At DZS we pride ourselves on customer support. We know that our products are vital to your networks and to the customers whom you serve. We offer customers global 24 x 7 support as well as a variety of programs to ensure the highest level of response time.

The support portal is available globally to customers in need of product support. The portal allows you to submit service requests, submit an RMA request and obtain the status of your requests. In addition to our online ticketing system, you can speak directly with experienced support engineers either through our Technical Assistance Center or through our off hours support center.
