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.
TELEPHONE CONNECTION
Basic Telephone Service
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
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.
