CPU1
Processor Module
The processor module, CPU1 (Central Processing Unit) administers the configuration (programmes and parameters) of the DVS-21 system. It controls the interaction between the external interfaces, the slide-in modules and the PCM bus.
At a Glance:
Control and monitoring of DVS-21 functionality
Central parameterization of all system modules
4 system configurations on 4 memory banks, switchable
External clocking over 2 MBit/s (HDB3) or 2 MHz
DVS-21 system clock, can be synchronized to DCF77
Local and remote malfunction signals
Configurable over a serial V.24 interface
Configuration software runs on windows, also runs offline

Block diagram CPU1
The processor module administers up to 28 modules of a DVS-21 system. Communication with the modules is done through the bus system of the backplane.
- Card select (KS) 1 - 28: Addressing of the modules in the DVS-21 system
- PCM bus: 48 PCM user channels (duplex) A standby processor can be fitted on a special backplane variation as option. If the
active processor fails an automatic switching over to the standby CPU1 takes place.
The internal clock generator makes system clock signals available for the modules, the PCM bus and the external interfaces. It is possible to use an external 2 MBit/s, HDB3 signal (T2) or a 2 MHz clock signal (T3) for clock extraction. A clock signal thus generated is available to all systems belonging to a DVS-21 group.
The CPU1 works with the operating system “DVS-xx”. 2 firmware versions can be stored and arbitrarily activated.

The configuration software “ICS x.xx” offers the possibility of transferring or reading­out of up to 4 system configurations to/from the CPU1 over the serial V.24 interface (port 1) (Userbank 1 – Userbank 4).
The internal DVS-21 system clock can be updated by an external DCF77 receiver. If several DVS-21 systems are connected together as group then the synchronization of the system clocks of the systems in the group can be done with only one DCF77 receiver.
System configuration as well as the connecting of the DCF77 receiver is done over two potential-separated serial V.24 interfaces.
- Port 1: Connecting of a PC with the configuration software ICS (also possible from a remote location over modem)
- Port 2: Connection of a radio controlled clock (DCF77) to adjust system time (beginning with hardware version 6.01)
As long as the modem connection for remote configuration of the DVS-21 is
used, communication with the DCF77 receiver is interrupted.
