To Make Connection
1. From File Menu, type d.
2. Highlight the customer from the customer list.
3. At the remote site, use the standard telephone (connected to the DKAdmin/DKBackup 
remote modem) to call a telephone (or attendant console) at the customer site.
4. When the call is answered, request that the call be transferred to the IMDU or RMDS by 
dialing 
Cnf/Trn + # 1 9; or, if using an external modem connected to the TTY port, by 
dialing 
Cnf/Trn + the external modem (RSTU) station number.
Important!The transferring party must hang up after transferring to the modem.
5. After the call is transferred and you hear modem tone from the IMDU, RMDS, or external 
modem, press F5, hang up the standard telephone when the DKAdmin/DKBackup PC 
modem goes off-hook. (The Modem String will be sent from the DKAdmin/DKBackup 
COM port.) The modems will handshake and connect, the After Connect String is sent to 
the Strata DK (if programmed).
NoteIf you press F4 in this step, DKAdmin/DKBackup will send the Modem Initialization 
String (from the Communications Setup Option) and then the Modem String (from the 
Customer File). If using a 28.8 fax/modem with you DKAdmin/DKBackup PC, it may 
be necessary to include &Q6 or &K0 in the Modem Initialization String to turn off data 
compression.
6. After the connection is established, select the desired function from the Administration 
Menu/Backup Menu and proceed.
7. After the DKAdmin/DKBackup session is completed, go to the File Menu and press h to 
hang up the connection. The DKAdmin/DKBackup PC sends +++ ATZ H to the 
DKAdmin/DKBackup PC modem, closing the communication link to the DK.
Important!
lWhen connected to an IMDU or RMDS modem, the Strata DK will drop the connection if 
an incorrect DK maintenance security code is entered during a DKAdmin/DKBackup 
backup session.
lYou may put the DK maintenance security code on the After Connect line in the Customer 
File setup. DKAdmin/DKBackup sends the DK security code automatically after the 
modem in the Strata DK and the DKAdmin/DKBackup modem establish connection. The 
data set in After Connect is sent after modem connection is established whenever F3, F4, 
or F5 is used.
lIf the DKAdmin/DKBackup PC/modem connects to the Strata DK modem but then 
DKAdmin/DKBackup closes the COM port immediately, perform the following steps and 
try again:
lMake sure DKAdmin/DKBackup modem baud rate is the same as the Strata DK 
modem baud rate.
lRun the ReIndex Files option from the DKAdmin/DKBackup Options/System Utilities 
Submenu.
lRemove the DK security code from the After Connect String.
