Minnetonka, Minn. January 13 -- /Marketwire/ -- Transition Networks Inc., the switching and conversion technology expert, a wholly owned subsidiary of Communications Systems, Inc. (NASDAQ:JCS), today announced the availability of a new fully-managed, high port count, Gigabit Ethernet switch. The unique features of this switch allow customers to leverage their existing 100Base-FX network infrastructure, while allowing support of future high-bandwidth network devices with IPv6 addressing.

The new switch provides (24) 10/100/1000Base-T copper ports and (4) Combo 10/100/1000Base-T or dual-speed (100/1000) SFP ports. Operating over an ambient temperature range of 0 to 40 degrees Celsius, it can forward 41.7 Mega packets-per-second over its 56 Gbps switching backplane. Eight hardware queues per port and an 8K MAC Address table support efficient processing and prioritization of data, allowing organizations to continue to reap the benefits of legacy network investments and maximize ROI.

"The new fan-less MILAN by Transition switch offers a standalone switching solution for high speed work groups in locations sensitive to ambient noise, such as hotel training suites, classrooms, small offices and corporate board rooms," said Patrick Schaber, Director of Marketing at Transition Networks. "This newest switch provides companies with a low-risk investment because its dual-speed SFP ports allow the switch to operate in legacy 100Base-FX fiber networks today, while supporting network upgrades to Gigabit speed in the future. Advanced security features and native IPv6 support means this switch will serve future network devices designed to take advantage of an exponentially greater amount of IP addresses in a more secure computing environment."

This latest MILAN by Transition switch offers full management features including SNMP v1, v2c, v3; LACP; Virtual LANs; traffic Prioritization and Quality-of-Service, including Ingress and Egress rate limiting; Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP), which supports redundancy per VLAN; IGMP for managing Multicast sessions; and Management interfaces via a local console, Telnet or the Web.

The ever-vigilant MIL-SM24T4DPA boasts many security features to protect communications and ensure data privacy. These include Access Control Lists (ACLs), IEEE 802.1x based access control, SSH/SSL, Web Management Encryption, RADIUS and TACACS+ support.
