(NASDAQ-GM: JCS), today announced an expansion of its product return and warranty repair services for the European, Middle East and African (EMEA) region. When Transition Networks acquired Patapsco Communications of the UK, the company broadened its product portfolio and global presence. The Hampshire facility, gained in the acquisition, is located only 45 minutes from Heathrow Airport, significantly improving logistics and transit times for warranty products to be repaired and returned to service for EMEA customers. In 2011, Transition Networks introduced the same product replacement service from their Wales office that they offer in their US headquarters. This service for EMEA is now available at the returns facility in Hampshire. Transition Networks is again expanding and improving its service and support in response to the growing demand in EMEA for its products. “The addition of the Patapsco products and staff expanded our repair capabilities for the entire product catalog,” explained Director of Sales and Operations for EMEA, Dirk Steinkampf at Transition Networks. “Functional testing and product repair are now available in the Hampshire office, considerably reducing lead times for return of repaired products to our EMEA customers. Bringing our service and support capabilities closer to our European customers is a key step in continuing to support our international growth.” For more information about Transition Network’s products or service capabilities in Europe or other locations throughout the world, visit Transition Networks at www.transition.com.
