Management System Configuration Defaults
TAM1500-12 Circuit Defaults
Data Storage
Configuration backup is inherent in the TAM1500-12. Upon initial power up of the IP DSLAM,
the default parameters of the TAM1500-12 will remain in place unless changed through NMS.
Once changed, new configurations will automatically be recorded in the Random Access
Memory (RAM) of the TAM1500-12 and the Non-Volatile Random Access Memory (NVRAM) of
the MUM. While data stored in TAM1500-12 RAM will be erased if the unit loses power, data
stored within MUM NVRAM will remain intact (even if the unit loses power) unless deliberately
cleared or reconfigured.
TAM1500-12 CIRCUIT CONFIGURATION
Circuit configurations common to all Access Module models are defined in the Management User
Guide for IP and Mini DSLAMs. Circuit configurations specific to T1 technology are outlined below.
Default settings for any of these may be altered via the Circuit Configuration window of Net to Net's
Network Management System (NMS).
Speed
There are eight timeslot/bandwidth options for the T1 link; default is 1,536 kbps across all 24
channels. Remote T1 modems determine line speed through their communication with the
TAM1500-12.
