You can connect whatever number of T1 Modem Bank units you want in each of 2 daisy chains,
as long as the total number of units in both daisy chains does not exceed 7 for each EPC/X host
adapter that will be installed in your computer. For example, all 7 of the units in Figure 9 could
be connected in one daisy chain, and there would be no units in the second daisy chain.
1. Use daisy chain cables to connect the HOST OUT port of each T1 Modem Bank to the HOST IN port of the T1
Modem Bank which is next in the chain.
2. Connect the terminator plug to HOST OUT on the last T1 Modem Bank in the rack to allow loopback to the
motherboard.
3. Label and secure all cables.
