3 TECHNICAL DESCRIPTION
3.1 General Information about S-Access Etherlink_IV
The S-Access Etherlink_IV SHDSL.bis Extended product family offers a broad range of products,
which are based on the latest SHDSL.bis standards (ITU-T G.991.2 & ETS TS 101 524), while also
being fully interoperable with all our existing SHDSL equipment (Etherlink1 & Etherlink_II). The SAccess Etherlink_IV supports TC-PAM16/32 and the new TC-PAM4/8/64/128 line coding. The
support of these line codes ensures compatibility with existing SHDSL equipment that is already
installed, in order to protect customer investments, while at the same time providing an upgrade
path to the newest DSL technologies.
SHDSL.bis Extended allows symmetrical data and voice transmission at speeds up to 15.2Mbps
over a single pair of copper. In addition, the S-Access Etherlink_IV modem range also supports DSL
channel bonding for up to 4 copper pairs in order to achieve speeds to 60.8Mbps! S-Access
Etherlink_IV SHDSL.bis Extended modems can provide up to 4 complete E1 interfaces, which
support framed and unframed services (G.703/G.704). An integrated 2 or 4 port Ethernet layer 2
managed switch with VLAN support (10/100BaseT) ensures connectivity to IP services. Beside of
E1 and Ethernet we have additional interfaces like Nx64 that can be configured to be a V.35, V.36,
X.21 or V.28 interface (cable selected). Also RS-232 and RS-485 (asynchrounous) are available.
This makes S-Access Etherlink_IV SHDSL.bis Extended modems a perfect solution for a wide range
of applications in which TDM and IP services need to be transmitted over copper wires.
Like all S-Access Etherlink products, the Etherlink_IV SHDSL.bis Extended modems family is based
on industrial components and is manufactured according to highest quality standards providing
additional value due to the extended temperature range and higher reliability.
The S-Access Etherlink_IV SHDSL.bis Extended product family consists of
LTU devices (Line Termination Units)

3.2.1 Remote Power Supply and Wetting Current
Etherlink_IV NTU devices do not support the wetting current termination like the LTU device. To
have wetting current means to remote power the NTU device. The remote power supply modes can
be changed by jumpers and the LP/DP switch (LP means local powering; DP means
distance/remote powering). Despite the safe voltage on each DSL copper wire with respect to the
ground (<120 Volts according to EN 60950), the use of the remote power supply has to be done
strictly according to the following rules:
When working with DSL copper lines make sure that the remote power is switched off.
The insulation of cable pairs, junctions (junction boxes, distribution frames, etc.) should be
checked against the remote power voltage (norms and standards of the network)
3.2.1.1 Compatibility of Remote Power and Wetting Current Supply Modes
Devices operating in pairs should be configured for mutual operation! The mode «» means
recommended and possible.
The use of the mode «-» is not recommended because it may cause high power consumption,
degradation of communication (communication stability), and additional safety measures.
The mode «inc» (incompatible) will not allow the devices to establish communication (because in
this case one or both devices will be de-energized).

3.2.2 Description of Etherlink_IV Interfaces
3.2.2.1 SHDSL Interface
The Etherlink_IV devices are available with 1, 2 or 4 SHDSL interfaces. The interfaces can operate
fully independent of each other as well as they can be combined to operate in multipair mode.
Therefore all independent SHDSL interfaces and groups of SHDSL interfaces (multipair mode) can
be configured separately from each other. The multipair mode, the reservation mode and the
automatic configuration detection mode naturally limit the independent working.
All SHDSL interfaces support plesiochronous data transmission. It means that reference clock
frequencies, which are used to clock data transmission, are transmitted together with the data in
different directions of one SHDSL link. The clock frequencies of different SHDSL channels are
completely independent if they do not operate in the multipair mode.
An SHDSL channel working in the independent mode can simultaneously transmit one or several E1
streams, Nx64 or RS-232/485 data and one WAN stream. E1This transmission is plesiochronous.
All E1 streams received by one SHDSL interface should use the same clock frequency in one
direction.

3.2.2.1.1 Master/Slave
To establish a connection, it is necessary that one transceiver side is configured as Master and the
other as Slave. In this case, the connection is controlled by the Master device.
3.2.2.1.2 Multipair Mode
If 2, 3 or 4 SHDSL channels are configured to operate in the multipair mode, they work at the same
clock frequency and line rate like one SHDSL channel with doubled, tripled or quadrupled
transmission capacity. Similarly to the independent channel, such a combined channel can
simultaneously transmit one or several E1 streams and one WAN stream. This transmission is also
plesiochronous. All E1 streams that are transmitted over one SHDSL interface should use the same
clock frequency per direction.
In multipair mode, one SHDSL channel serves as a “master” channel, while the other SHDSL
channels serve as “slave” channels. If the link in one channel fails, links in all other channels break
too and the procedure of connection/activation restarts.
The four-channel modems provide a possibility to organize pair-wise channels, i.e., these two twopair links will operate independently from each other. The main application for the multipair mode is
the increasing of the transmission range. In this case, some channels operate at low transmission
rates. In multipair mode some limitations are imposed on the Baserate parameter.

Table 3.5 Line settings per SHDSL interface, multipair mode.
The next figure shows an example of an Etherlink_IV device working in four-pair operation mode
(the <MULTIPAIR> command is used to configure multipair operation mode). Four SHDSL channels
are combined into one group. Through this multipair channel one E1 stream and Ethernet packets
are transmitted. This mode allows increasing the transmission range, compared to the use of only
one single SHDSL channel, because the data rate of each SHDSL channel is lower (the advantage
in the transmission range will depend on the cable parameters and noise immunity).

