UIM-T1

T1 Uplink Interface Module

Installation Instructions

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 equipment.

The following components should be included:

1 UIM-T1
4 #6 Phillips Panhead Internal Locking Screws
2 #6 Phillips Beige Flathead Screws

If there is any 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. Verify switch configuration.

Ensure that the DIP switches on the UIM-T1 circuit board are positioned correctly (according to desired
configurations) prior to installing the UIM-T1 on a Multiplexer Uplink Module or in a Mini DSLAM. There
are eight DIP switches located on the top side of the circuit board, opposite the faceplate. Switches are
numbered from left to right, starting with Switch #1 on the left and ending with Switch #8 on the right.
Switches 1-2 and 7-8 are not used. Configurations for switches 3-6 are as follows:

Frame Type & Line Coding
Switch Configuration

Switch #3 Frame Type Switch #4 Line Coding
down ESF down B8ZS
up SF up AMI

SF = Super Frame
ESF = Extended Super Frame
B8ZS = Bipolar with 8 Zero Substitution
AMI = Alternate Mark Inversion

Required tool for installation: Phillips screwdriver.

UIM-T1 Installation in an IP DSLAM

Affix the UIM-T1 to a Multiplexer Uplink Module (MUM).

NOTE

The UIM-T1 may be attached to a MUM that has already been in service, although you must remove
the MUM from the IP DSLAM in order to do so.

Removal of a MUM from an IP DSLAM chassis that is powered up will not
affect the operational status of other modules within the chassis;
it will, however, disengage the IP DSLAM's upstream network connection.

a. Place the MUM on a flat surface with the circuit board facing up.

b. Select a port on the MUM for UIM-T1 installation; either port (1 or 2) may be used.

Although not required for operational purposes, if redundancy is desired, two UIMs
may be installed on the MUM, one in each port.

c. Remove the blanking plate* from the selected port.

d. Carefully slide the faceplate of the UIM-T1 under the lip of the MUM faceplate at the

selected port opening such that the UIM-T1 circuit board is facedown and the UIM-T1
label shows through the port opening with the model name along the right-hand edge.

e. Ensure the mounting holes on the UIM-T1 are lined up with the corresponding pems

on the MUM and the board-to-board connector key pins are properly aligned.

f. Gently press down with even pressure on all four corners of the UIM-T1 until the

board-to-board connector is fully seated.

g. Secure the boards together at the pems with the (4) provided panhead screws.

h. Secure the UIM-T1 faceplate to the MUM faceplate using the (2) provided beige

flathead screws.

CAUTION

Install the MUM in an IP DSLAM chassis.

*Blanking plates should be stored for possible future use. If a UIM-T1 is removed from a MUM,
it must be replaced with either another UIM or a blanking plate. DO NOT INSTALL A MUM WITH
AN EMPTY UIM PORT INTO AN IP DSLAM.

The IPD12000 is a fourteen slot chassis; slots 1-12 are reserved for Access Modules and
slots 13-14 are reserved for Multiplexer Uplink Modules (MUMs). The IPD4000 is a five slot
chassis; slots 1-4 are reserved for Access Modules and slot 5 is reserved for a MUM.

220-0000070 rev01

a. Align the MUM with the slot module guides of the chosen slot for installation (either

slot 13 or 14 on the IPD12000 or slot 5 on the IPD4000).

b. Slide the MUM firmly into the chassis. DO NOT USE EXCESS FORCE.

c. Tighten the fastening screws on the MUM faceplate.

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

UIM-T1 Installation in a Mini DSLAM

CAUTION

Disconnect all power sources from the Mini DSLAM before installing the UIM-T1.

a. Remove the (8) screws securing the Mini DSLAM chassis and carefully lift off the chassis

cover. Set the screws aside.

b. Select a port on the Mini DSLAM for UIM-T1 installation; either port (1 or 2) may be used.

Although not required for operational purposes, if redundancy is desired, two UIMs may be
installed in the Mini DSLAM, one in each port.

c. Remove the blanking plate* from the selected port.

d. Carefully slide the faceplate of the UIM-T1 under the inside lip of the Mini DSLAM at the

selected port opening such that the UIM-T1 circuit board is facedown and the UIM-T1 label
shows through the port opening with the model name along the right-hand edge.

e. Ensure the mounting holes on the UIM-T1 are lined up with the corresponding pems on the

Mini DSLAM board and the board-to-board connector key pins are properly aligned.

f. Gently press down with even pressure on all four corners of the UIM-T1 until the board-to-

board connector is fully seated.

g. Secure the boards together at the pems with the (4) provided panhead screws.

h. Secure the UIM-T1 faceplate to the front of the Mini DSLAM chassis using the (2) provided

beige flathead screws.

i. Replace the Mini DSLAM chassis cover and secure with the original (8) screws.

CAUTION

220-0000070 rev01

*Blanking plates should be stored for possible future use. If a UIM-T1 is removed from a Mini DSLAM,
it must be replaced with either another UIM or a blanking plate. DO NOT OPERATE A MINI DSLAM
WITH AN EMPTY UIM PORT.

4. Connect the T1 Line.

Plug the T1 cable into the T1 RJ45 port on the UIM-T1 faceplate. Verify the connection; the T1 Lnk LED
will pulse (once per second) to indicate the T1 connection is established and operational.

NOTE

T1 RJ45 Port Pinout

Pin 1 Rx Ring Pin 5 Tx Tip
Pin 2 Rx Tip Pin 6 not used
Pin 3 not used Pin 7 not used
Pin 4 Tx Ring Pin 8 not used

A T1 Uplink Interface Module (UIM-T1) must be connected via T1 line to a T1 network extender provider
unit (TNE1500-P or TNE1500-P-12-AC/DC) or to an IP DSLAM Access Module (TAM1500-12). A UIM-T1 to
T1 subscriber (TNE1500-S) connection will not function.
