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 1-877638-2638 (1-603-427-0600 for international customers) or support@nettonet.com.
1.2 Verify EIM2000 Switch Settings
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.
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.
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.
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.

1.3 Install the EIM2000 in an IP DSLAM Chassis
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.
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.

1.4.2 Remote Connection
The EIM2000 is capable of supporting both single-line connections and multiple-line loop
bonded connections, as well as any combination of the two. If the distance(s) between the
EIM2000 and any of the remote E1 equipment is greater than 6,000 feet, the line(s) may
require an E1 repeater.
210-0000054 rev02 EIM2000 User Guide Page 14 of 20
1.4.2.1 Loop Bonded Connection
Using multiple E1 lines for one network connection (loop bonding) will net speed and
data passing capability equal to the cumulative total of the individual single-line
connections. Multiple E1 lines used for one connection can also be considered backup
for each other should one or more of the lines become disabled. Any of the ports on the
EIM2000-12 or EIM2000-24 can be bonded together; it is not necessary for them to be
consecutive.
AUTION
C
All E1 ports intended for a loop bonded connection MUST be identically configured PRIOR to
connection. See Net to Net's NMS Management User Guide and/or CLI Management User
Guide for configuration instructions. If default settings are to be used for bonded ports, then
prior configuration is not necessary and you may proceed with installation.
The E1 equipment to which an EIM2000 is connected must also be E1 loop bonding
capable in order for the EIM2000 to establish a loop bonded connection. Refer to Net to
Net's E1 Loop Bonding Product to Product Feature Compatibility document at
http://www.nettonet.com/support/docs/230-0000035 .
1.4.2.2 Single Line E1 Connection
A single line connection can be established between the EIM2000 and any of Net to
Net's E1 modems.
1.4.3 Verify the Connection
For each port being connected to a remote E1 modem, verify that the E1 link has been
established.
The E1 LK LED of connected ports will illuminate green
to indicate a connection has been made.
Link up should occur within 20 seconds
depending on the quality, gauge and distance
of the copper cable(s).

2.0 E1 PARAMETERS
Parameters common to all of Net to Net's interface modules are defined in Net to Net's management user
guides; refer to the NMS Management User Guide ( http://www.nettonet.com/support/docs/210-
0000048 ) and/or the CLI Management User Guide ( http://www.nettonet.com/support/docs/2100000052 ). Parameters specific to the EIM2000 are outlined below.
2.1 Parameter Defaults
No configuration is necessary for the EIM2000 to operate at default settings.
Parameter Default
Clock Source
Flood Uplink
Frame Type Cyclic Redundancy Check (CRC)
IP Range 1 0.0.0.0 - 255.255.255.255
IP Range 2 0.0.0.0 - 0.0.0.0
Line Code High Density Binary 3 (HDB3)
Priority 0
Protocol ALL
Speed (Single Line) 1,984 kbps
VLAN 0 - 0
VLAN Back-bone 0
Local - provider mode
Loop - subscriber mode
210-0000054 rev02 EIM2000 User Guide Page 17 of 20
2.2 Clock Source
Clock source refers to the timing origination for E1 transmission links.
2.2.1 Local (default-provider mode)
Timing is derived from an oscillator on board the EIM2000.
2.2.2 Loop (default-subscriber mode)
Timing is derives from an intermediate device on the E1 line.
NOTE
Local timing is the default for an EIM2000 in E1 provider mode. Default for an EIM2000 in subscriber mode is
Loop and cannot be modified.
2.3 Frame Type
Frame type is the E1 data encapsulation method. A frame consists of 248 bits (8-bit samples of
each of the 31 E1 data channels plus a synchronization bit) transmitted at a rate of 8,000 frames
per second (1,984 kbps) across the E1 line. EIM2000 frame type configuration options are Cyclic
Redundancy Check or No Cyclic Redundancy Check.
2.3.1 Cyclic Redundancy Check (default)
Cyclic Redundancy Check (CRC) detects line errors and scrutinizes data integrity across the E1
line by appending a CRC character to the end of each data block. The character is a
hexadecimal value calculated from the contents of the data block; if a different value is
calculated at the receiving end than was appended at the originatation point, retransmission is
requested.
2.4 Line Code
Line code is the E1 mode of transmission. The two line code options for the EIM2000 both fall within
the International Telecommunication Union - Telecommunication Standardization Sector (ITU-T)
G.703 Standards for Transmission Facilities.
2.4.1 High Density Binary 3 (default)
High Density Binary 3 (HDB3) line encoding uses bipolar violations to guarantee the presence
of pulses in the E1 line thereby helping to prevent loss of synchronization between the
EIM2000 and remote E1 equipment. HDB3 accommodates the minimum ones density
requirement in the European public network.
2.4.2 Alternate Mark Inversion
Alternate Mark Inversion (AMI) alternates positive and negative pulses across the E1 line.
Although AMI links typically encounter long strings of zeros which can potentially cause loss of
synchronization between E1 units, Net to Net Technologies' E1 products meet the European
minimum ones density requirement internally such that, even with AMI, loss of synchronization
is prevented between the EIM2000 and remote E1 equipment, just as it is with HDB3.
210-0000054 rev02 EIM2000 User Guide Page 18 of 20
2.5 Speed
All E1 lines consist of 31 channels (timeslots) that continually run at 64 kbps for a collective
bandwidth of 1,984 kbps. Timeslot configuration dictates how many of the channels for each port
will actually receive data. Ports configured to operate as fractional E1 lines require contiguous
timeslots as indicated in the chart below.
Single Line T1 Bandwidth (kbps)

COLLECTIVE
SPEED
1,984 1,792 1,536 1,280 1,024 768 512 256
3.0 ADDITIONAL INFORMATION
3.1 Configuration and Management
Default bandwidth utilizes
all 31 timeslots for a
collective speed of 1,984 kbps.
Once the EIM2000 has been installed, all parameter settings are software selectable via Command
Line Interface (CLI), Simple Network Management Protocol (SNMP) and/or Net to Net's Network
Management System (NMS) dependent upon the multiplexer uplink module (MUM) model installed
in your IP DSLAM. Refer to Net to Net's NMS Management User Guide
( http://www.nettonet.com/support/docs/210-0000048 ) and/or CLI Management User Guide
( http://www.nettonet.com/support/docs/210-0000052 ) for further instruction regarding IP DSLAM
management and interface module parameter configuration.
3.2 Data Storage
Upon initial power up of the IP DSLAM, default parameters of the EIM2000 will remain in place
unless changed via NMS, CLI or SNMP. Once changed, new configurations will automatically be
recorded in both the Random Access Memory (RAM) of the EIM2000 and the Non-Volatile Random
Access Memory (NVRAM) of the MUM. While data stored in EIM2000 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 chassis loses power) unless deliberately cleared or
reconfigured.
3.3 European Regulatory Compliance
This Class A product complies with European Norm EN55022.
Warning: In a domestic environment this product may cause radio interference in which case the
user may be required to take adequate measures to correct the situation.
