Ethernet over E1 Converter

Product Overview

The VCL-ETH-FE1 Interface Converter (Desktop

Version) provides the user with Ethernet over E1
conversion enabling the user to transport Ethernet
data over an E1 link.

The equipment can be installed and used in pairs, with

one terminal being installed at either end of the
network. This equipment can also be used with VCL-
ETH-8-ML and VCL-ETH-16-ML (8E1/16E1 ponit-to-
point IP over TDM product) to meet various application
requirements.

The VCL-ETH-FE1 Interface Converter is an Ethernet extension device utilizing TDM telecom
infrastructure (the telecom network of E1s, or of PDH, SDH and E1/E3/SDH microwave etc. carrying
E1s). It converts the Ethernet data into E1 frame format for transmission over the existing TDM (E1)
links and then re-converts the E1 back into Ethernet data the far-end terminal, to BRIDGE two Ethernet
LANs over the existing E1-based telecom network. The device can effectively utilize the redundant
bandwidth of telecom operators' existing TDM network to transport Ethernet data with low investment.

Application

The equipment may be used for the following purposes:

Bridging Ethernet LANs over existing TDM (E1) telecom network.

Extending Ethernet networks utilizing TDM (E1) landline based telecom infrastructure.
Using telecom network of E1s/PDH/SDH microwave etc. carrying E1s to transport Ethernet data.

Installation and Commissioning

Qualifying the Network

Please ensure that the error code rate each of the E1 circuits connecting to the equipment is
-7.
lower than 10

The transmission time delay difference between the various E1 circuits shall not exceed 8ms.

The Ethernet wire type shall be, crossover when connecting with PC, and straight through when
connecting to an Ethernet switch/HUB. The length of the Ethernet cable shall not exceed 100m.

Grounding

When the device is used with the AC~220V power supply, the 3-core socket must be grounded
for protection.

The other equipment connected with the converter shall also be grounded to earth for protection.

Ethernet over E1 Converter

Installation

Step 1: Power up the equipment. Please ensure that equipment is powered-up prior to connecting
the Ethernet and the E1 links.

Step 2: Connect E1 line on the premise that transmission device, interface converter and
Ethernet converter have safely grounded.

BER test may be conducted on each E1 link using a BERT tester to ensure that the E1
errors are within the permitted limits / threshold.

Step 3: Please configure the Ethernet mode of the Ethernet over E1 equipment at both sides as
well as the Ethernet interfaces of the devices that are connected to the Ethernet over E1
equipment. Connect the ethernet links.

The equipment is used to bridge two LANs. Please ensure that the LANs on both sides of
the link are operating in the same IP domain.

Step 4: Ping over the Ethernet connection from one side to the other (near-end to the far-end) to
verify that the Ethernet connection has been established between the two LANs.

After succeeding in "ping", the user may also check the integrity of each E1 link by connecting E1 link
and then transporting Ethernet data over that E1 link. In the event that the equipment resets repeatedly
or lots of frame errors are noticed, recheck the connection between E1 cable and interface converter,
or E1 cable and transmission device.

E1 Bandwidth Selection

Fractional E1 bandwidth selection is effective only if the encapsulation mode is set to 'HDLC' (i.e. GFP /
HDLC switch is set to 'ON').
The DIP switches for the bandwidth selection are given in the right side-bar of the equipment and the
setting are as follows:

OFF

ON

Working Mode Switch Setting

TS0 TS1-15, 17-31 TS16
Unframed / PCM 31 ON ON ON
Framed (CCS) / PSM 31 OFF Occupied timeslot ON
Multi Framed (CAS) / PCM 30 OFF Occupied timeslot ON OFF

Note: Fraction E1 bandwidth is effective only if the encapsulation mode is set to ‘HDLC’. GFP/HDLC
switch is set to ‘ON’

Example 1: If you wish to use only first five time slots then you need to set the TS0 time slots to OFF
and switch TS1 to TS5 to ON and time slot TS16 will be set to ON.

Example 2: If you wish to carry first eight time slots on 512Kbps, then you need to set the TS0 time
slot OFF and switch TS1 to TS8 to ON (i.e. since each time slot consumes 64Kbps, so 8
time slots will consume 8 x 64Kbps = 512Kbps) and time slot S16 will be set to ON.

Example 3: If you wish to carry twenty time slots on 1.28Mbps (64Kbps x 20) then you need to
set time slot TS0 OFF and TS1 to TS21 time slots to ON. Please remember that the
time slot TS16 will be used as signaling time slot.
