Ricoh FAX5600L - Manual (Page 246)

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.
