The ltmdmnt.sys process is a system driver utility that is used by Microsoft Windows and the firmware packages and driver software distributions of certain data and fax modem devices from Alcatel-Lucent. The ltmdmnt.sys file is also used by the firmware components and driver software utilities of some data and fax modems from Agere Systems. This means the ltmdmnt.sys file is placed in the system upon the installation of these Alcatel-Lucent or Agere data/fax modem firmware resources and device driver software utilities, which also means the ltmdmnt.sys process is implemented into the installer distributions of these firmware and driver software applications. The specific data/fax modem device from Alcatel-Lucent that uses the ltmdmnt.sys file is the LT v92 Data+Fax Modem model, while the modem device model from Agere Systems that integrates the ltmdmnt.sys process as part of its firmware and driver software distributions is called Agere v92 Data+Fax Modem. The ltmdmnt.sys file and these associated Alcatel-Lucent and Agere Systems modem driver software utilities and firmware components are all embedded with support for widely used versions of Microsoft Windows.

Most non-system processes that are running can be stopped because they are not involved in running your operating system. ltmdmnt.sys. is used by LT v92 Data+Fax Modem Firmware/Driver Software and Agere Systems v92 Data+Fax Modem Firmware/Driver Software, If you shut down ltmdmnt.sys, it will likely start again at a later time either after you restart your computer or after an application start.

A process usually a part of an installed application such as LT v92 Data+Fax Modem Firmware/Driver Software and Agere Systems v92 Data+Fax Modem Firmware/Driver Software, or your operating system that is responsible for running in functions of that application. Some application require that they have processes running all the time so they can do things such as check for updates or notify you when you get an instant message. Some poorly written applications have many processes that run that may not be required and take up valuable processing power within your computer.
