Introduction

The

Octel Overture 300 message server is a 32 to 128 port voice messaging system and the Octel

Overture 200 message server is a 4 to 64 port voice messaging system. When installed at a customer

’s

site, the message server attaches to the extension lines of a P

ABX or directly to the public network via

Direct Exchange Lines.

This document section describes certain operation requirements which must be complied with in the

United Kingdom to allow connection of the message server to a P

ABX or directly to the public network.

 

Failure to comply to the requirements described in this document may invalidate the

compliance of the apparatus, thus prohibiting its connection to the network in the United

Kingdom.

 

The approval of this apparatus will be invalidated if it is used with internal software not

formally accepted by BABT. The internal software is not accessible or alterable by the user.

 

There are no user serviceable parts, or user controls, in the system enclosure.

 

Interconnection directly, or by way of other apparatus, of Octel Overture 200 ports or

Octel Overture 300 ports with ports which do not comply with the requirements of BS6301

may produce hazardous conditions on the BT network. Advice should be obtained from

a competent engineer before such a connection is made.

 

When network addresses (telephone numbers) are manually entered into the system for

autoĆcalling, care should be exercised to ensure that the addresses are correct

 

This apparatus is not to be used for making calls to the BT emergency service.

Ringer Equivalence

Under

normal operating conditions, this apparatus is not meant to form part of a multiple installation; the

port interfaces are the sole termination of the line. Additional apparatus, BT or otherwise, must not be

connected between this equipment and the P

ABX line or public network.

Functions

The

Octel Overture 200 and the Octel Overture 300 message servers have the following functions.

-

Automatically answers calls redirected on no answer or busy conditions.

-

Interrogates the caller for any messages.

-

Stores the message.

-

Forwards the message as and when appropriate.

-

When connected to a PBX, the ability to answer and transfer a call.

-

The option to place outgoing calls (through a PBX, or directly into the public network) for the

purpose of delivering messages.

And the following outcalling functions.

-

The system operator can store predetermined numbers to be dialed for outcalls within the message

server

. These numbers include pauses to allow for secondary proceed indications.

-

The message server automatically schedules multiple call repeat attempts as required for

unsuccessful outcalls. The times between calls and the number of repeat attempts conform to the

requirements of the appropriate UK specifications.

-

The message server is suitable for connection to a P

ABX that returns secondary proceed indication

through the use of dialing pauses, as described above. For PABXs that do not return secondary

proceed indication, the pauses are not used.

Pay Phones

The

Octel Overture 200 and the Octel Overture 300 message servers are not suitable as an extension to a

pay phone.

Keys

When the message server is in operation, and is not being serviced by maintenance personnel, the key to

the enclosure shall be removed to prevent user (operator) access.

Outcall Configuration Requirements

The

Octel Overture 200 and the Octel Overture 300 message servers have the capability to outcall via the

P

ABX or directly to the public network via Direct Exchange Lines. The message server uses

multi-frequency dialing. Loop disconnect dialing is not supported.

" A
