TELEPHONE CONNECTION (L128T ONLY)
Basic Telephone Service
The Express L128T supports an analog DTMF telephone type (AT&T 2500)
with the POTS interface, part number 1202070L2. Two telephones or other an-
alog 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 conferencing,
call transfer, and call waiting are fully supported by the Express L128/L128T
on a touch-tone telephone. Table 2-A explains how the flash-hook is used for
handling multi-call situations.
