th
5 bit: DIP-switch for FPT
When FPT is disabled, it is identical to the AIS function of traditional optical multiplexers. When the
receiving signals of the E1 interface at the remote site are lost, the corresponding local E1 interface will
output all "1" signals; when the receiving signals of the local optical interface are lost, all local E1
interfaces will output all "1" signals.
FPT is designed for users who have special requirements. When FPT is enabled, if there is alarm of
LOS on any direction of optical interface£ ¬ E1 interfaces on both sides will not output HDB3 code. In this
case, there will be LOS alarm, rather than AIS alarm, on downstream E1 terminal devices (e.g. Switches,
converters or SDH devices).
