Connecting trunk pairs to media gateway
using jumper wires to establish 3-pair modularity
Figure 32: 3-pair modularity for trunk pairs for 1-pair trunks on page 67 and Figure 33: 3-pair
modularity for trunk pairs for 3-pair Tie trunks on page 68 show trunk pairs connected to the
media gateway with jumper wires to establish 3-pair modularity.
To connect the trunk pairs to the purple field:
1. Connect B25A cables between the network interface and the sneak fuse panels. See
Figure 32: 3-pair modularity for trunk pairs for 1-pair trunks
on page 67.
2. Connect A25D/B25A cables from the sneak fuse panels to the 110-type terminal block-type
connecting block connectors in the green field.
3. Connect 1-pair patch cords/jumper wires from each 110-type terminal block row in the green
field to the 110-type terminal block rows in the purple field for 1-pair central office (CO)
trunks or in Figure 33: 3-pair modularity for trunk pairs for 3-pair Tie trunks
on page 68 for
3-pair tie trunks.
