Omnitron iConverter Modular T1/E1 Multiplexer

iConverter T1/E1 Modular MultiplexerThe iConverter Modular T1/E1 Multiplexer transports up to sixteen T1/E1 circuits and 10/100/1000 Ethernet over point-to-point fibre, CWDM channel or Ethernet Virtual Connection (EVC). This flexible and scalable system is comprised of an iConverter Fibre Transport module, and one or more iConverter 4xT1/E1 MUX modules installed in a 2, 5 or 19-module chassis.

Each iConverter Fibre 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 fibre 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 Fibre 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 Fibre Transport module is available with fixed-fibre 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.

Benefits Include

  • Multiple groups of mux modules can be installed in the same chassis
  • Optional connectivity to adjacent Ethernet switch modules
  • Remotely-managed configuration and testing enables rapid deployment
  • CLI management interface via TELNET or serial port
  • Manageable via SNMP with Omnitron’s NetOutlook® Management Software or third party software
  • Commercial (0 to 50º C ) and wide (-40 to 60º C) operating temperature ranges

iConverter Fibre Transport Modules

  • Fibre Transport modules are available for point-to-point Ethernet or Carrier Ethernet Virtual Connection (EVC)
  • Small Form Pluggable (SFP) or fixed fibre transceivers, in standard and CWDM wavelengths
  • Multimode, single-mode dual fibre and single-mode single-fibre options

iConverter 4xT1/E1 MUX Modules

  • Supports balanced T1/E1 or unbalanced E1
  • 24 hour T1/E1 statistic logging
  • In-band T1 loop-back
  • Out-of-band local loop-back on the copper and fibre ports, remote fibre loop-back and circuit test modes
  • Configurable alarm relay contacts for audio/visual fault notification
  • Easy configuration of T1/E1 line codes and line build-out
  • Optional external I/O clock port

Management

The T1/E1 Multiplexer system features integrated management.  Monitoring, configuration and remote testing functions can be accessed through the iConverter Fibre 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.

Application Examples

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 Centre, 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 fibre, and transport the multiplexed data over the fibre links.

At the Cell Sites, MUX groups are installed in 2-module or 5-module chassis. The fibre 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 NID 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 2-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).
