Denphone has been offering Digium products and services to the Japan market since 2005 and in 2008 was appointed an official Registered Digium Reseller.

We offer Digium products because they give you - our customer - the following benefits:

The Digium products we most commonly sell through our webshop are Digital and Analog Interface Cards.

Analog Digium Interface Cards and Analog Telephony Devices

Since 2001, Digium® has designed, manufactured, and sold PC-based telephony cards for extending the functionality of Asterisk® to the Public Switched Telephone Network (PSTN).

Digium® analog cards were created for connecting analog telephones and analog POTS (Plain Old Telephone System) lines to the PSTN through a PC. With these cards, users can transport calls from POTS to POTS, POTS to PBX, or POTS to VoIP. Using one of our analog cards in concert with Digium's Asterisk® software, standard PC platforms, and the Linux® OS, one can create telephony solutions capable of satisfying the needs of business applications with industry-leading quality. Digium's analog cards utilize patent pending VoiceBus™ technology. VoiceBus technology allows these cards to use an industry standard, bus-mastering interface as found in millions of PCs worldwide. VoiceBus maximizes system compatibility and prevents system conflicts.

Digium TDM Interface Cards and Wildcard Bundles

We stock a wide range of Digium analog TDM interface cards and Wildcard bundles. These can be purchased online when needed and shipped, not just to Tokyo, but to any address in Japan.

Following is a list of the Digium TDM inteface cards and Wildcard bundles we stock:

Digium AEX804E 8 Port Analog Interface Card

The Digium AEX800 is a half-length PCI-Express 1.0-compliant, 8 port analog interface card. The AEX800 supports combinations of station and/or trunk/line modules for a total of eight (8) interfaces.

More information about the Digium AEX804E 8 Port Analog Interface Card can be found at our webshop: Digium AEX804E 8 Port Analog Interface Card.

VPMADT032 (Echo Cancellation Module for TDM/AEX cards)

For Asterisk users who connect to the PSTN, the most common type of echo is hybrid echo - the echo introduced by the impedance mismatch between 2-wire and 4-wire telephone circuits. To combat this, Digium introduced DSP-based echo cancellation modules for their multi-port T1/E1/J1 cards and the 24-port analog card.

More information about the VPMADT032 (Echo Cancellation Module for TDM/AEX cards) can be found at our webshop: VPMADT032 (Echo Cancellation Module for TDM/AEX cards).

Digium S Series FXS Modules

A Foreign eXchange Station, or FXS, is a telephone interface which provides battery power, sends dialtone, and generates ringing voltage. A standard telephone plugs into such an interface to receive telephone service. Strictly speaking, a telephone exchange is an example of an FXS, as is the telephone jack on the wall, though the term is rarely applied except in connection with foreign exchange service.

Digiums FXS modules allow legacy analog phones to be connected to more up-to-date VoIP systems.

We offer two Digium S Series FXS Modules - the S110M and the S400M.

Digium's S110M FXS module allows the TDM400P card or TDM800P card to terminate analog telephones. The S110M FXS module can be purchased from our webshop: S110M FXS module.

The S400M FXS module allows the TDM800P card or TDM2400P card to terminate four analog telephones per module.The S400M FXS module can be purchased from our webshop: S400M FXS module.

Digium X Series FXO Modules

In telecommunications, a Foreign Exchange Office, or FXO, is a telephone signaling interface that receives POTS, or "plain old telephone service". It generates the on-hook and off-hook indicators used to signal a loop closure at the FXS's end of the circuit. Analog telephone handsets, fax machines and (analogue) modems are FXO devices, though the term is rarely used except in connection with Foreign exchange service (FX).

FXO interfaces are also available for computers and networking equipment, to allow these to interact directly with POTS systems. These are commonly found in devices acting as gateways between Voice over Internet Protocol (VoIP) systems and the public switched telephone network (PSTN).

Digiums FXO modules allow up-to-date VoIP systems to be connected to legacy analog systems.

We offer two Digium S Series FXO Modules - the X100M and the X400M.

Digium's X100M FXO module allows the TDM400P card or TDM800P card to terminate analog telephone lines (POTS). The X100M FXO module can be purchased from our webshop: X100M FXO module.

The X400M FXO module allows the TDM800P card or TDM2400P card to terminate four analog telephone lines (POTS) per module.The X400M FXO module can be purchased from our webshop: X400M FXO module.

Digital Digium Interface Cards

Since 2001, Digium® has designed, manufactured, and sold PC-based telephony cards for extending the functionality of Asterisk® for TDM to VoIP gateways and voice processing. All Digium digital cards are RoHS compliant and manufactured in an ISO 9001:2001 certified facility in the United States. Each Digium card is backed by a five (5) year hardware warranty as well as our Exceptional Satisfaction Program (ESP).

Digium digital cards are high-performance, cost effective, digital telephony interfaces. Digium digital cards in the TE series support both E1 and T1 environments. The environments are selectable on a per-card or per-port basis. This feature enables signaling translation between E1 and T1 equipment, and allows inexpensive T1 channel banks to connect with E1 circuits. The bus-mastering TE cards improve I/O speed over slave-only architectures, resulting in reduced CPU usage and increased card density per server. The cards provide the power to interconnect traditional telephony systems (legacy PBX) with emerging Voice-over IP (VoIP) technologies.

The TE cards support industry standard telephony and data protocols, including Primary Rate ISDN (both N. American and Euro Standard) protocol families for voice, PPP, Cisco HDLC, and Frame Relay data modes. Both line-side and trunk-side interfaces are supported, as well as advanced call features. All Digium E1/T1 interface cards have a built-in CSU/DSU and may be connected directly to the E1/T1 physical interface.

The TE cards have been designed to be fully compatible with existing software applications. They are fully integrated with Digium's Asterisk® software. The open source drivers for these cards support an API for custom application development. With the combination of Digium hardware and Asterisk software, numerous telephony configurations are possible. From the traditional PBX to VoIP Gateways, Digium solutions are paving the way for a new generation of worldwide communications.
