12-Port and 24-Port ADSL Access Multiplexers with Full Rate and G.lite Operational Modes
1.0 ADSL ACCESS MULTIPLEXER MODEL TYPES
The AAM8000-12 and the AAM8000-24 (Annex A) are twelve and twenty-four port ADSL Access
Multiplexers, with both Full Rate and G.lite operational modes, that support Plain Old Telephone Service
(POTS) across lower frequencies (up to 4 kHz).
The AAM8000-24B (Annex B) is a 24-port Access Multiplexer, with both Full Rate and G.lite operational
modes, that supports Integrated Services Digital Network (ISDN) across lower frequencies: up to 80 kHz
over a Two Binary, One Quaternary (2B1Q) line and up to 100 kHz over a Four Binary, Three Ternary (4B3T)
line.
All three of the above ADSL Access Multiplexer models exceed the International Telecommunications
Union Telecommunication Standardization Sector (ITU-T) Recommendation G.992.1 minimum
requirements of 640 kbps upstream and 6,000 kbps downstream.
2.0 INSTALLATION
CAUTION
2.1 Unpack and inspect the AAM8000
If there is visible damage, do not attempt to connect the device; contact Customer Support at 1-877638-2638 (001-603-427-0600 for international customers) or Support@NetToNet.com.
2.2 Install the AAM8000 in an IP DSLAM chassis
Net to Net Technologies' IP DSLAM interface modules are hot swappable; installing or removing an
interface module while the chassis is powered up does not affect the operational status of other
interface modules within the chassis. The IPD12000 is a fourteen slot chassis; slots 1-12 are
reserved for interface modules (such as the AAM8000) and slots 13-14 are reserved for MUMs.
Interface modules may be placed in any order in slots 1-12. The IPD4000 is a five slot chassis; slots
1-4 are reserved for interface modules and slot 5 is reserved for a MUM.
Net to Net Technologies strongly recommends the use of proper electrostatic discharge (ESD) precautions when
handling this equipment.
NOTE
There must be a Multiplexer Uplink Module (MUM) installed in the IP DSLAM chassis in order for interface
modules to operate.

Align the AAM8000 with the slot module guides of the chosen slot for installation
(slot 1-12 on the IPD12000 or slot 1-4 on the IPD4000).
z
Slide the AAM8000 firmly into the chassis. DO NOT USE EXCESS FORCE.
z
Secure the AAM8000 by tightening the fastening screws on the module faceplate.
z
Verify that the PWR (Power) LED on the AAM8000 faceplate is illuminated.
2.3 Connect the ADSL Line(s)
Plug the ADSL cable into the RJ21 port of the chosen slot on the back of the IP DSLAM. For each port
being connected to a remote ADSL modem, verify that the ADSL link has been established; the ADSL
LK LED for that port will illuminate solid or flashing green to indicate the connection has been made.
Link up time for connections between the AAM8000 and remote ADSL modems can vary from one to
five minutes depending on the quality, gauge and distance of the copper cables.

4.0 AAM8000 MANAGEMENT
Once the AAM8000 has been installed, operational mode, bandwidth and all other configurations are
software selectable. Dependent upon the MUM model installed in your DSLAM, the AAM8000 can be
configured via Command Line Interface (CLI), Simple Network Management Protocol (SNMP) and/or Net to
Net Technologies' web-based Network Management System (NMS). For further information regarding
AAM8000 management and configuration please refer to Net to Net Technologies' NMS Management User
Guide and/or CLI and SNMP Management User Guide.
4.1 Via NMS
Net to Net Technologies' Network Management System (NMS) is an embedded web server that
resides within the firmware of IP DSLAM MUMs (select models only). This web server maintains
statistical and configuration data for the AAM8000 and includes a scaled-down version of Simple
Network Management Protocol (SNMP v1.0).
NOTE
If your IP DSLAM is newly installed and has not yet been set up for management access, you must configure
the IP Address, Subnet Mask and Gateway (via either NMS or CLI) before you will be able to access data or
complete any other configurations. See the NMS Management User Guide or the CLI and SNMP Management
User Guide for initial configuration instructions.
4.1.1 Establish a Connection with the IP DSLAM MUM
Establish a connection with your IP DSLAM MUM either directly (through the Ethernet RJ45
MGMT Port on the MUM faceplate) or, if the system has been so configured, from a PC on your
local network. For direct connections, verify that the MGMT LNK LED on the MUM faceplate is
illuminated (indicating the connection has been established).
4.1.2 Launch a Web Browser
Launch a web browser on your PC such as Microsoft Internet Explorer (v4.0 or higher) or
Netscape Navigator (v4.0 or higher).
210-0000039 rev 07
4.1.3 Enter the IP Address
Enter the DSLAM's IP address* into the address field at the top of your browser window. Press
the Enter key.
4.1.4 Log In
Log in with your assigned username and password.* Please note that General Users have read
only access; for AAM8000 configuration you must log in as a Superuser.

Administrator or Information Technology Manager for assistance.
Once you have logged in as a Superuser, you may make configuration changes to the AAM8000, and
any other interface modules installed in the IP DSLAM, as desired. For more detailed information
regarding AAM8000 parameters and configuration, refer to Section 5.0 of this manual and/or the
NMS Management User Guide.
4.2 Via CLI
Interface modules in an IP DSLAM with a Command Line Interface (CLI) compatible MUM (select
models only) can be managed with a Terminal Emulator program (loaded onto your PC) via a set of
commands and sub-commands/qualifiers.
4.2.1 Establish a Connection with the IP DSLAM MUM
Establish a direct connection with the MUM through the RS232 COM Port on the MUM
faceplate.
4.2.2 Launch a Terminal Emulator

password* will appear. Please note that for AAM8000 configuration you must log in as a
Superuser (General Users have read only access).
*If your username and/or password are unknown, contact your System Administrator or
Information Technology Manager for assistance.
Once you have logged in as a Superuser, you may make configuration changes to the AAM8000, and
any other interface modules installed in the IP DSLAM, as desired. For more detailed information
regarding AAM8000 parameters and configuration, refer to Section 5.0 of this manual and/or the
CLI and SNMP Management User Guide.
210-0000039 rev 07
4.3 Via SNMP
Simple Network Management Protocol (SNMP) is the standard for management of Transmission
Control Protocol/Internet Protocol (TCP/IP) networks and network devices. Interface modules in an
IP DSLAM with an SNMP compatible MUM can be managed with a MIB Browser program (loaded
onto your PC) via a set of Object Identifiers (OIDs). OIDs are strings of numbers specifying various
configuration commands and requests for data.
N
the IP Address, Subnet Mask and Gateway (via either NMS or CLI) before you will be able to utilize SNMP. See
the NMS Management User Guide or CLI and SNMP Management User Guide for initial configuration
instructions.
If your IP DSLAM is newly installed and has not yet been set up for management access, you must configure
OTE
4.3.1 Establish a Connection with the IP DSLAM MUM
Establish a connection with the MUM either directly (through the Ethernet RJ45 MGMT port on
the MUM faceplate) or, if the system has been so configured, from a PC on your local network.
For direct connections verify that the MGMT LNK LED on the MUM faceplate is illuminated
(indicating the connection has been established).
4.3.2 Launch a MIB Browser
Launch a MIB Browser program on your PC. If you have not yet downloaded the MIBs to your
PC or local network, you can obtain the Net to Net enterprise MIBs from
ftp://ftp.nettonet.com/download/mibs and the supported portions of MIB-II from RFC 1213 at
http://www.ietf.org/rfc.html . After downloading the MIBs, you will need to compile them into
your MIB Browser; see your MIB Browser user manual for further instruction.
Once the MIBs have been compiled, you will be able to make configuration changes to the
AAM8000, and any other interface modules installed in the IP DSLAM, as desired. For more detailed
information regarding AAM8000 parameters and configuration, refer to Section 5.0 below and /or
the CLI and SNMP Management User Guide.
5.0 AAM8000 PARAMETERS
Parameters common to all interface module models are defined in both the NMS Management User Guide
and the CLI and SNMP Management User Guide. Parameters specific to the AAM8000 are outlined below.
5.1 Standard Mode
5.1.1 Multimode (Default)
An AAM8000 port set to Multimode will detect and match the operational mode of the remote
ADSL modem to which it's connected.
5.1.2 Full Rate: G_DMT, T1_413 or ALCTL
An AAM8000 port set at a full rate mode (G.DMT, T1.413 or Alcatel) and using a single line for
both phone and data requires installation of an in-line splitter at both the Central Office (or
other IP DSLAM location) and the customer premises.
210-0000039 rev 07
5.1.3 G_LITE
An AAM8000 port set at G.lite and using a single line for both phone and data requires
installation of an in-line splitter at the Central Office (or other IP DSLAM location) and
installation of microfilters at the customer premises.
5.2 Port Mode
5.2.1 Adaptive (Default)
An AAM8000 port set to Adaptive will automatically train up to the best possible speed
supported by the AAM8000, the remote ADSL modem and the copper cable pair.
5.2.2 On
An AAM8000 port set to ON requires upstream and downstream bandwidths to be specified
individually; see Section 5.3 Speed.
5.2.3 Off
An AAM8000 port set to OFF has been administratively turned off.
5.3 Speed
The default AAM8000 bandwidth setting is Adaptive, allowing each port to train up to the best
possible speed circumstances will allow. The eventual outcome could be any combination of existing
upstream and downstream bandwidths and may or may not be reflected in the following tables.
When Port Mode is set to ON, upstream and downstream bandwidths must be selected manually for
that port; see the NMS Management User Guide and/or the CLI and SNMP Management User Guide
for further instruction regarding parameter configuration. Distance capabilities listed below assume
the use of 26 American Wire Gauge (AWG) cable; connections made with cable of a greater gauge
(e.g., 24 AWG) will link up at greater distances. The units may not link up if the cable is in poor
condition or if the cable distance is greater than a particular bandwidth will support.
Remote ADSL modems determine line speed through their communication with the AAM8000.
NOTE
Maximum possible distances are shown in the following tables for various sample combinations of
upstream and downstream speeds over a typical line. Data given is meant solely as a guide in
determining achievable distances at various bandwidth settings; these tables are not
comprehensive. The many attainable combinations of upstream and downstream bandwidth, along with
corresponding speed possibilities for each, are far more numerous than what is feasible to list here.

