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.
