4.1 Voice function
Outgoing and incoming call establishing procedures is for illustration described for
analog phone connected to FXS interface and extension line of PBX connected to
FXO interface on SmartGate UMTS. In case of other equipment connection, please
check SmartGate UMTS’s function by connecting a phone.
Suppose that a SIM card has been inserted, the PIN code entered or not required,
the antenna connected and 2N® SmartGate UMTS registered to UMTS/GSM
network – the UMTS/GSM network LED is permanently on and you can hear the dial
tone upon line off-hook.
DialThru gateway
Extension line of PBX is connected to FXO interface and phone is connected to FXS
interface on SmartGate UMTS.
Outgoing call on FXS interface
1. Hook off the telephone, you can hear the dial tone and the Line LED starts
flashing.
2. Dial the required 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, routed to UMTS/GSM network or to FXO interface 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 Line LED
is permanently on during the call (Orange for calls to UMTS/GSM. Green-
Orange alternate for FXS-FXO calls).
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 GSM routing table. The call is rejected,
routed to FXS interface – connected phone, or to FXO interface according to the
routing table. Routing to FXO interface isn’t usually used in case of DialThru
gateway.
2. Ringing on FXS interface signals incoming call. The 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.
