The Dual A/B-RF Bypass module is commonly used in dual-cable systems. Both Cable A and
Cable B are cable signals coming from the service provider. The service provider determines
which source will be the return cable. Choose the cabling diagram that matches the return
configuration you need.
The Dual A/B cable system using a STARFONE module utilizes the telephone modem as the
return path to the service provider. Figure 3-9 illustrates a DCT 2000 with a STARFONE
module:
