Adding a T1 Fax Board to the FaxPress Premier
T1 lines disconnected from an active device or loopback jack for more than 15 minutes will fail Central
Office loopback tests, and the Central Office will then cut off service. Typically the customer is charged
to restart the service. Make sure you use the loopback jacks as described below in step 1 to prevent this
from happening.
Each fax board added will increase the number of supported channels by 24 if the T1 sig-
naling protocol is CAS E&M, 23 if the T1 signaling protocol is ISDN PRI.
To install an additional T1 board in the FaxPress Premier Digital, follow these steps:
1. Disconnect the T1 line or lines from the FaxPress Premier, and plug one of the Cas-
telle-provided loopback jacks (shown below) into the connector at the end of each
disconnected T1 line. This will prevent the T1 carrier from cutting off service to the
T1 lines.
2. Discharge static electricity from yourself by touching a grounded surface, attach a
grounded static-dissipative wrist strap, and make sure the working sur-face is
static-dissipative and grounded.
3. Shut down the FaxPress Premier by accessing the System Information folder in the
System & Diagnostics folder. Right-click in the blank area of the list to the right
side of the Faxmain window, and choosing the System Shutdown command.
