DIGITAL NETWORK INTERFACE PANEL
Telect’s DNI-3 is a multifunction support panel for DS3 telecommunica-
tions networks. It is an accessible and centralized interconnect point be-
tween digital cross-connect systems (DCSs) and central office network ele-
ments (NEs).
The DNI-3 panel serves as a platform for circuit configuration changes,
maintenance activities, and troubleshooting procedures. The DNI-3 be-
comes an extension of the DCS backplane that provides complete circuit
access, thus removing the risk of interrupting DCS operations.
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
Features
• Mini-WECO Twist Lok™ jacks (TLJs)
• Circuit designation labels
• Hinged designation holders

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.
Here are the DNI-3 space requirements:

In the above table, the first shaded row is the capacity for a 7-ft bay. The
second shaded row is the capacity for an 8-ft bay; the last shaded row is for
an 11.5-ft bay.
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 se-
cure and channel the circuit
cables. Telect recommends
two extender panels for each
fully provisioned DNI-3 net-
work bay. This provides ade-
quate cable routing space for
cables going to and coming
from the DNI-3 network bay.

No special tools or equip-
ment are required.

INSTALLATION PROCEDURE
Step Action
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 network 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 man-
agement 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 ex-
tender panel cable management brackets.
13. Starting at the lowest DNI-3 panel and working upward, connect
the NE OUT cables to the NE-2 OUT termination points on the rear
of the DNI-3 panels.
14. Secure the NE OUT cables to the tie-down bar.
