    Service (QoS) initiatives, all of which are controlled by the network and Internet Service Providers. Because these variables are not in NEC control, it cannot guarantee the performance of the user’s IP-based remote voice solution. Therefore, NEC recommends connecting VoIP equipment through a local area network using a Private IP address.

  • Page 26: Configure Ip Trunks

    VoIP daughter board ports are allotted in accordance with the number of Licensed ports for the particular IP Application. The NEC SL1100 system now has the required information about the remote destinations and the configuration is complete. The only remaining task is to configure F-Route to route calls to remote destinations via the IP trunks.

  • Page 27: Chapter 4 General Ip Configuration

    General IP Configuration Enhancements With SL1100 Version 1200 (V1.20) and VoIP daughter board installed, half duplex connections are not supported. For troubleshooting purposes, a managed switch capable of port mirroring is required to capture packet data from the SL1100 VoIPDB Ethernet port.

  • Page 28: Network Addressing Overview

    Issue 6.0 NEC SL1100 ETWORK DDRESSING VERVIEW ECTION Before connecting the system to a data network, it is necessary to obtain the relevant IP Addressing information. This information is supplied by the IT Manager or Network Administrator at the customer site.

  • Page 29: Dhcp

    Network control may be easier with DHCP as there is no need to assign and program individual IP addresses for the LAN equipment. To use a dynamic IP address, a DHCP server must be provided. The SL1100 can be configured to be the DHCP server for the customers network. Before the DHCP server in the SL1100 can be enabled, the DHCP client function must first be disabled.

    ONNECTION ECTION To test the NEC SL1100 network connection, it is possible to use the ICMP (Internet Control Message Protocol) Ping command. This basically sends a small amount of data from one device to another and then waits for a reply. This test confirms that the IP addressing and physical connection are good.

  • Page 63: Section 2 Qos

    Cisco, etc.) has slightly different methods of implementing QoS and these are not discussed in this document. This chapter provides an overview to classify voice traffic on the NEC SL1100 so that the network equipment can impose QoS. QoS Definitions This section lists common definitions used with QoS for VoIP.
  • Page 64 Issue 6.0 NEC SL1100 the call quality is usually considered poor. It is also important to remember that packets can get lost. IP is a best effort networking protocol. This means the network tries to get the information there, but there is no guarantee.

  • Page 65: Voice Quality Improvements

    NEC SL1100 Issue 6.0 walkie-talkie phenomenon caused when two sides of a conversation have significant latency. NEC SL1100 incorporates a Jitter Buffer to avoid these problems. Packet Loss During a voice transmission, loss of multiple bits or packets of stream may cause an audible pop that can become annoying to the user.

  • Page 66: Types Of Classifications For Traffic For Qos

    The down side to this is that most networks may not have these services available, where Ethernet is very widely used. This is usually outside the control of the installer and therefore NEC strongly advises users to do more research on other layer 2 protocols before trying to implement them in their voice network.

  • Page 68: Section 4 Firewalls And Nat

    Issue 6.0 NEC SL1100 DSL, C NTERNET ASED ONNECTIONS ABLE ECTION Internet-based connections are becoming increasingly popular. This is mainly due to the speed and cost of xDSL and cable modem connections. For data applications, these types of connection are generally acceptable. For Voice over IP applications several issues should be taken into consideration.

  • Page 69: Understanding The Infrastructure

    – but once the data has exited the local router/cable modem it is at the mercy of the Internet. When implementing NEC SL1100 IP over Internet based connections it is very important that these factors are considered, and that the customer is made aware that neither the installer nor NEC are held responsible for any quality issues experienced.

  • Page 70: Firewall Integration

    A list of these ports is shown below, however it should be noted that the preferred solution would be to allow all ports on the NEC SL1100 device to be open, or to place the NEC SL1100 outside of the firewall.

