20 Installation
21 Choosing 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 Manual-Dial button. This Hook button takes the fax
machine off-hook just as if you had lifted the handset of a phone. Whatever it may be called, using this button
to send a secure fax will cause the fax machine to enter what is usually called the "manual transmission" mode
whereby pages are scanned and sent one at a time. In this way you will know, at a glance from across the room,
the status of the transmission and when the transmission is complete.
Memory Issues:
Additionally, static or permanent memory can be an issue when handling classied 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 modied 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 classied data remains in the 90si by depressing
the Reset button, as image memory is also overwritten during the reset process.
22 Choose a Location
Pick a spot that is within ve (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3 Choose a Conguration
The 90si's primary function is to allow your COTS fax to become a secure fax. The simplest (and recommended)
conguration is called the Secure Only. If you choose, however, your 90si based secure fax system can also be
used to send and receive unclassied fax messages; See Section 2.3.2 Dual Mode Considerations.
