3. KETS System Summary
KETS is an "omnibus" system, meaning that all the telephones are connected
in parallel on a single cable pair from the crossing to the concentrator.
In practice all the phones at a crossing are connected into a Line Termination
Unit (LTU), but this is a passive device containing only line conditioning
components, terminals to connect up to 4 devices to a common pair and an
ON OFF switch to isolate all crossing phones from the line. The ability for 4
telephones to work independently on a single pair with detailed fault
monitoring and without interfering with each other relies on each telephone
being an intelligent device with its own unique address on the system.
4. Addressing Procedure
To make sure that a KETS phone automatically acquires the correct address
the rules are simple:
1. Only apply power to a phone when the handset is OFF HOOK.
2. Always test ALL phones at a crossing before leaving site, even
if only a single unit has been changed.
These rules apply equally to a complete new crossing installation or
replacement of a unit or units on an existing installed crossing.
If a KETS phone powers up with the handset on hook, it will retain its previous
address. So, in the event of temporary disconnection or power interruption, all
phones will retain their original addresses and function normally.
When installing or replacing a phone, it is essential that it does not retain any
previously set address, for example from another crossing, which may cause
a conflict. Powering up with the handset off hook will force it to acquire a new,
unique address.