3.2.2.1.3 Reservation Mode
Reservation is provisioned for 2- and 4-channel S-Access Etherlink_IV devices. The main task of
reservation is to transmit the most important data even in the case of the failure of one or several
SHDSL connections. Reservation also takes care about an efficient bandwidth usage over all
SHDSL channels like the normal transmission modes.
Reservation will not guarantee a continuous transmission of important data in the case of a failure.
When one or several DSL connections fail, a short-term loss of Ethernet packet and E1 data can
occur.
SHDSL channels with successive numbers (example: DSL-1, DSL-2 or DSL-2, DSL-3, DSL-4) are
merged into a group of channels with reservation. For these merged channels, the traffic in the
SHDSL channels with the lowest numbers has higher priority than the traffic with higher numbers.
For example, DSL-1 has a higher priority than DSL-2, and DSL-2 has a higher priority than DSL-3. If
the communication in one or several SHDSL channels inside the reservation group is broken,
remaining working channels transmit the data of the failed high-priority channels. At any failure the
system always operates as if the low-priority channels failed.
Consider the reservation with two channels: DSL-1 and DSL-2 (DSL-1 has a higher priority
compared to DSL-2). If the DSL-2 channel fails, the DSL-1 channel continues to operate without any
changes. If the DSL-1 channel fails, the DSL- 2 channel transmits the data of the DSL- 1 channel.
Hence, the DSL-1 channel should transmit the high-priority data.
If the substitute channel has a lower transmission capacity than the main channel, the transmitted
data will be decreased. First, the volume of WAN data will be decreased up to 1 timeslot (TS,
64kbit/s), and then, the number of transmitted E1 timeslots will be decreased. If multiple E1 streams
are transmitted, the streams at the end of the list will be decreased (if E1-1, E1-2 are in the list, the
E1-2 stream will be deleted). First, timeslots with large numbers are deleted. However, there is an
exception for TS 16, which, if transmitted, will be deleted before or after TS 0.

Figure 3.7 Example of reservation
While for a two SHDSL channels system in case of a failure the substitution of channels is “trivial”, in
three and four SHDSL channels system different variants are possible. However, any system using
the reservation mode follows a strict logic in channel substitution. The next table illustrates the logic
of channel reservation with 2/3/4 SHDSL interfaces.
The table for four DSL channels is constructed based on the assumption that communication in one
channel is lost frequently, while communication in two channels occurs less frequently. Usually a
loss of communication occurs successively, i.e., the first channel fails and then the next channel
fails. The logic and rules for channel substitution are made to minimize the number of channel
switching (especially high-priority channels) to minimize the data losses.

Table 3.8 Examples of reservation of systems with two, three and four SHDSL channels
3.2.2.1.4 Automatic Configuration of a Link
S-Access Etherlink_IV devices support to configure the complete link in accordance with the MasterModem configuration. This mode is available for the following links:
Point-to-Point single-channel or multipair links
Point-to-Point multi-channel links with independent channels
Star-topology multichannel links
Point-to-Point two-channel two-pair links
Star-topology two-pair links
Links with regenerators
Note: Automatic configuration of link reservation is not supported.
When the automatic configuration is used, the Slave-Modems and Regenerators receive nearly all
configuration parameters for DSL and all other interfaces (like E1) through the link from the MasterModem. In a majority of cases they require just a minimum configuration, what helps not to duplicate
manually the configurations to all other devices in the link. Configurations like the number of
transmitted E1 timeslots over DSL, CRC4 and E1 (G703/4) modes do not have to be configured on
all devices because they are received automatically through the link.
The system of automatic configuration operates the following way:
The CP side (Slave) automatically adjusts configuration according to the stream structure
received from the CO side (Master), not to cause permanent losses of user data.
If the CP side (Slave) cannot adjust correspondingly, it displays a RCONF alarm and sends a
message to the remote terminal device (Master). If configurations of terminal devices (Master
and Slave) do not coincide, the RCONF alarm is displayed. RCONF means a remote urgent
alarm.
The link is adjusted in the channel structure in the direction from the Master- to the Slave-Modem:
The stream structure is configured on the Master-Modem device.
If there is any Regenerator in the link, it receives this structure and configures itself according
to it.
Also a next Regenerator receives the structure from the previous Regenerator and performs
configuration according to it.
Page 22
DT Etherlink IV User Manual
- 22 -
The Slave-Modem receives the stream structure from the last Regenerator in the link and also
performs configuration
When the Slave-Modem receives configuration, it distributes the received E1 streams
information to its E1 ports. If the number of ports is not enough, it displays the RCONF alarm
and does not change the configuration of the E1 streams. Also if the E1 streams are not
distributed, the Slave-Modem receives the configurations of WAN. Therefore, the integrity of
the Ethernet link is supported.
The RCONF alarm (displayed by the <ALARM> command) means that the local and remote
equipment have incompatible configurations.
The RCONF alarm is automatically not displayed if a DSL link, in which it was detected, fails.
If the device operates in the CA mode (automatic configuration of a link), the alarm is not
displayed when the device finally adjusts to the CO side (Master).
Figure. 3.9 Automatic configuration, 4x E1 and Ethernet are transmitted over one SHDSL link
Figure 3.10 Automatic configuration Star-topology
A more complex case is the independent two-channel connection: two E1 streams and Ethernet
packets are transmitted in the first channel and the second channel. The Slave-Modem determines
the order of E1 interfaces for the streams from each DSL link only when the communication in both
links is established.

