DIGITAL NETWORK INTERFACE PANEL

Telect’s DNI-3 is a multifunction support panel for DS3 telecommunica­tions networks. It is an accessible and centralized interconnect point be­tween digital cross-connect systems (DCSs) and central office network ele­ments (NEs).
The DNI-3 panel serves as a platform for circuit configuration changes, maintenance activities, and troubleshooting procedures. The DNI-3 be­comes an extension of the DCS backplane that provides complete circuit access, thus removing the risk of interrupting DCS operations.
