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.
The following Ethernet Site Link Retrofit Kits can be used for older versions of the Junction Panels
where Ethernet connectors are missing (only E1 present):
• GMKN4746A - for MTS 2 with new version of junction panel.
• GMKN4747A - for MTS 2 with old version of junction panel.
• GMKN4745A - for MTS 4 Prime Cabinet
• GMKN4744A - for MTS 4 Expansion Cabinet
NOTICE: GMKN4744A contains only the cables for the expansion cabinet. GMKN4745A
needs to be ordered separately for the MTS 4 Prime Cabinet.
