1 Descriptions 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.
Descriptions DNI-3 User Manual SYSTEM-LEVEL APPLICATIONS This illustration shows a DNI-3 within a typical telecommunications network.
2 Installation INSTALLATION CONSIDERATIONS Location and Space The DNI-3 panel mounts flush into both unequal-flange and equal-flange (EIA or WECO) 23" (58.4 cm) network bays. The primary limiting factor of a DNI-3 rack configuration is the number of cables a network bay can accommodate. (The DNI can accommodate 1280 coax cables.) NOTE Telect recommends a maximum of 14 DNI-3 panels per bay, regardless of bay capacity, for easy access and adequate room for cable routing.

Secure the DCS OUT cables to the wire management tray via the tie-down slots. 9. Route the NE IN cables to the same side of the network bay as the DCS IN cables. Tie-wrap the cables in place within the extender panel cable management brackets. 10.
3 Electrical Operation DATA SIGNALS The DCS circuit cables terminate at the lower pair of termination points on the rear of the DNI-3 panel, labeled NE-1. The OUT cable connects to the upper NE-1 termination point and the IN cable connects to the lower NE-1 termination point. The NE circuit cables terminate at the upper pair of termination points on the rear of the DNI-3 panel, labeled NE-2.
Electrical Operation DNI-3 User Manual Inserting a Mini-WECO patch cord into the upper monitor Twist Lok Jack (TLJ) on the front of the DNI-3 panel accesses the NE circuit. Inserting a Mini-WECO patch cord into the lower monitor TLJ on the front of the DNI-3 panel accesses the DCS circuit. 3-2 Telect, Inc.
4 User Functions IN-SERVICE PATCHING To temporarily connect an NE or DCS circuit to an alternate DCS or NE circuit on the same or a different DNI-3 panel or DSX without disrupting service, follow the steps below, using the Twist Lok Jacks (TLJs) on the front of the appropriate DNI-3 panels and the following additional equipment: • • • Four Mini-WECO patch cords (Mini-WECO plug at each end) Two 75-ohm Mini-WECO terminating plugs One dual bridging office repeater (BOR), or two single BORs Step Action 1.
User Functions DNI-3 User Manual 4. Using a fourth Mini-WECO patch cord: a. Insert the plug of one end into BOR position 2, OUTPUT. b. Insert the plug of the other end into the IN TLJ at the first location. 5. Insert a Mini-WECO terminating plug into the OUT TLJ at the first location. 6. Insert a second Mini-WECO terminating plug into the OUT TLJ at the second location.
DNI-3 User Manual User Functions Step Action 1. Using one Mini-WECO patch cord: a. Insert the plug of one end into the IN TLJ at the first location. b. Insert the plug of the other end into the OUT TLJ at the second location. 2. Using a second Mini-WECO patch cord: a. Insert the plug of one end into the OUT TLJ at the first location. b. Insert the plug of the other end into the IN TLJ at the second location.
User Functions DNI-3 User Manual Step Action 1. To monitor the NE circuit outputs, insert a Mini-WECO patch cord into the NE (upper) Monitor TLJ. To monitor the DCS circuit outputs, insert a Mini-WECO patch cord into the DCS (lower) Monitor TLJ. 2. 4-4 Telect, Inc.
