Access Node

Modular structure

The variety of board types available simplifies the process of expanding and upgrading the system, while our hardware solutions allow subscriber boards to be changed without interruption to service. PROTEI Access Node can be equipped with various interface boards in any combination depending on specific requirements.


PROTEI Access Node can function in circuit-switched and packet-switched modes, giving it tremendous potential for use in both traditional and NG networks.

Unified maintenance system

Maintenance of PROTEI Access Node can be carried out in different ways: Telnet/SSH, FTP, graphical web interface and command line interface.


PROTEI Access Node can be deployed in two ways:

  • As a separate unit installed in a rack on the operator’s premises.
  • As an autonomous unit in a vandal-proof casing with its own power supply and emergency notification system. Ideal for installation away from the operator’s premises, such as in a residential building.


Access Node from PROTEI provides the operator with a wide range of possibilities:

  • Internal switching capability
  • Call routing
  • Audio signal generation
  • Transmission/receipt of DTMF tones
  • Support for various types of ringing signals
  • Ability to set the remote side on hold
  • PRACK method support
  • Locating SIP servers support
  • Registration support


    The system supports the following interfaces: E1, PRI, Ethernet 10/100 Base-T, ADSL, ADSL2+, SHDSL, VDSL, PSTN, V5.1/2.

Signalling protocols

    PROTEI Access Node supports the following signalling protocols: DSS-1, R2, SIP, H.323, H.248/MEGACO, SS7
