APPENDIX C. ISDN OPTION TYPE 40

1. INTRODUCTION

The ISDN Option Type 40 allows you to send and receive fax messages on high- speed high-quality digital networks. It will allow you to connect the machine to an ISDN (Integrated Services Digital Network) for either Group 4 or Group 3 fax com - munication.

A few of the features described in the manual for your fax machine cannot be used over an ISDN. These are as follows.

Manual reception

Telephone line type (DTMF/Pulse dial) selection

Manual dialing with the handset

Voice Request

On Hook Dial

RTI, TTI, and CSI can only be used with Group 3 communication. In Group 4 mode, the Terminal ID is used instead.

However, the Group 4 interface will greatly enhance other features, especially broadcasting, transfer request, and other networking features, allowing complex distribution of documents with just a few keystrokes. The types of network that you can set up are described in the Facsimile Features Manual (section 5).

Note

Your sales or service representative will be able to help program all the necessary group and transfer station numbers in the various broadcasting terminals throughout your proposed network. Please coordinate with your sales representative to obtain correct programming at the time of installation.

Batch Transmission

The use of Batch Transmission is critical to making your Group 4 ISDN kit a cost effective alternative to Group 3. Set up a batch for each of your major fax message destinations. To do this, decide on separate times of execution for each of your batch files. Then, if you wish to send a message to one of these destinations, use Send Later to delay the transmission until the time that you decided for that destination. See the Facsimile Features Manual for a description of the Batch Transmission feature.
