1.2.1 Safety Precaution
The Media Gateway has a solid chassis and sturdy modules to ensure a high degree of durability.Even so, you must take care when unpacking and installing the Media Gateway system. Rough
handling can damage some of the internal components.
The electronic components in the Media Gateway system can be damaged by Electro-Static
Discharge (ESD). ESD occurs when you do not properly ground yourself before touchingelectronic components. Because some components carry minute electrical currents, they can
become damaged by the amount of current conducted by the human body.
To guard against ESD, attach an ESD wrist strap with a 1 MΩ resistor to the ground post (or plug,
also known as the 'banana jack') on the lower left of the Media Gateway front panel.
Danger : Electro Static Discharge
If you do not wear an Electro-Static-Discharge (ESD) protective wrist
strap this can result in serious personal injure and/or damage to thechassis.
Wear an ESD protective wrist strap having a 1 MΩ resistor when you
install the chassis to the facility power, and every time you perform a
hot-swap. The banana jack is not insulated, so make sure to wear the ESDstrap, even with the grounding post secured on the chassis. Insert the wrist
strap into the banana jack on the front of the chassis at the lower left
corner. The protective strap is not included with the chassis. You canpurchase one at a local electronics supply store. See figure 2 to see where
to insert the strap.
Figure 2 ESD Wriststrap Insertion into the Chassis
1.2.2 Safe Work Areas
If you need to remove or hot swap the Media Gateway hardware, follow these precautions: Make sure the work area is clean and free of moisture
Use an ESD safe work area

http://slidepdf.com/reader/full/a7515-mg-quick-start-guide-21m 11/49
A7515 Media Gateway Quick Start Guide
Always wear an anti-static wrist strap with a 1 MΩ resistor to protect against ESD or
personal injure
Do not use screwdrivers or other sharp or pointed instruments when removing or installinghardware, unless otherwise instructed
Lay modules flat when they are not in the Media Gateway, or store them in a static-free bag
Make sure that the Media Gateways have a vertical offset if they are being installed inside-by-side racks.
By installing the Media Gateways with the recommended vertical offset, you ensure that sufficientambient air exists to cool the warm components. The shelf fans then exhaust the warm air. The
offset also ensures that intake fans of another Media Gateway do not draw in the warm and exhaustair from shelves in a neighboring rack.

2.1 Understanding the Media Gateway
The Media Gateway works in the data layer, accepting call data from the Public Switched
Telephone Network (PSTN) or an access switch. Simultaneously, the control and signaling data are
sent from PSTN or access switch to the softswitch. The softswitch acts as the Media GatewayController (MGC). It provides the control, signaling and routing functions, so that the entire
bandwidth of the Media Gateway is free to carry voice traffic. Figure 5 illustrates the Media
Gateway in a typical network.

A7515 Media Gateway Quick Start Guide
2.2 Understanding Megaco / 7515 Terminology
The softswitch acts as the MGC. The MGC communicates with the Media Gateway using the
H.248/Megaco protocol. The Megaco protocol and terminology used within this chapter are
explained in detail in RFC3015 document and its corrections. Below is a brief description of thebasic Megaco concepts.
Media Gateway A media gateway converts media given in one type of network to the
format required by another type of network.
Physical Termination A physical termination represents a physical entity and has a
semi-permanent existence. A Time Division Multiplex (TDM) channel
configured in a gateway is an example of a physical termination. Ephemeral Termination An ephemeral termination is a temporary entity created by means of an
Add command sent from the MGC to the media gateway.
Context A context is an association between two or more terminations.
Associating a TDM channel from PSTN with a Real-time Transport
Protocol (RTP) packet stream creates a context.
Figure 6 illustrates these basic concepts.

2.4.10 One Step Software System Upgrade
A7515 supports the online software upgrade, i.e., user can upgrade system software when
system is running, and the new version of software will be used when the board reboots. All thesoftware of system will be saved on the flash disk after them upgraded.
The one-step software upgrade procedure automates the upgrade process by exploding the new
PAK file and extracting the new runtime and BPF text file. The automatic upgrade halts if itencounters an error (for example, if the PAK file does not exist). If the upgrade does halt, you will
need to determine what caused the error.Check the system Syslog messages for any informationabout error conditions.
UI command:
Upgrade system {non-hitless| hitless} <pak-file>
Arguments Non-hitless is for un-redundancy upgrade, hitless is for redundancy upgrade.<pak-file> is the name of the PAK file. It can be on the remote server like
“172.24.200.21:newpak.pak” or on the local flash disk like “newpak.pak”.
You can copy file from a TFTP server to A7515 flash by issuing the following command
tftp get <rmt-file> [<lcl-file>] You can copy file from A7515 flash to TFTP server
tftp put <rmt-file> [<lcl-file>]

2.6 Synchronize both FSBs
For redundant FSB configuration chassis, the both FSBs need to be synchronized. Connect two
serial cables on the RTMs’ Craft port. Reboot FSB respectively by command “reboot self”.
When the board is booting, press any key to stop it, input “9”, then “Enter”, input “2”, then“Enter”.
Example Press any key to stop auto-boot...
3
[VxWorks Boot]: 9
[VxWorks Boot]: 2
BPF: using bpf file, pf1:bpf.aat
use this vxworks:pf1:vxworks.bcLoading file pf1:vxworks.bc ...
Follow the same steps on both FSBs, then check the synchronization status:
