Bhumika introduces the latest T1 GSM Gateway with 72 SIMs (3 SIMs per each GSM channel - 72 SIMs per T1). Each GSM channel individual programmable to work with any of the 3 SIMs assigned to that GSM channel according to the "user" programmed time-table ("user" programmed time-of-day schedule). This enables the user to program a least-cost operation so that traffic, at any time-of-day, is only directed to the preferred SIM (out of the 3 SIM cards per GSM channel) - which shall activate only according to the "user" programmed time-table ("user programmed time-of-day schedule). The latest compact T1 GSM Gateway solution integrates the T1 interface to the GSM network to provide the user with 72, GSM links (72 SIMs) for mobile communications with an integrated T1 interface.

The T1 GSM Gateway / T1 GSM Channel Bank offers numerous applications for operators, which include 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.

Bhumika offers both E1 GSM Gateways and T1 GSM gateways / GSM channel banks with the following features:

• The interface of the network side is T1 Digital Interface.
• The interface on the user side is up to 24 x GSM links (72 SIMs per T1 - 3 SIM per channel).
• Accurate answer supervision and disconnect supervision. Each GSM channel individual programmable to work with any of the 3 SIMs, according to the user programmed time-of-day schedule. This enables the user to program a least-cost operation so that traffic of each GSM channel is directed to the preferred SIM (out of the 3 SIM cards per channel) - which shall be activated only according to the "user" programmed time-table ("user programmed time-of-day schedule).
• GSM Gateway to automatically "call" a "user" programmed number at a "user" programmed time-of-day, once every 24 hours to confirm to the operator that each GSM channel is in operation.
• Pre-Paid Balance Enquiry: GSM Gateway automatically enquire each PRE-PAID GSM SIM card for balance minutes / balance credits and sending an SMS message with this information to a "user" programmed number at a "user" programmed time-of-day.
• Mix 'n' Match 3 SIM per channel and 1 SIM per channel GSM access cards.
• Unique caller ID blocking feature (if network allows)
• Echo cancellation up to 128ms. provided - optional
• Remote access monitoring over TCP/IP network - optional
• Unique out-bound calling, user programmable, access feature.
• All 24, GSM channels are dual band - 900MHz and 1800MHz with auto-sense / auto-switching capability.
• All 24, GSM channels are dual band - 900MHz and 1900MHz with auto-sense / auto-switching capability.

Features and Highlights

• Compact, 24 GSM terminals (72 SIMs per T1) in a 19-inch chassis.
• GSM is integrated to the T1 Interface.
• Exceptional voice quality. The two wire trans-hybrid analog path (present in the Fixed Wireless Terminals) is eliminated in the innovative design, resulting in improved voice quality, clearer voice and superior channel separation by reducing the susceptibility to echoes that result from the analog two wire trans-hybrid VF paths.
• Provides accurate billing information ("answer supervision" and "line disconnect supervision") - not provided by Fixed Wireless Terminals.
• Integrated, optional, T1 Echo-Canceller to cancel echo tails from inherent delays of VoIP / VoFR networks - 64ms. uni-directional, 128ms. uni-directional and 64ms. bi-directional options available.
• Lower cost - resulting from complete, GSM to T1 integration.
• Plug-And-Play. Easy to install. Takes only minutes to install and start service.
