•Alternate number dialing

It is possible to assign two facsimile telephone numbers to one abbreviated dial number or one touch dial key (one as the primary telephone number and the other as an alternate telephone num- ber). The facsimile first dials the primary telephone number, then redials if the line is busy until the redialing limit count is reached. It will then begin to dial the alternate number. (Except for Relay/Mail- box/Confidential/Polling)

•Multi-address transmission function

Transmissions of the same original to multiple addresses (up to 375 addresses) are possible using one operation sequence, in which preset abbreviated dial numbers (300), and one touch dial keys (75) can be used. When the multi-key is specified, key pad dialing of up to 100 locations, is also pos- sible.

•Multi-polling reception

Polling receptions from multiple remote parties (up to 375 parties) are possible using one operation sequence, in which preset abbreviated dial numbers (300), and one touch dial keys (75) can be used. When the multi-key is specified, key pad dialing of up to 100 locations, is also possible.

•Relay transmission request function

The GD-1220/1221 can originate a relay transmission or serve as a relay station in relay transmis- sion transactions.

•Secure RX

Secure RX allows reception to memory to secure Originals during unattended periods. The user can select a specific time period and all day (24-hour) operation on selected days. The feature can be activated and deactivated by using a 4-digit security code.

•Memory transmission

Allows you to dial the remote party while scanning the original in memory. The original page data is cleared as the sending of each page is completed. Therefore, the memory is utilized effectively for transmissions. A maximum of 100 jobs of memory transmission are possible.

•Public fax box

An original can be reserved in image memory to be polled by remote stations multiple times. One of its merits is that any remote station (even one with a non-TOSHIBA facsimile) can poll such originals without a password.

•Program continuous polling

By designating the starting interval, time, and day-of-week, an endless polling can be set. Once set, polling receptions are repeated at the same time on the designated day-of-week.

•Sub-address communication

The GD-1220/1221 support communication applications using sub-address (SUB/SEP/PWD) com- mands conforming to ITU-T. Sub-address communication is possible by keypad dialing, one touch key dialing, and abbreviated dialing using the sub-address settings in Comm. Options.

•Security communication

For transmissions, the facsimile checks if the telephone number of the remote party’s facsimile CSI matches the number dialed on the unit itself. If it matches, the transmission will start. For receptions, the facsimile checks if the telephone number of the remote party’s TSI matches any number assigned to an abbreviated dial number or one touch key. If it matches, the reception will start. Thus transmissions or receptions with any authorized party will be prevented at the earliest stage.
