Also: SAM2000QV-12 (2B1Q) and SAM2000V-12 (CAP)
1.0 VoSDSL ACCESS MODULE MODELS
VoSDSL 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 SAM2000GV-12
The SAM2000GV-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 SAM2000QV-12
The SAM2000QV-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 SAM2000V-12
The SAM2000V-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, "SAM2000GV" is utilized to indicate all three VoSDSL access multiplexer models;
information given applies to all three models except as individually stated or otherwise noted.

2.3.2 Voice Connection(s)
The SAM2000GV has Foreign Exchange Office (FXO) capability for connection to voice switches
or Private Branch Exchanges (PBXs). Net to Net Technologies' remote VoSHDSL modems
(SNE2000GV-Ss) have Foreign Exchange Station (FXS) capability for connection to an analog
station (phone, fax, modem, etc.). Individual voice connections can be verified via the Voice
Link (Lnk) LED on the front of the remote SNE2000GV-S; it will flash or pulse green to indicate
activity. Refer to Net to Net's SNE2000GV-S Installation Instructions for further information.
2.3.3 SHDSL Connection(s)
Verify your SHDSL connections; the SHDSL Link (LK) LED for each connected port on the
SAM2000GV will illuminate solid or pulsing green. Link up time for SHDSL connections
between the SAM2000GV and remote VoSHDSL modems can vary from one to five minutes
depending on the quality, gauge and distance of the copper cables. Default bandwidth is 272
kbps.

4.0 SAM2000GV MANAGEMENT
Once your SAM2000GV has been installed, bandwidth and other configurations are software selectable via
your IP DSLAM's MUM. Dependent upon the MUM model installed, the SAM2000GV 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.
If you have an IPD12000 with two MUMs, configuration alterations can be made to a SAM2000GV 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.

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 SAM2000GV-12, SAM2000QV-12 and SAM2000-12.
NOTE
The SAM2000GV-12, SAM2000QV-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).
