AT-MC606 Port Descriptions
VDSL Line Port
The VDSL Line port features a BNC coaxial connector. It allows you to
connect two AT-MC606 VDSL Network Extender units together using an
existing internal building coaxial cable. One AT-MC606 VDSL Network
Extender is configured as a Provider unit and the other as a Subscriber
unit.
10Base-T/
100Base-Tx
Ethernet Port
The AT-MC606 VDSL Network Extender has one 10Base-T/100Base-Tx
Ethernet port which allows you to connect one AT-MC606 configured as a
Subscriber unit to an Ethernet device and a second AT-MC606 configured
as a Provider unit to an Ethernet Local Area Network (LAN) in the building
equipment room. This twisted pair port features an RJ-45 connector with a
maximum operating distance of 100 meters (328 feet). For the port pinout
details, refer to “RJ-45 Port Pinouts” on page 20.
Type of Cabling
The 10Base-T/100Base-TX Ethernet port is designed to operate with
unshielded twisted pair cables. For 10 Mbps operation, Category 3 or
better 100 ohm unshielded twisted pair cabling is required. For 100 Mbps
operation, Category 5 and Enhanced Category 5 (5E) 100 ohm unshielded
twisted pair cabling is recommended.
Auto MDI/MDI-X
A 10Base-T/100Base-TX Ethernet port on a network device can have one
of two possible wiring configurations: MDI or MDI-X. The Ethernet port on
a PC, router, or bridge is typically wired as MDI, while the twisted pair port
on a switch or hub is usually MDI-X.
The AT-MC606 Ethernet port features automatic MDI/MDI-X. The port
automatically determines the configuration of its end-node and then
configures itself appropriately. For example, if the AT-MC606 Ethernet
port is connected to a port on a bridge, which is typically wired as MDI, the
AT-MC606 VDSL Network Extender automatically configures the Ethernet
port to MDI-X. This feature allows you to use either straight-through or
crossover cables when connecting the AT-MC606 to other Ethernet
devices.
Auto-Negotiation
The AT-MC606 VDSL Network Extender auto-negotiates the speed and
duplex mode of the Ethernet link, so that the link comes up in the highest
performance configuration supported by both ends. For example, if an end
node is capable of only 10 Mbps, the AT-MC606 VDSL Network Extender
sets its Ethernet port to 10 Mbps or if an end node is capable of 100 Mbps,
