Chapter 2Quick Guide
This chapter is intended to help you grasp the basic operations of the SMG digital gateway in the
shortest time.
Step 1: Confirm that your packing box contains all the following things.
SMG Series Digital Gateway *1
Angle Bracket *2, Rubber Foot Pad *4, Screw for Angle Bracket *8
220V Power Cord *2
Warranty Card *1
Installation Manual *1
Step 2: Properly fix the SMG digital gateway.
If you do not need to place the gateway on the rack, simply fix the 4 rubber foot pads. Otherwise,
you should first fix the 2 angle brackets onto the chassis and then place the chassis on the rack.
Step 3: Connect the power cord.
Make sure the device is well grounded before you connect the power cord. Check if the power
socket has the ground wire. If it doesn’t, use the grounding stud on the rear panel of the device
(See Figure 1-3) for earthing.
Note: Each SMG digital gateway has two power interfaces to meet the requirement for power
supply hot backup. As long as you properly connect and turn on these two power keys, either
power supply can guarantee the normal operation of the gateway even if the other fails.
Step 4: Connect the network cable.
Step 5: Connect the E1/T1 trunk. Connect the E1/T1 interface of the digital gateway to that
of the remote device by E1/T1 trunk. After connection, check if the synchronization
indicator (green LED) is lit and keeps on, which indicates that the E1/T1 trunk is well
connected and the E1/T1 module is successfully synchronized.
For the 75Ω-unbalanced coaxial cable, in consideration of various line conditions, each PCM on
the digital gateway is equipped with two grounding jumpers which respectively control the
grounding of the transmitting and the receiving end. Under normal condition, that is, the chassis of
the gateway is well grounded, the grounding jumpers at the receiving end should be disconnected
and the ones at the transmitting end should be short-circuited. This configuration is the factory
default setting and applicable in most situations so that there is usually no need to change it. For
the 120Ω-balanced twisted pair cable, the grounding jumpers at both ends should be
disconnected.
You can construct an E1 trunk according to Figure 2-1. Prevent reverse connection of the
transmitting and receiving lines. The state of the receiving line can be checked by the
synchronization indicator (green LED) of the E1 interface. When the receiving line is in a normal
state, the indicator is lit and keeps on. If the indicator is off or flashing, it means that the
connection of the receiving line may probably be reversed. However, the state of the transmitting
line can only be examined by the opposite terminal. The synchronization indicator starts working
only after the device is powered on and successfully initialized.

Step 10: Check the PSTN status.
After the configuration of signaling protocols, you can check the status of the PSTN trunks via
‘Operation Info PSTN Status’. Refer to 3.2.2 PSTN Status for detailed introductions. When
Time Slot 0 shows ‘Frame Synchronized’, the signaling time slot is in the state of ‘Signaling
Channel’ and all the other channels are ‘Idle’, it indicates the PCM is well configured. If Time Slot
0 or the signaling time slot shows ‘Faulty’ or the other channels are in the state of ‘Unavailable’,
there may be errors in the signaling protocol configurations and we suggest you return to Step 9
for check.
Step 11: Set routing rules for calls.
Note: For your easy understanding and manipulation, all examples given in this step do not
involve registration.
Situation 1: IP PSTN
Step 1: Configure the IP address of the remote SIP terminal which can establish conversations
with the gateway so that the calls from other terminals will be ignored. Refer to ‘SIP
Settings SIP Trunk’ for detailed instructions. Fill in ‘Remote IP’ and ‘Remote Port’ with
the IP address and port of the remote SIP terminal which will initiate calls to the gateway.
You may use the default values for the other configuration items.
Example: Provided the IP address of the remote SIP terminal is 192.168.0.111 and the
port is 5060. Add SIP Trunk 0; set Remote IP to 192.168.0.111 and Remote Port to
5060.
Step 2: Add the IP address of the remote SIP terminal configured in Step 1 into the
corresponding SIP trunk group. Refer to ‘SIP Settings SIP Trunk Group’ for detailed
instructions. Select the SIP trunk configured in Step 1 as ‘SIP Trunks’. You may use the
default values for the other configuration items.
Example: Add SIP Trunk Group 0. Check the checkbox before 0for SIP Trunks and
keep the default values for the other configuration items.
Step 3: Add PCM into the corresponding PCM Group. Refer to ‘PCM Settings PCM Trunk
Group’ for detailed instructions. Select the PCM used for call conversation as ‘PCM’. You
may use the default values for the other configuration items.
