To connect to an NIC you will need a straight-through cable. To connect to 
another hub you will need an Ethernet crossover cable, unless the hub 
you are connecting to has a crossover switch. See Appendix D for 10BaseT 
connector pin assignments.

The Express 4110/4120 supports an analog DTMF telephone (type AT&T 
2500) with the POTS interface.  Two telephones or other analog devices 
(like a fax machine or modem) plug into either RJ-11 jack (labeled with 
drawings of telephones) on the rear of the unit.  Using a multipoint line 
allows the POTS and data port to have unique phone numbers. 

Supplementary services such as call holding, three- or six-way conferenc-
ing, call transfer, and call waiting are fully supported by the  Express 
4110/4120 on a touch-tone telephone. Table 2-1 explains how the flash-
hook is used for handling multi-call situations.
