  • Next generation multiservice platform with integrated media processing engine, packet processing engine, HW encryption and storage module
  • Made for critical communication and security solutions
  • Embedded real time Linux operating system
  • Best of both worlds – supports a mix of IP and traditional services within the same node
  • Backward compatible
  • SIP interoperability with VoIP systems and equipment
  • Wide range of open interfaces
  • Superb audio quality in all environments
  • New services through Web i.e. remote programming

The AlphaCom E combines the best of the present advanced AlphaCom system with the latest IP, Linux and embedded networking technologies. When entering the IP world, no compromise has been made. The AlphaCom E provides the complete set of existing services, quality, reliability and security characteristics for which AlphaCom has always been recognized.

Some of the special features it brings into the IP domain are wideband (7 kHz) audio, a built-in firewall, integrated Web and SIP server, hardware encryption and low latency switching.

In addition to these important characteristics, a new set of innovative services has been introduced to improve cost efficiency, service capabilities and system operation.

The cabinet has room for installation of 7 circuit boards, one AMC-IP processor board and up to 6 feature boards. The exchange also includes a power board and a cooling fan.

Several exchanges can be interconnected on AlphaNet over IP, as well as traditional methods, both locally and worldwide. All communication and services are available throughout the entire network.

The AlphaCom E-series includes extended integration of different kinds of communication and alarm systems, access control, CCTV, public address, public telephones and a variety of features and solutions that can be added when desired. It is easy to interface to 3rd party systems to create special applications.

The new technology allows remote programming, logging and maintenance via AlphaPro, Syslog and standard web browsers.

The cabinet can be wall or shelf mounted or mounted in a 19” rack. It has room for installation of one AMC-IP processor board and up to 6 feature boards. The exchange also includes a power board and a cooling fan.

Connection to AlphaCom E7 backplane
  • All cables are terminated to connectors on the backplane.
  • The two-pair star wired intercom cables are connected using pluggable screw connectors.
  • Two RJ45 Ethernet terminals are used for IP LAN, WAN, internet and AlphaNet IP communication.
  • The serial ports with RS232 and RS422/485 interface are used for interface to equipment using these protocols.
  • The two NO switches on the RCI connectors can execute programmable functions.
  • The 12 RCO’s are connected to optional MRBD relay boards and can be programmed to execute functions such as door control.
  • Connector 5 and 6 on the first ASLT line board are enabled for program distribution. Additional programs can also be connected to individual ASLT ports via the interface board FBSAR, 6 programs per board. If line points 5 and/or 6 are to be used as subscriber line points, follow the procedure described in "Physical number 5 and 6 (AlphaCom E7)".
  • The exchange is normally powered from the mains via a 24 VAC transformer. The 6 A type 203 0010 260 can serve up to 24 extensions, while the 11 A type 203 0010 270 is needed for a full cabinet of 36 subscribers.
  • Battery backup power can be connected to the 24 VDC input plug.

Ground connection

As from fall 2007 the E7 cabinet is equipped with a jumper which makes it possible to isolate the system ground (0V) from the chassis.

Jumper AC/DC

The jumper makes it possible to get galvanic isolation between the cabinet and the internal ground (0 V). The jumper should normally be in the "DC" position, which connects the cabinet and 0 V together.

In some installations, for instance on ships, it is not allowed for the return signal current to float to the chassis. In these installations the jumper must be set in "AC" position.

  • Jumper DC: Galvanic connection between 0V and the cabinet
  • Jumper AC: Galvanic isolation between 0V and the cabinet

In order to isolate the 0V from chassis on previous versions of the E7 (and AlphaCom M) cabinet, one has to isolate the whole cabinet using plastic washers.

Ground screw

The ground screw is connected to the cabinet, regardless of the jumper setting, and is used to connect the cabinet to protective ground.
