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.

2.0 INSTALLATION

CAUTION

Net to Net Technologies strongly recommends the use of proper electrostatic discharge (ESD) precautions when
handling this equipment.

2.1 Unpack and Inspect the SAM2000G

If there is visible damage, do not attempt to connect the device; contact Customer Support at 1-877­638-2638 (1-603-427-0600 for international customers) or [e-mail]

2.2 Install the SAM2000G in an IP DSLAM Chassis

NOTE

There must be a Multiplexer Uplink Module (MUM) installed in your IP DSLAM chassis in order for interface
modules to operate.

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 for
interface modules such as the SAM2000G, slots 13 and 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
for interface modules, slot 5 is reserved for a MUM.

z

Align the SAM2000G with the module guides in the slot chosen for installation (slot 1-12 on
the IPD12000 or slot 1-4 on the IPD4000).

z

Slide the SAM2000G firmly into the chassis. DO NOT USE EXCESS FORCE.

z

Secure the SAM2000G by tightening the fastening screws on the module faceplate.

z

Verify that the PWR (Power) LED on the SAM2000G faceplate is illuminated.

2.3 Connect the SHDSL Line(s)

.

Plug the SHDSL cable into the RJ21 port, of the chosen slot, on the back of your IP DSLAM. Verify
your connections; the SHDSL LK LED for each connected port will illuminate solid or pulsing green.
Link-up time for connections between the SAM2000G and remote SHDSL modems can vary from
one to five minutes depending on the quality, gauge and distance of the copper cables. Default
bandwidth for the SAM2000G is 272 kbps.
