PPP HDLC Fill – This value is the fill value to use on the data line across all slots when the data connection is
idle between HDLC frames. Typically the default value of all 1’s will suffice, but a flag fill may be desired in
AMI line mode.
Source IP Address
– This parameter is used to determine the static IP address for the Allworx server end of a
data connection. Typically, this is the public IP address associated with your ISP connection. If a value of
0.0.0.0 is entered, the service provider is expected to provide the correct value dynamically during session
establishment, if the service provider supports that. Consult your ISP for more information.
Destination IP Address
– This parameter is used to determine the static IP address associated with the
router/gateway at the far end of this Digital Line. A value of 0.0.0.0 can be used to have the service provider
assign the proper value, if the service supports that. Consult your ISP for more information.
Channel Assignments – On a Digital Line you must specify the desired operating mode for each time slot per
the provisioning defined by the service provider or the device you have connected at the other end of the
Digital Line. If the proper selections are not made, improper operation will result. Currently the following
modes are supported:
 Disabled
– Indicates that this time slot is not used on this Digital Line
 PRI B Channel
– A bearer channel for ISDN PRI operation that can be used for carrying voice calls.
Specifying this mode, in effect, defines a new outside line for the PBX for each slot configured in this
mode. A maximum of 23 slots can be configured for this mode.
 PRI D Channel
– A data-signaling channel for ISDN PRI operation, which is used for transporting call
control information between the PBX and the Central Office. The Allworx server always operates as
user equipment on a PRI line. If PRI operation is enabled on this line, exactly one slot must be
configured as the PRI D channel. Typically, this will be slot 24.
 T1 E and M Wink FG-B RBS
– A circuit switch Ear and Mouth mode Robbed Bit Signaling trunk with
Feature Group B signaling standards. Specifying this mode, in effect, defines a new outside line for the
PBX for each slot configured in this mode. This mode is symmetrical and can be used to hook PBX’s
back to back to tie PBX’s between sites on a leased line.
 T1 E and M Immediate Start RBS
– A circuit switched Ear and Mouth mode Robbed Bit Signaling trunk
that uses Immediate Start signaling. Specifying this mode, in effect, defines a new outside line for the
PBX for each slot configured in this mode. This mode is symmetrical and can be used to hook PBX’s
back to back to tie PBX’s between sites on a leased line.
 T1 FXO Loop-Start RBS
– A circuit switched Foreign Exchange Office style interface mode that digitally
emulates the standard analog telephone line interface that uses Loop-Start signaling. Specifying this
mode, in effect, defines a new outside line for the PBX for each slot configured in this mode. If call
volume is high, this mode is less desirable than FXO Ground-Start Operation. This is intended to
connect to the service provider interface that is operating as the FXS side of the interface. This mode is
NOT symmetrical.
 T1 FXO Ground-Start RBS
– A circuit switched Foreign Exchange Office style interface mode that
digitally emulates the standard analog telephone line interface using Ground-Start Signaling. Specifying
this mode, in effect, defines a new outside line for the PBX for each slot configured in this mode. The
Ground-Start operation is able to minimize the possibility of glare especially when call volumes are
high, making it more preferable than Loop-Start. This is intended to connect to the service provider
