5. 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. In case of other equipment connection, please check
SmartGate’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 SmartGate registered to GSM network – the GSM network
LED is permanently on and you can hear the dial tone upon line off-hook.
5.1. DialThru gateway
Extension line of PBX is connected to FXO interface and phone is connected to FXS
interface on SmartGate.
5.1.1. 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. SmartGate receives tone dialing (DTMF) by
default. If your telephone transmits pulse dialing only, program SmartGate 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 SmartGate 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 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 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 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.
5.1.2. Incoming call from 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, SmartGate 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.
