Timing Mode—Choose External if the ONS 15454 derives its timing from a BITS source wired to
the backplane pins (ANSI) or a MIC-C/T/P FMEC (ETSI); choose Line if timing is derived from an
OSC-CSM or OSCM card that is optically connected to the timing node. A third option, Mixed,
allows you to set external and line timing references.
Because Mixed timing might cause timing loops, Cisco does not recommend its use. Use this

mode with care.
SSM Message Set—For DWDM nodes, choose the Generation 2 synchronization status messaging
(SSM) option. Generation 1 is used only by SONET or SDH ONS 15454s that are connected to
equipment that does not support Generation 2.
