Fifth priority link for synchronisation

This command defines which link will have the fifth priority to be master.

When there is a digital connection between at least two systems, it is essential that all systems are synchronised to the same master clock.

A digital connection may consist of any types of CCS trunk, CAS trunk as well as a system with integrated cordless.

These commands define which digital link is used for synchronisation of system clocks as well as the priority which working link is taken for the synchronisation purpose in case of failure.

Only digital links which are programmed in USER/SLAVE mode (see command 1912 Termination in ASB 150 Termination in ASB15002) are allowed to be used for synchronisation purpose!

If a system is equiped with ICCU (2) only, then the synchronisation must be taken from this board position.

e.g.: If a system is equipped with one BTU-D to the public exchange, another BTU-D where a sub-system is connected and an ICCU, the digital trunk line to the public exchange must be chosen as highest priority link and ICCU as second priority.

The second BTU-D (tie line traffic) is the MASTER for the sub-system. Five different priorities are possible.

Valid values: Trunk card, ICCU card, MFU card. The submitted value consists of 5 digits. The first two give the card position (01 for card 1, …) the last 3 are set to “000”.

Minimum required authority level from telephone: No

Accessible via BMS: Yes
