Ethernet Private Line Service-Wide Area Network (EPLS-WAN)

Ethernet Private Line Service-Wide Area Network (EPLS-WAN) is a point-to-point, fixed full-bandwidth Ethernet service that provides inter-city data transport over combined-access (local) and long-haul (core) networks. EPLS-WAN provides a range of speed options depending on the transport.

When we provide EPLS-WAN via 1 Gbps, or 10GigE Premium speeds, once your packets are on the AT&T long-haul network, they travel over an optical transport network (OTN). This helps assure you of low latency and a fast recovery from failure–typically within 400 milliseconds.

When we provide EPLS-WAN via Ethernet over Fiber (at 10 Gbps or 100 Gbps) the transport network is our long-haul core optical wavelength network, which uses Dense Wavelength Division Multiplexing (DWDM). In this case, EPLS-WAN operates as an unprotected, point-to-point service via an 802.3 Ethernet signal and provides route diversity and packet collision avoidance; however, recovery from failure requires manual intervention.

Continuous Network Monitoring and Performance Management

  • Dependable network management expertise and reliable support from a single point of contact.
  • Continuous (24×7) monitoring and troubleshooting, to help ensure that your network always performs at its optimum level.

Redundant Electronic Components

  • To help prevent failure and ensure the continuous operation of our transport equipment, we use many redundant components, such as power supplies.
  • Redundancy options are available, such as dual entrance facilities.
  • Redundancy measures help minimize the risk of outages and increase your system’s reliability.
