2.1.1.3 PSO Module Alternate II (US&S AFO) Frequency Data
Table 2-3 provides maximum operating distance and frequency grouping data for frequencies
used by US&S AFO units.
The maximum operating distances shown, are between transmitter and receiver track wire
connections for end-fed track circuits. For center-fed track circuits, double the distances given to
obtain the maximum receiver-to-receiver distance.
NOTE
The alternate frequencies depicted in Table 2-3 are those typically used
by US&S equipment and are available for use with GCE. However, the
alternate frequencies use Siemens modulation patterns and are not
directly compatible with non- Siemens transmitters or receivers.