3.2.2.2 E1 Interface (G.703/704)
3.2.2.2.1 Framed and Unframed E1
The Etherlink_IV product family supports transmission of framed and unframed E1 interfaces.
In unframed (transparent) mode, the E1 data is transmitted over the SHDSL without any changes.
In framed mode (framing according to ITU-T G.704), the E1 data is processed by the onboard E1
framer. In this case, 1-32 timeslots per E1 stream can be transmitted over the SHDSL line.
3.2.2.2.2 CRC4 (Cyclic Redundancy Check)
The CRC4 mode enables the error performance monitoring of the E1 network interface with the help
of a cyclic redundancy check.
If the mode is enabled, the modem synchronizes with CRC4 sub-multiframes at the E1 output and
displays information about CRC errors. In this case the modem regenerates E1 CRC4 submultiframes and checksum words in the outgoing E1 stream.
If the mode is disabled, the modem transmits transparently CRC4 sub-multiframes and checksum
words if the generation of the zero time slot is not activated. If the TS0GEN mode is activated, the
zero time slot is generated without CRC4 sub-multiframes and checksum words.
3.2.2.2.3 AIS Generation (Alarm Indication Signal)
If this mode is enabled, AIS will be transmitted to the E1 side under the following conditions:
the loss of the line signal from the remote device or loss of frame alignment on the DSL side
the remote device receives an AIS over E1 interface, which is configured to transmit data from
E1 to DSL. This mode is enabled only if the AIS detection mode is enabled on the remote
device (see below). If multiple E1 streams are transmitted the AIS generation and detection
are independent per E1 stream.
WARNING
IF THE AIS GENERATION MODE IS DISABLED, THE SIGNAL AT THE
OUTPUT OF THE E1 INTERFACE WILL BE ABSENT WHEN LOSING
COMMUNICATION IN THE DSL LINE (EXCEPT FOR TIME SLOTS OF THIS
INTERFACE DEDICATED TO CARRY ETHERNET DATA)
IF SOME TIMESLOTS OF AN E1 INTERFACE ARE USED TO TRANSMIT
ETHERNET DATA, AIS WILL NOT BE GENERATED FOR THIS INTERFACE.
Page 24
DT Etherlink IV User Manual
- 24 -
3.2.2.2.5 AIS Detection
If this mode is enabled, the reception of an AIS through the E1 interface will cause the following:
a non-urgent alarm will appear
AIS will be transmitted to the remote device of the DSL
WARNING
IT IS RECOMMENDED TO ENABLE THE AIS DETECTION AND AIS
GENERATION MODES FOR ALL E1 NETWORK INTERFACES.
3.2.2.2.6 Е1 Clock Modes
The Etherlink_IV product family has different possibilities to synchronize E1 interfaces. Usually the
E1 interface takes the E1-clock from the E1-input and transmits it through the SHDSL link to the E1output (plesiochronous). But we also support external clocking, internal clocking and clocking
priorities.
Figure 3.12. Е1 clock modes
From E1 network interface side to SHDSL line side the following clock sources can serve as
reference timing signals:
1. External clock generator (EXTERNAL) (inside subrack/minirack/UTT4).
2. Clocking from the first E1 input stream (E1-1) (if available).
3. Clocking from the second E1 input stream (E1-2) (if available).
4. Clocking from the third E1 input stream (E1-3) (if available).
5. Clocking from the forth E1 input stream (E1-4) (if available).
6. Clocking from the internal generator (INTERNAL).
With the SETCLOCK command, the user can configure the priority levels for the clock sources. The
device automatically switches to the clock source with the highest priority under conditions that
synchronization in this mode is possible.
EXTERNAL means a synchronization from an external clock generator corresponding to the
recommendation ITU-T G.703.10. If the input signal of the external clock is lost, the device switches
to another clock source according the priority level. Using the external clock in synchronization
priorities, this external clock should have the highest priority. If the external clock generator is
absent, it should not be included in the priority list.

E1-1, E1-2, E1-3 and E1-4 mean synchronization from one of the input E1 stream. If the E1 stream,
which serves as a clock, is lost, the device switches to another clock according to the priority level.
INTERNAL means synchronization from an internal clock source. This clock source should be the
last one in the priority list (but in the absence of any other clock source, for example, when only
Ethernet data are transmitted, this source can be the primary and the only one).
Switching between clock sources occurs within 100 ms, after loosing synchronization.
3.2.2.3 Nx64 and RS-232/RS-485 Interfaces
The Etherlink product family can be equipped with a wide range of modular and exchangeable
daughtercards with different interfaces. In this manual we describe the most important three cards.
The first card supports Nx64 interfaces (V.35, V.36, X.21, V.28), the second card supports
asynchronous RS-232 interfaces and the third supports asynchronous RS-485.
Nx64 interfaces:
V.35, Speed 64…8192 kbps
V.36 (with termination), Speed 64…8192 kbps
X.21 (with termination), Speed 64…8192 kbps
V.28 (synchronous), Speed 64…192 kbps
Interface type is cable selected. You can use the command EXTRATE [N] (N=1…128) to set the
data rate (N*64 kbps).
RS-232 interface:
RS-232, Speed 1200-256000 bps
number of data bits: 5…8
number of stop bits:1, 1.5 or 2
parity: odd/even/odd/mark/space
You can use the command EXTRATE [N] to set the baud rate (N is baudrate, for instance 9600).
The command RSFORMAT [format] is used to set the data format (example of format: 8N1).
RS-485 interface:
RS485, Speed 1200-256000 bps
number of data bits: 5…8
number of stop bits:1, 1.5 or 2
parity: odd/even/odd/mark/space
You can use the command EXTRATE [N] to set the baud rate (N is baudrate, for instance 9600).
The command RSFORMAT [format] is used to set the data format (example of format: 8N1). The
RS485 interface supports half- and full-duplex operation configurable by the command RSDUPLEX
[F/H].
3.2.2.3.1 Nx64 Clocking Modes
Nx64 clocking modes can be selected by using the command EXTCLOCK [SRC] [DIR]. The SRC
argument sets one of 3 possible clock modes for the transmit and receive clocks (signal number 114
(TX clock) and 115 (RX Clock)):
NORMAL (DSL) both clocks are derived from the receiving DSL stream
INT (internal) both clocks are generated from the internal generator signal
TTC (external) clock for signal number 115 is derived from the terminal transmit clock input
(signal number 113)
The DIR argument sets the transmit clock direction:
CO (codirectional): Transmit clock and transmit data have same directions, i.e. both are inputs
to the modem at signal number 113 (clock) and 103 (data). In case of RX mode (see above)
the whole TX path is clocked by this clock, while in other modes data coming to TX input
(signal number 103) is put into FIFO using the clock from line 113 and get out from FIFO by
clock defined by SRC.
Page 26
DT Etherlink IV User Manual
- 26 -
CONTRA (contradirectional): Transmit clock and transmit data have opposite directions, i.e.
transmit clock is an output from the modem at signal number 114 and transmit data is an input
to the modem at signal number 103.
In combination with the command SETCLOCK (units with Nx64 interface have the possibility to set
the clock source to the SHDSL line side as Nx64 clock (parameter “V35” of SETCLOCK
command)), it is possible to realise different clock schemes. The following table shows different

