Fixed cellular terminal FCT ERICSSON 251 FAX (REFURBISHED)
ERICSSON F251m (completed production) (REFURBISHED) Ericsson F251m SOHO outwardly resembles its predecessor F151s but its functionality has been extended with a built-use data and fax. This enables data transmission standards GPRS and HSCSD as well as data transmission via the built-in analog modem V90. F251m also allows you to send SMS. The device accommodates a battery that provides work F251m case of power failure. The device is attached to the city's port analog telephone subscriber by allowing direct connection to the GSM network apart from the cost of fixed-line operator. For the device, you can also attach up to three analog telephony devices as analog phone, fax machine or fax modem. Using ISDN adapter, you can connect two devices F251m to port ISDN 2B + D PBX. There are different adaptations F251m eg. Remote wireless monitoring of premises (using cameras), remote transmission of alarm or provide the full range of telecommunications in areas that do not have fixed-line telecommunications infrastructure - voice, fax, data transmission, Internet. An important feature of F251m is signaling the start and end calls by reversing the polarity. This property allows precise connection time and so accurate pricing in the PBX.

Dimensions: height 148 mm, width 165 mm, depth 45 mm WEIGHT: 300 grams (without battery) Applications Fixed cellural Terminal (FCT) FCT enables rapid installation of phone line using digital cellular network infrastructure. Quick assembly / disassembly with minimum purchase and operation costs make a payback period of extremely short. Construction of a new line of access for the user is as simple as installing a new terminal FCT. By utilizing the FCT user you gain greater flexibility for users of mobile network planning and building their own private network. GSM operators provide competitive services, both in dense urban areas and remote rural areas. Applications Single Line Module The main part of the FCT is SLM (Single Line Module), which is a single linear module, which consists of a transceiver (transceiver), the line interface and the control unit. When the reserve power is not required, the SLM can be used independently, offering the same functionality as the FCT. SLM wall mounting or his work on the desk shortens start-up time and thus maximizing the return on investment. |
