Which scattered single-service devices can the IDM MINI8 4+1 slot mixed-insertion PCM multiplexer replace?

The IDM MINI8 4+1 slot mixed-insertion PCM multiplexer integrates one E1 channel on the line side and multiple 64 kbit/s service interfaces on the user side into a single 19-inch 1U chassis, with the service cards configured according to the site service list. At a site where only one E1 is reserved on the line side while dispatch telephones, magneto telephones, audio trunks and telecontrol serial port data have to be connected on site, a telephone access device, a magneto access device and a serial port data device previously had to be configured separately; the IDM MINI8 implements these services on separate service cards inserted into the same chassis, so on the user side there is no need to lay separate cables or configure a separate device for each service type, and only 1U of cabinet space is occupied. Such integrated service access devices are commonly found in electric power substations, railway trackside equipment rooms as well as oilfield and mining field station buildings.
