5. ePort Network Ethernet Connectivity within Primary’s Metro Fiber Optic Network OpticalAccess OpticalGigabitEthernetNetwork ManagedSwitch/Router GB MAN Switch/Router Switch/Router GB WAN Router Internet ePort is Reliable. Primary Network works with multiple Tier 1 ISP peering partners. This means that eport customers will have access to the Internet, even if one of the Tier 1 providers experiences a major outage. Also, because eport traffic does not traverse on a voice-oriented infrastructure, we don't have to put your data through multiple conversions between IP and telephony protocols. That means efficient, native-data transmission, and fewer points of conversion to jeopardize reliability. Plus, we've ensured reliability through diversity and redundancy with monitoring and fault detection that proactively averts potential outages or overloads. And, we give you access to live, technical support 24 hours a day, seven days a week.
