2.7. SIM Card Installation/Removal
Insert the SIM card into the SIM card slots with your hand
as shown in Fig. 7. Please make sure that the SIM card contact plates are on the
side closer to the GSM gateway antenna connectors. Having inserted the SIM
card, push the card gently until you hear a click signalling that the card has been
snapped
by the push/pull holders. Secure the SIM card by shifting the latch to the right in
order to avoid incidental removal of the SIM card.
To remove the SIM card take the opposite steps. You can replace
a SIM card even with the gateway on.
Fig. 7 – SIM Card Inserting Procedure
In case of SIM card replace is necessary to make restart of GSM module or whole
gateway.
2.8. NT or TE Connection
ISDN terminals are connected to the NT and TE connectors depending on the
configuration of your telecommunication equipment. They are connected using a
4-wire passive bus through RJ-45 connectors. For NT or TE connections see Fig.
9
and
Fig. 10. The RJ-45 pins for TE and NT are shown in Fig. 8. Please keep in your
mind, that 2N
®
BRI Lite gateway has only one BRI ISDN interface. So you can
use only one RJ45 connector in one time (as NT or as TE according to
configuration)!
