A. 10BaseT Connector Specification
The 10BaseT connector located on the back panel of the Cordless Gateway is
wired like a cabling hub. Standard 10BaseT specifications apply to the
10BaseT interface of the Symphony-HRF Cordless Gateway. No segment
may exceed 100 meters.
Use a standard 10BaseT cable to connect the Cordless Gateway directly to an
Ethernet Card, to a network router, or to the chaining port of an Ethernet hub
(also called the uplink port). Use a 10BaseT crossover cable to connect the
Cordless Gateway directly to a port on an Ethernet hub or to a device wired
like a hub, such as an ISDN router or cable modem. A 10BaseT crossover
cable is included in the product package; a standard 10BaseT cable is not
included. Also, you can monitor the Link LED to determine whether or not
you are using the appropriate cable. Refer to Chapter 3 for details.
A crossover cable differs from a standard 10BaseT cable in that pins 1 and 3
and pins 2 and 6 are crossed. These pins control the transmission and receipt
of data. Figure 7 below illustrates the pinout for a 10BaseT crossover cable.
