PORTech's Range of GSM Gateways and GSM Fixed Wireless Terminals

Email Article

28 August 2007

PORTech provides GSM gateways, GSM fixed wireless terminals (one, four or eight ports), VoIP GSM gateways (one or two ports), E1 GSM channel BANKs, Skype GSM gateways, Skype gateways built into PCs (eliminating the need for an extra computer), and remote power switches by PSTN and the Internet.

GSM FIXED WIRELESS TERMINALS

MT-350, MT-354 and MT-358 one, four or eight port GSM fixed wireless terminals (FXS, FXO and GSM) provide a cost-saving effect: you can make calls from fixed lines (PBX or PSTN) to GSM networks and from GSM network to fixed lines. They also enable up to eight simultaneous calls to or from GSM networks.

Other advantages include:

FXS, FXO and GSM interface
Dial plan (GSM prefix number setting [50 sets])
Auto-select economic route (LCR)
Only one (MT-350 and MT-354) or two (MT-358) antennas
Polarity reversing function

There is also a 'follow me' call-transfer feature for both GSM to PSTN and PSTN to GSM. For PSTN to GSM an incoming call of PSTN will be transferred to a specific GSM number. For GSM in PSTN out, you hear a prompt "du" and can then enter any destination number, whilst an incoming call of GSM will be transferred to a specific PSTN number.

VOIP GSM GATEWAYS

We have two VoIP GSM gateway systems – the MV-370 one-channel VoIP GSM gateway, and the MV-372 two-channel VoIP GSM gateway – for call termination (VoIP to GSM) and origination (GSM to VoIP). It is SIP-based and compatible with Asterisk, SIP proxy servers and VoipBuster. It can make one to two calls simultaneously from IP phones to GSM networks and GSM network to IP phones.

DIGITAL MOBILE TRUNK: E1 GSM CHANNEL BANK

Our Digital Mobile Trunk (DMT) accepts incoming calls from the E1/T1 PRI of PSTN or PBX, and chooses one GSM channel to dial out according to the prefix of the destination mobile number. In this way, we can find the cheapest route.

DIGITAL MOBILE TRUNK ADVANTAGES

DMT can provide a Call Detail Record (CDR) for traffic and accounting management. Other advantages include:

ISDN PRI interface (one port)
GSM interface (31 ports)
Optional external SCE-900 – expands SIM card up to 32 pieces per GSM channel
Optional external SCBox – expands SIM card up to four pieces per GSM channel
Applicability for telecom service providers
VoIP application: the gateway's E1/T1 port connects to DMT's E1/T1 port
User assignment of the calling time for each sheet of the SIM cards: when the time runs out, system will block this GSM port, or switch to the next unused SIM card (in the case that a SCE/SC box is installed)
User choice of whether to hide the CLID of the GSM port or not
Auto-routing for the same network: the system will search for the GSM port of the same network to dial out, according to the prefix of the out-dialling number from the incoming E1 channel
ASR statistics: the system will provide a time-varying ASR-analysing report for easy understanding of the communication traffic
Two-way GSM to PRI

Additionally, we develop DMT-2 that is E1*1 in, GSM*31 and E1*1 out.

SKYTRUNK AND SKYSERVER GATEWAYS

Our range of SkyTrunk and SkyServer gateways includes:

SkyTrunk: Skype to PXB, PBX to Skype free
SkyTrunk ST-1004 – four-port Skype, FXO, FXS and GSM
SkyTrunk ST-2004 – four-port Skype and FXS
SkyTrunk ST-3004 – four-port Skype, FXO and FXS
SkyServer – four-port Skype and FXS (built into the PC, eliminating the need for an extra computer)

SMART POWER MONITOR

If your control room is unmanned, you can consider our smart power monitor. It can remotely turn power on and off, and reboot via PSTN or the Internet.
