Network Managers Can Breathe a Sigh of Relief - Secure, Remote Network Management Just got Easier!

Transition Networks Drives New Standard in Optical Networking With Global Availability of ION Platform

LONDON, November 4, 2010 - Transition Networks Inc., the fiber access technology expert, a wholly
owned subsidiary of Communications Systems, Inc. (NASDAQ-GM: JCS), today
announced the global availability of The ION Platform, a new family of
intelligent optical networking devices designed to drive a new standard in
optical networking. Built to meet the increasing demand of today's networks,
the ION takes manageability and security in optical networking to a new
level. Network managers can now take advantage of fiber technology without
having to compromise on reliability, scalability or security, and they can do
it at a cost savings.

With the growing demand for Ethernet services, the new ION platform
enables service providers to offer tiered services with end-to-end Service
Level Agreements (SLAs), while increasing customer satisfaction and keeping
capital expenses (CapEx) to a minimum.

"Our customers demand more manageability and security as their networks
expand and become more complex," said Patrick Schaber, Director of Marketing
at Transition Networks. "The ION platform is our next leap in innovation for
delivering high-quality, reliable and scalable network devices."

Product Features

A typical application would include the ION chassis, an ION management
module and a redundant power supply. A variety of Fast Ethernet and Gigabit
Ethernet fiber network interface devices (NID) are also available to meet
customers' specific network requirements. All slide-in modules are designed
to help network managers reduce the cost of their fiber integration projects
by protecting the investments made in current copper based devices, while
still allowing them to experience the benefits offered by fiber optic
cabling.

The ION NIDs support up to 10k jumbo frames and bandwidth allocation to
limit upstream and downstream traffic. The ION NIDs offer complete Ethernet
OAM support including 802.3ah (Link OAM). The x3230 series include Ethernet
OAM support for 802.1ag (Service OAM) and Y.1731 (Performance Monitoring) to
ensure visibility across the entire network.

Configuration, management and monitoring of the ION NIDs can be performed
from a web-browser, command line interface (CLI), via telnet or the console
port, or with a 3rd party SNMP system.

Network Management

With the growing demand for network up-time, the use of a management
module in the ION chassis is essential. The management module allows remote
monitoring of the current status of each slide-in module. Each module has an
extensive set of features and functions that can be controlled. A network
administrator can securely configure, monitor, and troubleshoot each numbered
ION slide-in-module remotely through a web-browser, a command line interface
(CLI), via telnet, or with a third party SNMP application. Secure access
control to the management module is provided by support via management VLAN,
SSH, SSL, 802.1x. and SNMPv1 and v2.

Backwards Compatibility

While The ION Platform offers new levels for remote management, security,
and control, providing backwards compatibility to Transition Networks' Point
System installed base is a key feature customers will appreciate. By using
the ION Adapter on the Point System management modules and the Point System
converter modules, customers can install and manage their Point System
devices in he ION chassis, thus preserving their current investment in
Transition Networks products.

Product Configuration Transition Networks' Network Interface Devices are
available as a chassis card for The ION Platform or as standalone versions.
