3 CONFIGURATION / ACCESS
This chapter describes the different configuration access possibilities. The settings for the
Repeater are configurable via the V.24 monitor interface or via the EOC Service Channel with the
CONNECT xx command.
The following chapters refer to the xDSL configuration and doe’s not impact the E1 and Nx64
behavior.
3.1 Repeater xDSL interfaces
The xDSL Repeater has two xDSL interfaces: Network (N-side) xDSL interface (operates in slave
mode) and Customer (C-side) xDSL interface (operates in master mode). N-side interface operates
toward CO side while C-side transceiver works toward CP side. Are there one or more repeaters in
the xDSL link, there C-side and N-side interfaces must be connected by appreciated method.
Otherwise start-up might occur only for several segments of the link.
3.1.1 N-side / C-side xDSL interface operating modes
N-side xDSL interface operates in rate adaptation mode or in fixerate mode. The C-side takes over
the mode from the N-side
4 LED INDICATORS
Repeaters have two LED for power representation, link status- and test loop indication. The
following table shows the possible LED states.
Status Local (NE) LED Remote (FE) LED
Power failure off off

LOOP2 initialized green blinking don’t care

C-Side channelN-Side channel
On the 4 wire repeater its only possible to activate the LOOP2 from the master over the EOC
channel. You will find the LOOP2 command in the maintenance menu of the LTU.
6 PERFORMANCE MONITORING
The monitoring of the xDSL signal is typically used during the installation and maintenance. Its
possible to monitor the xDSL link in two different ways.
The G.826 error parameters are designed to observe xDSL links over longer time periods.
The NM is used to determine the residual S/N value before the DSL link becomes critical.
Please refer to the “NM” and “G826” monitor commands described in the “S-Access Monitor”
section.
7 POWER
7.1 Power inputs
The unit can be feeded over the following inputs:
• Molex connector
• DSL line (remotely feeded from the LTU)
7.2 Wetting current
The unit is able to handle the wetting current feature. Please use the jumper description table for
the desired settings.

8 MONITOR
8.1 General
The module can be connected to a terminal or a PC (with terminal emulation) in order to monitor
relevant events and to display additional information such as the signal quality of the xDSL link or
the G.826 error performance parameters. In addition, full system configuration and fault
localization can be done over the monitor interface
The terminal for monitoring should be VT100 compatible and configured as follows:
• 9600 baud, asynchronous
• 8 bits, no parity, one stop bit
• no new line on carriage return (i.e. no line feed on carriage return)
• flow control none
8.2 Structure & Organization
The structure and organization of the S-Access monitor is adapted to ITU-T Recommendation
M.3400 for TMNs with its five sub-sets.
Sub-set Short-form
Performance management PM
Fault and maintenance management FMM
Configuration management CM
Accounting management AM
Security management SM
A S-Access does neither support Accounting management nor Security management. AM and SM
are not in the monitor's main menu.
At any time, the <H> (“Help”) command shows and explains the available commands and their
parameters.
For details or a more precise explanation of a command type: H ´command´
The prompt on the screen consists of:
• a repeater indication (RR_)
• the repeater address indication
• the short form of the specified sub-set menu.
“RR_04_FMM>”.
Note:
Repeater address is calculated as repeater position (starting from CO side) in the xDSL
chain plus 2. Thus the repeater nearest to CO side has address 03, second one – 04, etc.
