Expansion Cabinet Connections

With an Expansion Cabinet, a site may be increased by up to four Base Radios per Expansion
Cabinet. The MTS 4 Expansion Cabinet can be placed on either the left side of the MTS 4 Prime
Cabinet or on the right side. Different scenarios of connecting the MTS 4 Expansion Cabinet with the
MTS 4 Prime Cabinet are described in the following sections.

TX Connections

Depending on the Prime Cabinet configuration, TX connections between the MTS 4 Prime Cabinet and
the MTS 4 Expansion Cabinet can be configured in two ways:
• Combining eight channels onto one Duplexer/Post Filter in the MTS 4 Prime Cabinet using a
phasing harness.
• Combining four channels from the MTS 4 Prime Cabinet onto one Duplexer/Post Filter in the Prime
Cabinet and combining four channels from the MTS 4 Expansion Cabinet onto another Duplexer/
Post Filter in the Prime Cabinet.
In Figure 59: Connection Between MTS 4 Prime Cabinet and MTS 4 Expansion Cabinet – Phasing
Harness on page 119, all the eight channels (four channels from MTS 4 Prime Cabinet and four
channels from MTS 4 Expansion Cabinet) are combined using a phasing harness and connected to
one Duplexer/Post Filter in the MTS 4 Prime Cabinet.