3.2.2.3.2 Automatic V.54 Loops
The system supports only a local V.54 loop managed by the line 141. The support of the V.54 loops
is software programmable. You can use the command AUTOLOOP to adjust automatic loop
reaction: Lines 140 and 142 are not supported by the system.
3.2.2.4 Ethernet Interface
The Ethernet interfaces of all S-Access Etherlink_IV devices fulfil the standard IEEE 802.3 and
support the Port (PBVLAN command) and Tag (VLAN command) based VLAN protocol (Virtual
Local Area Network – IEEE 802.1Q). A virtual network represents a group of network nodes, whose
traffic, including the broadcast traffic, is completely isolated from other network nodes. The
organization of virtual networks usually decreases the load in the network, because the broadcast
traffic will be transmitted not to the entire network but to members of the VLAN sender. Due to the
fact that the members of different VLANs can exchange information via a router, which allows a
controlled traffic, the use of VLAN technology provides a high level of security. In addition, any
changes in the network structure are simplified because instead of configuring the work station to
which the modem is connected you only have to configure the modem port.
To construct VLAN networks and to provide the priority in the data transmission, an extended
Ethernet frame is used, which contains an additional VLAN tag of 2 bytes length. The tag includes
the number of the VLAN to which the packet belongs and its priority level.
Some types of traffic (real-time video, voice or IP traffic) should be sent inside the network without
any delays. To provide the necessary quality of this traffic, the Etherlink_IV devices support Ethernet
traffic priority according to the standard protocol IEEE 802.1P (so-called QoS, Quality of Service). It
means to analyze the header content of each Ethernet frame to get information about the necessary
priority of this application. The internal switch places this data to the corresponding queue of the
output port. The Etherlink_IV equipment supports two priority queues when sending packets – a
high and low priority queue. According to it, all Ethernet traffic can be divided into high priority
groups (for example VoIP traffic or control and management channels) and low priority groups (for
example LAN1 and LAN2).
The Ethernet traffic between all network interfaces of the device is distributed by the internal
Ethernet switch (see next figure). In Etherlink_IV devices four types of network interfaces exist:
Ethernet interfaces (external connector on the front panel, and back plane connector)
SHDSL interfaces (when the device is properly configured)
E1 interfaces (when the device is properly configured)
Virtual management port (Telnet session)
The number of E1 and SHDSL interfaces depends on the model of the Etherlink_IV family. The
choice of the interface (DSL or E1), which will be mapped to the corresponding WAN interface is
performed by the <PAYLOAD> and <WANTS> command.
Page 28
DT Etherlink IV User Manual
- 28 -
Figure 3.14 Internal Switch (ETH5 is not available for NTU devices)
For single-channel modems the DSL channel is strictly mapped to WAN1, while the E1 interface is
strictly mapped on WAN2.
Figure 3.15 Internal Switch for single-channel devices (SA-RC-2DSL_2E1-4Eth-RP)
A group of LANx Ports (Ethernet interface) means the LAN port connector on the front panel or
backplane that can serve as a Trunk port, Access port or Mixed port.
The Trunk port is a port where all present packets have the VLAN format, namely, the Ethernet
frame with a header, determining the number of the VLAN and QoS. In Trunk mode, only tagged
frames pass into and out of LANx port, frames are allowed to pass on per-VLAN basis. This means
that special equipment supporting VLAN is connected to the Trunk port. A PC with a standard
network interface card cannot be connected to the Trunk port.
The Access port is a port where all present packets have a standard Ethernet format (without the
additional two bytes for the header). It means that only untagged frames pass into (ingress) and out
of (egress) any LANx port. On ingress, frames are assigned with a default VLAN tag (configured by
VID and QoS commands). On egress, only frames with VLAN equal to the default VLAN of the port
are allowed, and this tag is removed. A PC with a standard network interface card can be connected
to the Access port.
Page 29
DT Etherlink IV User Manual
- 29 -
The Mixed port is a port where tagged and untagged traffic is allowed. However, on ingress, a
default VLAN tag is assigned to untagged traffic (configured by QOS and VLAN commands), so that
all frames in the system are actually tagged. On egress frames with VLAN equal to the default VLAN
(configured with VLAN command), exit the port untagged, while to all other VLANs apply pass/block
rules set by the ALLOW command.

Table 3.7 Access, Trunk and Mixed Mode
Etherlink_IV devices always transmit Ethernet packets over DSL or E1 interfaces with the VLAN
format. It means that data packets coming from Access ports are first transformed into Ethernet
packets with VLAN format (adding standard VLAN number and QoS priority level) and after this
transmitted over any line interface.
There is a special case when having the same MAC address on different VLANs and PBVLANs.
Normally, there should not be two devices on the network sharing the same VLAN. But IEEE 802.1Q
VLANs as well as port-based VLANs allow creating separate logical networks on one physical
network. Thus, in different VLANs or PBVLANs there could be devices sharing the same MAC
address. On Etherlink_IV, however, there is a hardware limitation preventing all VLAN+PBVLAN
combinations from having different address databases, and therefore, allowing same MAC address
to be used on all VLAN&PBVLAN combinations is possible in the modem configuration. But,
knowing which configurations are valid will allow using modems in all really vital configurations.
There are two rules.
1. For separately managed VLANs 1-8. Each VLAN has its own MAC address table, and thus
device with MAC address ABC in each of these 8 VLANs will not conflict with any device with
MAC address ABC in any other VLAN. But the limitation here is the use of port-based VLANs.
MAC address database is shared among all PBVLANs for VLAN1-8. Therefore a device with
MAC address XYZ, VLAN1, PBVLAN A, will conflict with device with MAC address XYZ, VLAN1,
PBVLAN B.
2. For all other VLANs. Here, every PBVLAN has its own MAC address table, but different VLANs
on one PBVLAN share the same database. A device with the MAC address XYZ, VLAN(any
other), PBVLAN A, will not conflict with a device having the MAC address XYZ, VLAN(any other),
PBVLAN B. But the device with the MAC address ABC, VLAN(any other), PBVLAN A, will
conflict with the device having the MAC address ABC, VLAN(any other+1), PBVLAN A.

