GSM-Route BRI
Installation and User Guide
Mounting the GSM-Route BRI
1.
Neatly locate and mount the GSM-Route BRI
using the supplied fixing template.
2.
Open the cover by pushing the two clips in at
the bottom of the case.
3.
Connect the Safety Earth Ground.
4.
Connect Antennae(s) (see figure 1)
5.
Insert SIM cards into the SIM holders (see
figure 2)
6.
Power up the unit. When the power is
connected the amber LED 3 will be lit and the
unit will initialise.
•
When the GSM Module(s) are connecting
to a network its status LEDs 24 & 25 will
produce long flashes (600ms/600 ms
On/Off).
•
If the GSM module has no SIM card
inserted its status LEDs 24 or 25 will flash
‘SOS’ on its associated LED.
•
When a GSM module has logged onto a
network its status LEDs 24 & 25 will
produce short flashes (75ms/3s On/Off).
(refer to figure 3)
•
The signal strength on Module 1 is
displayed as LED 18 and Module 2 is LED
19. (refer to figure 3)
•
If the Basic Rate ISDN interface is
activated the status LEDs 20 & 21 will
produce short flashes (75ms/3s On/Off).
•
When the Terminal Equipment Interface is
activated the status LEDs 22 & 23 will
produce short flashes (75ms/3s On/Off).
Testing the GSM-Route BRI
Go off hook and access one of the trunks
connected to the BRI Route GSM and:
1.
Make an outgoing test call over module 1.
Once Connected the Red Status LED
corresponding to the channel being used will
come on. The Green Status LED for module 1
will come on showing that the call has been
routed correctly. A confidence tone will be
heard at this stage.
2.
Make an outgoing test call over module 2,
once connected the Red Status LED
corresponding to the channel being used will
come on. The Green Status LED for module 2
will come on showing that the call has been
routed correctly. A confidence tone will be
heard at this stage.
3.
Make an incoming call to each GSM module.
Installation Scenarios
There are four scenarios for installing the BRI
Route GSM depending on your specific scenario
A.
Installed from the TE port to the PBX. The
PBX handles the least cost routing of calls.
(refer figure A.). LEDs 22 & 23 should
blink red (refer figure 2.)
B.
Installed as scenario A, but only the ISDN
clock/sync is received from the ISDN
network to the NT port. In this setup voice
calls are NOT carried from the ISDN
network to the unit and usually the NTU on
the wall has two mirrored TE ports, one
going to the PBX and one going (Providing
clock) to the NT port on the BRI Route
GSM. (refer figure B.) Note: requires
setting to
Track Mode
, refer to setting
ISDN Synchronisation.
LEDs 22, 23
should blink red (refer figure 2.)
Note: When the GSM Route BRI is
functioning normally, and it detects that
there is no ISDN connection on the NT
port, it then uses an accurate internally
generated clock. This accurate clock
cannot be synchronised with any ISDN
connections if it is not connected to them.
When the GSM Route BRI is forced into
Track mode
, you can plug an ISDN “NT”
or S0 trunk connection into the NT port of
the GSM Route BRI. This will then use the
clock synchronisation from the ISDN NT
Network connection (ignoring the B and D
channel information).
