CT505-30 LANforge-FIRE VoIP Call Generator

The CT505-30 supports SIP VOIP calls, including RTP data-stream generation. It can make 30 calls to itself (60 VoIP soft phones) per chassis. The CT505-30 is excellent for testing whether or not an existing infrastructure can handle increased VoIP call load, and can also be used to test SIP gateways and other infrastructure. The CT505-30 uses the MAC-VLAN feature to allow one virtual interface per phone, so each phone can use a unique IP address and use standard SIP protocol ports. Normal LANforge-FIRE traffic generation features (Ethernet, UDP, TCP, HTTP, etc) is also supported by the CT505-30 at no additional charge. The POLQA and PESQ automated quality scoring modules are included.

The CT505-30 1U rackmount chassis fits into a standard rack and is only 14 inches deep. It supports standard VGA, Keyboard, and Mouse interfaces for easy console/desktop access to the system. The rackmount chassis is relatively noisy, so it is better for a data center deployment than a desktop environment. Other form factors better suited for traveling or desktop use are also available at similar prices and performance. More powerful systems are also available and multiple LANforge systems can be clustered together into a single managed realm for increased call capacity. No additional hardware or software is required, but you may wish to manage the system using the LANforge-GUI on a separate machine.

Example Network Diagram

Quick Start Guide

1. Connect Management ethernet port to Management network or management PC. If connecting directly to a PC, an ethernet cross-over cable should be used. Or, connect VGA, Keyboard, and Mouse to the chassis and manage it locally.
2. Connect one or more traffic generating ports to the downstream side of the device under test. This usually is considered the 'client' side of the network.
3. Connect one or more traffic generating ports to the upstream side of the device under test.
4. Connect power plug to a standard US or European AC power source.
5. If managing remotely, install the LANforge-GUI on a separate management PC or Laptop. Windows and Linux GUIs are supported: Select the correct one from the CDROM or Candela Technologies Download page and install it.
6. The CT505-30 should now boot. If DHCP is enabled on the Management network, the CT505-30 will automatically acquire an IP address. If DHCP is not available, the IP address will be set to 192.168.1.101 by the LANforge scripts.
7. Start the LANforge-GUI on the management PC, or the CT505-30 console if managing locally, and click the 'Discover' button. It should find the CT505-30 appliance and add the IP address to the drop-down box in the Connect widget. Press 'Connect' and you will be connected to the CT505-30.
8. Select the Layer 3, Layer 4 and other LANforge-FIRE related tabs in the GUI to see existing traffic connections and to modify them or add new ones. You can also view a real-time report of the test with the 'Display' button for some traffic types.
9. LANforge can send Layer 3 traffic types between any two physical ports, so one can send traffic between port eth0 and eth1, eth0 and eth2, eth3 and eth4, etc. Use the Port Mgr tab in the GUI to configure the IP addresses for the interfaces as appropriate for your network and cabling.
10. Any modifications take place immediately after you click 'Submit'.

Software Features

LANforge VoIP/RTP Call Generator Feature Highlights.

1. SIP protocol used for call management.
   1. SIP over UDP is supported on both Windows and Linux.
   2. Can use directed mode, where VoIP phones call directly to themselves.
   3. Can also use Gateway mode where the VoIP phones register with a SIP gateway.
   4. SIP authentication is supported.
2. RTP protocol used for streaming media transport, and supports the following CODECS. More codecs may be supported in the future.
   1. G.711u: 64 kbps data stream, 50 packets per second.
   2. Speex: 16 kbps data stream, 50 packets per second, www.speex.org (Linux ONLY).
   3. G.726-16: 16 kbps data stream, 50 packets per second.
   4. G.726-24: 24 kbps data stream, 50 packets per second.
   5. G.726-32: 32 kbps data stream, 50 packets per second.
   6. G.726-40: 40 kbps data stream, 50 packets per second.
   7. G.729a: 8 kbps data stream, 50 packets per second.
   8. NONE: A messaging-only configuration is supported.
3. Supports POLQA and PESQ automated voice quality testing.
4. RTCP protocol used for streaming media statistics (SIP only).
5. Each LANforge VoIP/RTP endpoint can play from a wav file and record to a separate wav file. Almost any sound file can be converted to the correct wav file format with tools bundled with LANforge. Sample voice files are included.
6. Current benchmarks show support for 280 or more emulated VoIP phones per high-end machine.
7. LANforge VoIP/RTP endpoints can call other LANforge endpoints or third party SIP phones like Cisco and Grandstream. Third party phones can also call LANforge endpoints and hear the WAV file being played.