Table 3.9 Same MAC address on different VLANs and PBVLANs
In addition, every unit has a table of static MAC addresses (up to 8 addresses) for connected
devices, so that each device can have a VLAN number and a QoS priority level (this is a table of
special MAC addresses). If a packet is received from the Access port and the MAC address of the
packet sender is inside this table, a header with the necessary VLAN number and the QoS priority
will be assigned to this packet before transmitting it to the Trunk port. Otherwise, a default VLAN
number and QoS priority will be assigned to the packet.
A group of DSL ports (WAN1–WAN4) (SHDSL interface) means that Ethernet data can be
mapped onto specified timeslots (64kbit/s) on the SHDSL interface by using the internal switch. In
this case, this port always serves as a Trunk port. Any data received from Access/Mixed ports are
first transformed into Ethernet packets with VLAN format and then transmitted over the SHDSL
interface.
A group of E1 ports (WAN1–WAN4) (E1 interface) means that Ethernet data can be mapped onto
specified timeslots (64kbit/s) on the E1 interface by using the internal switch. In this case, this port
always serves as a Trunk port.
A virtual management port (INT) (Virtual management port) is an internal device management
program. The IP-address of this device is the logical address of the management program. For
example, to open a session for managing a remote device, the IP-address of this device should be
specified in the Telnet program. At the physical layer, the MAC address of the device is also the
management program address, which is inside the Ethernet frame.
Note: As a rule the data of the management port have the highest priority (example, QoS = 7).
3.2.2.5 Rapid Spanning Tree Protocol
The system supports Rapid Spanning Tree Protocol (RSTP) according to IEEE 801.1d 2004
recommendation. All available Ethernet ports as well as all available WAN interfaces could
participate in RSTP construction. A WAN interface could be configured to carry Ethernet data over
DSL line or over E1 interface. If several DSL links or E1 interfaces are combined into MULTIWAN,
this MWAN will participate in RSTP construction too.
The RSTP itself is a protocol used for dynamic link switching in networks with ring topology. The ring
topology improves reliability of data networks; nevertheless Ethernet networks must have only one
active path between any of two nodes to prevent packet loop. Ethernet switches with enabled RSTP
Page 31
DT Etherlink IV User Manual
- 31 -
detect paths availability in a ring and quickly select active path, discarding other paths. All RSTPenabled devices exchange information about topology change in so-called BPDU packets.
Root Bridge
One switch in a RSTP-enabled network must act as Root Bridge. Root Bridge selection will be done
automatically according to Bridge ID – a unique ID that each member of RSTP network has. Bridge
ID is a combination of Switch MAC address and Bridge Priority. Switch with smallest Bridge Priority
will act as Root Bridge. If two or more switches have same priority, Switch with less MAC address
will become Root Bridge.
Port Roles
After Root Bridge has been selected, other switches define their ports role. The port that has the
shortest path to Root Bridge will become Root Port. The opposite port on the other switch will
become Designated Port. The Root Bridge has Designated Ports only, while other switches have
one Root port and could have Designated Port connected to other switches
A Root and Designated ports are active, they learn and forward packets. Other ports have blocking
state. They could act as Alternate port or as Backup port. Please take a look to a picture below:
Figure 3.16 Port role definition in RSTP.
When a failure appears on a network, an alternative path will be selected and port roles will be
changed. Please take a look to a picture below:

3.2.3 An Integrated Switch of 64-kbit/s Time Slots
3.2.3.1 E1 Transmission Mode (only E1 Time Slots)
In this mode, only time slots of E1 data streams are transmitted over SHDSL lines according to ITUT Rec. G.991.2.
Table 3.10 Comparison of SHDSL data rate and number of possible time slots of one E1 stream
3.2.3.2 E1, Nx64/RS-232/RS-485 and Ethernet Simultaneous Transmission Mode
The system supports simultaneous transmission of E1 time slots, Nx64/RS-232/RS-485 data and
Ethernet data (from the ports WAN1, WAN2, WAN3, WAN4, and the internal Ethernet switch) into
an SHDSL line. This mode means time slot multiplexing from E1, Nx64/RS-232/RS-485 and
Ethernet network interface into the SHDSL line. The distribution of SHDSL time slots is performed
as follows:
time slots of the first E1, chosen for transmission in the SHDSL line interface in the ascending
order, are transmitted in time slots from 0 to m1-1
time slots of the second E1, chosen for transmission in the SHDSL line interface in the
ascending order, are transmitted in time slots from m1 to m1+m2-1
Nx64/RS-232/RS-485 data is transmitted in time slots from m1+m2 to m1+m2+m3-1
Ethernet data is transmitted in time slots from m1+m2+m3 to n-1
Here
n is the total number of transmitted SHDSL time slots
m1 is the number of time slots from the first E1 selected for transmission into SHDSL
m2 is the number of time slots from the second E1 selected for transmission into SHDSL
m3 is the numer of time slots required for Nx64/RS-232/RS-485 data
Note: A part of time slots of an E1 interface can be used to transmit data from the WAN2 port of the
internal Ethernet switch.

