition, specific errors (like duplex mis-matches or cable faults) can be detected on any link to pinpoint the exact source of packet loss. Result: One location is able to monitor all links in the entire network for performance and errors.

VoIP Performance Manager Total VoIP Visibility™: Broad: All ports on all routers & switches Deep: 18 different error counters collected and analyzed Network Prescription engine provides plain-English descriptions of errors: “This interface has a duplex mismatch, and this is the full-duplex side of that duplex mismatch” It acts like an extra Senior-level network engineer on your staff: Discovering and helping to resolve network issues before they become business problems. 3

When Where Why Easily learn about problems that occur 3:16pm 28% Loss from Duplex mismatch 10:12am 12% Loss from Alignment Errors Getting continuous visibility into the entire network is the optimal solution. Here’s how PathSolutions VoIP Performance Manager works: VoIP Manager installs on one computer in the network. <SPACE> It communicates with all of your network devices via SNMP <SPACE> to gain visibility into all links in the network. With this configuration, every single link is monitored without having to deploy agents across the network, or configure span ports. In addition, specific errors (like duplex mis-matches or cable faults) can be detected on any link to pinpoint the exact source of packet loss. 2:34pm 11% Loss from Collisions 8:42am 7% Loss from cabling fault

Benefits Detect issues before they become problems. Resolve VoIP and network problems faster. Proactive network optimization minimizes business impacts – lost revenue and productivity. Network staff focuses on improving the network versus configuring tools. What is one-level up on MTTR? Must align with business bottom line on slide 3: Lost revenue Lost productivity Unhappy employees Ability to detect issues before they happen and fix them. Enables you to have optimal network. Proactive--Business losses are minimized because networks sings. When not optimal, you know and can fix before they become problems. People are freed up to tune VoIP Manager gives you the big picture of your network’s performance. Not just a single point to a single point. <SPACE> Its design permits continuous monitoring to be performed, <SPACE> and generate alerts if network conditions degrade to a point where call quality would be affected. VoIP Manager will monitor switches, routers, servers, network printers, and any other device that supports SNMP. Thus, VoIP Manager provides a complete solution to finding and resolving network issues. Most companies find and resolve more problems on their network within the first week of deployment than have been resolved in the previous year. 5
