General Rules
Before making any connections to the IP DSLAM, note the following rules:
•
Ethernet Port (RJ-45)
All network connections to the IP DSLAM Ethernet port must be made using Category 5 UTP for 100Mbps,
Category 3, 4 UTP for 10Mbps.
No more than 100 meters of cabling may be use between the IP DSLAM or HUB and an end node.
•
VDSL Port (RJ-21)
All Home network connections to VDSL
1 X RJ-21 Cable (Male to Male) Using Pin 1 ~ 24, 26 ~ 49
RJ-21 Pin25 & 50 are not used.
Connecting the IP DSLAM
The 24-port VDSL IP DSLAM has 2 x GIGA Ethernet supporting full or half-duplex operation. The transmission mode
is using auto-negotiation. Therefore, the devices attached to these ports must support auto-negotiation unless they
will always operate at half duplex. If transmissions must run at full duplex, but the attached device does not support
auto-negotiation, then you should upgrade this device to a newer version that supports auto-negotiation.
Use “25” port connect to devices such as server, bridge or router. You can also cascade to another compatible MUX
or hub by connecting the 26 port to the other device.
