Register 02H configures the path termination mode of time-slots 1 to 8 of the T8TE.
TMODE1[1:0]-TMODE8[1:0]
The time-slot path termination mode select register bits (TMODE1[1:0]-TMODE8[1:0])
configures the mode settings for time-slots 1 to 8 of the T8TE. Time-slots are numbered in
order of transmission in the Incoming TeleCombus stream (ID[7:0]). Time-slot #1 is the first
byte transmitted and time-slot #12 is the last byte transmitted. The setting stored in
TMODEx[1:0] (x can be 1-12) determines which set of TeleCombus control signals are to be
encoded in 8B/10B characters.
In TeleCombus mode, the T8TE encodes TeleCombus control signals such as transport frame
and payload boundaries, pointer justification events and alarm conditions into three levels of
an extended set of 8B/10B characters as well as performing the IEEE mode conversion on
data. The two hierarchical levels are High-order Path Termination (HPT) and Low-order Path
Termination (LPT). For correct operation see table below:
