    NEC SL2100 supports the use of IP Phones. These telephones provide the same functionality as a multiline telephone but use the data network rather then the traditional telecoms infrastructure. This can reduce costs and allow the use of NEC SL2100 telephones in locations that would not normally be supported by multiline telephones.

  • Page 47: Chapter 6 Network Design Considerations

    1 INTRODUCTION ECTION This chapter explains some issues that should be considered when planning a NEC SL2100 VoIP installation. This is a generalized explanation and therefore does not discuss vendor-specific issues and solutions. Typically, different solutions are implemented by different manufacturers.
  • Page 48 With intelligent discard mechanisms, IP telephony/VoIP systems try to synchronize a communication flow by selective packet discard, in an effort to avoid the walkie-talkie phenomenon caused when two sides of a conversation have significant latency. NEC SL2100 incorporates a Jitter Buffer to avoid these problems.
  • Page 49: Figure 6-1 Layer 2 Diagram (802.1Q)

    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 50: Section 3 Internet Based Connections (Xdsl, Cable, Etc.)

    SL2100 ISSUE 1.0 • IP Precedence - Layer 3 QoS: Allows you to specify the class of service for a packet. You use the three precedence bits in the IPv4 header type of service (ToS) field for this purpose. Using the ToS bits, you can define up to six classes of service.
  • Page 51: Section 4 Firewalls And Nat

    – but once the data has exited the local router/cable modem it is at the mercy of the Internet. When implementing NEC SL2100 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 52 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 SL2100 device to be open, or to place the NEC SL2100 outside of the firewall.

    VoIP switch and terminal. The common scenario for remote IP deployment is: • Implementation of an IP Phone with a public IP address talking with an NEC SL2100 behind NAT. An example would be a telecommuter.
  • Page 54 Each CODEC has a set frame length. This is the time that the frame encapsulates. For G.729 and G. 711 the frame length is 10ms. It is possible to configure the packet size in the NEC SL2100 programming. To do this, we tell the NEC SL2100 how many frames to encapsulate into each packet for transmission.
  • Page 55: Section 6 Quality Of Service (Qos) Implementation

    ISSUE 1.0 SL2100 bandwidth is also being used for a large amount of header information. If we add several frames to the packet, less packets are transmitted and therefore have less header information sent. If we add many voice frames to each packet, less bandwidth is being used. However, this does have disadvantages.

  • Page 60: Table 6-2 Layer 3 Qos Example

    QoS does not function only by using the ToS field (i.e., Marking the VoIP packets). It is an end-to-end process and requires configuration on all networking devices. Packet Marking is the first step in this process and is often the only step that the NEC dealer performs. Table 6-2 Layer 3 QoS Example...

    Engineering Task Force) in RFC2543 and RFC3261. SIP trunking is the term used for linking a PBX, such as the NEC SL2100 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.
  • Page 70: Figure 7-1 Common Ip Network Using Nec Sl2100 Sip Trunk

    Currently, however, SIP Centrex Transfer is not supported. If a common carrier supports SIP, the NEC SL2100 can connect the SIP Carrier and outgoing calls to the PSTN (Public Switched Telephone Network) network and the common IP network using an NEC SL2100 SIP trunk.
  • Page 71: Section 4 Sip Trunk Overview

    By default, the NEC SL2100 is assigned a static IP address and runs behind a NAT router. When using an NEC SL2100 on a LAN behind an NAPT router, forward port 5060 to the IP address of the NEC SL2100 CPU-C1 (commonly called the SL2100 CPU) since the signaling is handled by the CPU-C1.

By default when an SL2100 with a VoIPDB is installed in a customer’s network, the SL2100 will try and request IP Addressing information from the local DHCP server (DHCP Client Feature). The DHCP server can provide the SL2100 with the following information: •...

    Depending on how QOS policies are built in the network, assignments may be needed in both the CPU and IP terminal. The NEC SL2100 supports the flagging of packets at layer 2 (VLAN tagging 802.1Q/802.1P) and at layer 3 levels.
  • Page 113 ISSUE 1.0 SL2100 13.5 VLANs A VLAN is used to logically break up the network and minimize broadcast domains. Without VLANS, the network must be physically segmented to break up broadcast domains. Each network segment is then connected through a routing device adding latency and cost. Latency is a delay in the transmission of data and is caused by routing packets from one LAN to another.
