The iConverter Modular T1/E1 Multiplexer transports up to sixteen T1/E1 circuits and 10/100/1000 Ethernet over pointto-point 1000Mbps fiber, CWDM/DWDM 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 connects 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 multi-service 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.

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 two different Providers. Each Provider is using a different clocking method by using the 4xT1/E1 MUX module with Clock I/O (8486-4). Provider 1 is using the NTR Clock at the Mobile Switching Center as the input clock to the MUX module and all T1/E1 circuits are synchronized to the incoming NTR clock. At the Cell Site 1, all T1/E1 circuits are loop timed. Provider 2 is using the GPS as the input clockto the MUX module and all T1/E1 circuits are synchronized to the incoming GPS clock. At the Mobile Switching Center, all T1/E1 circuits are loop timed.

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 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.

MUX groups support up to 16 T1/E1 circuits and can be installed in a 5-module chassis.

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 GM3 or GM4 NID 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.
