The Idle and PH Invalid encodings overlap Idle symbols received while the PLAYER
Idle Line State (ILS0 are not considered PH INVALID) Idle symbols received while the PLAYER
than ALS or ILS are treated as PH Invalid
PH DATA Request
The Ring Engine generates the 10-bit byte stream as defined in Table 8-2 Note that all symbol pairs are either control or data
symbol pairs Mixed data control symbol pairs are never generated or repeated by the Ring Engine
