Modem Connection; Network Connection; Twisted-Pair Cable - Asus S82A User Manual

Modem Connection

The telephone wire used to connect the Notebook PC's internal modem should have either two or four
wires (only two wires (telephone line #1) is used by the modem) and should have an RJ-11 connector
on both ends. Connect one end to the modem port and the other end to an analog telephone wall socket
(the ones found in residential buildings). Once the driver is setup, the modem is ready to use.
NOTE: When you are connected to an online service, do not place the Notebook PC in
suspend (or sleep mode) or else you will disconnect the modem connection.
Modem Protocols
The Notebook PC with internal modem complies with JATE (Japan), FCC (US, Canada, Korea, Taiwan,
and others), and CTR21 (see Appendix for supported countries) for almost worldwide protocol support.

Network Connection

Connect a network cable, with RJ-45 connectors on each end, to the modem/net-
work port on the Notebook PC and the other end to a hub or switch. For 100BASE-
TX speeds, your network cable must be category 5 (not category 3) with twisted-
pair wiring. If you plan on running the interface at 100Mbps, it must be connected
to a 100BASE-TX hub (not a 100BASE-T4 hub). For 10Base-T, use category 3, 4,
or 5 twisted-pair wiring. Duplex transfers (up to 200Mbps) is supported on this
Notebook PC but requires connection to a switch with "duplex" enabled. The soft-
ware default is to use the fastest setting so no user-intervention is required.

Twisted-Pair Cable

The cable used to connect the Ethernet card to a host (generally a Hub) is called a straight-through
Twisted Pair Ethernet (TPE). The end connectors are called RJ-45 connectors, which are not compat-
ible with the standard RJ-11 telephone connectors. If connecting two computers together without a hub
in between, a crossover twisted-pair is required.
