SUPERSET Interface Module 2
The SUPERSET Interface Module 2 (SIM2) is an Analog Interface Module (AIM) which provides
analog interface functionality that lets you connect one or more 2-wire analog devices (such
as ONS telephones, fax machines, or modems) to the second B-channel of your
SUPERSET 4025, SUPERSET 4125, or SUPERSET 4150 telephone. The sum of the Ringer
Equivalence Numbers (REN) of all devices in the loop cannot exceed 2.0 REN. The analog
device has its own directory number and operates independently from the host telephone;
however, if you attach multiple analog devices in parallel, they share the second B-channel.
The analog device connects to the Analog/Fax/Modem interface on the SIM2/IM.
For installation instructions, see the SX-2000 Install Peripherals section of the Technical
Documentation CD-ROM.
