5.5.1 1483LLC (Default)
Logical Link Control (LLC) encapsulation multiplexes multiple protocols over a single ATM
Virtual Circuit. 1483LLC is the protocol-identifying frame header.
5.5.2 1483VCM
Virtual Circuit Multiplexing (VCM) creates a separate ATM Virtual Circuit connection for each
protocol type without additional encapsulation.
6.0 DATA STORAGE
6.1 RAM and NVRAM
Configuration backup is inherent in the AAM8000. Upon initial power up of the IP DSLAM, default
parameters of the AAM8000 will remain in place unless changed through NMS, CLI or SNMP. Once
changed, new configurations will automatically be recorded in both the Random Access Memory
(RAM) of the AAM8000 and the Non-Volatile Random Access Memory (NVRAM) of the MUM. While
data stored in AAM8000 RAM will be erased if the module is removed from the IP DSLAM or the IP
DSLAM loses power, interface module data stored within MUM NVRAM will remain intact (even if the
unit loses power) unless deliberately cleared or reconfigured.
6.2 Local File
Individual port configurations can be saved locally on your PC as a backup, and/or for use as a
template for future configurations. Once the AAM8000 has been configured as desired, the settings
can be flash uploaded through a Trivial File Transfer Protocol (TFTP) tool with a GET command and
the following information:
Host name:
[IP DSLAM IP Address]
Remote filename:
NVR_CFG.bin.[superuser password]
Local filename:
[user preference]
Port configuration files can be flash downloaded FROM a local file TO an AAM8000 as well; simply
replace the GET command with a SET command.

OTE
Only individual port configurations can be saved to a local file. Chassis configurations are not flash up or
downloadable; they must be manually configured for each unit.
