Transition Networks Delivers Enhanced 10/100/1000 Ethernet Converter

Expands Product Line With Additional Port Configurations

MINNEAPOLIS, MN--(Marketwire - April 29, 2008) - Transition Networks Inc., the conversion technology and switching expert, a wholly owned subsidiary of Communications Systems, Inc. (AMEX: JCS), today announced the introduction of its new, enhanced 10/100/1000 Ethernet converter series. These converters provide a flexible and cost-effective method for integrating legacy 10/100 UTP devices into a gigabit Ethernet fiber network. In addition, the enhanced feature set provides more functionality and more network management capabilities to network administrators.

"As the proliferation of gigabit Ethernet continues, Transition is pleased to enhance and expand our gigabit Ethernet converter portfolio in an ongoing effort to provide customers with a cost-effective methods for upgrading their networks," says Patrick Schaber, director of marketing at Transition Networks, "As always, Transition is committed to delivering feature-rich products offering our customers the utmost in flexibility by tailoring product options to their specific network needs."

New Product Features and configurations

The new GFEB-120 series of 10/100/1000Base-T to 1000Base-X Ethernet copper-to-fiber media converters replaces Transition's GFEB-100 series of media converters. With the new product line, customers benefit from new features like Bandwidth allocation, Virtual Cable Test on UTP port, IEEE 802.1q VLAN tagging and double tagging (Q in Q), IEEE 802.1P QoS, IPv4 Tos/DiffServ, IPv6 traffic class, Port-based VLAN to allow unidirectional transmission, RMON counters for each port, Digital Diagnostic Monitoring interface (DMI) and the ability to remotely update firmware.

These new converters are fully compatible with the previous models and also include those features found on the GFEB-100 series including AutoCross™, Auto-Negotiation (both UTP and fiber ports), Link Pass Through, Pause, Automatic Link Restoration and switch-selectable speeds.

In addition to the enhancement discussed above, four additional models with industry-unique port configurations will provide customers the greatest in flexibility and functionality:

  1.  The new GFEB-140 series offers a 10/100/1000Base-T UTP port and (2)
      1000Base-X SFP ports which can be set to operate independently or in
      a redundancy mode providing redundant fiber path protection with a
      switching time of < 50ms.
  2.  The new GFEB-180 series replaces the UTP port on the -140 series with
      a dual-speed SFP port thereby providing (1) 100/1000Base-X SFP port
      and (2) 1000Base-X SFP ports which can be set to operate
      independently or in a redundancy mode providing redundant fiber path
      protection with a switching time of < 50ms. The dual speed SFP port
      supports both 100Base-FX and 1000Base-X speeds as well as both fiber
      and/or UTP SFPs.
  3.  The new GFEB-150 series is a fiber-to-fiber converter with a fixed,
      100Base-FX port and a fixed, 1000Base-X port, providing the ability
      to bridge a 100Mb optical signal onto a gigabit Ethernet fiber
      backbone.
  4.  The new GFEB-170 series is a fiber-to-fiber converter with a fixed,
      100Base-FX port and a 1000Base-X SFP port, providing the ability to
      bridge a 100Mb optical signal onto a gigabit Ethernet fiber backbone.
