1.2 Configure the T1 Ports
The T1 Configuration Switches for both Port 1 and Port 2 are on the component side of the UIM-2T1
circuit board, opposite the faceplate/label. When facing the Configuration Switches, Port 1 switches
are on the left and Port 2 switches are on the right. Switches for both ports are numbered from left
to right, #1-8.
Installation Instructions
CAUTION Net to Net Technologies strongly recommends the use of proper electrostatic discharge (ESD) precautions when
handling this equipment.
NOTE Port 2 Configuration Switches on the UIM-2T1 are NOT USED: frame type, line code and line attenuation for
Port 2 are determined by the Port 1 switch settings. BOTH ports determine speed and timing configurations via
communication with the remote T1 equipment to which the UIM-2T1 is connected.

1.2.1 Frame Type
Frame type is the data encapsulation method. A T1 frame consists of 192 data bits (an 8-bit
sample of each of the 24 T1 data channels), plus a synchronization bit, transmitted at a rate of
8,000 frames per second across the T1 line.
1.2.1.1 Extended Super Frame
Extended Super Frame (ESF) format, used in Wide Area Networks (WANs), assembles
data into 24-frame transmission clusters and integrates Facilities Data Link (FDL) which
provides in-service monitoring and diagnostics as well as Cyclic Redundancy Check (CRC)
which scrutinizes data integrity and detects line errors.
1.2.1.2 Super Frame
Super Frame (SF) format assembles data into 12-frame transmission clusters. SF does
not utilize FDL or CRC.
1.2.2 Line Code
Line code is the T1 mode of transmission. The two line code options outlined below fall within
the International Telecommunication Union - Telecommunication Standardization Sector (ITU-
T) G.703 Standards for Transmission Facilities.
1.2.2.1 Bipolar with 8 Zero Substitution
Bipolar with 8 Zero Substitution (B8ZS) is used to accommodate the minimum ones
density requirement in the North American public network. B8ZS line encoding helps
prevent loss of synchronization between the UIM-2T1 and remote T1 equipment by using
bipolar violations to guarantee the presence of pulses in the T1 line.
1.2.2.2 Alternate Mark Inversion
Alternate Mark Inversion (AMI) simply alternates positive and negative pulses. Although
AMI links typically encounter long strings of zeros which can potentially cause loss of
synchronization between units, Net to Net Technologies' products meet the North
American minimum ones density requirement internally such that, even with AMI, loss of
synchronization is prevented between the UIM-2T1 and remote T1 equipment (just as it
is with B8ZS).
1.2.3 Line Attenuation
Shorter distances between the UIM-2T1 and remote T1 equipment require increasing line
attenuation in order to prevent the T1 signal from becoming too strong for repeaters, switches
and other T1 transmission equipment that may be encountered along the line. Increased
transmit line attenuation translates to decreased transmit line amplitude.
Port 1 Configuration Switches #5 and #6 work in tandem with one another to provide four
attenuation options for the T1 line(s):

up Super Frame
Switch #4 Line Code

up Alternate Mark Inversion
220-0000084 rev 01

1.2.3.1 0 dB
Receivers on most newer T1 transmission equipment can automatically adjust for
incoming amplitude, allowing them to run at zero attenuation regardless of distance.
1.2.3.2 -7.5 dB, -15 dB, -22.5 dB
Some older T1 transmission equipment cannot automatically adjust for incoming
amplitude and line attenuation must be set accordingly.
1.3 Install the UIM-2T1
1.3.1 IP DSLAM Installation
The UIM-2T1 provides an upstream network connection, via a multiplexer uplink module
(MUM), for Net to Net Technologies' IP DSLAMs; neither an IP DSLAM nor a MUM can function
without an uplink interface module (UIM).
1.3.1.1 Affix the UIM-2T1 to a MUM
zSelect a port on the MUM for installation of the UIM-2T1: either port (1 or 2) may
be used. Although not required for operational purposes, if redundancy is desired
two UIMs may be installed on a MUM, one in each port.
zRemove the blanking plate from the selected port.
zCarefully slide the faceplate of the UIM-2T1 under the lip of the MUM faceplate at
the selected port opening such that the UIM-2T1 circuit board is facedown and the
UIM-2T1 label shows through the MUM port opening with the UIM-2T1 model name
along the right-hand edge.
zEnsure that the mounting holes on the UIM-2T1 are lined up with the
corresponding pems on the MUM circuit board and that the board-to-board
connector key pins are properly aligned.
zGently press down across the center of the UIM-2T1 circuit board until the board-
t
o-board connector is fully seated.
Switch #5 Switch #6 Attenuation
down down 0 dB

