Siemens S30122-K7403-T telecommunications hardware (Hicom/HiPath/OpenScape PBX, SDH transmission) PBX Card / Module

The Siemens S30122-K7403-T is an EXMR external music-on-hold module for the HiPath 3300, HiPath 3350, HiPath 3500 and HiPath 3550 systems. EXMR lets the PBX play music or announcements from an external source while a caller is on hold, connected via a screw terminal on the HiPath 3350/3550 wall-mount chassis or a front-panel RCA socket on the HiPath 3300/3500 rack chassis, the opposite approach to the self-contained MPPI musiphone module, which generates its own internal tone rather than taking an external feed. Sites choose EXMR specifically because they want their own branded audio, radio station or announcement on hold rather than a generic built-in tone. It is a small plug-in module rather than a line card, so its failure affects the caller-hold experience rather than call capacity. Genuine Siemens HiPath spares of this kind remain a routine requirement for maintaining feature parity on established installs. Confirm your chassis type (wall or rack) before ordering, since the connection method differs between them.
