Protective earth:
The marked lug or terminal should be connected to the building protective earth bus.
The function of protective earth does not serve the purpose of providing protection against electrical shock, but
instead enhances surge suppression on the DSL lines for installations where suitable bonding facilities exist.
The connector type is M3 machine screw.
Wetting Current:
Wetting current, also known as loop sealing current, is a low-level DC current applied to a loop for the specific
purpose of maintaining cable splice integrity by preventing the build-up of oxidation. There has the ability to sink the
source wetting current.
!
Warning! High Voltage. Do not open the housing.

4 Configuration with Console Port
This chapter will deal with the specifics of configuration and operation of this product via console port with terminal
emulation program. The configuration G.SHDSL NTU is performed via a menu-driven embedded software, using a
standard ASCII terminal or a PC running a terminal emulation application connected to the rear panel CONSOLE port.
Windows includes a terminal emulation program called HyperTerminal. Connect the appropriate communication
port from the PC to this device. After the physical connection is made, you are ready to configure this product. Make
sure you have connected the supplied RS-232C serial cable (DB9F to RJ-45 Plug) to the console port on the rear panel
on this product.
Run the terminal emulation program such as Hyper Terminal with the following setting:
Emulation: VT-100 compatible
Band rate: 115200, Data bits: 8, Parity: None, Stop Bits:1 , Flow Control: None
4.1 Login Procedure
At the start up screen, you will see:

Setup E1 Parameter, Line Code
The G.SHDSL NTU supports two different line codes: HDB3 and AMI.
HDB3 is the most popular and preferred line coding and is also the default setting.
AMI line coding is also selectable.
HDB3
In this line coding, the transmitter substitutes a deliberate bipolar violation when excessive
zeros in the data stream are detected. The receiver recognizes these special violations and
decodes them as zeros. This method enables the network to minimum pulse density
requirements. Unless AMI is required for your application, HDB3 should be used whenever
possible.
AMI
Alternate Mark Inversion defines a pulses as a “mark,” a binary one as, as opposed to a
zero. In an E1 network connection, signals are transmitted as a sequence of one and zero.
One is sent as pulse, and zero is sent as spaces, i.e. no pulse. Every other pulse is inverted
from the previous pulse in polarity, so that the signal can be effectively transmitted. This
means, however, that a long sequence of zero in data stream will cause problems, since
the NTU receiving the signal relies on the signal to recover the 2048kbps clock.
G.SHDSL NTU User Manual V0.03 84
Setup E1 Parameter, AIS
AIS (Alarm Indication Signal) is a method to inform the remote connection that there is a signal or sync problem with
the E1. AIS is only valid in framed mode E1, not in Unframed E1. The setting here of AIS enabled (on) or not (off) and
is for testing with AIS. When enabled, the E1 will transmit the AIS and it should be confirmed at the remote device
(AIS indication lit). After testing, please turn AIS back off.
For example 1: When STU-R E1 RX line is drop, STU-R sends the status to STU-C via EOC or command, and then
STU-C will send AIS (Alarm Indication Signal) to DTE while AIS function is enabled.
For example 2: When SHDSL connection drops, STU-R and STU-C both send AIS (Alarm Indication Signal) to DTE in
the same time while AIS function is enabled.
G.SHDSL NTU User Manual V0.03 85
