3 TECHNICAL DESCRIPTION
3.1 Application and general information about S-Access Etherlink_II devices
S-Access Etherlink_II devices represent xDSL modems (ITU-T G.991.2–G.shdsl and ITU-T
G.991.2 –G.shdsl.bis standards, TC-PAM line encoding). They are designed to organize high-
speed data communication channels over symmetric digital subscriber lines (DSLs) with the
transmission rates from 200 to 5704 kbit/s (with the step of 64 kbit/s). The TC-PAM (Trellis
Coded Pulse Amplitude Modulation) encoding used in these devices well combines such
characteristics as the transmission range, noise immunity and electromagnetic operability. The
number of levels (code states) in TC-PAM is increased up to 32 and a special error correction
mechanism is used. To increase the distance range by 2 or more times, regenerators can be
used.
The family of S-Access ETHERLINK_II includes devices with G.703 and Ethernet network
interfaces. Thus, the S-Access ETHERLINK_II equipment provides complex services which
allow one to transmit simultaneously voice and data as well as to construct TDM networks of
different topologies without using expensive interface converter, multiplexers and cross-connect
systems.
The devices of this family include network termination units (NTUs) and line termination units
(LTUs), which are installed at the customer (user) premises and the operator (provider)
premises, respectively. In addition, the devices of this family include regenerators. To organize
the “point-to-point” topology, the following schemes can be used: NTU – NTU, LTU –LTU or
NTU –LTU.
The devices can be powered from local DC sources. Regenerators and NTUs can be fed both
locally or remotely from LTUs. Figure 1.1 presents an example of organization of data
transmission systems with the help of modems of the S-Access Etherlink_II family. Other
variants of the usage of this equipment are also possible.

ETHERLINK_II LTU: S-Access ETHERLINK_II line termination unit;
ETHERLINK_II NTU: S-Access ETHERLINK_II network termination unit;
RGNo2: S-Access ETHERLINK_II regenerator.
The devices of this family have different mechanic designs: SubRack –a unit to be inserted into
a 19’’ AccessGain shelf; MiniRack –a 1U (44.5 mm) unit to be inserted into a 19’’ cabinet;
Stand Alone –a desktop unit; IP-67 –a unit in a water-proof plastic or silumin housing (class IP-
67); XCVR –a unit to be inserted into a hermetic steel housing.
The devices have the following possibilities for monitoring and management:
Local management and control of remote devices and regenerators –VT 100;
Local management and control of remote devices and regenerators –Telnet session;
Operation in complex networks under the unified management system –support of SNMP.

The use of the Flash memory as the ROM provides an easy upgrade of the software.
xDSL modems are powered from a grounded primary DC source (38 … 78 V) or remotely.
Modems are designed to be used in-doors under the following environmental conditions:
- temperature of ambient air –from -5 … +45°C;
- relative air humidity –from 5% … 85% at +25°C.
3.2 Main features of S-Access Etherlink_II devices
S-Access Etherlink_II modems represent the next generation of modems of the S-Access
Etherlink family and have the following features:
1. A new type of line encoding –TC-PAM32 (TC-PAM16 is also supported).
2. Duplex data transmission over one symmetrical pair at 5.7 Mbit/s.
3. Simultaneous transmission of the TDM traffic and Ethernet data.
4. The 802.1q protocol.
5. Different ways of system configuration (for example, remote configuration of devices via
Telnet).
6. Embedded WEB interface.
7. The SNMP protocol.
8. Possibility of storing several configurations in the device’s EEPROM in order to download
the previous settings of the system.
9. Two levels of system users: administrator and user, protected with passwords.
10. The use of the modern circuit printed boards, chips and components.
11. Extended reliability of the equipment.
3.3 PL and RL devices
From the mechanic point of view, the device represents a case made of shockproof polystyrene
to withstand harsh environmental conditions, the case containing the basic elements of the
device. The power supply unit represents an external power supply in the form of a plug.
The front panel contains the following connectors and LEDs:

3.5 Remote power supply, wetting current- supply and consumption modes
The wetting current supply and remote power supply modes can be changed by using jumpers
and the management PC.
3.5.1 Electrical safety regulations when using the remote power supply
Despite the safe voltage on each wire with respect to the ground (<120 Volts), the use the
remote power supply requires one to observe strictly the following rules:
When working with lines and the a junction box, the xDSL cable should be disconnected
from the device supplying the remote power;
The insulation of cable pairs, junctions (junction boxes, plinths, etc.) should correspond to
norms and standards of the network;
3.5.2 Compatibility of wetting current supply and remote power supply modes
The table of compatibility of the wetting current supply and remote power supply modes is
presented below.
The devices operating in pairs should be configured for mutual operation (“” –
compatible). The use of the mode «-» is not recommended because it may cause: high power
consumption, degradation of communication (communication stability), the use of additional
safety measures. The mode “incompatible” (inc) will not allow the devices to establish
communication (because in this case one or both devices will be de-energized).

3.5.3 Remote power feeding
Repeater devices can be configured to the local power supply and remote power supply modes
(LP/DP). The LP/DP modes are switched from one to another with the help of a toggle on the
rear panel of the device (see Figure 3.5).

3.5.4 Remote power Pass-through mode
It’s possible to feed more than one repeater in series from a LTU with a remote power source.
To provide the Pass-trough option, you have to put Jumpers to XM2, XM3, XM4 and XM5.
