Chapter 3: Summary of services The G450 offers various services, which are described in Media gateway services on page 25, LAN services on page 31, and WAN services on page 32. Media gateway services The Avaya G450 Media Gateway provides a telephone exchange service, supporting the connection of various types of telephones and outside telephone lines. Telephones and lines are connected to the G450 via media modules on the chassis.
Summary of services Physical media — G450 There are various types of telephones and lines supported by the G450 and access ports provided for their connection. Telephones The G450 supports IP telephones, Avaya DCP telephones, analog telephones, and BRI telephones. For information about which Avaya telephones are supported, see Appendix B: Supported Avaya telephones. Telephones must be connected to the correct type of port for the telephone type.
Media gateway services Outside telephone lines The table below lists which modules you can use to connect each type of outside line. See Chapter 2: Optional components for more information about each type of port and media module. Table 5: Outside telephone lines supported and ports provided Line Type Ports ISDN line ISDN ports on the MM720 and MM722 BRI media modules. Analog trunks Analog trunk ports on the MM714 analog media module. Universal analog ports on MM711.
Summary of services See Chapter 2: Optional components for information about the S8300 Server module. Configuring G450 options The G450 provides the following configuration options to help you ensure continuous telephone services: ● You can configure the G450 to use up to four MGCs. If the MGC is an S8710, S8720, or S8730, the first server on the list will normally be the primary C-LAN board connected to the S8xxx server.
Media gateway services ● You can configure the Avaya CM to support the auto fallback feature, which enables a G450 being serviced by an LSP to return to its primary MGC automatically when the connection is restored between the G450 and the MGC. When the G450 is being served by its LSP, it automatically attempts to register with its MGC at periodic intervals. The MGC can deny registration in cases in which it is overwhelmed with call processing, or in other configurable circumstances.
Summary of services ● Intelligent call routing ● Application programming interfaces Avaya CM software applications ● Determine where to connect your telephone call based on the number you dial ● Assign numbers to local telephones ● Play dial tones, busy signals, and prerecorded voice announcements ● Allow or prohibit access to outside lines for specific telephones ● Assign telephone numbers and buttons to special features ● Exchange call switching information with older telephone switches th
LAN services Contact closure The contact closure feature is a controllable relay providing dry contacts for various applications. To implement the contact closure feature, connect an Avaya Partner Contact Closure Adjunct box to the CCA port on the G450 chassis. The adjunct box provides two contact closures that can be operated in either a “normally closed” or “normally open” state. The contact closures can control devices such as devices that automatically lock or unlock doors or voice recording units.
Summary of services Rapid Spanning Tree Protocol (RSTP) The IEEE 802.1D (STP) and IEEE 802.1w (RSTP) Spanning Tree Protocols are supported on the ETH LAN ports. Port mirroring The G450 supports network traffic monitoring by port mirroring. You can configure port mirroring on any LAN port. You implement port mirroring by connecting an external traffic probe device to one of the LAN ports.
WAN services Physical media To use the G450 as the endpoint device for a WAN, install a WAN media module and connect the WAN line to a port on the media module. When you connect a WAN line to a media module, the G450 serves as the router for the WAN line. You can also use the fixed ETH WAN Fast Ethernet port as a WAN endpoint by configuring the port’s interface for PPPoE encapsulation (ADSL modem) or Ethernet-DHCP/static IP (cable modem).
Summary of services WAN features The G450 supports the following WAN features: ● Traffic shaping. The traffic shaping function estimates the parameters of the incoming traffic and takes action if it measures traffic exceeding agreed parameters. The action could be to drop the packets or mark them as being high drop priority. ● PPP over channeled and fractional E1/T1. The G450 has the ability to map several PPP sessions to a single E1/T1 interface.
WAN services ● Policy-based routing. The G450 features policy-based routing, which uses a policy list structure to implement a routing scheme based on traffic source, destination, type, and other characteristics. You can use policy-based routing lists (PBR lists) to determine the routing of packets that match the rules defined in the list.
Summary of services ● Fragmentation ● Static routes ● Policy based routing ● Distribution lists ● Dynamic IP addresses ● DNS resolver ● Unnumbered IP interfaces ● SYN cookies ● Keepalive packets ● Object tracking ● Backup interfaces 36 Administration for the Avaya G450 Media Gateway