NOTE The UIM-2T1 can be installed on a MUM that is already in service, though you must remove the
MUM from the IP DSLAM chassis in order to do so. Removal of a MUM from a powered IP
DSLAM will not affect the operational status of other modules within the chassis; it will
however, disengage the IP DSLAM's upstream network connection.
CAUTION Blanking plates should be stored for possible future use: if a UIM-2T1 is
removed from a MUM, it must be replaced with either another UIM or a
blanking plate. DO NOT OPERATE AN IP DSLAM WITH A MUM THAT HAS AN
OPEN UIM PORT.

zSecure the UIM-2T1 faceplate to the MUM faceplate using the (2) provided beige
flathead screws.
1.3.1.2 Install the MUM in an IP DSLAM Chassis
The IPD12000 is a fourteen slot chassis; slots 1-12 are reserved for interface 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 interface modules and slot 5 is reserved for a
MUM.
zAlign 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).
zSlide the MUM firmly into the chassis. DO NOT USE EXCESS FORCE.
zVerify that the PWR (Power) LED on the MUM faceplate is illuminated.

off the chassis cover. Set the screws aside.
zSelect a port on the Mini DSLAM for UIM-2T1 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 a Mini DSLAM, one in each port.
zRemove the blanking plate from the selected port.
zCarefully slide the faceplate of the UIM-2T1 under the inside lip of the Mini DSLAM at the
selected port opening such that the UIM-2T1 circuit board is facedown and the UIM-2T1
label shows through the Mini DSLAM port opening with the UIM-2T1 model name along
the right-hand edge.
zEnsure that the mounting holes on the UIM-2T1 are lined up with the corresponding
pems on the Mini DSLAM circuit board and that the board-to-board connector key pins
are properly aligned.
zGently press across the center of the UIM-2T1 until the board-to-board connector is fully
seated.
CAUTION Disconnect all power sources from the Mini DSLAM before installing the UIM-2T1.

2.0 CONNECTING THE T1 LINE(S)
The primary feature of the UIM-2T1 is loop bonding capability, though it functions with a single T1
connection as well.
2.1 Loop Bonded Connection
Using two T1 lines for one network connection (loop bonding) will net twice the speed and data
passing capability as a single T1 connection. A second T1 line can also be considered a backup for
the first, and vice versa, should one of the lines become disabled. A UIM-2T1 can only establish loop
bonded connections with other Net to Net loop bonding capable T1 provider equipment. See Net to
Net's T1 Loop Bonding Product to Product Feature Compatability list
(http://www.nettonet.com/support/docs/230-0000034 ).
Plug the T1 cables into the T1 RJ45 Ports on the UIM-2T1 faceplate; the order of connection is not
important. Verify both connections: the Port 1 and Port 2 Lnk LEDs on the UIM-2T1 faceplate will
flash green to indicate the connections are established and operational.
2.2 Single T1 Connection
A single line connection can be established between a UIM-2T1 and any of Net to Net's T1 provider
equipment, regardless of loop bonding capability.
Plug the T1 cable into one of the two T1 RJ45 ports on the UIM-2T1 faceplate; either port (1 or 2)
may be used. Verify the connection: the T1 Lnk LED on the UIM-2T1 faceplate (Port 1 Lnk or Port 2
Lnk depending upon which port was connected) will flash green to indicate the connection is
established and operational.
2.3 T1 RJ45 Pinout
If you are using a shielded T1 cable for your network connection, it must be grounded through pins
3, 6, 7 and 8.
