2.1Choosing a COTS Fax
By the nature of their design, Secure Telephones require operator intervention to place and receive calls and transition those call into and out of Secure Voice, Secure Data and Clear Voice modes. It is for this reason that we recommend that you choose one of the more basic COTS faxes to connect to your 90si. All of the COTS faxes automated features will not function in the Secure environment.
If possible, choose a COTS fax with a Hook, Monitor or
Memory Issues:
Additionally, static or permanent memory can be an issue when handling classified document. Gateway Fax Systems offers COTS faxes that have only dynamic memory, the contents of which is erased when the power is removed. Contact us if you wish to acquire one of these specially modified COTS faxes. And, as always, the 90si never retains any facsimile image data as it constantly overwrites image memory. Additionally, the memory chips used in the 90si are volatile. You may be doubly certain that no classified data remains in the 90si by depressing the Reset button, as image memory is also overwritten during the reset process.
2.2Choose a Location
Pick a spot that is within five (5) feet of your COTS fax, secure telephone or crypto, telephone line connection(s) and an AC power outlet. We recommend that you place the COTS fax on the left and your Secure Telephone on the right with the 90si in between the two.
2.3Choose a Configuration
The 90si's primary function is to allow your COTS fax to become a secure fax. The simplest (and recommended) configuration is called the Secure Only. If you choose, however, your 90si based secure fax system can also be used to send and receive unclassified fax messages; See section 2.3.2 Dual Mode Considerations.
