The T1 GSM Gateway integrates the WAN T1 interface to the GSM mobile communications network. The compact T1 GSM Gateway solution integrates the T1 interface to the GSM network to provide the user with 24, GSM links for mobile communications with an integrated T1 interface.

T1 GSM Gateway / T1 GSM Channel Bank offer a wide range of applications including terminating VoIP, VoATM, VoFR, VPN, DCME E1 / T1 traffic directly into the GSM network, connecting remote (distant) locations over GSM networks, providing rural connectivity over GSM networks, last mile connectivity over GSM networks, quick basic telephony provisioning, corporate business fixed to mobile / mobile to fixed, GSM connectivity for river boats, costal cruise ships, fixed network back-up via GSM, VPN connectivity between two corporate networks, mobile back-up solutions for corporate businesses with high security requirements, and many more applications.

The T1 GSM gateway also replaces the cumbersome fixed wireless terminals and provides accurate answer supervision and line disconnect supervision, plus a host of other advantages, which include fast connection times (very short PDD) and high ASR rates that compete with the industry's best.

Both T1 GSM / E1 GSM Gateways / GSM channel banks are offered.

• The interface of the network side is T1 Digital Interface.
• The interface on the user side is up to 24 x GSM links.
• Accurate answer supervision and disconnect supervision.
• Unique caller ID blocking feature (if network allows)
• Remote access monitoring over TCP/IP network - optional
• Unique out-bound calling, user programmable, access feature.
• All 30, GSM channels are dual band - 900MHz and 1800MHz with auto-sense / auto-switching capability.
• All 30, GSM channels are dual band - 850MHz and 1900MHz with auto-sense / auto-switching capability.

Our intelligent E1 Channel Bank, VCL-CB-INT™ provides Voice Activity Detection (VAD) activated "answer supervision" and "disconnect supervision" to connect VoIP, VoFR and VoATM networks to analog PSTN (POTS) lines that do not provide any type of answer supervision / battery reversal functions.

The interface to the analog PSTN (POTS*) lines have been ruggedized to provide complete protection against line card failures which occur from induced voltages from AC power lines and lightening strikes and difficult field conditions.

The intelligent E1 channel bank can be used for VoIP, VoFR and VoATM network communications that will terminate traffic directly to the analog PSTN lines. The channel bank solution provides a cost-effective platform to convert up to 30 dial-up, analog (PSTN) voice circuits to a digital E1 interface to connect to VoIP, VoFR and VoATM Gateways.

Our years of experience in providing telecom transmission solutions to customers worldwide, located in over 80 countries, has been build in to providing a cost-effective - yet an intelligent E1 channel bank solution.

The VCL-CB™ E1 Channel bank offers all types of analog interfaces including FXO, FXS and 2W/4W E&M interfaces, that may be required to connect to an E1 digital interface of a VoIP, VoFR and VoATM Gateway.

The E1 Channel Bank shall interface to the E1 port of any Server / Switch / VoIP Gateway / PBX using R2 CAS (R2 Digital) Signaling (R2 Channel Associated Signaling) as per ITU-T Q.421 / Q.422 recommendations, to connect up to 30 analog interfaces to an E1 port.

Introducing the intelligent E1 Channel Bank, VCL-CB-BR™ with compatibility to fixed wireless cellular terminals / GSM fixed wireless terminals / Telular fixed wireless cellular terminals with voice activity detection (VAD) activated "answer supervision" and "disconnect supervision" to connect VoIP (Voice over IP), Voice over Frame Relay and Voice over ATM servers to GSM fixed wireless networks.

The E1 Channel Bank - the VCL-CB-BR provides answer supervision / battery reversal / polarity reversal support. Available with FXO, FXS and 2W/4W E&M interfaces. It used in applications to deliver voice over an end-to-end E1 (radio / fiber / HDSL) links.

The interface to the analog PSTN (POTS*) lines have been ruggedized to provide complete protection against line card failures which occur from induced voltages from AC power lines and lightening strikes and difficult field conditions.

The VCL-CB-BR™ E1 Channel bank offers all types of analog interfaces including FXO, FXS and 2W/4W E&M interfaces, that may be required to deliver voice over an end-to-end E1 (radio / fiber / HDSL) links.

Our E1 channel bank is especially designed for VoIP (Voice over IP), Voice over Frame Relay and Voice over ATM, call-termination and long distance communications markets and operators who wish to terminate their long-distance traffic directly to the GSM fixed wireless terminals. The channel bank solution provides a cost-effective platform to connect to up to 30, GSM fixed wireless terminals to a digital E1 interface of VoIP (Voice over IP), Voice over Frame Relay and Voice over ATM Gateways.
