For receiving the signal of mobile network the GSM card is equipped four RF connectors, one
for each GSM modules. This allows you to set external directional antennas, each targeted towards
the base station of a specific mobile carrier.
The mobile card features also four status indicators, one per each GSM module. The
indicators are green LEDs, located above the SIM cards slots. The significance of the LEDs is
detailed in chapter 2.5 – Status Monitoring.
Two versions of mobile cards are available from Topex :
-
the one used in the compact, basic version of VOXI, which has a single antenna
connector for all the GSM modules, since it uses an internal splitter/combiner;
-
the UAB4M type, which has no combiner, so it features one antenna connector for each
module, thus four RF connectors per card.
2.4.3 Other
Interfaces
The VoxiPLUS gateways come equipped either with 2E1 interfaces or with four interfaces type
ISDN BRI. The 2E1 interfaces is provided by PGVOIP card depending on its manufacturing
configuration, and the BRI interfaces are located on the GSM modules base card.
Note: The equipment is conceived to operate either with E1 interfaces or BRI interfaces; both
features cannot function at the same time.
In addition to these, VoxiPLUS equipments in 2U configuration may take in up to three plug-in
cards. You may choose additional GSM channels, or you can have FXO / FXS interfaces for analog
voice calls.
FXO / FSX ports are present as single SLIC daughterboards on a MPAI motherboard; each
SLIC is assigned to one port. The SLIC is mounted on the MPAI card (configurable universal card).
The maximum number of FXO / FXS ports is 8 (eight) for one MPAI plug-in card. Thus, depending on
the customer’s needs, one MPAI card may have up to eight FXO / FXS port, or both types in different
combinations.
