Transition Networks Launches Carrier Grade Fiber Access Switch

SM24-100SFP-AH

New 24-port switch Delivers Secure Services,

while Maintaining and Managing Network Traffic with 802.3ah (OAM)


NXTcomm, Las Vegas — June 17, 2008 — Transition Networks Inc., the fiber access technology expert, a wholly owned subsidiary of Communications Systems, Inc. (NASDAQ-GM: JCS), today announced the introduction of a new 24-port fiber access switch. This product is the newest member of Transition Networks‘ portfolio of carrier-class products aimed at helping service providers deliver and manage critical service offerings. The new fiber switch has been designed with OAM (operations, administration and maintenance) capabilities to ease the management of delivering Carrier Ethernet and/or triple play services.


“As customers demand new product offerings and service level agreements, service providers need to find cost-effective ways to increase service availability while ensuring service quality. Products designed with Ethernet OAM (IEEE 802.3ah) are a means to address those challenges and provide carrier-class services over an Ethernet infrastructure,” said Patrick Schaber, Director of Marketing at Transition Networks. “Transition Networks offers a variety of OAM products designed specifically to interface with the new SM24-100SFP-AH switch.”


The SM24-100SFP-AH features a 1U form factor consisting of (24) 100Base-X SFP ports, (2) 10/100/1000 RJ-45 ports and (2) Gigabit combo ports. The 24 SFP ports accept industry standard 100BASE-X optical transceivers.


The SM24-100SFP-AH switch also includes Carrier Ethernet specific software, QoS and Management features which enable service providers to deliver secure services while checking end to end connectivity for customers. The SM24-100SFP–AH switch is a next generation switch designed to fulfill the needs of service providers.


Product Features and Benefits


Flexible Uplink Options

In addition to the (24) 100BASE-X ports the SM24-100SFP-AH has combo Gigabit uplink ports that allow copper or fiber connections to be used, depending on the network environment. The fiber ports are SFP and can accommodate a wide range of transceivers for your uplink requirements.

Carrier Ethernet Specific Software

The SM24-100SFP-AH switch was designed for use with Carrier Ethernet. Feature enhancements such as 802.3ah, Q-in-Q, Carrier Class Rate-Limit, QoS and subscriber isolation were added to help service providers deploy, manage and secure the network services they are delivering.

Single IP Management for 36 Switches

The SM24-100SFP-AH is managed as a single switch and has a single IP address. Up to 36 of the SM24-100SFP-AH switches can be virtually stacked and managed as a single switch while using only one IP address.

Enhanced Security Features

The SM24-100SFP-AH is designed to provide enhanced security and to prevent subscriber’s network traffic from affecting overall network performance. The SM24-100SFP-AH provides features such as Private VLAN, DHCP Snooping and IP Source Guard to help protect the subscriber’s traffic from affecting each other.


The SM24-100SFP-AH offers Storm Control Protection and Port Security to protect the switch from unwanted attacks and to ensure the switch CPU performs optimally.


To ensure only valid traffic is allowed through the switch the SM24-100SFP-AH includes IEEE 802.1x and L2/L3/L4 ACL rules to control traffic and validate the traffic going through the switch.

802.3ah OAM

In addition to a large user base, a service provider network can become very large and complex. The 802.3ah OAM capabilities of the SM24-100SFP-AH help service providers isolate, maintain and manage network traffic.
