Fractional T1 Line Configuration
The FaxPress Premier Fractional T1 unit will use the first 8 channels of the 24 channels
on a T1 line. Confirm with your T1 carrier that the T1 line they’re providing you has the
first 8 channels activated rather than the last 8 channels or the middle 8 channels.
Configuring the Premier Digital for a T1 with ISDN PRI Protocol
A T1 board configured to use ISDN rather than CAS protocol provides 23 fax channels. The
24th channel is used for data. Supporting a T1 with ISDN Signaling Protocol will require
you to:
1. Configure the Premier’s fax board to use ISDN protocol, according to the procedure
described in Configuring the Premier’s Board Settings for your T1 on page 18.
2. Disable channel 24 in the Premier’s Line Settings. See Configuring the FaxPress
Premier on page 102for details. The Premier will still display 24 channels in Fax-
Press Plus, but channel 24 will be disabled.
Note: For the FaxPress Premier to make international and domestic calls at the
same time, the T1 carrier’s central office switch must be configured to accept
calls where the CalledNumberType value is ’Unknown,’ rather than
’International’ or ’National.’ Most T1 carriers and lines support the ’Unknown’
CalledNumberType value, and use the DNIS dialstring value to determine if the
outgoing call is ’International’ or ’National.’Very rarely, however, some carriers
will configure the central office switch on their T1 PRI ISDN lines to accept only
’International’ or ’National’ CalledNumberType values, and so will not support
the ’Unknown’ CalledNumberType value of the FaxPress Premier’s Intel CPI/
2400CT-T1 board. When ordering T1 PRI ISDN lines, always make sure your
carrier’s central office switch will accept the FaxPress Premier board’s
’Unknown’ CalledNumberType value, or the FaxPress Premier will be unable to
make international and domestic calls at the same time.
Configuring the Premier’s Board Settings for your T1
The FaxPress Premier Digital’s default setting is T1 with Signaling Protocol CAS E&M, Line
Coding B8ZS, and Framing ESF. If your T1 line configuration matches the Premier’s default
configuration, you won’t need to change the Premier’s digital board configuration.
If your T1 line configuration is different from the Premier’s default configuration, however,
you will need to modify the FaxPress Premier’s digital board configuration. If, for example,
