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.
  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.

Incoming call on FXO interface

  1. 2N® SmartGate UMTS detects a ringing signal and immediately interconnects it to FXS interface – the phone starts to ring.
  2. The CLIP transmitting must provide connected PBX.
  3. If you hook off the phone the call is established.

Automatic Call ("BabyCall")

If the BabyCall function is enabled on FXS interface, a pre-programmed timeout is counted down after off-hook. If you don't start dialing within this timeout, 2N® SmartGate UMTS signals dialing end and starts to establish a call to the pre-programmed number using UMTS/GSM network automatically – from now 2N® SmartGate UMTS behaves as if a standard outgoing call to UMTS/GSM had been established. Any dialing during the BabyCall timeout cancels this function and a standard outgoing call can be made.

ME- Mobility Extension

ME function takes place during ringing on FXS interface if 2N® SmartGate UMTS is programmed as DialThru gateway.

Fill in telephone number for ME function and number of rings to ME function start on FXO routing table sheet.

  1. 2N® SmartGate UMTS detects a ringing signal and immediately interconnects it to FXS interface – the phone starts to ring.
  2. If there is no call connection before the pre-programmed number of rings, 2N® SmartGate UMTS simultaneously establishes call to UMTS/GSM network. Some timeout take place between UMTS/GSM call establishing start and ringing of mobile phone.
  3. As long as 2N® SmartGate UMTS detects ringing on FXO interface, connected analog and UMTS/GSM phones ring.
  4. You can receive the call on analog line as well as on your mobile phone.
  5. During call received on mobile phone you can send FLASH to PBX, for special PBX functions, by preprogrammed DTMF code.


If you want repeatedly temporarily disable and afterwards enable the ME function, fill in Password for ME activation/disabling. If password is filled in:

  1. Hook off the phone.
  2. For temporarily disabling the function dial the password and confirm by . For activation the function dial the password and confirm by .
  3. Hang up.

Tariff pulses 16 or 12 kHz

2N® SmartGate UMTS has tariff pulse transmitter on FXS interface. You can use tariff pulses for outgoing call pricing. 2N® SmartGate UMTS offer pseudotariff only – tariff metering doesn't correspond to real price of call, tariff pulses are transmitted according to programmed parameters and call duration. You must program specific parameters in FXS routing table to set tariff metering for different prefixes of dialed numbers. Tariff metering is transmitted only during calls to UMTS/GSM network. Connected PBX must provide the tariff metering during calls to FXO interface.

You can also program 2N® SmartGate UMTS to transmit tariff pulses as call connect/disconnect signaling if your PBX cannot receive telephone line polarity reversal signaling.

Gateway for extension line of PBX

Extension line of PBX is connected to FXO interface on SmartGate UMTS. FXS interface remains unconnected.

You have to program parameter "FXO call route to" for proper function on FXO interface. You can fill in some rows in FXO routing table to reject given calls, for automatic call routing etc. 

Fill in GSM routing table to route an incoming UMTS/GSM calls to FXO interface.

It is necessary to set up conditions for call-disconnect detection from PBX. If 2N® SmartGate UMTS detects busy tone or continuous tone from PBX, it disconnects the established UMTS/GSM call.

 

Outgoing call on FXO interface

  1. 2N® SmartGate UMTS detects a ringing signal from PBX and, if it is possible to establish UMTS/GSM call, it hooks off the line after preprogrammed number of rings. 2N® SmartGate UMTS transmits dial tone and green LED for line starts flashing.
  2. Dial the UMTS/GSM subscriber number using DTMF. 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 FXO 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, 2N® SmartGate UMTS hangs up.
  6. When the called subscriber answers the call, a call is established. The green Line LED is permanently on during the call.
  7. Hang up to terminate the call. PBX sends busy tone to SmartGate UMTS's subscriber line, 2N® SmartGate UMTS detects it and disconnects the UMTS/GSM call.

Incoming call from UMTS/GSM network

  1. The CLI is compared with filled rows of GSM routing table. The call is rejected, or routed to FXO interface – extension line of PBX according to the routing table.
  2. 2N® SmartGate UMTS hooks off the line. If there is filled in the "Dial in" parameter for given CLI, 2N® SmartGate UMTS dials it using DTMF.
  3. The UMTS/GSM subscriber hears the ringing tone from PBX if the automatic dial in function was applied, if not he hears dial tone from PBX and he can dial required extension himself.
  4. The call termination is the same as in case of outgoing call.

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.
