PHY PORT INTERFACE
The PHY Port Interface consists of I O signals used to connect the PLAYER
sublayer or other PLAYER
from one PHY Port Interface and the B Request and B Indicate paths from the second PHY Port Interface Each path
consists of an odd parity bit a control bit and two 4-bit symbols
Refer to section 3 3 the Configuration Switch for more information
