7.2.2 AT&T SYSTEM 75 REQUIREMENTS
The AT&T System 75 installation requirements are divided into three categories: Hardware, Software and
Configuration.
Hardware Requirements
The System 75 hardware interface for the Octel 200/300 with Adaptive Integration requires both analog
lines (for the Octel 200/300 ports) and digital lines (for the ATTIC links).
Analog Single Line Extensions. The System 75 must provide analog telephone ports (single line
-
extension, 2500 type) from its analog line circuit cards (part no. TN742 or TN746) for each port in
the cabinet.
Digital Voice Terminal Extensions. The System 75 must provide a digital voice terminal port for
-
each ATTIC link in the Octel 200/300 If two or more AT&T digital line cards (part no. TN754B) are
available, having each digital link on a different digital line card in the DEFINITY G3i provides
greater reliability.
