The Galaxy Expand hardware platform is part of the E-MetroTel overall server portfolio. While it can function as a Call Server platform with a variety of Call Processor configuration options for standalone operation, it can also be configured in High Availability (HA) mode with an active/standby pair of call processors across two independent chassis units, as a Survivable Remote Gateway (SRG) system with a single processor, or even as a highly compact, large scale FXO, FXS, PRI, or Digital Station gateway with no Call Processors.
