Gateway for trunk line of PBX
Outgoing and incoming call establishing procedures is for illustration described
for analog phone connected to FXS interface. The rules for call establishing in case
of trunk line connection are the same, you have to program your PBX to route
UMTS/GSM calls to SmartGate UMTS. We strongly recommend to check SmartGate
UMTS’s function by connecting a phone in case of interconnection with PBX trunk
line.
Outgoing call on FXS interface
1. Hook off the telephone, you can hear the dial tone and the orange Line LED
starts flashing.
2. Dial the required UMTS/GSM subscriber number. 2N® SmartGate UMTS
receives tone dialing (DTMF) by default. If your telephone transmits pulse
dialing only, program 2N® SmartGate UMTS to receive pulse dialing. The delay
between dialed digits may not exceed 5 s (programmable parameter). The number
is evaluated as complete after this timeout.
3. A short delay follows the last-dialed digit for 2N® SmartGate UMTS to await
further dialing. Then, the dialing end is signaled and connection is established.
4. Prefix of dialed number is compared with filled rows of FXS routing table. The
call is rejected, or routed to UMTS/GSM network according to the routing table.
5. If the called subscriber is available, you can hear the ringing tone. If not, you
can hear the busy tone or any of the UMTS/GSM provider’s messages.
6. When the called subscriber answers the call, a call is established. The orange
Line LED is permanently on during the call.
7. Hang up to terminate the call. The Line LED goes off. If the called subscriber
hangs up first, you can hear the busy tone.
Incoming call from UMTS/GSM network
1. The CLI is compared with filled rows of UMTS/GSM routing table. The call is
rejected, or routed to FXS interface – connected phone according to the routing
table.
2. Ringing on FXS interface signals incoming call. The orange Line LED flashes
during ringing. If programmed so, 2N® SmartGate UMTS transmits the CLIP by
FSK between the first and second rings. Advanced telephone sets are able to
display the CLI.
3. Hook off the phone to establish the call. The Line LED is permanently on during
the call.
4. Hang up to terminate the call. The Line LED goes off. If the called subscriber
hangs up first, you can hear the busy tone.
