FITL Interface (HDOS OU)
Optical Units in the HDOS are assigned according to the number of MSDTs
supported. One single (transmit and receive functions on the same fiber), single-
mode fiber, terminated with a
ST connector, is connected to the rear HDOS shelf
position (J1 through J39). This shelf position is occupied by an OU assigned to a
particular MSDT server in the MDS. Refer to Table 3-2 in Chapter 3 for the
complete OU/MSDT Server assignments. Cross connections at the
LGX are
made to the optical line system associated with the remote MSDT.
