1.1
Making RS-485 Bus Connections Between Shelves
NOTE
References to common, but differing, parameters between the Total Access
3000 and the Total Access 3010, such as number of slots, will be conveyed
by the convention a/b. The “a” represents the Total Access 3000 parameter
and the “b” represents the Total Access 3010 parameter. For example, the
differing number of access slots in the two platforms, 28 for the Total Access
3000 and 22 for the Total Access 3010, would be displayed “28/22.”
1.1.1
Introduction
Up to 16 Total Access shelves can be linked together for management from a single
shelf designated as host. The other shelves will be configured as clients. This feature
allows conservation of valuable external management ports within the CO and
provides local or remote management for up to 16 shelves from the craft interface on
front of the host SCU or the external management ports.
The daisy chain of shelves linked together via the RS-485 bus can be up to 4000 feet
long. Only one SCU, located at either end of the chain, is designated as the Host SCU.
The SCU that is to function as the Host, must be provisioned as a Host. The SCUs that
are to function as clients must be provisioned as clients. Procedures for designating
SCUs as Host or client are covered in NTP-501 of this system manual.
NOTE
ADTRAN reccomends that the Total Access 3000/3010 shelves not be
daisy-chained when using SNMP. In this configuration, each shelf must be
equipped with a SCU and connected to an Ethernet hub.
1.1.2
Prerequisite Procedures
The Total Access 3000/3010 shelves should be mounted in their permanent location in
the CO before making RS-485 bus connections.
