iConverter T3/E3

T3/E3 Managed Media Converter

The iConverter T3/E3 media converter 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. T3/E3 media converters operate in pairs, extending distances over fiber, which improves noise immunity, quality of service, intrusion protection and network security.

The iConverter T3/E3 media converter 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. T3/E3 media converters operate in pairs, extending distances over fiber, which improves noise immunity, quality of service, intrusion protection and network security.

The T3/E3 supports fixed fiber and Small Form Pluggable (SFP) transceivers, enabling adaptability to different fiber types, distances and wavelengths, providing maximum flexibility across a variety of network architectures and topologies. Support for SFP transceivers increases the bandwidth capacity of fiber access infrastructure by incorporating Coarse Wave Division Multiplexing (CWDM) technology. CWDM SFPs provide wavelength conversion enabling multiplexing of up to 16 wavelengths on the same fiber pair. The same media converter can utilize a variety of SFPs for different wavelengths and distances, reducing costs and simplifying inventories.

The T3/E3 also supports a variety of fixed fiber connectors for multimode, single-mode and single-mode single-fiber.

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 when installed in a chassis with network management.

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, eliminating the cost of external hardware or support personnel at each end of the link.

Additional diagnostic features include forcing of all 1s data patterns, Alarm Indication Signal (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.

The iConverter T3/E3 is available as a compact, unmanaged standalone unit or as a chassis managed plug-in module. The hot-swappable plug-in module 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. It can also be mounted in a 2-Module AC or 18 to 60VDC powered chassis, or in a 1-Module AC/DC powered chassis.

As a standalone unit, the T3/E3 is available as a wall-mount unit. The wall-mount models are DC powered and are available with an external AC/DC power adapter or a terminal connector for DC power.

T3/E3 media converter provides a cost-effective solution for extending telecom demarcation points. A pair of T3/E3 converters is used to extend the demarcation between buildings via fiber. Multimode or single-mode fiber can be used, and fiber links can be extended up to 120km using single-mode fiber.

Management of the plug-in module is accomplished by using a Management Module1 (such as an iConverter NMM2 or 10/100M2) that provides monitoring, configuration and trap notification. The management module can be accessed via SNMP, Telnet, or 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-up and link-down, AIS and PRBS data received, and upon entering and exiting the remote loopback mode. Monitoring of specific traps can be selectively enabled or disabled.

1 For complete management support, use a M2 series module (NMM2, GX/TM2, 2GXM2, 10/100M2, 2FXM2) or higher.
