E1 GSM Gateway
E1 GSM Channel Bank - 90 SIMs
The latest E1 GSM gateway (also available with PRI ISDN
[Euro ISDN] with 90 SIMs (3 SIMs per each GSM channel - 90 SIMs per E1) is a 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 PRI ISDN 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 connectitity 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 advantages of our integrated GSM
solution over the fixed wireless terminal solution at: Advantages

The interface of the network side is E1 digital interface. The interface on the user side
is 30 x GSM links.
Both the E1 GSM Gateways and T1 GSM gateways / GSM channel banks are offered:
- The interface of the network side is E1 Digital Interface with both, PRI ISDN (Euro
ISDN) and CAS R2 digital signaling.
- PRI ISDN (Euro ISDN) Q.931 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-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 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.
- Advantages over Fixed Wireless Terminals (PDF)
- 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.
