Remote Management with a Stand-Alone Device When used in conjunction with a managed Point System(TM) chassis, this stand-alone unit can be managed remotely. The Remotely Managed T1/E1 copper to fiber media converter will provide a solution for users wh o desire to extend their T1/E1 or PRI circuits over fiber and remotely manage them "in-band" from admin locations


Extend distances over 2 km on multimode connections or over 80 km on single-mode fiber, Provide campus interconnects - With the exception of ethernet, T1/E1 is one of the most common campus/metropolitan area networking interconnects. A copper to fiber conversion on the premise side of the T1/E1 makes it easier to integrate voice traffic, frame relay or IP type traffic on your fiber network, Remote management - Stand-alone can be managed remotely when used with a managed chassis, Extend T1 networks - Extend T1 to other buildings in a campus or MAN from 2 - 80 km for voice or data application


  • Remote unit in-band management
  • Copper or fiber, local or remote loopbacks in software mode
  • Loopback switch facilitates local installation
  • Converts the copper ports on T1/E1 devices, such as a PBX or T1/E1 Router, to multimode or single-mode fiber
  • Extds distances 2000 m over multimode fiber or 80000 m over single-mode fiber
  • Switch selectable RJ48 connectors for T1 or E1
  • Jitter attenuators optimize Bit Error Rate (BER) performance
  • Network debug procedures make BER testing more convenient
  • Built-in oubleshooting with the addition of a selectable TAOS (Transmit All Ones) switch on the fiber and copper interfaces allows the network engineer to test all T1/E1 equipment on that network segment and ensure the network link
  • Dry relay contacts enable the media converter to be tied into a separate alarm circuit commonly found in a T1/E1 twisted pair environment. Contacts will be activated on loss of power or loss of fiber link
  • An LED provides Alarm Indication Signal (AIS)
  • Can be used with fractional T1/E1 circuits
  • Report converter status: Copper and fiber link status, hardware switch settings: LBO, AIS copper, AIS fiber, HW/SW, AIS detected copper and fiber, model number, copper and fiber connector
  • Remote commands: Loop-back copper and fiber, AIS transmitted on fiber on loss of copper link, AIS transmitted on copper on loss of fiber link
  • Extend PRI over fiber
