1.0 INSTALLATION
1.1 Unpack and Inspect the EIM2000
If there is visible damage, do not attempt to connect the device; contact Customer Support at 1-877-
638-2638 (1-603-427-0600 for international customers) or [email protected].
1.2 Verify EIM2000 Switch Settings
1.2.1 Switch 2
1.2.2 Switch 3
Switch 3 indicates to the IP DSLAM's MUM whether the EIM2000 will be acting as an E1
provider or an E1 subscriber. Default, in the UP position, dictates that the EIM2000 will be
acting as a provider. In most cases, this will be the desired setting. The EIM2000 can,
however, be configured to act as an E1 subscriber, if so desired, by placing Switch 3 in the
DOWN position.
CAUTION Net to Net Technologies strongly recommends the use of proper electrostatic discharge (ESD) precautions when
handling this equipment.
The EIM2000 houses a bank of eight [8] switches at the rear of the
module (opposite the faceplate). Switches are numbered from left to
right, 1 - 8. Switches 1 and 4-8 are not used.
NOTE EIM2000s with printed circuit boards (PCBs) at rev 810-0000AA have eight switch banks. Section 1.2.1 and
1.2.2 below refer to the switch bank labeled "SW 7"; all switches on the other seven switch banks should be in
the default "up" position. PCBs at any rev other than 810-0000AA have only one switch bank.
CAUTION Switch 2 indicates, to the IP DSLAM's MUM, that the module is an E1
inverse multiplexer and MUST be in the DOWN position. The EIM2000
will NOT achieve link if Switch 2 is in the UP position.
Provider Mode Subscriber Mode
NOTE You will NOT be able to set speed or timing configurations on an EIM2000 in subscriber mode. These
settings will be determined via each port's communication with its respective partner E1 provider.

1.3 Install the EIM2000 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 and IPD12000E are fourteen slot chassis; slots
1-12 are reserved for interface modules (such as the EIM2000) and slots 13-14 are reserved for
MUMs. Interface modules may be placed in any order in slots 1-12. The IPD4000 and IPD4000E are
five slot chassis; slots 1-4 are reserved for interface modules and slot 5 is reserved for a MUM.
1.3.1 Align the EIM2000 with the IP DSLAM Slot Module Guides
Slot 1-12 on the IPD12000(E) or slot 1-4 on the IPD4000(E).
NOTE There must be a Multiplexer Uplink Module (MUM) with an Uplink Interface Module (UIM) installed in your IP
DSLAM chassis in order for interface modules to operate.

1.3.3 Verify that the EIM2000 is Receiving Power
The PWR (Power) LED on the EIM2000 faceplate will illuminate green.
1.3.4 Secure the EIM2000 in the IP DSLAM Chassis
Tighten the fastening screws on the module faceplate with a Philips or Flathead screwdriver.
If your IP DSLAM is not yet powered up,
refer to the IP DSLAM Installation

1.4 Connect the E1 Line(s)
1.4.1 Local Connection
1.4.1.1 Select the Appropriate RJ21 Connector(s)
E1 cables must be connected according to the IP DSLAM slot in which the EIM2000 was
installed. In previous illustrations the EIM2000 was installed in Slot 3, therefore the E1
cable(s) should be plugged into the third RJ21 connector(s) from the right.
1.4.1.1.1 IPD12000E or IPD4000E
Each interface module slot on the IPD12000E and IPD4000E has two [2]
corresponding RJ21 connectors located on the back of the chassis. The bottom
row of RJ21 connectors (A) on the IPD12000E provides the E1 connection for
EIM2000 ports 1-12 and the top row of RJ21 connectors (B) provides the E1
connection for EIM2000 ports 13-24. On the IPD4000E, the A connectors for each
interface module slot are on the left and the B connectors are on the right.
NOTE The EIM2000-24 utilizes both rows of RJ21 connectors on the IPD12000E and IPD4000E.
The EIM2000-12 utilizes only the A connectors on the IPD12000E (lower row) and
IPD4000E (left-hand side).

1.4.1.1.2 IPD12000 or IPD4000
Each interface module slot on the IPD12000 and IPD4000 has one corresponding
RJ21 port located on the back of the chassis which will connect EIM2000 E1 ports
1-12.
EIM2000-24
For the
EIM2000-24,
you must
connect an
E1 cable to
both the
A and B
Connectors
in order to
utilize
all 24 E1 ports.
EIM2000-12
For the
EIM2000-12,
connect an E1
cable
to the A
Connector
only; the B
Connector
has no function
for the
EIM2000-12.
IPD12000E IPD12000E
NOTE Although the EIM2000-24 can function in an IPD12000 or IPD4000, you will not be able to
utilize ports 13-24; the IPD12000 and IPD4000 do not have the second row of B
connectors necessary to support additional E1 ports.

EIM2000-24 and EIM2000-12
There is only one RJ21 port, for each module
slot, to which an E1 connection can be made.
This connection will support E1 ports 1-12
on both the EIM2000-12 and the EIM2000-24;
you will not be able to utilize ports 13-24
on an EIM2000-24 installed in an IPD12000 or
IPD4000.

1.4.1.2 Detach the Velcro Strap and Position the E1 Cable RJ21 Connector(s)
1.4.1.2.1 IPD12000 and IPD12000E
Detach the Velcro strap and pull it open to the right, leaving it looped under the
connector frame on the right side. Slide the RJ21 connector of your E1 cable
underneath the Velcro and press it firmly into the RJ21 connector on the chassis.
1.4.1.2.2 IPD4000 and IPD4000E
On the IPD4000 and IPD4000E the RJ21 connectors attach horizontally with the
E1 cable trailing off to the left. Detach the Velcro strap and pull it open and
downward, leaving it looped under the bottom edge of the connector frame. Slide
the RJ21 connector of your E1 cable underneath the Velcro, from the left, and
press it firmly into the RJ21 connector on the chassis.
1.4.1.3 Secure the Connector(s)
1.4.1.3.1 IPD12000 and IPD12000E
Screw the top of the T1 cable connector into the jack screw at the top of the RJ21
connector frame on the chassis. If you are using a 120° or 180° cable, both the
top and the bottom of the cable connector should be secured to the RJ21
connector frame on the chassis.
NOTE The RJ21 connector cannot be screwed into the connector frame on the IPD12000. An E1
connection on the IPD12000 can only be secured via the Velcro strap.
