PCI adapters

ASTERISK PCI GSM CARD - Junghanns.NET uno/duo/quadGSM

This PCI card is available with either 1,2 or 4 GSM modules (Motorola). It fits into a standard PCI slot and offers up to 4 SMA connectors for antennas.
Multiple Junghanns.NET GSM PCI series cards can be interconnected over an external PCM bus. The card's active channel switching capability (to bridge voice channels on the card without latency and not using the host CPU) is also working over the external PCM bus (e.g. voice channels on different cards can be actively switched). The Junghanns.NET GSM PCI series cards can be connected to any other Junghanns.NET card to build a real TDM switched PBX.

Features

• 1, 2 or 4 GSM quadband channels
• 1 SIM card per GSM channel
• optional SIM expansion boards available (2 SIM per channel, swapable during operation)
• DIGITAL audio quality (noise suppression, echocancel)
• digital call setup (fast)
• DTMF detection
• GSM data connections
• GPRS data connections
• SMS RX/TX
• PCM bus connectors
• daisy chaining of max. 8 cards
• 4 dual-color LEDs (network state indicators)
• active channel switching (across multiple cards over the external PCM bus)
• suitable for 3.3 volts and 5.0 volts 32 bit PCI slots
• 4 mini antennas are included with the card

Expansion modules are available that allow to use 8 SIM cards for 4 GSM modules, so one can change the SIM card with the software. There is also a slot HOT plug SIM card holder available which makes changing the SIM cards possible without having to shut down the PBX.


Drivers are included in Bristuff as of version 0.2.0-RC8r / 0.3.0-PRE-1o . They require the bristuffed Zaptel and Asterisk and a separate libgsmat (something similar to libpri for GSM signalling).

GSM Module for PIKA WARP Appliance for Asterisk/FreePBX

For Asterisk® / FreePBX® developers requiring GSM connectivity for wireline replacement, Least Cost Routing (LCR), or SMS notification, PIKA now offers a GSM module for the WARP Appliance for Asterisk®. The GSM module provides two GSM channels/radios per module and uses two externally accessible SIM cards. The module can work in combination with other WARP Appliance expansion modules (FXO, FXS, BRI).

Applications & Benefits

• Cost savings with Least Cost Routing (LCR) - For calls between landline and GSM or between different GSM networks, which can be very expensive, the FreePBX dial plan can be configured with a prefix that, when dialed, will route calls placed from a SIP or analog telephone over a GSM trunk.
• Back-up - Should the landline network go down, GSM can be used as a cost-effective backup.
• Land Line Displacement - For wireless carriers looking to build incremental traffic on their networks by displacing traditional telephone company land lines, Warp with GSM trunk connectivity provides a unique small/medium business telephone system option.
• Remote and Temporary Installations – Warp with GSM is an excellent option for the installation of business telephone systems in remote areas where traditional, wired telephone lines may not be available, or may have extended installation intervals. It can also be a great option for temporary installations.
• Increased productivity with SMS voicemail notification - No longer does a user need to continually check voicemail for that important message. Upon receipt of a voicemail, the owner of the mailbox can receive an SMS message that he or she has a new voicemail.

Features

• Two quad-band GSM channels/radios per module
• support for 2 SIM cards - externally accessible
• two modules per WARP
• GSM module can be combined with analog trunks (FXO), analog stations (FXS) or BRI trunks
• no external power supply required
• average power consumption = 1W per module
• 3V, 1.8V SIMs supported
• supports incoming and outgoing voice calls for PBX, Auto Attendant, IVR and other telephony applications

ICS France

ISDN PRI/SS7/VoIP/GSM channel bank, all in one designed

PowerGate GSM Channel Bank

ICS PowerGate Series Digital PRI ISDN Cellular VoIP Gateway comes with 2 ISDN PRI interface(In and Stack up), 16 GSM channels and 16 VoIP Channels. As ICS PowerGate cellular gateway has been enhanced with a VoIP interface, there is no need to install an external VoIP gateway.

PowerGate Series Digital Cellular gateway is easy to used for convert the full capacity of PRI ISDN directly into Cellular networks. The ICS PowerGate Series cellular gateway enables inbound and outbound traffic for both VoIP, PSTN, and GSM/CDMA calls. All in one designed, ideal gateway for terminating calls providing professional quality, stability and reliability.

IP<->GSM application with ICS PowerGate

ICS Universal Analog Cellular Gateway

ICS TopGSM Series Analog GSM Gateway comes with 1/4/8 ports and provides a cost- effective alternative for fixed-to-mobile telephone calls. They are compatible with any PBX system or analog phones.
opGSM Series GSM analog gateway is used for connecting with the FXO ports of an analog VoIP gateway. With the use of the TopGSM gateway, inbound VoIP calls destined for GSM handsets and calls originating from GSM handsets can be sent to or received from the GSM handsets by the VoIP gateway without having to route the calls through the local PSTN thus eliminating the cost of paying the local wireline telephone exchange for the unnecessary switching.
Up to 4 SIM Cards per GSM Channel
The 4 SIM cards feature of the TopGSM gateways is important in markets where there are more than one GSM operator providing GSM services. A common practice of a GSM operator is to offer special rate concession to its subscribers for calling Mobile Numbers that are within the same network of the GSM operator in various forms such as: one flat rate for calling any Mobile Number within the GSM network; or special discounted rates for calling Mobile Numbers that are within the GSM network.

Each TopGSM & TopCDMA Channel contains 4 SIM cards holders. An intelligent SIM card can be automatically switched according to 4 conditions:

Minute parameter --- You can change counting of outgoing calls.
         Count of minutes:  Gateway will counter time of outgoing calls.
         Count of calls: Gateway will counter number of outgoing calls.
By time --- SIM cards will be switched according to standby time
Time of use SIM ---- Interval of using selected SIM card.
Random --- SIM cards will be switched at random time.
             --- Interval of change SIM card. 
In this interval hours: minutes will be randomly switched SIM card. (SIM card will be switched after proceeding call hang-up).
