  • Page 11: Chapter 1 Mxk

    This chapter provides an overview of the MXK. It includes the following sections: • MXK overview, page 11 • MXK features, page 15 • MXK hardware overview, page 19 MXK overview The MXK platform provides high-density subscriber access concentration in the Zhone Single Line Multi-Service (SLMS) architecture.
  • Page 12 The MXK aggregates local loop traffic from a variety of media and sends it to an upstream device, such as an IP router. The MXK supports GPON, Active Ethernet, ADSL and EFM-SHDSL edge connection technologies and 100/1000 Ethernet and 10 Gigabit (GE) uplinks.
  • Page 13 1.25 Gbps upstream bandwidth per interface as specified in the G.984.1-4 specifications. The MXK 8 port GPON card can support up to 512 GPON subscribers using Class B+ optics. The MXK 4 port GPON card can support up to 256 GPON subscribers using Class B+ optics.
  • Page 14 The MXK-EFM-SHDSL-24 NTP card provides network timing reference and line power. The timing reference enables the card to use the MXK timing as the SHDSL line clocking. This allows an SHDSL CPE to derive timing from the input of the SHDSL lines. It then can use that timing/clocking to provide timing to other subtended devices.The line power feature can be used to power CPEs such as the...

  • Page 15: Mxk Features

    MXK features The MXK has a non-blocking architecture with a high-speed backplane. Each line card on the MXK had a dedicated backplane trace to each of the uplink cards. The MXK chassis, uplink cards, line cards, and SFPs are temperature hardened.

  • Page 16: Voip

    VoIP Voice over IP, also known as Internet Telephony, supports full duplex transmission of voice traffic over IP networks. The MXK supports Media gateway control protocol (MGCP) and Session Initiation Protocol (SIP). MGCP Media gateway control protocol (MGCP) provides the means to interconnect a large number of IP telephony gateways.

  • Page 17: Sip

    As configuration changes are made to the active card, the standby card is automatically updated. Management The MXK can be managed either in-band (VLAN tagged) on uplink Ethernet ports, out-of-band on the 10/100 Ethernet interface, or IP on a bridge. MxK Hardware Installation Guide...

  • Page 18: Data Services

    The uplink card also contains a serial (craft) port for local management. After establishing a connection to the MXK, administrators can manage the device using the Command Line Interface (CLI), Web UI, ZMS, or SNMP. Data services The MXK provides access and aggregation routing functions to connect subscribers to networks.
