Livingston Portmaster 3¶laforge bought two Livingston Portmaster 3 PM3A-1E, which are RAS (Remote Access Server) that
- terminates one 1E line (30 B-channels)
- provides ISDN dial-up on those channels
- provides DSP based modems in case analog modem calls should be handled.
More details to follow.
Spare Parts / Mods¶
The original fan is aFonsan DFB0812M (DC 12V 0.1A) fan by DELTA ELECTRONICS INC. The specs seem to state 2600 RPM / 24.8 dB(A) / 29 cfm.
I found it too noisy and replaced it with a Noctua NF-A8 FLX with L.N.A (reduced to 1650 rpm / 12.9 dB(A) / 24 cfm)
Fun fact: The PM3 actually seems to have a 5V -> 12V DC/DC upconverter just for the fan - instead of simply using a 5V fan...
