The iConverter 4xT1/E1 MUX multiplexs up to four T1/E1s and an optional 10/100 Ethernet onto a fiber optic transport link. The unmanaged T1/E1 Multiplexer provides an easy-to-use and cost-effective multi-service solution for providing TDM and Ethernet connectivity.

The iConverter 4xT1/E1 MUXes operate in a back-to-back configuration, with one multiplexer at each end of the fiber link. The 4xT1/E1 MUX transports services from legacy TDM equipment across long distances that exceed the reach or capacity of copper. This includes applications such as T1/E1 extension, mobile backhaul and building-to-building PBX connectivity, making it ideal for Enterprise, Telecom and Utility industries.

The 4xT1/E1 MUX supports Small Form Pluggable (SFP) transceivers, enabling adaptability to different fiber types and distances, and support CWDM and DWDM technology to increase the bandwidth capacity of fiber infrastructure.

The 4xT1/E1 MUX fixed fiber models support multimode and single-mode dual fiber with ST, SC and LC connectors; and single-mode single-fiber with SC connectors.

The 4xT1/E1 MUX supports standard T1, E1 and Primary Rate Interface (PRI), voice or data. The MUX also supports AMI, B8ZS and HDB3 line codes. DIP-switches provide easy configuration of the T1/E1 line codes and line build-out.

The copper interfaces feature four RJ-48 connectors for balanced T1/E1 applications. An optional adapter cable is available to convert each RJ-48 interface to a BNC interface for unbalanced E1 transport applications.

The 4xT1/E1 MUX features user-selectable local loop-back on both the copper and fiber ports, remote fiber loop-back and circuit test modes. This functionality facilitates diagnosis of the remote unit, and minimizes the need for test equipment and support personnel at each end of a link. Alarm relay and LEDs provide fault notification for loss of power, LOS and AIS.

The 4xT1/E1 MUX is a compact, unmanaged standalone unit available in both AC and DC models. The AC model accepts AC power input ranging from 100VAC to 240VAC, 50/60Hz, while the DC model accepts 18VDC to 60VDC.

Enterprise Application: PBX to PBX Connectivity

In this application diagram, iConverter 4x T1/E1 Multiplexers deliver four (4) T1s over a point-to-point fiber link. Compact 2-Module chassis are installed at each customer location.

At each end, the Alarm Relay can be connected to equipment to alert when there is a loss of power, LOS or AIS condition. Multimode or single-mode fiber can be used, and fiber links can be extended up to 120km using single-mode fiber.

Telecom Application: Mobile Backhaul

The following application shows an example of the iConverter 4xT1/E1 MUX used in a hybrid TDM/Ethernet transport network.

A wireless service provider has enhanced their network to support 3G/4G services. The new equipment uses Ethernet for backhaul at the Cell Site, while their existing legacy 2G equipment uses TDM (T1) for backhaul.

At the Base Station Controller (BSC) and Radio Network Controller (RNC), an iConverter 4xT1/E1 MUX is installed to extend the TDM and IP Networks to the Cell Site. The service provider is able to multiplex up to 4 T1/E1 circuits and one 10/100 optional Ethernet service on a common fiber link.

The fiber carries the multiplexed traffic to a second iConverter 4xT1/E1 MUX installed at the Cell Site where the T1/E1 circuits and Ethernet service provides connectivity to the equipment at the site.

Alarm Relay can be connected to equipment to alert when there is a loss of power, LOS or AIS condition. Alarm Relay connections are not shown.
