Public Switched Telephone Network (Pstn) Approval; Ren And Sen Numbers - ADEMCO Galaxy 16 Engineer's Manual

PSTN Approval
The Galaxy 16 plus has been approved for the use of the following facilities:
• Auto-dialling.
• Auto-answering.
• Auto-clearing.
• Modem communications.
• Series connection.
• Operation with Call Process Monitor (CPM) tone recognition.
• Multiple repeat attempts.
Any other usage invalidates the approval of the Galaxy 16 plus if, as a result, it
then ceases to comply with standards against which approval was granted.
Approval of the Galaxy 16 plus is also invalidated if it is used with internal
software or subjected to any hardware modification not authorised by BABT.

Public Switched Telephone Network (PSTN) Approval

The equipment has been approved to {Council Decision 98/482/EC} for Pan -
European single terminal connection to the Public Switched Telephone Network
(PSTN). However due to differences between the individual PSTNs provided in
different countries the approval does not, of itself, give an unconditional
assurance of successful operation on every PSTN network termination point.
In the event of problems contact the equipment supplier in the first instance.
The Galaxy is designed to interwork with the following networks:
Austria France
Belgium Greece
Denmark Iceland
Finland Ireland
Note: Contact the equipment supplier before using the Galaxy 16 plus on any
network.

REN and SEN Numbers

It is possible to simultaneously connect a number of items to one line of the
PSTN. The limit is determined by summing the Ringer Equivalence Number
(REN) shown on each item of apparatus, ensuring that the sum of RENs is not
more than four.
The REN of the Galaxy 16 plus is one (1).
Assume that all British Telecom equipment has a REN of one unless otherwise
marked.
