Steps to install the GSM Gateway in the network: 1) Connect the power cable with the GSM Gateway
- 2) Connect the network cable at FE0 PORT of the GSM Gateway 3) The default IP of gateway is 192.168.11.1
- 4) After your gateway is in your network then choose one laptop and add the IP of 192.168.11.100 or any 192.168.11.x Series in your laptop so that you can ping the gateway from that laptop.
- 5) Once you got the ping open the gateway in the browser by searching 192.168.11.1.
- 6) Default username and password of the gateway is admin respectively.
- 7) Change the IP Address of the Gateway from the quick setup wizard and give the IP according to the network.
- 8) Restart the gateway
Steps to upgrade the firmware:
1) Login the web management of the gateway, click “System Information” and check the firmware version.
2) Get the upgrade package from dinstar support
3) Upload the upgrade package. The upgrade package must match 0xxx or 2023xxx. For example, if the current firmware version is 02230703, the upgrade package must be 02230801.tar.gz, can’t be 02220801 or 01230801. We should always check the series of the firmware while uploading it.
4) click “Tools” and “Firmware upload”. Select the upgrade package and click “Upload”.
5) After successfully uploading the firmware, restart the gateway.
Answer : Steps to fix BCCH in the GSM Gateway:
1) Change the port’s BCCH mode to default and wait for the available frequencies listed.
2) Change the port’s BCCH mode to fix, and enter the available frequencies. Save.
3) Check the result.
Answer: If the GSM antennas are too close, when GSM modules work, the interference appears, and this, of course, affect the performances of Dinstar VoIP GSM Gateway DWG2000 series as bellows:
1. ASR is bad. Before each call, it is communication of SIMs’ data. As there is interference, the communication may fail or the efficiency may be low, then the call will fail or the time of setup a call will be long. Moreover, if GSM Base station is busy, other calls will occupy the station channels as the interference causes the communication efficiency is low on the gateway.
2. SMS/USSD sending is slow. The interference on the data communication will cause re-send or failure
3. Little influence on voice quality. If the call has setup successfully, users won’t feel obviously on the interference. Because the wrong codes on voice is not so serious on voice quality. So, we recommend
1. Place the antennas at locations where wireless signals are good.
2. As indicated in the picture, the space between antennas should be more than 12cm.
3. Place the antennas in the open areas. Eg Don’t place the antennas close to the big-size metal boxes.

Sangoma vega have 2 LAN, Port 1st port on DHCP & 2nd port default Static IP Address – 192.168.168.2,
Answer : A network switch is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device. It is a L2 and L3 devices also read MAC address.
Connect the power cable into AC power socket.
Connect an Ethernet cable into an outgoing port on your modem or router – sometimes marked as a
“WAN” port (on a router – any port will do)
- 1.Take the other end of the Ethernet cable and plug it into any port on your switch
- 2.Now plug another Ethernet cable cable into another port on your switch
- 3.Plug the other end of the Ethernet cable into your device
Answer : An Unmanaged Switch allows devices connected to a network (LAN) to communicate with each other. It is a plug-and-play switch.
Answer : “No” Configuration is not allow in this type of switch.
Answer : A managed switch provides the ability to configure, manage, and monitor your Local Area Network (LAN). This provides advanced features to control your LAN traffic. We can modify it according to our requirment.
•Spanning Tree Protocol support for switch and link redundancy without creating loops;
•the ability to implement quality of service;
•bandwidth rate limiting
Answer : “YES” A managed switch will act like an unmanaged switch essentially. (there is no config on it yet).
A layer 2 switch is a type of network switch or device that works on the data link layer (OSI Layer
2) and utilizes MAC Address to determine the path through where the frames are to be forwarded.
Layer 2 switch Can communicate within a network only.
A layer-3 switch can perform some or all of the functions normally performed by a router. Layer-3
switches typically support IP routing between VLANs configured on the switch. Some layer-3
switches support the routing protocols.
Layer 3 switch Can communicate within or outside network.
Answer : Layer 3 switch support protocols like STATIC, OSPF, EIGRP, RIP, BGP, MPLS.
Answer : “YES” we can use it as a router. If orgination work on any protcol like OSPF, EIGRP, RIP, BGP etc.
Answer : “NO” layer 3 switch is not support NAT. But some advance series support NAT.
The uplink port on switch is used to connect a device or smaller local network to a larger network.
The downlink port on switch is used to connect a device or local network.
Answer : The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for data communication applications. These small metal devices plug into a special switch slot and support communication over either fiber optic or copper networking cable.
Answer : In fact uplink port can serve as normal port. Therefore, there are no big differences between them. The only difference is that uplink port is connected to higher layer network device to aggregate the bandwidth and must be connected to the normal port on another network device.
Copper and fiber cable can be used in SFP module.
SFP = 1/2.5 GBPS
SFP+ = 10 GBPS
SFP28 = 25 GBPS
QSFP stands for 4 channels of SFP traffic. It stands for Quad (4-channel) Small Form-factor
Pluggable Optics Transceiver. It is a compact, hot-pluggable fiber optical transceiver used for 40
Gigabit Ethernet (40GbE) data communications applications.
4 x 1 Gbit/s QSFP = 1GE
4 x 10 Gbit/s QSFP+ = 10GE
4 x 28 Gbit/s QSFP+ (QSFP28) = 100GE
PoE is a revolutionary technology that allows network cable to provide both data and power for the
Non-PoE switch, just as the name, is the normal switch, which can only send data to network devices. There is no PoE in the normal switch to supply electrical power for end users over Ethernet.
1- General switch issue
- • check power connectivity.
- • check ethernet cable.
- • check switch port and RJ45 connector.
- • Connector should be tight in the port.
- • Power OFF and ON the switch.
2- vlan related issues
To create VLAN
[Huawei] system name Switch A
[Switch A] vlan batch 2 3
To assign interface to specific vlan:
Switch A] interfaceethernet 2/0/1
[Switch A-Ethernet2/0/1] port link-type access
[Switch A-Ethernet2/0/1] port default vlan 2
Switch A-Ethernet2/0/1] quit
3- Spanning-tree issues ?
To avoid loop in network
4- VLAN trunking issues.
