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

s2250-s2350-b.jpgCompany 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.

Transition Networks’ S2250 and S3250 family of Network Interface Devices are available as a standalone product.
