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


Xdsl services provisioning

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
