13.4.9 Allworx Port Expanders
The Allworx PX 6/2 Expander provides expansion of the system analog capability by
adding six (6) FXO and two (2) FXS ports to any Allworx server. The PX 6/2 Expander
features Plug ’n’ Play installation for locally connected units. Remote installation is
possible using an approach similar to installing remote Allworx phones. For detailed
installation instructions, see the Allworx PX 6/2 Expander Installation Guide.
To configure an installed Allworx PX 6/2, navigate to Network > Port Expanders. This
displays a list of all Allworx port expanders known to the Allworx server. A number of
Channel Assignments (con’t)
• 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 connects 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 interface that is operating as the FXS side of
the Ground-Start interface. This mode is NOT symmetrical.
• 56K Data Channel - Specifies that this slot provides 56Kbits/sec of
bandwidth for the Digital Line’s logical data connection. This mode is
typically only used if 64K clear channel service is not available. Only
use this mode for data connections when selecting AMI Line Code
mode.
• 64K Data Channel - Specifies that this slot provides 64Kbits/sec of
bandwidth for the Digital Line’s logical data connection. Use this when
clear channel data service is available. Do not select this mode if
selecting the Digital Line’s AMI Line Code mode.
Note:
Do not use Allworx Port Expanders with 6x12 servers.