  • Page 75: Bandwidth

    NEC SL1100 Issue 6.0 Bandwidth The bandwidth required for VoIP calls depends on several factors, including: Number of simultaneous calls  CODEC used  Frame Size  Data Networking Protocol used  The more frames encapsulated into each packet, the less bandwidth is required.

  • Page 76: Figure 6-3 Network Bottleneck Example

    Issue 6.0 NEC SL1100 Not all network hardware supports QoS and each manufacturer has their own methods of implementing QoS. The explanations below are as generic as possible. The installer/maintainer of the data network should be familiar with the QoS characteristics of their equipment and should be able to configure the equipment accordingly.

  • Page 77: Figure 6-4 Voice And Data Network Implementation

    NEC SL1100 Issue 6.0 For most data applications this packet loss/delay is not critical. For example, a delay of one to five seconds to transmit an email is imperceptible. When VoIP is implemented, this loss/delay has a massive impact on the voice quality.

  • Page 78: Figure 6-5 Priority Queuing On Voice And Data Networks

    Issue 6.0 NEC SL1100 After the router is configured for QoS, it examines incoming packets and allocates a priority to the packet. Figure 6-5 Priority Queuing on Voice and Data Networks shows the affect priority queuing has on voice and data networks. The packets arrive randomly.

    Issue 6.0 NEC SL1100 IP Precedence IP Precedence is a QoS method that combines a priority value with different on/off parameters; Delay, Throughput, Reliability and Cost. The MBZ (Must be Zero) bit is not used. Using the ToS bits, you can define up to eight classes of service. Other devices configured throughout the network can then use these bits to determine how to treat the packet in regard to the type of service to grant it.

    SIP (Session Initiation Protocol) is used for Voice over IP. It is defined by the IETF (Internet Engineering Task Force) in RFC2543 and RFC3261. SIP trunking is the term used for linking a PBX, such as the NEC SL1100 system, to the public telephone network by means of VoIP. This provides the ability for users to place and receive communications and services from any location and for networks to identify the users wherever they are located.

    NEC SL1100 blocks outgoing calls with SIP trunks. All SIP trunk ports are placed into a busy status. If the NEC SL1100 has trunk groups that include both SIP trunks and ISDN trunks, and all SIP trunks are busy, a user can make an outgoing call using an ISDN trunk as a bypass.

  • Page 177: Some Network Considerations

    13.8 Some Network Considerations When adding the SL1100 to a customers network there are many things to be aware of. Before implementation a detailed network diagram of the existing network must be obtained from the customer. This diagram may provide you with information about possible network conditions that can prevent or hinder the VoIP equipment from functioning correctly.

  • Page 178: Figure 9-23 Nec Sl1100 Network Example No. 1

    Figure 9-23 NEC SL1100 Network Example No. 1 The green arrow in the diagram above represents the data packets leaving the IP phone destined for the SL1100 on the Headquarters LAN. The firewall on the Headquarters network is not configured to recognize the UDP ports used by the NEC equipment thus blocking them and resulting in registration failure.

  • Page 179: Figure 9-24 Nec Sl1100 Network Example No. 2

    Network equipment limitations may sometimes restrict this ability resulting in no voice path on VoIP calls between sites. When this happens Peer-to-Peer must be disabled in the SL1100. The downside to disabling Peer-to-Peer is using more DSPs and consumption of additional bandwidth at the MAIN location.
  • Page 180 To correct this issue another VPN connection between sites B and C is required. If an additional VPN cannot be implemented, due to network limitations, the Peer-to-Peer feature can be disabled in the NEC SL1100. With Peer-to-Peer disabled, all packets (Signaling and Voice) route through the VoIPDB card.

    After the necessary ports (station or trunk) are removed from a system, a restart of the SL1100 is required. Every time a system in an SL Net network is reset, a port count is performed. If the network port count is below 168 ports (below Version 3500) or 256 port (Version 3500 and above), all systems are allowed to communicate.
