SAM2000G-12
12-Port SHDSL Access Multiplexer
Also: SAM2000Q-12 (2B1Q) and SAM2000-12 (CAP)
1.0 SDSL ACCESS MODULE MODELS
SDSL access multiplexers are intended for use in Net to Net Technologies' IPD12000 and IPD4000
DSLAMs. Model types vary by the SDSL line code utilized.
1.1 SAM2000G-12
The SAM2000G-12 operates with Transmission Convergence/Pulse Amplitude Modulation (TC/PAM)
line code: a sixteen-level PAM technique which incorporates advanced Trellis code, precoding,
spectral shaping, equalization circuits and forward error correction. Otherwise known as G.SHDSL or
SHDSL.
1.2 SAM2000Q-12
The SAM2000Q-12 operates with Two Binary, One Quaternary (2B1Q) line code: a four-level PAM
technique which reduces the signaling rate to half of the bit rate.
1.3 SAM2000-12
The SAM2000G-12 operates with Carrierless Amplitude and Phase (CAP) modulation line code:
transmit and receive signals are modulated into two wide-frequency bands that can pass through a
filter without being attenuated.
Throughout this document, "SAM2000G" is utilized to indicate all three SDSL access multiplexer models; information
given applies to all three models except as individually stated or otherwise noted.

4.0 SAM2000G MANAGEMENT
Once your SAM2000G has been installed, bandwidth and other configurations are software selectable via
your IP DSLAM's MUM. Dependent upon the MUM model installed, the SAM2000G may be configured via
Command Line Interface (CLI), Simple Network Management Protocol (SNMP) and/or Net to Net
Technologies' web-based Network Management System (NMS).
If your IP DSLAM is newly installed, configuration of the DSLAM's IP Address, Subnet Mask and Gateway
must be completed, via CLI or NMS, before you will be able to access management data or configure any
other parameters. Refer to the CLI Management User Guide (http://www.nettonet.com/support/docs/210-
0000048) for initial configuration instructions.
210-0000026 rev07
If you have an IPD12000 with two MUMs, configuration alterations can be made to a SAM2000G through either MUM;
most configuration(s) will be saved to the NVRAM of both. Refer to your MUM Installation Instructions for specifics.
NOTE
4.1 Via Command Line Interface (CLI)
4.1.1 Establish a Connection With Your IP DSLAM
Establish a connection between your IP DSLAM and your PC, either directly (through the COM
port on the MUM faceplate) or, if your DSLAM has been configured to allow inband
management, across your local network.
4.1.2 Launch Your Terminal Emulator
Launch a terminal emulator program on your PC. Net to Net Technologies' copyright
information will appear on your screen, followed by a request for username.
4.1.3 Log In
Log in with your assigned username and password. For SAM2000G 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 will be able to make configuration changes to the
SAM2000G, and any other interface modules installed in your IP DSLAM, as desired. For more
detailed information regarding SAM2000G configuration via CLI, refer to Net to Net's CLI
4.2 Via Net to Net's Network Management System (NMS)
4.2.1 Establish a Connection With Your IP DSLAM
Establish a connection between your IP DSLAM and your PC, either directly (through the
10/100 Ethernet MGMT port on the MUM faceplate) or, if your DSLAM has been configured to
allow inband management, across your local network. For direct connections, verify that the
MGMT LNK LED on the MUM faceplate is illuminated.
4.2.2 Launch Your Web Browser
Launch a web browser on your PC such as Microsoft Internet Explorer or Netscape Navigator.
4.2.3 Enter Your DSLAM's IP Address
Enter the DSLAM's IP Address into the address field at the top of your browser window and
press the Enter key.
210-0000026 rev07
4.2.4 Log In
Log in with your assigned username and password. For SAM2000G 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 will be able to make configuration changes to the
SAM2000G, and any other interface modules installed in your IP DSLAM, as desired. For more
detailed information regarding SAM2000G configuration via NMS, refer to Net to Net's NMS
4.3 Via Simple Network Management Protocol (SNMP)
The MUM200-2 does not have SNMP capabilities; you must have a MUM2000-2 installed in your IP DSLAM in
order to access DSLAM management or any interface modules via SNMP.
NOTE
4.3.1 Establish a Connection With Your IP DSLAM
Establish a connection between your IP DSLAM and your PC, either directly (through the
10/100 Ethernet MGMT port on the MUM faceplate) or, if your DSLAM has been configured to
allow inband management, across your local network. For direct connections, verify that the
MGMT LNK LED on the MUM faceplate is illuminated.
4.3.2 Launch Your MIB Browser
Launch a MIB browser program on your PC. If you have not yet downloaded the necessary
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 the Internet
you will need to compile them into your MIB browser; refer to your MIB browser user manual
for further instruction.
Once the MIBs have been compiled, you will be able to make configuration changes to the
SAM2000G, and any other interface modules installed in your IP DSLAM, as desired. For more
detailed information regarding SAM2000G configuration via SNMP, refer to Net to Net's SNMP
5.0 BANDWIDTH AND DISTANCE
Parameters common to all interface module models are defined in the CLI, NMS and SNMP Management User Guides.
Bandwidth, however, is specific to the SAM2000G-12, SAM2000Q-12 and SAM2000-12.
NOTE
210-0000026 rev07
The SAM2000G-12, SAM2000Q-12 and SAM2000-12 each have nine SHDSL bandwidth options; default
is 272 kbps. Distance capabilities at each bandwidth vary, dependent upon the type of line code being
utilized. Distances listed below assume the use of 26 American Wire Gauge (AWG) cable; connections
made with cable of a greater gauge will link up at greater distances. The ports on your module may not link
up if your cables are in poor condition or if cable distances are greater than the configured bandwidth will
support. Although it is sometimes possible for links to be achieved under such conditions, traffic quality
may be effected (e.g., packets may be dropped).

6.0 ADDITIONAL INFORMATION
6.1 Data Storage
Configuration backup is inherent in Net to Net Technologies IP DSLAMs. SAM2000G default
parameters remain in place unless changed via CLI, NMS or SNMP. Once changed, new
configurations are automatically recorded in both RAM and NVRAM.
6.1.1 Memory
6.1.1.1 Random Access Memory (RAM)
Data stored in SAM2000G RAM will be erased if the module is removed from your IP
DSLAM or if your IP DSLAM loses power.
6.1.1.2 Non-Volatile Random Access Memory (NVRAM)
Data stored in the NVRAM of your IP DSLAM's MUM will remain intact (even if your IP
DSLAM loses power) unless deliberately cleared or reconfigured.
6.1.2 Local Files
Management and interface module configurations can be saved on your PC, or local network,
both as a backup and/or for use as a template for future configurations, via the MUM in your
IP DSLAM. Management configurations and all interface module port configurations are saved
210-0000026 rev07
concurrently; SAM2000G configurations cannot be saved independently. Once your IP DSLAM
has been configured as desired (including the SAM2000G), settings can be flash uploaded (to
a local file) through a Trivial File Transfer Protocol (TFTP) tool with a GET command and the
following information:
6.1.2.1 Backup
