Pinout of UTP Cable (RJ-45 to RJ-45)

The RJ-45 to RJ-45 Ethernet cable is used to connect the Ipnext190 with another device
(typically hub). The sequence of the RJ-45 connector pins is shown in below figure. For the
signals between the IPNext190 with another device and pinout specification, refer to Figure 4-1,
"Signals and Pinout of Serial Ethernet Cable".
The table above shows the specification of serial cables that connect the
1.
IPNext190 with the hub.
2. If you want to connect an IP-PBX with another IP-PBX or the gateway with the
PC, you should use cross cables.
