Ports
The AT-iMG606BD Multiservice Gateway has eight ports:
ˆ Six 10/100Base-T Ethernet (LAN) ports with RJ-45
connectors
ˆ One 100Base-FX fiber uplink (WAN) port with a simplex
SC connector
ˆ One Console port for local management
10/100Base-
TX Ports
The twisted pair ports are 10Base-T and 100Base-TX
compliant and are capable of 10 megabits per second
(Mbps) or 100 Mbps speeds. The ports are IEEE 802.3u
Auto-Negotiation compliant. With Auto-Negotiation, the
gateway automatically matches the highest possible
common speed between each gateway port and each end
node. For example, if an end node is capable of only 10
Mbps, the gateway sets the port connected to the end node
to 10 Mbps.
Each twisted pair port on the gateway can operate in either
half- or full-duplex mode. The twisted pair ports are IEEE
802.3u-compliant and will Auto-Negotiate the duplex mode
setting.
Note
In order for the gateway to set the duplex mode for
each port correctly, the end nodes that you connect to
the gateway ports should also use Auto-Negotiation.
Otherwise, a duplex mode mismatch can occur,
affecting network performance.
Each twisted pair port has a maximum operating distance of
100 m (328 feet).
For 10 Mbps operation, Category 3 or better 100 ohm
unshielded twisted pair cabling is required. For 100 or 1000
Mbps operation, Category 5 and Enhanced Category 5 (5E)
100 ohm unshielded twisted pair cabling is required.
The twisted pair ports are auto-MDI. They automatically
configure themselves as either MDI or MDI-X. This feature
allows you to use a straight-through cable to connect any
type of networking device to a port.
