Ricoh FAX5600L manual 232, Appendix C. Isdn G4 Option Type, Introduction, Batch Transmission

APPENDIX C. ISDN G4 OPTION TYPE 90

Introduction

The ISDN G4 Option Type 90 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 communication.

A few of the features described earlier in this manual 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, CSI (these identifiers can only be used with Group 3 communication. In Group 4 mode, another identifier called the Terminal ID is used instead; this is programmed by a service technician at installation. The Terminal ID is explained on page 240)

However, Group 4 has the following major advantages over Group 3:

❐If your organization sends large volumes of material by fax, using Group 4 will greatly reduce your communication costs as a result of the high speed of data transmission.

❐Normal analog networks tend to be noisy, affecting the quality of received data. However, communications over digital networks are of a high quality.

❐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 Networking section of this manual (see page 81).

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 page 124 for a description of the Batch Transmission feature.
