The Norstar Analog Station Module with Message Waiting Indication (ASM with WMI) serves as an interface between a Norstar-PLUS Modular ICS and analog devices such as FAX machines, FAX Modems, credit card verification devices, as well as analog voice equipment.
The ASM is an 8 port module that connects to the Modular ICS unit via a Modular ICS Fiber Expansion Cartridge. Two ASMs may be daisy-chained together and connected to a single fiber receptacle on an expansion cartridge.
The ASM supports the same features and functionality as the ATA-2, and is equipped to provide stutter dial tone and/or visual message waiting indication on appropriately equipped analog terminal equipment. The ASM will support data modem transmission speeds up to 33.6 kb/s.
