Digital Network Interface Panel:
64 Circuits (DNI-3)
User Manual
1.1 Overview: 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.
1.1.1 Capabilities
• High circuit densities (up to 1280 coax cables per panel)
• Efficient circuit migration for system expansion
• Quick circuit patching, troubleshooting, and monitoring
• Compatability with all DS3, STS1, and STS3 signal types and system management software
1.1.2 Features
• Mini-WECO Twist Lok™ jacks (TLJs)
• Circuit designation labels
• Hinged designation holders

1.3 Installation Considerations
1.3.1 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.

1.3.1.1 Network Bay Extender Panel
Each network bay extender panel provides 81
square inches (522.5 square cm) of cable routing
space (enough for 1280 RG59 cables). The panel
comes with nine cable management brackets that
secure and channel the circuit cables. Telect
recommends two extender panels for each fully
provisioned DNI-3 network bay. This provides
adequate cable routing space for cables going to
and coming from the DNI-3 network bay.
1.3.2 Tools and Equipment
No special tools or equipment are required.
1.4 Installation Procedure
1. Align the DNI-3 chassis mounting holes with the
mounting holes of the network bay.
2. Insert four 24 x 1/2" mounting screws (two on
each side) into the mounting holes and securely
tighten them.
3. Route the DCS IN cables to one side of the net-
work bay. Tie-wrap the cables in place within
the extender panel cable management brackets.
4. Starting at the lowest DNI-3 panel and working upward, connect the DCS IN cables to the
NE-1 IN termination points on the rear of the DNI-3 panels.
5. Secure the DCS IN cables to the wire management tray via the tie-down slots.
6. Route the DCS OUT cables to the opposite side of the network bay. Tie-wrap the cables in
place within the extender panel cable management brackets.
7. Starting at the lowest DNI-3 panel and working upward, connect the DCS OUT cables to the
NE-1 OUT termination points on the rear of the DNI-3 panels.
8. 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. Starting at the lowest DNI-3 panel and working upward, connect the NE IN cables to the NE-
2 IN termination points on the rear of the DNI-3 panels.
11. Secure the NE IN cables to the tie-down bar.
12. Route the NE OUT cables to the same side of the network bay as the DCS OUT cables. Tie-
wrap the cables in place within the extender panel cable management brackets.

1.5 Electrical Operation
1.5.1 Data Signals
The DCS circuit cables
terminate at the lower pair of
terminationpointsontherear
of the DNI-3 panel, labeled
NE-1. The OUT cable
connects to the upper NE-1
termination pont and the IN
cable connects to the lower
NE-1 termination point.
The NE circuit cables
terminate at the upper pair of
terminationpointsontherear
of the DNI-3 panel, labeled
NE-2. The OUT cable
connects to the upper NE-2
termination point and the IN
cable connects to the lower
NE-2 termination point.
Internally, the DCS circuits and the NE circuits are cross-connected.
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.
