Fastmux L2-E

  • FASTmux L2-E model offers:
    • 4ADSL lines
    • 4x2Mbps IMA network uplink
  • FASTmux L3 expansion unit offers
    • 6 additionalADSL lines
  • FASTmux is the world’s smallest DSLAM and represents an ideal solution when space is at a premium. Variable installation kits are offered ensuring installation in any space available

BBS 10

Initial investment

ΒΒS 10 and ΒΒS 12 Advantages

  • BBSOffers Unique Continuous Per Port Cost Reduction As You Expand (“Pay as you grow”)
  • BBS has the ADSL and ATM functionality of large scale DSLAMs but is designed to facilitate the ADSL network build out opportunities with the
    • lowest up front equipment investment,
    • lowest total equipment investment, as well as
    • continuous per port cost reductions as you expand
  • BBS units are transferred easily where needed from CO to ONUs and vise versa
  • Capable of supporting future services such as Voice over DSL,Video on Demand, Video multicasting.
  • Interoperability with large range of CPEs guaranteed by the ΑLCATEL ADSL chipset
slide23

ΒΒS Management System

  • BBS systems are manageable through an SNMP agent that is accessable in two ways:
    • in-band through an ATM connection using RFC 1483 encapsulation or
    • out-of-band through an RS-232 Craft Interface on the faceplate of BBS10.
  • The tasks performed using the BBS EMS software are:
    • Network configuration
    • Configuration / reconfiguration of E1 and ADSL parameters
    • Addition / Removal of VCs/VPs
    • Assignment of communication and alarm profiles
    • Monitoring of E1 and ADSL port status
    • System upgrade viaTFTP
