Product Overview
Bhumika introduces the latest E1 GSM Gateway with 90 SIMs (3 SIMs
per each GSM channel - 90 SIMs per E1). 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 E1 GSM Gateway solution integrates
the E1 interface to the GSM network to provide the user with 30, GSM links (90 SIMs) for
mobile communications with an integrated E1 interface.
The E1 GSM Gateway / E1 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 E1 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. To read more about

The interface of the network side is E1 digital interface.
The interface on the user side is 30 x GSM links.
Bhumika offers both E1 GSM Gateways and T1 GSM gateways
/ GSM channel banks with the following features:
- The interface of the network side is E1 Digital Interface
with CAS R2 digital signaling.
- The interface on the user side is up to 30 x GSM links (90
SIMs per E1 - 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)

- 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 - 900MHz and 1900MHz with
auto-sense / auto-switching capability.
Features and Highlights
- Compact, 30 GSM terminals (90 SIMs per E1) in a 19-inch
chassis.
- GSM is integrated to the E1 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, E1 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 E1 integration.
- Plug-And-Play. Easy to install. Takes only minutes to
install and start service.
