Function
Front Panel U8 Fiber optic detector
SW1 8-position DIP switch used to set FSU operating parameters as follows:
SW1-1 through SW1-4: Selects Data Rate in accordance with Table 6.
SW1-5: For 107460-1, -2 and -4,
Selects NORMAL or INVERTED Xmit Data Clock as follows:
Down = Normal Clock
Up = Inverted Clock
For 107460-3, SW1-5 must be UP
SW1-6: For 107460-1, -2 and -4 selects NORMAL or INVERTED
Receive Data Clock as follows:
Down = Normal Clock
Up = Inverted Clock
For 107460-3, SW1-6 must be DOWN
SW1-7: On 107460-1, -2 and –4 selects normal or inverted data as follows
Down = Inverted Data
Up = Normal Data
SW1-8: (This switch applies to G.703 only and is ignored by all other FSU
modules) Selects octet timing as follows:
Up = Octet Timing Enabled
Down = Octet Timing Disabled
DS4 Fiber optic emitter
DS5 DATA LED (green), illuminated when data is present on the electrical interface.
DS1 SYNC LED (green), illuminated when the optical signal is in sync.
DS2 YEL LED (yellow), Yellow Alarm Indication, illuminated when the remote fiber
receiver has failed and the remote transmitter is sending a yellow code by
the
local fiber receive channel.
DS3 PWR LED (green), illuminated when power is ON.
