The iConverter T3/E3 managed media converter is a member of the modular iConverter product family. It provides standard T3 (44.736Mbps) or E3 (34.368Mbps) coax to fiber conversion and can be used to connect to devices such as PBXs, multiplexers, routers and video servers via fiber. The T3/E3 operates in pairs extending distances over fiber, improving noise immunity and quality of service while improving intrusion protection and network security.

Being framing independent, the T3/E3 operates with framed or unframed data. It also operates with channelized or fractional unchannelized data streams. It supports B3ZS line coding for T3 (DS3) and HDB3 for E3.

iConverter T3/E3 models are available with multimode, single-mode and single-fiber options. Distances of up to 120km for single-mode dual fiber, 40km for single-mode single-fiber and 5km for multimode fiber are supported. The T3/E3 features ST, SC, LC and MT-RJ fiber connectors. The Small Form Pluggable (SFP) model supports a wide variety of SFP transceivers.

The T3/E3 supports standard RG-59, 75 ohm coax cabling. Line build-out is user selectable accommodating short-haul distances under 68.5 meters and long-haul distances up to 380 meters for T3 (DS3) and 440 meters for E3.

Individual coax and fiber port access can be controlled, providing the network administrator with an easy mechanism for controlling usage and access to the network.

The T3/E3 features extensive local and remote loopback userselectable diagnostic modes. Local loopback facilitates individual coax or fiber loopback operations. Remote loopback facilitates setting a remote T3/E3 converter to loopback mode, in order to test the integrity of the fiber and the remote converter.

Additional diagnostic features include forcing of all 1's data patterns (AIS) to the coax or fiber interfaces and generating and monitoring a Pseudo Random Bit Sequence (PRBS) per ITU O.151 specification. These diagnostic features combined with the informative and easy-to-read LED display facilitate quick installation, fault detection, isolation and correction.

iConverter T3/E3 modules are hot-swappable and can be mounted in a 19-Module (2U high) or 5-Module (1U high) rack-mountable chassis (19-inch or 23-inch) with any combination of redundant AC, 24VDC or 48VDC power supplies. They can also be mounted in a 2-Module AC or 18 to 60VDC powered chassis, or in a 1-Module AC/DC powered chassis.

Management is accomplished by using a Network Management Module (NMM) or a media converter with integrated management (such as an iConverter 10/100M2) that provides monitoring, remote configuration and trap notification. The management module can be accessed via SNMP, Telnet and via a serial port. The SNMP-based management is accomplished via Omnitron's intuitive, graphic-oriented NetOutlook management software or third party SNMP management software, while the Telnet and the serial interfaces have an easy-to-use, menu-driven interface.

Some of the real-time T3/E3 parameters that can be monitored include power, port link and data receive status, module operating modes, module type and model number, hardware and software revisions levels and serial numbers.

All of the T3/E3 hardware DIP-switch functions can be remotely configured via the software including protocol selection (T3/E3), line build-out options, port enable/disable control and all local and remote loopback and data patterns.

The T3/E3 module generates a wide variety of user-defined traps on port state changes, including link-ups and link-downs, AIS and PRBS data received, and upon entering and exiting the remote loopback mode. Monitoring of specific traps can be selectively enabled or disabled.

For wide temperature (-40 to 60º C), add a "W" to the end of the model number.
Consult factory for extended temperature (-40 to +75º C) models.
When using single-fiber (SF) media converter models, the Tx wavelength on one end has to match the Rx wavelength on the other.
*A minimum of 3dB of attenuation is required for these models.
**See SFP data sheet under Fast Ethernet for supported transceiver models.
