The iConverter Modular T1/E1 Multiplexer transports up to sixteen T1/E1 circuits and 10/100/1000 Ethernet over point-to-point fiber, CWDM channel or Ethernet Virtual Connection (EVC). This flexible and scalable system is comprised of an iConverter Fiber Transport module, and one or more iConverter 4xT1/E1 MUX modules installed in a 2, 5 or 19-module chassis.
Each iConverter Fiber Transport module and up to four contiguous iConverter 4xT1/E1 MUX modules combine to form a MUX group. A MUX group can connect with another MUX group at the opposite end of a dedicated fiber link or EVC. A MUX group can also interoperate with a managed iConverter fixed-configuration T1/E1 Multiplexer.
Multiple MUX groups can be installed in a chassis, enabling high-density, star-topology deployments.
There are three Fiber Transport modules available: the iConverter TM3, the iConverter GM3 NID plug-in module and the iConverter GM4 NID plug-in module. The TM3 supports Ethernet Link OAM with IEEE 802.3ah. The GM3 and GM4 NID modules support Carrier Ethernet Service OAM with IEEE 802.1ag Connectivity Fault Management and ITU-T Y.1731 Performance Monitoring.
The Fiber Transport module is available with fixed-fiber or Small Form Pluggable (SFP) transceivers, and feature two Ethernet backplane ports for additional Ethernet connectivity to adjacent modules. A common application of this feature is to combine a 4-Port switch module in the adjacent slot to provide a solution with four additional 10/100/1000 ports.
The iConverter 4xT1/E1 MUX module supports four copper RJ-48 ports for balanced T1/E1 applications. Adapter cables are available to convert each RJ-48 interface to a BNC interface for unbalanced E1 transport applications.
The 4xT1/E1 MUX module features an optional external clock port that can be configured as a clock input or output. As an input, the port can be connected to an external clock source, such as a GPS receiver, to provide a common reference clock for the module. As an output, the port can provide the recovered T1/E1 clock from port 1 to other TDM equipment at the site.
The T1/E1 Multiplexer modules are part of the iConverter multiservice platform, and can be installed in a chassis equipped with iConverter Network Interface Devices, media converters, transponders and CWDM multiplexers. The multi-service platform is capable of delivering Ethernet, TDM, SONET and other services across a Wide Area Network. iConverter modules can be added to this scalable architecture to expand bandwidth capacity and add new services.
The iConverter Modular T1/E1 Multiplexer system is designed for service provider, enterprise, government and energy/utility networks.
Enterprise and government applications include extension of multiple T1/E1 circuits from a service provider demarcation point, and building-to-building PBX connectivity.
Service provider and utility applications include mobile backhaul and business services that require delivery of multiple T1/E1s and/or Ethernet.

Mobile Backhaul
In this application diagram, iConverter Modular T1/E1 Multiplexers deliver Ethernet and T1 mobile backhaul.
At the Mobile Switching Center, two iConverter MUX groups are installed in a high-density 19-module chassis, and connect to TDM and IP networks. The iConverter MUX groups convert RJ-45 Ethernet and T1 interfaces to fiber, and transport the multiplexed data over the fiber links.
At the Cell Sites, MUX groups are installed in 2-module or 5-module chassis. The fiber link with multiplexed data is converted back to RJ-45 Ethernet and T1 interfaces where they connect to the tower’s radio equipment.
Using the GM3 or GM4 Transport modules enables a seamless migration from 2G (T1s), to 3G (T1s and Ethernet), to 4G/LTE (Carrier Ethernet).

Ethernet and TDM Business Services
In this application diagram, iConverter Modular T1/E1 Multiplexers deliver Ethernet and T1s over an Ethernet Virtual Connection (EVC). A two module chassis with a GM4 Fiber Transport Module and a T1/E1 MUX module are installed at each customer location.
The EVC transports the business Ethernet and four T1 circuits between the two customer locations across a Carrier Ethernet network. The Ethernet transports business data, and the T1s are used for telephony services (PBX to PBX connectivity).
The T1/E1 Multiplexer system features integrated management. Monitoring, configuration and remote testing functions can be accessed through the iConverter Fiber Transport module serial console port, IP-based SNMP or IP-less OAM channels. Alarm relays and SNMP traps provide fault notification for loss of power, LOS and AIS.
SNMP management via NetOutlook provides a graphical user interface for real-time port and module information, local and remote configuration, and trap notification.
