The N525 ETSU permits Ethernet traffic to be used over fiber optic cable to extend its distance and enhance its security. It creates a demarcation point between the Service Provider offering enhanced Ethernet services and the Enterprise CPE location receiving it. The ability to offer enhanced Ethernet services is gaining a great deal of popularity with Service Providers, however no Ethernet specific demarcation point existed until now. The N525 is a very cost effective Integrated Access Device for Ethernet, Fast Ethernet and Gigabit Ethernet deployed at the customer premise or local Telco Central Office providing a managed demarcation point between the Service Provider’s network and the End User’s network. The N525 ETSU offers a variety of popular user interfaces for increased flexibility. The interfaces are field replaceable and hot swappable for ease of use providing a low MTTR. Available user interfaces include auto sensing and software configurable Tri-Speed 10/100/1000Base-Tx, 10 Mbps, 100 Mbps and Gigabit optical, CWDM ready and Single Fiber BIDI interfaces.  The N525 ETSU provides powerful local and remote management features to help eliminate costly field visits.  In-band SNMP and SideBand management make the far end equipment appear local and provide end-to-end management, monitoring and control. Local management can also be accomplished through the provided Craft Port or 10BaseT Ethernet port. SNMPv1, SNMPv2c, SNMPv3, RMON, Telnet, PPP and SLIP are standard. The CanogaView Smart Element Manager provides an even higher level of control and can integrate under umbrella management systems like HP OpenView.  The N525’s standards based design and IEEE compliance allows interoperability with other IEEE compliant devices.  The N525 was also designed to be used with the Canoga Perkins L351, L357, L312, L322 and L332 Media Converters.
