SIM2000-24

24-Port SDSL Inverse Multiplexer with TC/PAM (G.SHDSL), 2B1Q and CAP Line Encoding

1.0 INSTALLATION

1.1 Unpack and inspect the SIM2000-24

If there is visible damage, do not attempt to connect the device; contact Customer Support at 1-877-

638-2638 (001-603-427-0600 for international customers) or [email protected].

1.2 Install the SIM2000-24 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 SIM2000-24) 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.

zAlign the SIM2000-24 with the slot module guides of the chosen slot for installation

(slot 1-12 on the IPD12000 or slot 1-4 on the IPD4000)

zSlide the SIM2000-24 firmly into the chassis: DO NOT USE EXCESS FORCE

zSecure the SIM2000-24 by tightening the fastening screws on the module faceplate

zVerify that the PWR (Power) LED on the SIM2000-24 faceplate is illuminated

1.3 Connect the SDSL Line(s)

Plug the SDSL cable RJ21 connector into the corresponding RJ21 port on the back of the IP DSLAM. For

most applications, a SIM2000-24 SDSL link requires a STRAIGHT-THROUGH DSL CABLE. The SIM2000-

24 can be connected with a remote SDSL subscriber unit via either a single SDSL line or double SDSL

lines (loop bondin

). For each port bein

connected to a remote SDSL subscriber unit, verify that the

Interface Module User Guide

CAUTION 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.

210-0000049 rev 05

SDSL link has been established; the SDSL LK LED for that port will pulse green to indicate the

connection has been made. Link up time can vary from one to five minutes depending on the quality,

gauge and distance of the copper cables.

(pins 25 and 50 are not used)

1.3.1 Loop Bonded SDSL Connection

Using two SDSL lines for one network connection (loop bonding) will net twice the speed and data

passing capability as a single-line SDSL connection. A second SDSL line can also be considered a

backup for the first, and vice versa, should either line become disabled. Any two SIM2000-24

ports (consecutive or not) may be connected to an SNE2020-S or SNE2020G-S subscriber unit to

establish a loop bonded connection.

1.3.2 Single Line SDSL Connection

A single line connection can be established between a SIM2000-24 and any of Net to Net's SDSL

subscriber units.

1.3.3 Bandwidth and Line Code

There are nine bandwidth options for SIM2000-24 SDSL connections. Distance capabilities vary,

dependent upon the type of line code being utilized. The defaults are TC/PAM line encoding

(G.SHDSL) at 272 kbps. See Section 4.0 SIM2000-24 Parameters for more detailed information

regarding bandwidth and line code.

2.0 DEFAULT SETTINGS

No configuration is necessary for the SIM2000-24 to operate at default settings.

NOTE Net to Net Technologies strongly suggests that any ports on the SIM2000-24 intended for a loop bonded

connection with an SNE2020-S or SNE2020G-S be identically configured prior to connection; bonding ports

with different configurations will likely result in misplaced, misdirected and/or dropped data. See the NMS

Management User Guide and /or the CLI and SNMP Management User Guide for configuration instructions.

If default settings are to be used for both ports, then prior configuration is not necessary and you may

proceed with installation.

3.0 SIM2000-24 MANAGEMENT

Once the SIM2000-24 has been installed, line code, bandwidth and all other configurations are software

selectable. Dependent upon the MUM model installed in your DSLAM, the SIM2000-24 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 SIM2000-

24 management and configuration please refer to Net to Net Technologies' NMS Management User Guide

and/or CLI and SNMP Management User Guide.

3.1 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 SIM2000-24 and includes a scaled-down version of Simple Network

Management Protocol (SNMP v1.0).

3.1.1 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).

3.1.2 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).

3.1.3 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.

3.1.4 Log In

only access; for SIM2000-24 configuration you must log in as a Superuser.

*If the IP address, 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 SIM2000-24, and

any other interface modules installed in the IP DSLAM, as desired. For more detailed information

regarding SIM2000-24 parameters and configuration, refer to Section 4.0 of this manual and/or the

NMS Management User Guide.

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.

210-0000049 rev 05

3.2 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.

3.2.1 Establish a Connection with the IP DSLAM MUM

Establish a direct connection with the MUM through the RS232 COM Port on the MUM faceplate.

3.2.2 Launch a 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.

3.2.3 Log in

password* will appear. Please note that for SIM2000-24 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 SIM2000-24, and

any other interface modules installed in the IP DSLAM, as desired. For more detailed information

regarding SIM2000-24 parameters and configuration, refer to Section 4.0 of this manual and/or the

CLI and SNMP Management User Guide.

3.3 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.

3.3.1 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).

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 utilize SNMP. See the NMS

Management User Guide or CLI and SNMP Management User Guide for initial configuration instructions.

210-0000049 rev 05

3.3.2 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 . Once these have been downloaded, you will need to compile them

into your MIB Browser; see your MIB Browser user manual for further instruction.

Once the MIBs have been downloaded, you will be able to make configuration changes to the SIM2000-

24, and any other interface modules installed in the IP DSLAM, as desired. For more detailed

information regarding SIM2000-24 parameters and configuration, refer to Section 4.0 below and /or

the CLI and SNMP Management User Guide.

4.0 SIM2000-24 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 SIM2000-24 are outlined below.

4.1 Line Code

Line code configuration for the SIM2000-24 applies to all ports; individual ports cannot be configured

with different line codes.

4.1.1 TC/PAM (G.SHDSL) - DEFAULT

Transmission Convergence/Pulse Amplitude Modulation (TC/PAM) line code is a sixteen-level

PAM technique which incorporates advanced Trellis code, precoding, spectral shaping,

equalization circuits and forward error correction. Otherwise known as G.SHDSL.

4.1.2 CAP

Carrierless Amplitude and Phase (CAP) line code modulates transmit and receive signals into two

wide-frequency bands that can pass through a filter without being attenuated.

4.1.3 2B1Q

Two Binary, One Quaternary (2B1Q) line code is a four-level Pulse Amplitude Modulation (PAM)

technique which reduces the signaling rate to half of the bit rate, thereby doubling transmission

efficiency.

4.2 Speed

There are nine bandwidth options for SIM2000-24 SDSL connections; default is 272 kbps. Distance

capabilities 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 (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 SDSL subscriber units determine line speed through their communication with the SIM2000-

24.

210-0000049 rev 05

5.0 DATA STORAGE

5.1 RAM and NVRAM

Configuration backup is inherent in the SIM2000-24. Upon initial power up of the IP DSLAM, default

parameters of the SIM2000-24 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 SIM2000-24 and the Non-Volatile Random Access Memory (NVRAM) of the MUM. While data

stored in SIM2000-24 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.

5.2 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 SIM2000-24 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 a SIM2000-24 as well; simply

replace the GET command with a SET command.
