Transition Networks Unveils 802.1ag/Y.1731 Network Interface Devices Specifically Designed for Mobile Backhaul and Business Ethernet Service Delivery

s2250-s2350.gifCompany Adds to Network Interface Device Portfolio to Help Service Providers Reduce OpEx and CapEx When Providing Ethernet Services


Minneapolis, MN — May 13, 2009 — Transition Networks Inc., the fiber access technology expert, a wholly owned subsidiary of Communications Systems, Inc. (NASDAQ-GM: JCS), today announced the introduction of the S2250 and S3250 Network Interface Devices (NIDs). The S2250 and S3250 product families are specifically designed to help telecoms and cable providers to generate and preserve revenues when delivering Ethernet services. With the growing demand for business Ethernet services and mobile backhaul, these new NIDs enable 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. The S2250 and S3250 product families are Metro Ethernet Forum (MEF) 9 and 14 certified compliant and create a clear demarcation point between the provider and customer network, as well as carrier-to-carrier networks.


“Service providers are constantly looking for ways to provide more Ethernet services with SLAs, while reducing CapEx and OpEx,” said Patrick Schaber, Director of Marketing at Transition Networks. “Transition Networks continues to deliver carrier grade products that meet the CapEx and OpEx goals with the features service providers require such as; 802.3ah, 802.1ag, Y.1731, VLAN support, bandwidth allocation and remote diagnostics. Our newest products round out our extensive portfolio of network interface devices and provide service providers with cost-effective options to meet today’s demands.”


The S2250 and S3250 product families’ OAM capabilities ensure rapid detection and isolation of potential service related problems. The ability to have trouble detection and resolution from a central Network Operations Center (NOC) dramatically reduces operating expense (OpEx) and results in a quicker Mean Time to Repair (MTTR).


Product Features

With fan-less design, redundant power options and 1+1 protection the S2250 and S3250 product families are truly carrier grade products for use at customer premises, cell sites, central offices and aggregation nodes.


The S2250 and S3250 product families offer complete Ethernet OAM support including 802.1ag (CFM), Y.1731 (CFM & PM), 802.3ah (EFM) to ensure visibility across the entire network.


Service creation and traffic conditioning are easily done in the S2250 and S3250. E-Line, E-LAN and E-Tree services can be done directly at the demarcation point, including VLANs (S-Tag and C-Tag) and Class of Service (CoS) settings.


Bandwidth allocation can be used to limit all upstream and downstream traffic or by filtering criteria for the traffic. Traffic shaping in the S3250 allows for pre-conditioning of traffic to accelerate services and optimize access link bandwidth use by passing the highest priority traffic first.


The S2250 and S3250 offer a variety of intelligent loopbacks that operate at layer 1-2-3-4. These loopbacks can be defined by VLAN, MAC/IP addresses or any combination of layer 2-4 header criteria. The devices also respond to in-band loopback command from most Ethernet test sets and monitoring systems.


The S2250 and S3250 also have 10K jumbo frame support, redundant power options and SNMP V1 and V2c support.


Product Configuration

Transition Networks’ S2250 and S3250 family of Network Interface Devices are available as a standalone product. Transition Networks offers a variety of mounting options for the S2250 and S3250 family including 19 inch and 23 inch rack mount kits.

Transition Networks Unveils New Power-over-Ethernet Media Converter

sgpoe1040-100_l.jpgRounds Out Gigabit Ethernet PoE Media Converter Portfolio


Las Vegas, NV — September 29, 2008 – BICSI Fall Conference — Transition Networks Inc., the switching and conversion technology expert, a wholly owned subsidiary of Communications Systems, Inc. (NASDAQ: JCS), today announced the introduction of a new Gigabit Ethernet Power-over-Ethernet (PoE) media converter. This product expands Transition Networks’ portfolio of PoE copper-to-fiber media converters enabling customers to power wireless access points, voice over IP phones and IP security and surveillance cameras.


These new converters are capable of handling speeds up to Gigabit Ethernet and can be located more than 100 meters from the main PoE Power Sourcing Equipment (PSE) without the expensive replication of the PSE. The new devices are fully compliant IEEE 802.3af media converters providing 10/100/1000Base-T to 100/1000Base-X conversion and can be powered by an AC outlet anywhere in the world.


“In addition to helping overcome the challenge of linking remote IP cameras and Wi-Fi access points located beyond the 100 meter distance limitation of PoE over UTP cabling, our PoE copper-to-fiber media converters also help to reduce capital expenditures and installation costs by providing the benefits of PoE at the remote sites,” said Patrick Schaber, Director of Marketing at Transition Networks. “As we expand our PoE product portfolio to accommodate higher bandwidth devices and customer applications, the addition of the new gigabit Ethernet device offers customers the utmost in flexibility for integrating fiber into their PoE networks.”


Product Features

Transition’s AC powered PoE media converters utilize an external AC power supply allowing for a reduced form factor when compared to devices with an internal power supply. These converters combine the data received over a fiber optic link with up to 15.4 watts of power and insert the combination on either the “A” or “B” pairs of unshielded twisted pair cabling to interface with Data Terminal Equipment (DTE) Power Devices (PD). The media converters also include PD signature sensing and power monitoring features compliant with the IEEE 802.3af standard, such as Over-Current Protection, Under-Current Detection and Fault Protection Input. In addition, these products include Transition’s premium selectable features such as Automatic Link Restoration, Auto-Negotiation, Autocross, Link Pass Through, Far End Fault and Pause.


Transition also integrated the following innovative and industry-unique features into these new gigabit Ethernet media converters:


Power Device Reset - With the PSE/LPT switch enabled, a loss of fiber RX will disable PSE power output on the UTP port for 2 seconds to allow remote device to re-initialize. It will then resume power output to the PD device and will automatically re-establish the UTP communication link once the fiber RX is restored.

Redundant, dual speed SFP ports – The 110 model includes two SFP ports that support both 100Base-FX and 1000Base-X SFPs providing the ability to utilize this converter to support a fast Ethernet link today and simply move to gigabit Ethernet in the future by changing out the SFP. These dual speed ports can also be set via dip-switch to provide a redundant fiber path between a mission critical PD and a PSE or to function as traditional three port switch.


Product Configuration and Availability

Transition’s new gigabit Ethernet PoE media converters are offered in three distinct models:


Product Description

SGPOE10xx-100 10/100/1000Base-T (RJ-45) PoE to 1000Base-X (fixed fiber port) offered in either multimode and single mode SC

SGPOE1040-100 10/100/1000Base-T (RJ-45) PoE to 100/1000Base-X (dual speed SFP port)

SGPOE1040-110 10/100/1000Base-T (RJ-45) PoE to (2) 100/1000Base-X (dual speed SFP ports) offering fiber redundancy


These new gigabit Ethernet PoE media converters expand Transition’s already extensive portfolio of PoE products. Transition also offers external AC powered 10/100-base models as well as 10-base and 100-base PoE media converters with internal power supplies in either AC powered or DC powered configurations.
