Appendix D – Interface Connections
D-1 Introduction
This appendix provides the pin number assignment and wiring information for the connectors on
the EX-5i. All connectors are shown as viewed from the radio front panel.
D-2 T1/E1
Connections
There are two orientations of T1/E1 connections. Channels 1 and 2 have the securing tab towards
the top of the connector while Channels 3 and 4 have the securing tab towards the bottom of the
connector. The figure below illustrates the pin orientation and functionality of these connectors.

D-3 Ethernet
Connections
There are two orientations of Ethernet connections. AUX has the securing tab towards the top of
the connector while MAIN has the securing tab towards the bottom of the connector. The figure
below illustrates the pin orientation and functionality of these connectors.
The Ethernet connections of the EX-5i implement Auto-MDIX, and therefore either ‘straight’ or
‘crossover’ Ethernet cables may be used, independent of the wiring of the connected device.

Depending on the settings of in-band or out-of-band NMS, both the MAIN and AUX ports will
be able to access the far-end radio (if in-band) or not (out-of-band). In the case of out-of-band