Example: Provided the PCM used for call conversation is PCM[1]. Add PCM Trunk
Group 0, check the checkbox before PCM[1] and keep the default values for the other
configuration items.
Step 4: Add routing rules. Refer to ‘Route Settings IPPSTN’ for detailed instructions. Select
the SIP trunk group set in Step 2 as ‘Call Initiator’ and the PCM trunk group set in Step 3
as ‘Call Destination’. You may use the default values for the other configuration items.
Example: Select SIP Trunk Group[0] as Call Initiator and PCM Trunk Group[0] as
Call Destination. Keep the default values for the other configuration items.
Step 5: Initiate a call from the SIP terminal configured in Step 1 to the IP address and port of the
SMG digital gateway. Thus you can establish a call conversation via PCM[1] with the
PSTN terminal. (Note: The format used for calling an IP address via SIP trunk is as
follows: username@IP address, in which, ‘username’ is a called party number which
conforms to the number-receiving rule of the remote device.)
Example: Provided the IP address of the SMG digital gateway is 192.168.0.101 and the
port is 5060. Provided 123 is a number which conforms to the number receiving rule of
the remote device. Initiate a call from SIP terminal 0 to the IP address 192.168.0.101 (in
the format: [email protected]) and you can establish a call conversation via PCM[1] to

Synway Information Engineering Co., Ltd
SMG Series Digital Gateway User Manual (Version 1.6.5) Page 10
the number 123.
Situation 2: PSTN IP
Step 1: Configure the called party numbers which are received from PSTN and will be processed
by the gateway. Refer to ‘Advanced Settings Number-receiving Rule’ for detailed
instructions. Enter either a particular number or a string of ‘x’s to represent several
random numbers. For example, ‘xxx’ denotes 3 random numbers. You may use the
default value for ‘Index’.
Example: Set Index to 99 and configure Dial Rule to 123.
Step 2: Set the IP address of the SIP terminal to be called by the gateway. Refer to ‘SIP Settings
SIP Trunk’ for detailed instructions. Fill in ‘Remote IP’ and ‘Remote Port’ with the IP
address and port of the SIP trunk. You may use the default values for the other
configuration items.
Example: Provided the IP address of the SIP trunk to be called is 192.168.0.111 and the
port is 5060. Add SIP Trunk 0; set Remote IP to 192.168.0.111 and Remote Port to
5060.
Step 3: Add the IP address of the remote SIP terminal configured in Step 2 into the
corresponding SIP trunk group. Refer to ‘SIP Settings SIP Trunk Group’ for detailed
instructions. Select the SIP trunk configured in Step 2 as ‘SIP Trunks’. You may use the
default values for the other configuration items.
Example: Add SIP Trunk Group 0. Check the checkbox before 0for SIP Trunks and
keep the default values for the other configuration items.
Step 4: Add PCM into the corresponding PCM Group. Refer to ‘PCM Settings PCM Trunk
Group’ for detailed instructions. Select the PCM used for call conversation as ‘PCM’. You
may use the default values for the other configuration items.
Example: Provided the PCM used for call conversation is PCM[1]. Add PCM Trunk
Group 0, check the checkbox before PCM[1] and keep the default values for the other
configuration items.
Step 5: Add routing rules. Refer to ‘Route Settings PSTNIP’ for detailed instructions. Select
the PCM trunk group set in Step 4 as ‘Call Initiator’ and the SIP trunk group set in Step 3
as ‘Call Destination’. You may use the default values for the other configuration items.
Example: Select PCM Trunk Group[0] as Call Initiator and SIP Trunk Group[0] as
Call Destination. Keep the default values for the other configuration items.
Step 6: Once PCM[1] receives a call from PSTN and the called party number conforms to the
number-receiving rules set in Step 1, it can establish a call conversation with the remote
SIP terminal via the gateway.
Example: Once PCM[1] receives a call from PSTN with the called party number 123, it
will route the call to SIP Trunk 0 of the gateway.
Special Instructions:
The chassis of the SMG digital gateway must be grounded for safety reasons, according
to standard industry requirements. A simple way is earthing with the third pin on the plug
or the grounding studs on the machine. No or improper grounding may cause instability
in operation as well as decrease in lightning resistance.
As the device will gradually heat up while being used, please maintain good ventilation to
prevent sudden failure, ensuring that the ventilation holes (see Figure 1-4) are never
jammed.
During runtime, if the alarm indicator lights up or flashes, it indicates that the device goes
abnormal. If you cannot figure out and solve the problem by yourself, please contact our