3.2.4 Test Loops
The possibility to activate test loops on E1 or SHDSL line interface simplifies the device start-andadjustment.
Figure 3.6. Test loops
Test loops can be activated for the Master and Slave devices as well as for the Regenerator.
The LOOP1 ON/OFF N command is used to activate/deactivate LOOP1, where N is the number of
the network interface.
LOOP2 M:N, where M is the number of the line interface and N is the number of the Regenerator,
can be activated only remotely. This command allows activating remotely a loop back to the
device, from which the command was sent. It means that if LOOP2 is activated remotely by the

versa.
WARNING
WHEN ACTIVATING LOOP2 UNDER CONDITIONS THAT SHDSL IS USED
TO TRANSMIT ETHERNET DATA, IT IS NECESSARY THAT THE DEVICE IS
DISCONNECTED FROM THE ETHERNET NETWORK!
3.2.4.1 Analogue Loop back
During the analogue loop back test, the SHDSL transceiver receives the transmitted signal from its
own transmitter. The analogue loop back function (the STARTAL command is used to activate the
analogue loop back) is used to test the equipment itself.
The analogue loop back causes a non-urgent alarm of the local unit and an urgent alarm of the
remote unit.
WARNING
TO PERFORM THE ANALOG LOOPBACK, THE CABLE SHOULD BE
DISCONNECTED FROM THE UNIT!
3.2.4.2 Performance Monitoring
The transmission performance of a link can be monitored in two different ways. The signal quality is
typically used during installation and maintenance procedures, whereas the G.826 error
performance parameters are used for long term evaluation of operating links and during acceptance
testing.
The Noise Margin (NM) provides qualitative performance information of a specific link. The NM
command is used to activate this test. This parameter is calculated according to ITU-T G.991.2 and
is an efficient tool for determining the qualitative performance of an SHDSL link.
During acceptance testing, it is recommended to set the line rate or choose cable pairs (at a fixed
line rate) so that the NM value is no less that 6 dB.
An NM of 0dB in the presence of a Gaussian noise would yield an expected Bit-Error-Ratio of
10-7.
3.2.4.3 G.826 Performance Monitoring
The error performance monitoring of a SHDSL link is performed according to ITU-T Rec. G.704. The
evaluation of the G.826 error performance parameters is based on CRC (Cyclic Redundancy Check)
error detection. CRC generation and detection are performed separately for the E1 interfaces and
SHDSL interfaces.
Page 35
DT Etherlink IV User Manual
- 35 -
Figure 3.20 G.826 performance evaluation
On the E1 side, four CRC4 check bits are generated per sub-multiframe (SMF) and compared with
the corresponding bits of the next SMF. If they do not match, the CRC4 error counter is
incremented.
On the SHDSL side, six CRC6 check bits are generated per SHDSL frame. CRC6 errors are used
by the software to count the block errors of the SHDSL channel and to evaluate its error
performance according to ITU-T Rec. G.826.
For the E1 interface, calculations according to G.826 are only possible in the framed mode
according to G.704 with the CRC4 option enabled. In the framed mode with the CRC4 option
disabled, only FAS errors are detected.
The estimation of a bit error rate is not within the scope of G.826 calculations.
3.2.5 BERT Test
We suggest BERT testing in the following way: Switch on Loop2 on the remote unit (slave) and
setup the BERT on the master unit.

To display an urgent alarm has the highest priority (overwrite a non-urgent alarm).
3.4 Management of Etherlink_IV Devices
Etherlink_IV devices have integrated management and diagnostic functionality. The access to this
functionality is done by:
Connecting the Local Craft Terminal (LCT) or MONITOR interface (RS-232 or USB interface)
to any management terminal (PC with VT100 terminal, for example the application HyperTerminal).
Connecting the local Ethernet interface to any management terminal (PC with Ethernet
network card). In this case you access with a Telnet session or you use the WEB interface to
display some statistics. Also the SNMP (Simple Network Management Protocol) is integrated.
The management and diagnostic functionality is used to configure the devices and to receive
additional information like G.826 parameters or any G.SHDSL link quality.
3.4.1 Management by Local Craft Terminal or MONITOR Interface (RS-232, USB )
Etherlink_IV NTU devices have a standard based RS-232 and USB interface for connecting any
management terminal. The corresponding connector can be found either on the front or the rear
panel of the devices.
Monitor, Local Craft Terminal DB9, RS-232
Monitor, Local Craft Terminal USB
To use the USB interface as local craft terminal, you need to download and install the following
driver http://www.S-Access.ch/extranetfiles/Software/Etherlink_IV_USB_Driver.zip. This is an USB
to serial driver and allow to have a COM port over USB.

3.4.2 Management by Ethernet Interface
3.4.2.1 Telnet
The TELNET (TELecommunication NETwork) access is made through the Ethernet network. With
any computer and a program with the Telnet protocol Etherlink_IV devices can be fully managed.
After opening the Telnet session, there is a user authentication: “admin” users, who can change
configurations and “user” users who can only view parameters and statistics. Initially passwords are
empty. In this case the authentication is not performed and users automatically have the
administrator rights. Only “admin” users can set passwords for both types of users. If authentication
is successful, the modem main menu is displayed. If authentication fails, it can be repeated up to
three times, and after it the connection breaks.
Example: The management through a Telnet session can be activated by a standard command on
any Windows computer: telnet <IP-address>
If no symbols are received by the modem over the telnet connection within 5 minutes, this session
breaks. And with correct configuration, every SHDSL modem with an IP address can be reached; it
does not matter if near end, far end or repeater.
3.4.2.2 WEB
The WEB interface is used to display statistics when the Etherlink_IV SHDSL modems are
connected to the management computer via the Ethernet interface. Any WEB browser can be used
to access the WEB interface. To display the statistics you should enter the command:
http://X.X.X.X/ on the WEB browser. (X.X.X.X is the IP-address of the modem). After the
connection is established, the active window of the WEB browser displays the following alarms and
statistics (there are several pages available):
Figure 3.7 WEB interface – “Etherlink_IV Alarms”
If you chose the configuration menu you have some tabs for the configuration. Please check under
the command description if you need some explanation about any setting. If you have changed the
configuration you have to press the “Save” button. The configuration is then active and if you like to
Page 40

have the configuration stored you have to change to the tab “Device Management” and press the
“Confirm” button.
Figure 3.8 WEB interface – “Etherlink_IV Configuration”
Figure 3.9 WEB interface – “Etherlink_IV Configuration-Device Management”
All tables are displayed dynamically. The parameters in the tables are refreshed every 5 seconds.
Click the button in the left part of the window of the WEB browser to display the necessary table.
The software version is also displayed in the left part of the window. The WEB interface of the
SHDSL line card has following windows: Alarms, DSL Status, DSL Statistics (G.826), TCP/IP &
ICMP Statistics, Net (WAN) Statistics, Command Reference.

