Systems and methods for transferring or conferencing a call between user-accessible communication endpoints are provided. The optical recording medium has a recording layer composed of a plurality of elements, and the recording layer contains Sb, and also has an Mn content of more than 20 atomic % but not more than 40 atomic %, on condition that the total amount of all the elements composing the recording layer is 100 atomic %. The sample tube receiving structures can be releasably locked relative to a support wall of the frame, thereby substantially immobilizing sample tubes that are held by the sample carrier. After delivery, the stabilizer expands to a functional configuration where it interfaces with the probe head and stabilizes and adjustably feeds the mesh strap for suturing while maintaining stabilization of the mesh on the vaginal apex and while keeping excess mesh from obscuring the surgeons view. The sterilization temperature and the sterilization time are selected such that after terminating the heating, the antiseptic solution is sterile and has a post-sterilization purity of at least about 92% and the percentage point change in purity from the initial purity to the post-sterilization purity is at most about 5%. The system is characterised in that it comprises a generating circuit for activating a wait signal to be forwarded to the control device during reading operations in such a way as to indicate the non-availability of the data to be read.
