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.

|---|---|
The number of ADSL StarModem which can be connected to the same USB 1.1 OHCI/UHCI controller is limited. Refer to Section 2.9.1.2, “Isochronous mode” to havo more information about isochronous mode. |

WARNINGS about isochronous mode:
USB 1.1 interfaces are handled with one OHCI/UHCI controller every 2 ports. Usually the ports that are close each other belongs to the same UHCI/OHCI controller;
USB 2.0 interfaces are handled with one EHCI controller for all the ports. In some rare cases, or when a PCI add on card is used, more EHCI controllers can be present;
isochronous mode reserves bandwidth on each USB controller. This means that the bandwidth is permanently robbed to other devices connected to the same controller;
the maximal theoretical USB bandwidth on USB 1.1. FULL SPEED is 12 Mbit/sec;
the maximal theoretical USB bandwidth on USB 2.0. HIGH SPEED is 480 Mbit/sec;
some bandwidth must be left free for interrupt and bulk transaction;
in Abilis CPX the maximal isochronous bandwidth limit for USB 1.1 is 9.6 Mbit/sec;
in Abilis CPX the maximal isochronous bandwidth limit for USB 2.0 is 384 Mbit/sec;
in Abilis CPX the isochronous bandwidth is dynamically reserved depending on the actual downstream (RX) speed, in 8 discrete step which are roughly 1,2,3,4,5,6,7,8 Mbit/sec.
As a result there is a limitation to the number of ADSL StarModem which you can connect to the same USB 1.1 OHCI/UHCI controller, as well as combination of StarModem with UMTS-BOX/BOX2, for example:
one StarModem at maximal speed and one UMTS-BOX/BOX2 are supported within a OHCI/UHCI controller;
two StarModem connected to 4 mbit/sec lines and one UMTS-BOX/BOX2 are also supported.
Adsl2+ modem is USB 2.0 device. Abilis accepts Adsl2+ connection to UHCI/OHCI (USB 1.1) only if there are not 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 add a limitation: it is not possible to use for Adsl2+ an additional USB 1.1 hub in presence of EHCI controller.

UMTS-BOX2 is a device which provides two independent interfaces to the GSM/UMTS mobile network. It can be connected to ABILIS router through an USB cable and supports full Voice, Data and SMS service.
The most important benefits of sim remotization are:
centralization of the SIM when a number of UMTS-BOX2 are dispersed in branch offices;
the management of sims is very malleable because the association between SIM and UMTS-BOX2 can be changed using software commands;
the association between SIM and UMTS-BOX2 can be changed by external applications that follow arbitrary customer rules.
The following steps are executed when connecting umtsbox2:
UMTS-BOX2 gets connected to abilis after 15 seconds when UMTS-BOX2/Abilis boots;
Once UMTS-BOX2 gets connected, the communication with Abilis starts after 5 seconds;
If Abilis doesn't drive UMTS-BOX2, UMTS-BOX2 waits 40 seconds and then resets itself. After the reset, the procedure starts from point #1.
If Abilis drives UMTS-BOX2 and the sim-container is inside the module and a sim isn't in the container, the module resets itself.

Power is provided both via USB to HUB, CODEC and PIC and with the additional power cable to SimCom modules. SimCom modules absorpt some current from the USB anyway, because of an internal -USB-powered- USB-to-serial converter interface chip.

The UMTSKEY device has been renamed CELLKEY because it now supports a 4G LTE dongle.
This device allows to exchange data and sms using an CELLKEY . It can be used as backup line when the main one fails, or to establish a connection toward Internet when calling an ISDN number (data call back).

RJS is an ISDN, ADSL or ethernet switch. It's equipped with:
one USB port
8 ports (each port includes 3 ISDN/ethernet ports)
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]](../images/note.png) | Note |
|---|---|
Only the central pins 4,5 and 3,6 are switched! Pins 1,2 and 7,8 are not connected. Refer to chapter Section 3.8.1, “Connection examples” to have more information about connection. |
There are two versions of RJS:
accepting only 5V power supply;
| Warning |
|---|---|
Connecting a power supply providing more than 5V-DC damages the device! |
accepting 12V power supply

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

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 is 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 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 a 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 of the cabinet, near the power main connectors.