3.4.2.3 SNMP
The management with SNMP (Simple Network Management Protocol) is used to monitor the status,
to configure and to manage any network equipment. The big advantage of SNMP is usually the
immediate unasked information (TRAP) if something is not running correct. Etherlink_IV DSL
modems support SNMP v1. The management control computer should have a special SNMP
program installed.
The following management information bases (MIBs) are supported:
RFC1213-MIB, a standard MIB for all devices, supporting MIB II and described in RFC-
1213, is fully supported
IF-MIB, MIB descriptions of interfaces, described in RFC-2863, is fully supported
DS1-MIB, MIB describing E1 streams, RFC-2495, is partially supported
Traps are sent by the device into two addresses. The following traps are supported:
cold Start (RFC1215)
authentication Failure (RFC1215)
linkUp (RFC1213-MIB, IF-MIB)
linkDown (RFC1213-MIB, IF-MIB)
dsx1LineStatusChange (DS1-MIB)
An SNMP agent should be installed to work with SNMP. The COMMUNITY command (configuration
of the community parameter of SNMP messages) and the TRAPIP command (configuration of IPaddresses for traps) are used to configure the SNMP agent. The IP-address and the other network
configurations of the SNMP agent coincide with network configurations of the device (see SETIP,
NETMASK, GATEWAY commands and the NET sub-menu).
Using the variables described in the MIB the following actions can be performed:
view general information about the device
monitor the general status of the device (presence of alarms)
reboot the device
configure the device, control configurations (use, acknowledge), backup and restore
configurations
view and clear G.826 statistics for E1 and DSL
view alarm status
Every variable of the S-Access-MIB, as well as of all other MIB files have a detailed description in
the MIB file itself.
The MIB can be received from S-Access GMBH – support@s-access.ch:

4.2 Etherlink_IV Software
Every Etherlink_IV device stores up to two software versions in the memory (EEPROM): one
unchangeable software (standby software No.1) and one upgradeable software (software No.2).
Two versions are necessary to prevent any device failure due to downloading of faulty or damaged
software or due to hardware failure during downloading of the new software.
During downloading, the new software overwrites the upgradeable software. If the new software
downloading via X-modem is successful, a message appears that the modem should be restarted to
start operating under the new software. After the restart, i.e., when the new version of the upgraded
software is started for the first time, the operator should confirm the downloaded software. After
confirmation, this software becomes unchangeable. If downloading was interrupted or there was a
failure in the data transmission, a message is displayed. In this case, if the data has already been
partially downloaded into the modem and the upgradeable software is damaged, the unchangeable
software will be used to start the modem (please repeat the downloading of the software).
By default, the upgradeable software is the basic one, if it was confirmed. If the upgradeable
software was not confirmed after the first start or it was damaged (invalid data format, incorrect
checksum), the standby software is loaded.
4.3 Configuration and Application Storage
The whole system stores four configurations: running configuration, startup configuration, new
configuration and backup configuration.
The running configuration contains all configuration values guarantee the current operation of the
device. If two modems have the same version of the software and the same running configuration
they should operate equally. The running configuration is stored in the RAM of the device. The
current parameters determine the operation until the next restart or any actions on the running
configuration (storage and etc.). During initialization the initial parameters of the running
configuration are loaded from the startup configuration.
The startup configuration contains all configuration values which will be used to configure the
device after its restart. The startup configuration is stored in EEPROM and is used to initialize the
running configuration during the system start-up.
The new configuration stores changes in configuration parameters combined into groups of
parameters that require a confirmation of changes (i.e., this configuration stores setting, which
should be confirmed after being changed, for example, IP-address of the device). The new
configuration is stored in the device RAM. After setting all necessary changes from the group, the
system administrator confirms changes in the group, and values belonging to this group are written
from the new configuration into the running one. In this case, the simultaneous application of all
setting in the group is guaranteed.
The backup configuration is a backup of the current configuration. The backup configuration is
stored in the EEPROM. During the configuration restoration, values from the backup configuration
are copied to the startup configuration.
Page 45
DT Etherlink IV User Manual
- 45 -
All configuration parameters are divided into three groups according to their application:
configuration parameters applied after the restart
configuration parameters applied instantly
configuration parameters requiring a confirmation
Configuration changes, which are used after the restart, are written into the startup configuration, but
before doing the restart the device continues working according to its “old” configuration. During the
device restart, the values of these configurations are copied from the startup configuration into the
running one and thus become valid.
Figure 4.1 Operations of the configuration parameters after the restart
Configuration changes, which are used instantly, are written into the running, startup and new
configuration, and the device continues working according to these configurations.
Figure 4.2 Operations of the configuration parameters with the instant application
Changes in configurations, which are part of a group of configurations that require a confirmation,
are initially written into the new configuration. After the administrator confirms changes in the group
of configurations, this group is copied from the new configuration into the running configuration and
the device starts working according to these configurations. The administrator also can confirm
changes in all groups. After the received running configuration is checked, the administrator can

confirm this configuration. In this case, changes in all groups are copied from the running
configuration into the startup configuration.
Figure 4.3 Operations of configuration parameters that should be confirmed
4.4 Groups of Commands Requiring Confirmation
In Etherlink_IV devices the following four groups of parameters require a confirmation: LINE, NET,
VLAN and SNMP. Changing configurations of each group use some special commands. The APPLY
<name of the group> command is used to apply changes in configurations performed in a group.
After this, the unit applies changes in configurations. If groups LINE, NET, VLAN were changed not
in the local management session via the RS-232 interface but via Telnet the management session
breaks and the unit waits for the second connection within 5 minutes (for the LINE group – 30
minutes). If the LINE group was changed remotely (using the CONNECT command), the unit waits
for the second connection within 30 minutes. If within this time the operator did not enter the modem
menu, the changed parameters are read from the startup configuration of the unit. Therefore, it is
possible to restore the configurations of the unit. A “successful” configuration can become the
startup configuration by using the CONFIRM command.
4.5 Command Syntax
The following rules are used to describe commands:

