1 Descriptions DNI-1B Telect’s Bantam Digital Network Interface Panel—the DNI-1B, PN 0107128-5001 (128 circuit) and 010-7112-5001 (112 circuit)—is a central interface point for networks that connect DS-1 signals from digital crossconnect system (DCS) circuits to network element (NE) circuits. As an extension to the backplane of DCS equipment, the DNI-1B allows circuit configuration changes, maintenance, and troubleshooting without disrupting DCS operation.

2 Installation INSTALLATION CONSIDERATIONS Location and Space DNI-1B mounts flush into both unequal flange and equal flange (EIA or WECO) racks/bays—the 112-circuit version in 19" (48.3 cm) bays, the 128—circuit version in 23" (58.4 cm) bays. Rack configuration is limited mainly by the number of cables a bay can accommodate. Telect recommends a maximum of 22 DNI-1B panels per bay: • • • Allows easy access for maintenance. Keeps the panels within reach. Provides enough room for cable routing.

DNI-1B User Manual Installation Network Bay Extender Panel Telect recommends network bay extender panels for cable management— two for each fully provisioned DNI-1B bay. The extender provides 81 square inches (522.6 square cm) of routing space (enough for 135 30-pair ABAM cables) and 9 cable management brackets to secure and channel the cables. Extender Cable Management Bracket (Inside the Extender) Tools and Equipment Back View of Network Bay No special tools or equipment are required.
Installation DNI-1B User Manual INSTALLATION PROCEDURE Mounting the DNI-1B Step Action 1. Align the DNI-1B chassis mounting holes with the mounting holes of the network bay/rack. 2. Install four mounting screws (two on each side) into the mounting holes but do not completely tighten them. 3. Attach the hinged label holders to the front of the panel. a. Slip the eyehole in the center of the holder over the head of the top mounting screw. b.
DNI-1B User Manual Issue A Rev 2 Installation 6. Repeat Steps 2–5 for the DCS OUT cables, connecting them to the NE-1 OUT termination points. 7. Route the NE IN cables to the same side of the network bay as the DCS IN cables and the NE OUT cables to the same side as the DCS OUT cables. Tie-wrap the cables in place within the extender panel cable management brackets. 8.
3 Electrical Operation DCS wires attach to the lower four wire-wrap termination points on the rear of the DNI-1B panel (NE-1); the network element wires attach to the upper four points (NE-2). OUT (transmit) circuits attach to the upper pair of termination points; IN (receive) circuits attach to the lower pair.

4 User Functions PATCHING Step Action 1. Partially insert a dual Bantam patch-cord in the OUT and IN jacks of the appropriate NE-2 circuit on the front of the DNI1-B panel: OUT Side View of DNI1-B Panel Curved Side IN 2. Twist the plug on the other end of the cord so that its curved side is in the opposite orientation—if the first plug’s curved side is up, the second plug’s must be down. This is how you connect the IN of one circuit to the OUT of another.
