A reference to the corresponding terminating connection in
the table chmgrTConnectionTable in the Channel Manager MIB
(NETI-CHMGR-MIB) for the second established connection when 1+1
protection is used where the two channel originate from two
different trail termination points (TTPs). If the two
channels originate from the same TTP, then only one entry is
used in the chmgrTConnectionTable, referenced by
itsSnkTtpTConnection, and the value of this object is then
-1.
The value is the index into the table, i.e. the value of
chmgrTConnIndex.
