The T1/E1 copper to fiber network interface device (NID) provides a solution for those users that need to extend T1/E1 connections over fiber. The T1/E1 supports Small Form Pluggable (SFP) transceivers to support a variety of fiber types, distances and wavelengths to provide maximum flexibility across a variety of network topologies. The use of Coarse Wave Division Multiplexing (CWDM) SFPs can be utilized to further increase the bandwidth capacity of the fiber infrastructure. The T1/E1NID must be used in pairs. A typical installation will include a chassis card installed in the ION Platform locally and a stand-alone device installed at the remote location. - Remote in-band management - Local or Remote Loopbacks - Copper or Fiber - Switch selectable for T1 or E1 - Remote firmware upgrade - LEDs for immediate visual status - Supports dual or single fiber - Supports multimode and single mode fiber at a variety of distances - Supports CWDM SFPs - SNMP management when used with ION chassis and management module - Remote standalone can be managed by local peer
