83 DSSU - Device switch of switching unit


Restrictions	Functions of the AMO	Error Messages and Advisories
Interrelationships	Parameter Description

Using AMO DSSU, devices of the switching unit (SWU) can be switched on or off (activated/deactivated). Using restart the functions deactivate and activate are combined. Additionally, devices may be signed off or signed on to a pen (Feature Autoset Relocate). In this AMO description, the term ’devices’ includes station lines, terminals, and trunks.

Devices may be switched, identified by their port equipment number (TYPE = PEN) or station number (TYPE = STNO).
For configuration of devices with different services for one station number (e.g. S0-Bus) these services may be switched individual.

All functional devices for S0-Bus can only be switched together. Parameter SVC is not allowed.

For display dependability states use AMO SDSU.

MSN station numbers:

This AMO enables the switch on and switch off for CP of MSN station numbers/MSN secondary stations numbers. To do this, the new service MSN was added. If service=MSN is used for a NON-MSN station number/MSN secondary station number the error message F23 will be displayed. Switch on is only allowed with ONTYPE=ANL, whereby the READY-Bit in CP is set. For switch off with OFFTYPE=DC the READY-Bit will be reset, with OFFTYPE=DI CP will be forced additionally to cancel all transactions of MSN station number immediately.
(please see AMO-SBCSU also)

B-channel of S0-Trunk circuit:

The second B-channel of S0-Trunk circuit can be switched individually. Switch on will be done by "activation with no loading", and switch off by "long term deactivation". If a non S0-Trunk circuit PEN is entered, message F22 will be displayed.
