2 Introduction
This section presents a general introduction to the LEDE1 unit.
The section is closed with a unit view in section "Installation" (page 15).
2.1 General
This document describes the architecture and functions of the LEDE1 unit
and shows how this unit is commissioned and operated as part of the
FOX61x.
The LEDE1 unit is a 1-slot wide service unit of FOX61x and provides 8 E1
(2 Mbit/s) interfaces according to ITU-T G.703. Traffic signals can be
unstructured or structured according to ITU-T G.704.
The E1 interface of the LEDE1 unit can be used as access interface to a
high speed TDM network, e.g. the P12 signals from the E1 interfaces are
transported over SDH.
Another application is in a TDM network where the LEDE1 unit is used as a
transport unit, e.g. the low bit rate data signals from a DTE are transported
via structured P12 signals over the E1 interface.
Figure 1: LEDE1 used as an access unit (top) and as a transport unit (bot-
tom)
The LEDE1 unit accesses the PBUS (FOX61x internal TDM bus) with P0-nc
(n x 64 kbit/s) and P12 (2048 kbit/s) signals.

Pins without a signal designation are not connected.
Please note:
The cables provided by ABB are internally connected for 120 Ω(pins a, b).
Please note:
In transmit direction the b signals are available on three pins per port.
Avoid unintentional connections to the pins with the redundant out-
puts.
Risk of operating trouble!
E1 ports which are not connected at the remote end of the cable can cause
cross talk.
Cross talk onto such an open-ended cable can cause spurious alarms.
Set the administrative state of these ports to “down”.
4.4.2 8 x 2 Mbit/s cable 120 Ω
The 8 x 2 Mbit/s cable for 120 symmetrical termination interfaces each E1
port of the LEDE1 unit. It is an open ended twisted pair cable. The wires of
this cable have to be terminated in an MDF provided by the customer. The
length of the cable can be specified.
Latching clips must be used to secure the cable to the LEDE1 front connec-
tor.
For details on LEDE1 cables, please refer to "1KHW002498 FOX61x Electri-
cal cables".
4.4.3 8 x 2 Mbit/s 75 Ωtermination
The 8 x 2 Mbit/s 75 asymmetrical termination consists of a 120 symmet-
rical cable and an external impedance converter.
Latching clips must be used to secure the cable to the LEDE1 front connec-
tor.
For details on LEDE1 cables, please refer to "1KHW002498 FOX61x Electri-
cal cables".
4.4.4 Fixing the cables to the cable tray
When operating the LEDE1 unit in a FOX615, the cable must be attached to
the cable tray as shown in the Figure 4.

FUNCTIONAL DESCRIPTION
FOX61xLEDE1 19
5 Functional description
This section gives the detailed functional description of the LEDE1 unit as a
P12 access unit in the FOX61x subrack.
Section "P12 termination modes" (page 19) describes the supported P12
traffic signal formats.
The section "Protection" (page 21) presents the available traffic protection
features.
5.1 P12 termination modes
The LEDE1 unit provides different P12 termination modes for the E1 ports.
The termination modes define
• the expected signal structure,
• the timing characteristics,
• the usage for a specific application, e.g. V5 uplink.
The LEDE1 unit supports terminated and transparent P12 transport modes.
Structured signals can be transported in a terminated mode or a transparent
mode. Unstructured signals are transported in a transparent mode.
The termination modes of all E1 ports are configurable independently.
For more information regarding P12 termination modes, cross connections
and CAS configuration please refer to FOX61x TDM Services.
5.1.1 Terminated transport modes
An E1 port of the LEDE1 unit can be configured to one of the following termi-
nated transport modes:
• PCM30:
Structured according to ITU-T G.704, with CAS, without CRC4.
• PCM30C:
Structured according to ITU-T G.704, with CAS, with CRC4.
• PCM31:
Structured according to ITU-T G.704, without CAS, without CRC4.
• PCM31C:
Structured according to ITU-T G.704, without CAS, with CRC4.
In the above terminated transport modes, the time slot 0 of the P12 signal
is analysed in the receive direction (from the network interface) and
regenerated in the transmit direction.
Cross connection and protection switching (P0-nc SNCP/I) is established
on the P0-nc (n x 64 kbit/s) traffic signal layer.
There are two specific termination modes used for the V5 application:
• V5 Uplink:
Structured according to ITU-T G.704, with CRC4.
• V5 Uplink NCI:
Structured according to ITU-T G.704, without CRC4.

FUNCTIONAL DESCRIPTION
20 FOX61xLEDE1
The V5 uplink modes are application specific modes used together with
the V5 protocol converter unit COSI1. V5.x applications terminate the
P12 signal and use all 5 Sa bits.
With V5.1 the Sa bits are fixed. With V5.2 Sa7 is used for the link identifi-
cation control.
For terminated signals the following functions are available:
• CAS (PCM30, PCM30C)
Support of channel associated signalling in time slot 16.
• CRC4 (PCM30C, PCM31C, V5 Uplink)
Generation and evaluation of the CRC4 code in time slot 0.
5.1.2 Transparent transport modes
A E1 port of the LEDE1 unit can be configured to one of the following trans-
parent transport modes:
• Transparent:
Transparent for clock and data.
The P12 signal has an unknown structure.
Cross connection and protection switching is established on the P12
(2 Mbit/s) traffic signal layer.
Please note:
The Transparent mode features clock transparent cross connections. That
means that the signal is in a plesiochronous phase relationship with the NE
timing source.
• Clock Master:
Transparent for data.
Unlike the Transparent mode, a clock master traffic signal is only cross
connected transparently in terms of its structure. The P12 output signal is
always resynchronised by the NE timing source. The input signal must be
synchronous to the output signal in order to avoid bit slips.
For details of the clock master mode, please refer to "1KHW002467
FOX61x TDM Services".
