The ADSL USB modem enables one or more ADSL connections (one for each modem) directly on the Abilis without installing any additional router. Up to 8 modems can be installed into the same Abilis.

	Warning
	The number of ADSL StarModem which can be connected to the same USB 1.1 OHCI/UHCI controller is limited. Refer to Section 2.10.1.2, “Isochronous mode” to have more information about isochronous mode.

	Note
	The Abilis 5800UB modem is supported starting from Abilis firmware version 7.0.

	Tip
	Interesting chapters: Section 3.5, “ADSL modem connection”; Chapter 12, ADSL modem; Section 74.7, “How to configure ADSL connections using USB modems”. .

ADSL2+ modem is a USB 2.0 device. Abilis accepts ADSL2+ connection to UHCI/OHCI (USB 1.1) only if there aren't EHCI (USB 2.0) controllers in the system, and in the other case the connection is rejected and device reset is attempted for two consecutive times. This protection has been introduced to impede an undesired and wrong reconnection and tries to recover it. The protection also adds a limitation: it isn't possible to use for ADSL2+ an additional USB 1.1 hub in the presence of EHCI controller.

	Note
	The Abilis ADSL2+ modem is supported starting from Abilis firmware version 7.5.

	Warning
	Don't connect the Ethernet and power supply ports. The modem is powered from the USB port.

Figure 2.53. UMTS-BOX2

UMTS-BOX2 is a device which provides two independent interfaces to the GSM/UMTS mobile network. It can be connected to ABILIS router through a USB cable and supports full Voice, Data and SMS service.

The most important benefits of SIM remotization are:

The following steps are executed when connecting umtsbox2:

	Note
	The UMTS-BOX2 is supported starting from Abilis firmware version 6.5.

	Tip
	Interesting chapters: Section 3.9, “UMTS-BOX connection”; Chapter 15, UMTS BOX.

The LTE-BOX allows to exchange Data, Voice and SMS using a CELLKEY driver. It can be used as backup line when the main one fails or as gateway for the Internet, or as SMS gateway, or GSM/UMTS gateway to make calls to mobile numbers, saving you money.

	Note
	The LTE-BOX is supported starting from Abilis firmware version 8.1.

RJS is an ISDN, ADSL or Ethernet switch. It's equipped with:

This device checks the keepalive, so if the master (Mx) doesn't reply to the keepalive signal, the link is assumed to be down and the line is switched to the backup device (Bx) until the link is up again.

RJS can handle up to 8 lines.

	Note
	Only the central pins 4,5 and 3,6 are switched! Pins 1,2 and 7,8 aren't connected. Refer to chapter Section 3.10.1, “Connection examples” to have more information about connection.

There are two versions of RJS:

	The RJ Switch is supported starting from Abilis firmware version 6.3.

2.10.6.2. Functional block scheme

The RJ Switch is equipped with a PIC microcontroller which controls 8 on-board switches using the control lines. It's installed on the board and it's able to switch each LINE port to the corresponding main port or backup port.

This board contains a watchdog which must be driven by the main Abilis via USB; when the main Abilis stops sending LIVE signals to the board, the PIC understands that the main Abilis is failing and switches the line to the backup Abilis. The board's switch core/watchdog is based on a Microchip PIC18F2450.

Figure 2.56. External UPS

Abilis UPS is available as stand-alone device or embedded in Abilis Base-D model.

When it's embedded it also offers a monitoring interface which is internally connected to a USB port and can be monitored through a specific software resource.

It's also possible to modify some parameters to better satisfy own needs.

The default behaviour is that a periodical sound is emitted during the battery operation and the system is shutdown when the battery level is low. When the main power returns after a battery low shutdown the system will not restart immediately, it will wait until the battery will be sufficiently charged to allow another safe shutdown.

The UPS provides an on/off pushbutton for a complete power on/off of the system, which includes a complete reset of the UPS too. The pushbutton is accessible through a small hole in the cabinet, near the power main connectors.

	Note
	The UPS is supported starting from Abilis firmware version 8.0.

	Tip
	Interesting chapter: Chapter 19, UPS.

The USB Ethernet is an external adapter that plugs into the USB port of Abilis, to provide an Ethernet port.

	Note
	The Ethernet cable should not exceed maximum length 35m.

	Note
	The USB Ethernet is supported starting from Abilis firmware version 7.7.

	Note
	The USB Ethernet supports VLANs starting from Abilis firmware version 8.4.1.
