Galaxy Expand - Local Gateway (Expansion Chassis) Configuration

Local Gateway (as an Expansion Chassis to Local UCx)

Multiple Galaxy Expand chassis can be configured at a single location to support all the telephony interfaces required for a particular customer deployment. Expansion is accomplished by interconnecting either the Ethernet ports or the USB ports, or both from the Switch Fabric Card on the main Galaxy Expand chassis to their corresponding ports on the extension chassis.

To extend the Galaxy Expand system to multiple chassis:

  1. If there will be Ethernet based Telephony Interface cards in the expansion system (DSM16, PRI, or FXS16 cards) then connect both either the Eth1 or Eth2 interface on the Switch Fabric card on one chassis to the Eth2 or Eth1 interface on the second chassis. This extends the ethernet network used on the chassis backplane from one chassis to the next using a standard Cat5 (or better) ethernet cable.
  2. If there will be DAHDI based Telephony Interface cards in the expansion system (FXO8 or FXS8 Cards), then connect either the USB1 or USB2 interface on the Switch Fabric card on one chassis to the USB2 or USB1 interface on the second chassis. This extends the USB Bus used on the chassis backplane from one chassis to the next using a standard USB-A to USB-B cable.

Configuration

Switch Fabric Card

There is no configuration required on the Switch Fabric Card.  The connected Ethernet and USB interfaces simply create extensions of the backplane between the multiple chassis.

Telephony Interface Cards

For details on how to configure the optional Telephony Interface Cards, refer to the following:

  1. DSM16 Card Configuration (Ethernet Enabled)
  2. PRI Card Configuration (Ethernet Enabled)
  3. FXS16 Card Configuration (Ethernet Enabled)
  4. FXS8 Card Configuration (DAHDI Enabled)
  5. FXO8 Card Configuration (DAHDI Enabled)
