Standards
The two main groups that create recommendations and standards in the telecommunications field are ITU –
T (International Telecommunication Union – Telecommunications Standardization Sector) and ANSI
(American National Standards Institute). Standards vary slightly for both organizations, so please select the
correct organization in the Link Management field in menu 2.1. Your Network Service Provider (NSP)
should provide you with this information.
Press Space Bar to Toggle.

Field
Link This function is responsible for monitoring the up/down
Management= status and error performance of an individual link. If
failure occurs, it also initiates recovery actions for the
restoration of the failed link. Press the [SPACEBAR] and
then [ENTER] to select which standard is compatible
with your Prestige. Both the Prestige and the peer must
use the same standard. LMI (Local Management
Interface) is a management protocol that provides
information about the status of PVC-to-network access
devices. Some Copper Mountain DSLAMs do not
support this protocol, so you may need to choose No
LMI (default for Copper Mountain encapsulation only)
when you do not wish LMI packets to be sent.
