Telephone Line Requirements
Generally, two telephone lines are required to ensure technical support for your
Express5800/320Ma 3.2 GHz or 3.6 GHz system:
•
One telephone line for use when calling for service
•
One analog telephone connection point for the modem
A 7-ft (2.13m) telephone cable, part number AW-B20245, is shipped with the
modem assembly.

1. If you implement ftGateway groups, you do not need
to supply telephone connection points for each
system. See "Site Planning for Systems in an
ftGateway Group"
Cable
24 AWG Unshielded Twisted Pair (UTP)
EIA/TIA-Verified, Category-3 or Category-5
wire, with RJ-45 modular connectors
terminated with pair-wiring adhering to the
EIA/TIA 568-A or EIA/TIA 568-B standard.
For connections to an Ethernet hub or switch,
provide a straight-through cable.
For 100- or 1000-Mbps (fast Ethernet)
operation, provide full-duplex, or Category-5
Ethernet cables.
The maximum allowable distance from an
Ethernet port to a switch or a hub is 100
meters (328 ft).
Multimode, 62.5- or 50-micron, DUAL fiber
cable with LC-type connectors to the PCI
adapter, and connectors on the other end that
are compatible with the network switch. The
maximum distance between the U574 PCI
adapter and a switch is 902 ft (275m).
