Chapter 2Quick Guide
This chapter is intended to help you grasp the basic operations of the SMG SDH gateway in the
shortest time.
Step 1: Confirm that your packing box contains all the following things.
SMG Series SDH Gateway *1
Rubber Foot Pad *6, Screw for Angle Bracket *8, Front Angle Plate *2, Back Angle Plate
*2, Earth Wire *1, Shielded Straight Through Cable *2
220V Power Cord *2
Warranty Card *1
Installation Manual *1
Step 2: Properly fix the SMG SDH gateway.
If you do not need to place the gateway on the rack, simply fix the 6 rubber foot pads. Otherwise,
you should first fix the front angle plates onto the chassis and then fix the chassis on the rack with
the help of the back angle plates.
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 SDH 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 optical fiber.
Step 6: Log in the gateway.
Enter the original IP address (LAN 1: 192.168.1.101 or LAN 2: 192.168.0.101) of the SMG SDH
gateway in the browser to go to the WEB interface. The original username and password of the
gateway are both ‘admin’. For detailed instructions about login, refer to System Login. We suggest
you change the initial username and password via ‘System Tools Change Password’on the
WEB interface as soon as possible after your first login. For detailed instructions about changing
the password, refer to Change Password. After changing the password, you are required to log in
again.
Step 7: Modify IP address of the gateway.
You can modify the IP address of the gateway via ‘System Tools Network’on the WEB interface
to put it within your company’s LAN. Refer to Network for detailed instructions about IP
modification. After changing the IP address, you shall log in the gateway again using your new IP
address.
Step8: Set PCM.
On your initial use of the SMG SDH gateway, you shall enter the PCM interface and set the
configuration items ‘Signaling Protocol’and ‘Interface’. These items must be in conformity with the
physical connection. You may use the default values of other configuration items. Refer to PCM
for detailed instructions about PCM Settings.
Note: You shall restart the service to validate the settings in this step. Refer to Restart for detailed
instructions.

different interfaces. See below for detailed instructions.
SS7-ISUP:
Note: For your easy understanding and manipulation, this step does not involve the ISUP
quasi-associated mode configuration. For descriptions about these configurations, refer
to SS7 Settings.
The configuration interfaces related to SS7-ISUP include: ISUP and SS7 Server.
On your initial use of the SMG SDH gateway, you may adopt the default values of the
configuration items on the ISUP interface. Note that the SS7 Server interface must be configured
properly. Otherwise, the PSTN trunks may be unavailable. Follow the instructions here to
configure the SS7 Server:
Step 1: Set OPC, Server IP and Signaling Point Code Standard. The OPC is generally allocated
by the central office. The Server IP is the IP address of the SS7 server and you may use
its default value. The Signaling Point Code Standard, which varies on the PBX model,
can be set to 24 or 14. After modification, click the ‘Modify’button on the right to save
the settings.
Step 2: Modify the current link or click the ‘Add New’button below the signaling link list to add a
new link. Enter the physical address of the actually used signaling PCM (E1 interface)

values for the other configuration items. After modification, click ‘Save’.
Step 5: Modify the current CIC routing rule or click the ‘Add New’button below the ISUP_CIC
routing rule list to add a new CIC routing rule. Select the DPC configured in Step 4 for
‘DPC’, fill in ‘CIC_PCM’according to the actual allocation and use the default values for
the other configuration items. After modification, click ‘Save’. Note that if multiple PCMs
in the gateway are used for voice transmission, they should be configured with multiple
CIC routing rules accordingly.
Note: After configuring SS7-ISUP related interfaces, you shall restart the service to validate the
settings. Refer to Restart for detailed instructions.
SS7-TUP:
Note: For your easy understanding and manipulation, this step does not involve the TUP
quasi-associated mode configuration. For descriptions about these configurations, refer
to SS7 Settings.
The configuration interfaces related to SS7-TUP include: TUP and SS7 Server.
On your initial use of the SMG SDH gateway, you may adopt the default value of the configuration
items on TUP interface. Note that the SS7 Server interface must be configured properly.
Otherwise, the PSTN trunks may be unavailable. Follow the instructions here to configure the SS7
Server:
Step 1: Set OPC, Server IP and Signaling Point Code Standard. The OPC is generally allocated
by the central office. The Server IP is the IP address of the SS7 server and you may use
its default value. The Signaling Point Code Standard, which varies on the PBX model,
can be set to 24 or 14. After modification, click the ‘Modify’button on the right to save

Synway Information Engineering Co., Ltd
SMG Series Digital Gateway User Manual (Version 2.0.0) Page 7
the settings.
Step 2: Modify the current link or click the ‘Add New’button below the signaling link list to add a
new link. Enter the physical address of the actually used signaling PCM (E1 interface)
and click ‘Save’to save the modification. If only one PCM is used for signaling in the

Step 3: Modify the current linkset or click the ‘Add New’button below the signaling linkset list to
add a new linkset. You shall select the link configured in Step 2 for ‘Link’and use the
default values for the other configuration items. After modification, click ‘Save’.
Step 4: Modify the current DPC or click the ‘Add New’button below the DPC list to add a new
DPC. Fill in ‘SP Code’with the signaling point code of the remote end (i.e. signaling
destination), select the linkset configured in Step 3 for ‘Linkset’and use the default
values for the other configuration items. After modification, click ‘Save’.
Step 5: Modify the current CIC routing rule or click the ‘Add New’button below the TUP_CIC
routing rule list to add a new CIC routing rule. Select the DPC configured in Step 4 for
‘DPC’, fill in ‘CIC_PCM’according to the actual allocation and use the default values for
the other configuration items. After modification, click ‘Save’. Note that if multiple PCMs
in the gateway are used for voice transmission, they should be configured with multiple
CIC routing rules accordingly.
Note: After configuring SS7-TUP related interfaces, you shall restart the service to validate the
settings. Refer to Restart for detailed instructions.
ISDN User Side/Network Side:
The configuration interface related to ISDN User Side/Network Side is ISDN. On your initial use of
the SMG SDH gateway, you may adopt the default value of the configuration items on this
interface.
Note: After configuring the ISDN interface, you shall restart the service to validate the settings.
Refer to Restart for detailed instructions.
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 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 Address’and ‘Remote
Port’with the IP address and port of the remote SIPterminal 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 Address 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 SDH 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 SDH 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].0.101) and you can establish a call conversation via PCM[1] to
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 Address’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 Address 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.

Synway Information Engineering Co., Ltd
SMG Series Digital Gateway User Manual (Version 2.0.0) Page 9
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.

The chassis of the SMG SDH gateway must be grounded for safety reasons, according
to standard industry requirements. Asimple 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
technicians for help. Otherwise it may lead to a drop in performance or unexpected
errors.

Note: The gateway provides the fuzzy search feature on this interface. After you click any
characters on Figure 3-2 and press the ‘F’button, the search box will emerge on the right top of
this page. Then you can input the key characters and the gateway will locate the channel on
which there is an ongoing call that conforms to the fuzzy search condition.
Take an example: As shown in Figure 3-3, after we input the character 100 to the search box, and
click the Search button, the gateway does a fuzzy search and locates that the ongoing call whose
CalledID contains the character 100 occurs on Channel 1 of Port 1.
