APPENDIX C. ISDN OPTION TYPE 40
1. INTRODUCTION
The ISDN Option Type 40 allows you to send and receive fax messages on high- speed
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.
