User Guide V2IU 6400-S Converged Network Appliance • Remote system logging. • VoIP and subnet routing. • Firewall • Administration, maintenance and upgrading. The following chapters give you detailed processing steps you need to set up the 6400-S.
2 Installing the 6400-S Physical Installation1 Anchor the equipment rack that will contain the 6400. The equipment rack must be anchored to an unmovable support to prevent it from falling over when one or more systems are extended in front of the rack on slides. You must also consider the weight of any other device installed in the rack. A crush hazard exists should the rack tilt forward which could cause serious injury.
User Guide V2IU 6400-S Converged Network Appliance Overcurrent protection The 6400-S is designed for an AC line voltage source with up to 20 amperes of overcurrent protection per cord feed. If the power system for the equipment rack is installed on a branch circuit with more than 20 amperes of protection, you must provide supplemental protection for the 6400-S. The overall current rating of a 6400-S configured with two power supplies is less than 4 amperes.
Installing the 6400-S • Rating: For U.S./Canada cords must be UL Listed/CSA Certified type SJT, 18-3 AWG. For outside U.S./Canada cords must be flexible harmonized () or VDE certified cord with 3 x 0.75 mm conductors rated 250 VAC. • Connector, wall outlet end: Cords must be terminated in grounding-type male plug designed for use in your region. The connector must have certification marks showing certification by an agency acceptable in your region and for U.S.
User Guide V2IU 6400-S Converged Network Appliance Voltage • Minimum tolerance = -38VDC • Nominal rating = -48 to -60VDC • Maximum tolerance = -75VDS • Maximum input current = 17.0 Amps The power supply will power-off if the DC input is less than -34 VDC.
3 Configuring the V2IU 6400-S Configure the 6400-S using a web browser such as Internet Explorer or Netscape Navigator. The 6400-S is shipped with a pre-configured IP address for its Subscriber (Port 1) interface. This chapter gives you the information you need to get started.
User Guide V2IU 6400-S Converged Network Appliance 3. Press Return. The Main Configuration Menu appears. 4. To log in, select Network from the navigation bar. 5. In the Connect to pop-up enter the following default information: — For username: root — For password: default Caution 3-2 To maintain your network security, be sure to change the default username and password as described under Changing the administration password on page 7-1.
Configuring the V2IU 6400-S 6. Continue to configure the system using the information provided in subsequent chapters of this guide. Logging in and out of the 6400-S You are prompted to log in every time you point a new browser session to the Configuration URL. To log out, simply close your browser. Navigating through the configuration pages Navigate through the configuration pages from the navigation bar.
User Guide V2IU 6400-S Converged Network Appliance Menu Description Network Through the Network page, you can configure a wide range of multimedia network services.

Configuring the V2IU 6400-S 2. In the System menu, select Network Information. 3. Scroll through the Network Information page to view: — Routing information — Link status — Interface information Routing Information The system routing table contains the static routes for the hosts and networks that are on the Provider side of the 6400-S.
User Guide V2IU 6400-S Converged Network Appliance Link Status Link Status displays the status of the Ethernet connections. Ethernet auto negotiation is often unreliable, especially between different vendors or old and new networking equipment. Failure of auto negotiation is generally not a cause for concern. However, if the negotiated rates change intermittently, or the link is down or there is no link, the link rate may need to be set manually on the Set Link Rate page.
Configuring the V2IU 6400-S 2. In the System menu, select System Information. 3. Scroll through the System Information page to view: — System uptime — Number of active streams — Recent call log — Process information — Memory usage — System logging messages System uptime System Uptime displays the current time, the amount of time elapsed since the last system reboot, and the system load averages for the past one, five, and 15 minutes.
User Guide V2IU 6400-S Converged Network Appliance Recent Call Log The Recent Call Log displays quality information about calls that are in progress or have recently completed. If a call falls below the configured MOS Threshold, a system log message is created. The MOS score for a call is always displayed when the call is completed. Detailed statistics for the call are reported in the Advanced MOS syslog message.
4 Configuring Network Settings You can configure the 6400-S for: • Subscriber interface settings. • Provider interface settings. • Network settings. Optionally, you can: Before Starting • Enabling remote system logging. • Configure a different interface for managing the 6400-S.

User Guide V2IU 6400-S Converged Network Appliance Note The vast majority of Ethernet networking devices including the 6400-S use "autonegotiate" as a default setting. Chances are that you will not have to set the Ethernet link rate. Please use caution if manually configuring the link rate, as a speed or duplex mismatch will result in a loss of connectivity. If needed, configure the rate of the physical Ethernet port on the 6400-S.
Configuring Network Settings Setting Description 10baseT-HD 10Mbits per second using half duplex transmission 10baseT-FD 10Mbits per second using full duplex transmission 100baseT-HD 100Mbits per second using half duplex transmission 100baseT-FD 100Mbits per second using full duplex transmission Autonegotiate The 6400-S autonegotiates link rate and duplex with the directly attached device. 5.

Press Submit.
5 Configuring VoIP An application-layer gateway provides basic proxy features for voice and video over IP traffic. Serving as an ALG proxy, the 6400-S provides Network Address Translation (NAT) services for the protected softswitch, gatekeeper or other media devices. It maps multiple devices on the subscriber interface (public) to a single IP address on the provider interface (private).
User Guide V2IU 6400-S Converged Network Appliance To configure VoIP ALG: 1. In the navigation bar, select VoIP ALG. 2. On the VoIP ALG page, enter information as follows: Field Description MGCP Server IP Address If a MGCP ALG is needed, enter the IP address for the MGCP Server as provided. This address should be reached via the Provider side Ethernet port. The MGCP server provides media gateway control protocol service to IP phones, client adapters and gateways.
Configuring VoIP Field Description SIP Server Address The SIP server provides session-initialization protocol service to IP phones, client adapters and gateways. If a SIP ALG is needed, enter the address (either an IP or URL) for the SIP Server. This address should be reached via the Provider side Ethernet port. SIP Server Port If a SIP ALG is needed, enter a port for the SIP Server Port. Always hairpin SIP media Normally set to False.
User Guide V2IU 6400-S Converged Network Appliance Field Description SIP Register pacing If the SIP Expires override field is set to a lower value, the number of registration messages may overload the soft-switch. In order to prevent this, you can set the SIP Register pacing field to the number of seconds to wait before forwarding a register message from one phone to the soft-switch. Any register messages received before this time will be locally answered by the 6400-S.
Configuring VoIP Field Description Automatic MGCP Audit The Automatic MGCP Audit flag specifies whether MGCP clients should be automatically audited by sending a message to each client and wait for a response. Audit Cycle Interval The Audit Cycle Interval specifies how often these messages should be sent out to the clients. For each cycle, all endpoints are audited so the rate of messages being sent is dependent on the number of clients currently registered.
User Guide V2IU 6400-S Converged Network Appliance Field Description SIP LAN side Gateway The SIP LAN Side Gateway is used to configure a LAN side SIP gateway to which calls that are not for a registered phone can be sent. The name of the gateway is a locally meaningful name. These two fields must both be filled in, or be empty. Gateway Name The name of a subscriber PSTN gateway or a single SIP proxy for multiple PSTN gateways.
