FE1 to Ethernet Converter
Humanity HM-C108A E1 to Ethernet converter realizes Ethernet transmission over fractional or un-fractional E1 at the bandwidth of 64kbps~2048Kbps.
Main Feature:
- Ethernet transmission over E1
- Bandwidth configurable by DIP switch
- E1 both with BNC and RJ45
- AC or DC option

|
DIP switch |
DIP SEL1 = unframe/frame option switch. ON=Transparent mode (E1) OFF=Time slot mode(FE1) |
DIP SEL2 =Timing mode of E1 output ON=local timing OFF=recovery timing |
|
DIP SEL3=PCM30/31 mode configuration (valid under time slot mode) ON=PCM31 mode OFF=PCM30 mode NOTE: both converter at the both sides must be under the same mode |
|
DIP SEL4-8=Time slot setting switch: adopt binary system. (Valid under time slot mode) On stand for‘1’,Off stand for‘0’。 SEL:4 means highest,SEL:8 means lowest I.E.: SEL:4=OFF SEL:5=OFF SEL:6=ON SEL:7=ON SEL:8=ON Setting as above means that Ethernet data use 1~7 time slots NOTE: Time slots of both converter must be set as the same under time slot mode |
|
Power supply |
