TELEPHONE CONNECTION (XLT ONLY)
Basic Telephone Service
The Express XLT supports an analog DTMF telephone type (AT&T 2500) with
the POTS interface, part number 1200070L2. The telephone or other analog de-
vice (like a fax machine or modem) plugs into an RJ-11 jack labeled PHONE
located 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 XL/XLT on
a touch-tone telephone. Table 2-A explains how the flash-hook is used for han-
dling multi-call situations.
