IAM144-12

12-Port IDSL Access Multiplexer

CAUTION

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

INSTALLATION

1. Unpack and inspect the IAM144-12.

If there is visible damage, do not attempt to connect the device; contact Customer Support at 1­877-638-2638 (001-603-427-0600 for international customers) or [e-mail].

2. Install the IAM144-12 in an IP DSLAM chassis.

NOTE

All Access Multiplexer Modules for Net to Net Technologies' IP DSLAMs are hot swappable;
installing or removing an Access Module while the chassis is powered up does not affect the
operational status of other Access Modules within the chassis. The IPD12000 is a fourteen slot
chassis; slots 1-12 are reserved for Access Modules (such as the IAM144-12) and slots 13-14 are
reserved for Multiplexer Uplink Modules (such as the MUM200-2). Access Modules may be
placed in any order in slots 1-12. The IPD4000 is a five slot chassis; slots 1-4 are reserved for
Access Modules and slot 5 is reserved for a Multiplexer Uplink Module.

There must be a Multiplexer Uplink Module installed in the IP DSLAM chassis in order for Access Modules to
operate.

a. Align the IAM144-12 with the slot module guides of the chosen slot for installation (slot 1-

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

b. Slide the IAM144-12 firmly into the chassis. DO NOT USE EXCESS FORCE.

c. Secure the IAM144-12 by tightening the fastening screws on the module faceplate.

d. Verify that the PWR (Power) LED on the IAM144-12 faceplate is illuminated.

3. Connect the IDSL Line(s).

Plug the IDSL cable into the RJ21 connector for the chosen slot on the back of the IP DSLAM.
For each port being connected to a remote IDSL modem, verify that the IDSL link has been
established; the IDSL LK LED for that port will show steady illumination 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. Default bandwidth for the IAM144-12 is 144
kbps.

NOTE

Once the IAM144-12 has been installed, bandwidth and other configurations are software selectable via Net to Net
Technologies' Network Management System (NMS). For further information regarding Access Module management
and configuration please refer to the Management User Guide for IP and Mini DSLAMs.

OVERVIEW

IAM144-12 Management

Statistical and configuration data for the IAM144-12 are maintained in an embedded web server
that resides within the firmware of Net to Net Technologies' Multiplexer Uplink Modules
(MUMs). This firmware contains Net to Net's Network Management System (NMS) and Simple
Network Management Protocol (SNMP).

Accessing IAM144-12 data in a newly installed IP DSLAM

a. Connect your PC to the Ethernet RJ45 MGMT port located on the faceplate of the

MUM installed in your IP DSLAM.

b. Verify the connection; solid illumination of the MGMT LNK LED on the MUM

faceplate indicates the connection has been established.

c. Launch a web browser such as Microsoft Internet Explorer (v4.0 or higher) or

Netscape Navigator (v4.0 or higher).

d. Type the default IP address into the address field at the top of your browser and

press the Enter key.

e. Log in with a default username and password (both of which are case sensitive).

Please note that General Users have "read only" access; for NMS configuration you
must log in as a Superuser.

NOTE

Accessing IAM144-12 data in a previously installed IP DSLAM

Once accessed initially, the management system within the MUM can be configured such that NMS
and SNMP can be reached from any computer on your network. For further instruction please refer
to the Management User Guide for IP and Mini DSLAMs.

a. 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 network.

b. For direct connections verify that the MGMT LNK LED on the MUM faceplate is

illuminated, indicating the connection has been established.

c. Launch a web browser such as Microsoft Internet Explorer (v4.0 or higher) or

Netscape Navigator (v4.0 or higher).

d. Enter the assigned IP address* into the address field at the top of your browser

window. Press the Enter key.

e. Log in with your assigned username and password.* Please note that General Users

have "read only" access; for NMS configuration you must log in as a Superuser.

*If the IP address, username or password is unknown, contact your System Administrator
or Information Technology Manager.

Default Settings

No configuration is necessary for the IAM144-12 to operate at default settings. If however, a
change is required, default settings can easily be modified within NMS. For information
regarding specific parameter configurations, refer to the Management User Guide for IP and
Mini DSLAMs.

Circuit Configuration

Circuit configurations for the IAM144-12 are defined in the Management User Guide for IP and
Mini DSLAMs. Default settings may be altered via the Circuit Configuration window of Net to
Net's Network Management System (NMS).

Data Storage

Configuration backup is inherent in the IAM144-12. Upon initial power up of the IP DSLAM, the
default parameters of the IAM144-12 will remain in place unless changed through NMS. Once
changed, new configurations will automatically be recorded in the Random Access Memory
(RAM) of the IAM144-12 and the Non-Volatile Random Access Memory (NVRAM) of the MUM.
While data stored in IAM144-12 RAM will be erased if the unit loses power, data stored within
MUM NVRAM will remain intact (even if the unit loses power) unless deliberately cleared or
reconfigured.

ADDITIONAL INFORMATION

Speed

There are two bandwidth options for the IDSL link: 128 kbps and 144 kbps. Default is 144 kbps.
Under optimal conditions, distance capabilities are 18,000 feet (5,486 meters) at either speed.
The units may not link up if the cable distance is greater than 18,000 feet - assuming the use of
26 American Wire Gauge (AWG) cable. Connections made with cable of a lesser gauge (e.g., 24
AWG) will link up at greater distances. Remote IDSL modems determine line speed through
their communication with the IAM144-12.
