FlexGain Plex is designed to meet the demand for simple and cost-effective TDM equipment providing access to voice and data services.

E1 leased line services and SHDSL links remain an important access network mean. With the FlexGain Plex operators can easily deliver data and voice services to their customers by using any TDM based transport network.

FlexGain Plex multiplexers are a flexible network element for enterprise or utility networks.