5.4 VPI/VCI Detect
ADSL data travels by way of Asynchronous Transfer Mode (ATM) Cells across Permanent Virtual
Circuits (PVCs). Each PVC consists of one Virtual Channel across one Virtual Path as identified by a
Virtual Channel Identifier (VCI) and Virtual Path Identifier (VPI). The AAM8000 supports one PVC per
port.
z
VPI (Virtual Path Identifier): an 8-bit field in ATM cell headers that routes the cell
over the correct Virtual Path (VP)
z
VCI (Virtual Channel Identifier): a 16-bit field in ATM cell headers identifying the
Virtual Channel (VC), within the VP, over which a stream of cells will travel.
5.4.1 ON (Default)
When the VPI/VCI Detect function is set to ON, a port will automatically "snoop" the line to
determine the VPI and VCI settings of the remote ADSL modem to which its connected and
then set itself accordingly. If, however, no ATM cells are detected (at any VPI/VCI setting), the
port will default to VPI 0 and VCI 35 until such time as it does detect ATM cells from the remote
ADSL modem. The port will then automatically reconfigure the VPI and VCI with the same
settings at which the ATM cells were detected.
5.4.2 OFF
When the VPI/VCI Detect function is set to OFF, the VPI and VCI values for that port default to 0
and 35 (respectively) UNLESS the port was previously set at VPI/VCI Detect ON and had
already detected the VPI and VCI settings of the remote ADSL modem. In this case, turning the
VPI/VCI Detect function OFF will essentially lock in those previously detected settings until
such time as the VPI and VCI values are altered manually.
NOTE
If you wish to set VPI and VCI values manually, the VPI/VCI Detect function should be set to OFF
before the VPI and VCI values are entered. When manually configuring VPI and VCI, each port must be
assigned the same VPI and VCI values as the remote ADSL modem to which it's connected or the units
will not be able to communicate.
5.5 Frame Type
Frame type is the ADSL data encapsulation method for carrying traffic over an ATM network as
defined by the Internet Engineering Task Force (IETF) Request for Comment (RFC) 1483:
210-0000039 rev 07
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.
NOTE
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.
