Speed  
On the ENE2020-P (only), switches 1 and 2 control the port speed.  
The E1 lines each have 31 channels continually running at 64 kbps for a collective  
bandwidth of 1,984 kbps. The timeslot configuration determines 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 table below.  
Port 1 configuration switches 1 and 2 on the ENE2020-P work together to provide four  
timeslot/bandwidth options for the Port 1 E1 link. Port 2 configuration switches 1 and 2  
on the ENE2020-P provide the timeslot/bandwidth options for the Port 2 E1 link.  
The ENE2020-S determines timeslot and bandwidth configurations for the two E1 links  
via communication with its partner E1 provider unit.

Frame Type  
Switch 3 sets the Frame Type for Port 1 on both the ENE2020-P and the ENE2020-S.  
Switch 3 controls the frame type of both E1 ports (Port 1 and Port 2); frame type for the  
two ports cannot be configured independently.  
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. The ENE2020 can be  
configured to use Cyclic Redundancy Check (CRC) to detect line errors and scrutinize  
data integrity across the E1 line by appending a hexidecimal checksum (calculated from  
the previous E1 frame contents) to the end of each E1 frame. The remote modem then  
makes a similar calculation upon receipt of each E1 frame and compares it to the  
checksum of the ensuing E1 frame.

Line Code  
Switch 4 sets the Line Code for Ports 1 and 2 on both the ENE2020-P and the  
ENE2020-S. Switch 4 controls the line code of both E1 ports (Port 1 and Port 2); line  
code for the two ports cannot be configured independently.  
Line code is the E1 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.  
High Density Binary 3 – High Density Binary 3 (HDB3) is used to accommodate  
the minimum ones density requirement in the European public network. HDB3 line  
encoding helps prevent loss of synchronization between the ENE2020 and remote  
E1 equipment by using bipolar violations to guarantee the presence of pulses in the  
E1 line.  
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, the  
ENE2020 meets the European minimum ones density requirement internally such  
that, even with AMI, loss of synchronization is prevented between the ENE2020 and  
remote E1 equipment (just as it is with HDB3).

Timing  
Switch 7 sets the timing for the ENE2020-P (only). Switch 7 controls the timing of both  
E1 links (Port 1 and Port 2) on the ENE2020-P. The ENE2020-S determines timing for  
the two E1 links via communication with its partner E1 provider unit.  
Timing refers to the clock source for E1 transmission links.  
Local Clock Source – Local clock source refers to timing derived from an oscillator  
onboard the ENE2020-P.  
Loop Clock Source – Loop clock source refers to timing derived from an  
intermediate device.

Connecting the E1 Lines  
The primary feature of the ENE2020 is loop bonding capability, although both the  
provider and subscriber units are able to function with a single E1 connection as well.  
Loop Bonded Connection  
Using two E1 lines for one network connection (loop bonding) will net twice the speed  
and data passing capability as a single E1 connection. A second E1 line also acts as a  
backup should one of the lines become disabled. An ENE2020 can only establish loop  
bonded connections with other Paradyne equipment with the loop bonding feature. See  
Product to Product E1 Loop Bonding Compatibility (document number  
COMP-A2-GK43).  
Procedure  
1. Plug the E1 cables into the E1 RJ45 ports (Port 1 and Port 2) on the back of the  
ENE2020. The order of connection is not important.  
2. Verify both connections: the Port 1 and Port 2 Lnk LEDs on the front of the  
ENE2020 will pulse green to indicate the connections are established and  
operational.  
Single E1 Connection  
A single line connection can be established between an ENE2020-S and any Paradyne  
E1 provider unit, regardless of loop bonding capability. Likewise, a single line connection  
can also be established between an ENE2020-P and any of Paradyne's E1 subscriber  
units, regardless of loop bonding capability.  
Procedure  
1. Plug the E1 cable into one of the two E1 RJ45 ports on the back of the ENE2020;  
either port (Port 1 or Port 2) may be used.  
2. Verify the connection: the E1 link LED on the front of the ENE2020 (Port 1 Lnk or  
Port 2 Lnk depending upon which port was connected) will pulse green to indicate  
the connection is established and operational.

Connecting the Ethernet Line  
The 10/100BaseT Ethernet Port auto-negotiates speed and duplex mode in accordance  
with the remote equipment to which it is connected; Ethernet speed and duplex mode  
configurations cannot be configured on the ENE2020. For the best connection results,  
the remote device (PC, hub, or switch) should be set to auto-negotiate speed and duplex  
mode. If the remote device cannot be configured to auto-negotiate, speed may be set at  
either 10 Mbps or 100 Mbps but duplex mode must be set to Half Duplex. A  
10/100BaseT Ethernet connection will not operate properly if the remote device is set to  
Full Duplex.  
Procedure  
1. Plug the Ethernet cable into the 10/100 Ethernet Port on the back of the ENE2020.  
2. Verify the connection: solid green illumination of the 10/100 Ethernet Connection  
Lnk (Link) LED on the front of the ENE2020 indicates a connection has been  
established. If the Ethernet Lnk LED is illuminated but not the Ethernet 100 LED,  
then a 10 Mbps connection has been established. If the Ethernet Lnk and 100 LEDs  
are both illuminated, then a 100 Mbps connection has been established.  
For most applications, the ENE2020 connects to a PC using a straight-through Ethernet  
cable and to a hub or a switch using a crossover Ethernet cable. For any other  
connection combinations you must verify the pinout of the Ethernet device to which you  
are connecting the ENE2020 in order to determine which type of cable is required.

LED Indicators  
This document describes units manufactured after 13 January 2005. See the prior  
version of this document for information about units manufactured on or before that date.  
Whenever both ENE2020 E1 connections have lost link or have presented an E1 Alarm,  
the Ethernet link will automatically be disabled (as indicated by no illumination of the  
Ethernet 100, Act and Lnk LEDs). Upon reestablishment of at least one of the E1  
connections, the Ethernet link will be reinstated and the Ethernet LEDs will reflect  
current Ethernet Status.
