Newer versions of the MTS 2 and MTS 4 Junction Panels contain breakouts for Ethernet Site Link
connectors (Link1 and Link2). In order to gain Ethernet site link functionality on these newer versions
of Junction Panel, the breakout(s) needs to be removed and a RJ45 coupler needs to be inserted. For
more information on placement on the Junction Panel, See
Connectors on the MTS 2 Junction Panel" on page 4-53
Ethernet Site Link Connectors on the MTS 4 Junction Panel" on page 4-54
Previous version of the MTS 2 Junction Panel contain no breakout while the previous version of the
MTS 4 Junction Panel contain an AUX breakout. In order to gain Ethernet site link functionality
on those previous versions of MTS 2 and MTS 4 Junction Panels, a MTS Ethernet Retrofit Kit
is needed, see
The Link1 and Link2 connectors on the Junction Panel (or via the MTS Ethernet Retrofit kit) are
connected with the Site Controller through an internal extension cable.
For more information, see
Table 4-7 show the pin assignment for Ethernet Site Link connection.
The Ethernet Site Link MDIX connector pin out described in
Link1 and Link2. Be aware that the Pin definitions on the Site Controller are different from
the Link1 and Link2 connectors on the Junction Panel.

Ethernet Site Link Retrofit Kit
The Ethernet Site Link Retrofit kit is used convert one E1 output to two Ethernet outputs on
MTS 2 Junction Panels not equipped with such Ethernet outputs in order to get Ethernet Site-link
functionality. On MTS 4 Junction Panels, the Ethernet Site link Retrofit kit is used to convert
existing E1 and AUX outputs in order to get Ethernet site link functionality.
