The TelecomBus mode registers (TMODE0[1:0]-TMODE11[1:0]) contain TelecomBus mode
settings for each STS-1 timeslot in the STS-12 stream. All STS-1 timeslots in all streams
must work in the same mode.
A S/UNI-2488 configured to be an APS protect device must have HPT mode enabled.
A S/UNI-2488 configured to be in cross-connect mode must be in MST mode so it can pass
the SONET/SDH overhead transparently.
The setting stored in TMODEx[1:0] (x can be 0-11) determines which set of TelecomBus
control signals are to be encoded in 8B/10B characters (see Section 13.1.12). Table 18 defines
the values for setting each mode.
