Dip Switch Configuration - Korenix JetCon 2502 User Manual

Connecting the communication port
CO (Central office) site: The RJ-11 port (Line) on the CO site should connect
to voice network – (PSTN); JetCon 2502 will modulate voice and Ethernet signal
into VDSL-2 signal and forward to CPE site by paired twisted cable through RJ-11
(VDSL-2 ) connector. During the communication, the LED will activate as different
operating status. Please refer to chapter 2-2 for LED description.
CPE (Customer premise equipment) site: the remote CPE site is the same
as CO site; the line port is connected to a POTS Phone and provides voice
communication.

4-2. Dip switch configuration

JetCon 2502 provides 4 DIP switches for system configuration; each DIP switch
has independent function. Please refer to the following description.
DIP Switch -1: Mode selection.
Master mode (On): Acts as Central office (master).
Slave mode (Off): Acts as remote office (slave).
Each JetCon 2502's mode should correspond to central (master) or remote (slave)
installation. The default setting is slave mode (off)
DIP Switch-2: Impulse Protection.
The impulse protection can deliver better communication quality under 250ms
duration of noise when configuring this function; the stream will have longer
forwarding latency.
On: Interleave mode with six ms forwarding latency time.
Off: Fast mode with one ms forwarding latency time.
DIP Switch-3: Symmetric.
Symmetric mode (Off): Upstream and downstream with same data forwarding rate.
The default setting is "Off".
Asymmetric mode (On): Upstream and downstream with different data forwarding
rate.
DIP Switch-4: SNR (Signal to Noise Ratio)
SNR (On): Better channel noise protection with SNR up to 9 dB.
SNR (Off): Original channel noise protection with 6 dB SNR. (Default setting)
Activate these functions when JetCon 2502 is allocated or installed in
environments with huge electric static or electric magnetic interferences.
