- Connect bits port 0 and 1 from the 7800-STM1 to the 1+1 patch panel.
- Connect bits port 0 and 1 from the 7800-STM1+1 to the 1+1 patch panel.
N+1 Configuration
The 7800 N+1 patch panels function as the bridge between the provider network and the TMG7800- STM1 gateways. To properly wire your gateways to the 7800 N+1 patch panel(s) to provide N+1 protection, follow these guidelines.
- Prepare a diagram that links each Tmedia unit serial number with an N+1 patch panel port and the network provider's STM1. This diagram will help for the web portal configuration later on.
- Relate the fiber optic cables from the network provider with each TMG7800-STM1 and use the same port number that is assigned to each TMG7800-STM1. See figure 4.9 on page 36
- If Automatic Protection Switching (APS) is used then repeat the EXACT SAME numbering scheme for each APS connection. For example, if a TMG7800-STM1 is assigned port number one on a 7800 N+1 patch panel that is being used for main connections, then the APS connections must also be assigned port number one on a 7800 N+1 patch panel that is being used for APS connections.
- Connect the TMG7800+1 unit to the N+1 port of the N+1 patch panel.
Connecting to the TMS Network
|
You must order one TelcoBridges CAT7 shielded Ethernet crossover cable, with RJ45 type male-male connectors, for each connection between 7800 Telecom units and a 7800-TMS. |
Connecting to the TMG7800 Telecom Units
The 7800-TMS enables you to scale your system by interfacing as many as sixteen 7800 Telecom Units with the 7800-TMS Switch network, building a non-blocking system of up to 32,768 channels. A second 7800-TMS provides your system with an active/standby high availability architecture.
Prerequisites
Use TelcoBridges CAT7 shielded Ethernet crossover cable to interconnect the 7800 Telecom Units with the 7800-TMS.
- Order one TelcoBridges CAT7 shielded Ethernet crossover cable, with RJ45 type male-male connectors, for each connection between 7800 Telecom units and a 7800-TMS.
- If your system features a second 7800-TMS, you must order an additional TelcoBridges CAT7 shielded Ethernet cable, with RJ45 male-male terminations, for each 7800 Telecom Unit.
Connections
To connect the 7800-TMS: 1. Start with the 7800 Telecom Unit at the topmost position of the equipment rack and connect a TelcoBridges CAT7 shielded Ethernet crossover cable to the TMS0 connector at the rear of the 7800 Telecom Unit. Connect the other end of the same TelcoBridges CAT7 cable to the first port of the first 7800-TMS.
|
Ensure that the TMS0 port of all the 7800 Telecom units connect to the same 7800-TMS switch. |
2. If your system employs a second 7800-TMS, connect a second TelcoBridges CAT7 shielded Ethernet crossover cable to TMS1 at the rear of the TMG7800 Telecom Unit. Connect the other end of the same TelcoBridges CAT7 cable to the first port of a second 7800-TMS.
|
Ensure that the TMS1 port of all the 7800 Telecom units connect to the same 7800-TMS switch. |
3. Repeat steps 1-2 for each 7800 Telecom Unit until they have all been connected to the 7800-TMS.
|
All telecom units must use the same TMS port number when two 7800-TMS units are available. |
Interconnecting Two 7800 Telecom Units
If your 7800 Series gateway has no more that two 7800 Telecom Units, they can be connected to each other without the use of a 7800-TMS switch, with two TelcoBridges CAT7 shielded Ethernet crossover cables. Simply connect the TMS0 ports of each unit together using a TelcoBridges CAT7 shielded cross-over cable, with RJ45 male-male terminations. Do the same for the TMS1 ports of each unit.

To access the 7800 Series Gateway, you must use an SSH connection. The password is set at the factory and is indicated on the shipment sheet.
7800 Series Gateway Serial Connection
Connecting to the 7800-CTRL Console
|
The default IP addresses for the management ports are located in the “Important Notice” sheet received with the shipment. MGMT ports are configured in bonding. |
You can connect to the serial port of a 7800-CTRL, using one of the following three methods.
Method 1: Null modem DB9 female-female cable
- Connect a null modem DB9 female-female cable between the DB9 serial port of your computer and the DB9 serial port of the 7800-CTRL.
Method 2: USB to DB9 adapter
- Connect the USB connector of the cable to a USB port on your computer and the DB9 male connector of the cable to one end of a null modem DB9 female-female cable. Connect the other end of the null modem DB9 female-female cable to the DB9 serial port of the 7800-CTRL.
Method 3: VGA Monitor, USB Keyboard, and USB Mouse
- Connect a VGA monitor to the VGA port of the 7800-CTRL. Connect a USB keyboard to an available USB port on the 7800-CTRL. Do the same for a USB mouse.
Configuring the Terminal Emulator Application
Before initiating communication with the management interface, you must first configure a terminal emulator or console application to communicate with the 7800 series system in order to configure initial settings. Available terminal emulation software includes:
- SecureCRT
- Putty
- Minicom
To configure the terminal emulator application:
1. Set the baud rate (bits per second) to 9600
2. Set the data rate to 8 bits
3. Set the parity to None
4. Set the stop bits to 1
5. Set the flow control to None
Changing the 7800 Series Gateway Management Port IP Address
The management port of the 7800 series gateway (MGMT0 and MGMT1) are configured in bonding by default and the values are located on the “Important Notice” sheet.
The values can be modified using the following shell script:
tbchangeip
|
|
If you do not have the “Important Notice” sheet, the default IP address and netmask are set as follows:
MGMT0
|
Retrieving 7800 Series Gateway Information
The 7800 series gateway enables you to retrieve system information with the following shell commands:
- tbinfo (retrieve the 7800 series gateway product type). See TMG:Get_Product_Type, for further information.
- tbserial (retrieve the 7800 series gateway serial number). See TMG:Get_Serial_Number, for further information.
Changing 7800 Series Gateway Management Port Passwords
Once logged you are logged on to the Tmedia VoIP Gateway, type “passwd”, to change the password being used. The following information will be displayed:
[root@TB003540 ~]# passwd
Changing password for user root.
New UNIX password:
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
Configuring the 7800 Series Gateway Using the Web Portal
Use the Web Portal to configure the 7800 series gateway. Follow the steps described in the Web Portal System Configuration Tutorial Guide, found on the TBWiki:
The Web Portal can be accessed with a Web browser. The default url is: http://[7800-ctrl MGMT0 IP address]:12358
The default login information to access the Web Portal application is:
- Username: root
- Password: root
System Backups
Creating a Database Backup
It is important that backups be made of system configuration settings in the event of a system failure. It is recommended that a backup be made once the system has been configured. Backups are performed
using the web portal.
Downloading a Database Backup
A backup of system data is stored on the hard drive of the 7800 series gateway. It is important that system backups be downloaded to an external storage device.
Uploading a Database Backup
An external backup of your database can be uploaded to your 7800 series gateway.
Restoring a Database Backup
In the event of a system failure requiring the replacement of a 7800 series gateway, a previously saved backup of system settings can be restored to the new unit.
