Cabling the Optional RF Bypass Switch
The RF Bypass switch option supports modulated video and audio outputs for a variety of
configurations that enable you to meet the needs of individual subscribers.
The RF Bypass switch is a factory option and requires specific platform support software.
The RF Bypass switch enables the cable signal to pass directly to a cable-ready TV, bypassing
the DCT*. The bypass mode is automatically initiated under one of three conditions: when the
DCT* loses power, when it is turned off from the front panel, or when the user manually
activates the switch by pressing the A/B key. If the DCT* loses power or is turned off, the
subscriber can continue viewing the clear analog channels on the cable system. Activating
bypass mode enables you to tape a tuned channel from the DCT* while watching a different
clear channel that is bypassed to the TV.
Proper RF Bypass operation requires:
!
Special configuration data from the addressable controller
!
Proper user interface settings in the Electronic Program Guide (EPG).
Figure 3-5 illustrates RF cabling to an optional VCR using the RF Bypass switch. When a VCR
is not present, install the supplied jumper cable from the
CONV OUT
to
CONV IN

Bypass switch.