Applying configuration changes in group LINE to running configuration
4.6.2.3 <CONNECT N:1..13/R> Command
The <CONNECT N:1..13/R> commands initialize the management of the remote device. The
parameter N sets the number of the SHDSL channel, over which the connection is initialized. In
single-channel systems the parameter N can be absent.
Notes:
1. The <CONNECT R> command in the Slave mode is only available if the Master
device can be configured locally at this instant.
2. The <CONNECT N> (N=1..13) command initializes the management of the remote
regenerator. The <CONNECT N> command is only available in the Master mode.
3. This command is not provisioned for regenerators.
4. If the channel of remote management is blocked (for example, a message or a
table are not displayed completely), press Enter.
4.6.2.4 <LINK [SN/00/FE]> Command
The < LINK [SN/00/FE]> command establishes connection to specified unit over the backplane.
SN - Specifies the slot number of a subrack unit to connect with. If the backplane is busy or if the
specified subrack slot is free (or no response in 1.5 first seconds) the "LINK ERROR" message
will be issued by the unit. For subrack units SN should not be 00.
00 - (double zero) Switches on the Monitor (Local Craft Terminal) connector control mode for
Minirack and standalone units. In this mode all typed characters will be translated to the Monitor
connector.

The INT interface (internal) counters are a special case. It's in and out directions are reversed in
comparison to any other interface. For example, if frame enters LAN1 and leaves modem
through WAN1, it will be counted as in for LAN1 and out for WAN1. But if frame enters LAN1 and is
forwarded to INT, it will be counted as in by both LAN1 and INT.

After typing “3” in the main menu and pressing <enter>, the following message is displayed:
Configuration management activated
Enter 'M' to return to MAIN, or 'H' for HELP information
CO_CM>
The content of the configuration management menu mainly depends on the operation mode of the
device. There are four possible modes of the device operation:
CO – All channels are in the Master mode, manual configuration.
CP – All channels are in the Slave mode, manual configuration.
CX – Some Channels are in Master, some channels are in Slave mode, manual configuration.
CA - Configuration of E1 and WAN streams is received from the SHDSL line, automatic config.
In the CA mode, it is impossible to configure the channel reservation, to arbitrarily assign E1
streams to DSL channels and to arbitrarily set clock sources. Nevertheless, this mode satisfies 90%
of users, because it does not require many efforts to configure the device.

WARNING
FOR LOW BASERATES YOU SHOULD USE THE LOWEST POSSIBLE
NUMBER OF CODE LEVELS. FOR A STANARD BASED DEVICE USE
PAM16 AND NOT PAM32.
On the Slave device, the <BASERATE AUTO> command adapts the rate of the Slave device to the
rate of the Master device. In this case, PAM and Annex are automatically detected (opposite Annex
in the <CONFIG> configuration AB appears, opposite PAM is Auto). The command does not change
the Annex and PAM modes in the configuration. In the Slave mode, the <BASERATE AUTO>
command automatically detects all configurations.
4.6.5.7 <PAM [16/32] [N]> or <PAM [4-128] [N]> Command
This command sets the number of levels in the line code. The following options are possible –
4,8,16, 32, 64 & 128 for EXT mode ON. For modems with just one SHDSL channel, the command is
entered without typing the number N
CO_CM>PAM 16
4.6.5.8 <PAYLOAD list/NONE [N=1..4]> Command
This command sets the list of streams transmitted over the SHDSL channel. N is the number of the
SHDSL channel. The parameter list displays the list of E1, V.35 (Nx64) and WAN interfaces
(Ethernet), separated by comma. The E1 interface may be denoted both by a short-form (for
example E1-1, E11), and by numbers (for example 1). Spaces in the list are not allowed. The
parameter NONE deactivates transmission of E1 and WAN over this SHDSL interface. For modems
with just one SHDSL channel, the command is entered without typing the number N
CO_CM>PAYLOAD V35,WAN
CO_CM>PAYLOAD E11,WAN
CO_CM>PAYLOAD NONE
4.6.5.9 <ANNEX A/B/AB [N=1..4]> Command
This command enables the transmission standard G.991.2 ANNEX A or ANNEX B, where N is the
number of the SHDSL interface. The ANNEX AB automatically selects the transmission standard.
Note:
If devices use different transmission standards, synchronization will not be established
between them.
4.6.5.10 <SETCLOCK list [N=1..4]> Command
This command sets the priority list of clock sources for the SHDSL channel, where N is the number
of the SHDSL channel. The parameter N can be absent for single-channel modems. The possible
clock sources are:
External sync source: EXT, EXTERNAL
first E1 channel: 1, E11, E1-1, E1_1
second E1 channel: 2, E12, E1-2, E1_2
third and fourth E1 channel
Nx64 interface: V35
internal sync source: INT, INTERNAL
The external clock source should be either the first one in the priority list or be not used at all. The
next clock sources in the list should be E1 channels and/or Nx64 interface. The internal clock source
should be the last one in the priority list. It is even not necessary to type it in the command.
Page 70
DT Etherlink IV User Manual
- 70 -
Two rules: The list of priority clock sources should contain only those E1 channels, which are used
to transmit data over the SHDSL channel. If the SHDSL channel does not transmit any E1 streams,
it is possible to set any of the E1 channel as a reference clock source or to use the external clock.
Note:
If the list of the E1 channels transmitted over DSL is changed by the PAYLOAD
command, it can change the list so that it corresponds to the previous two criteria.

4.6.5.11 <MULTIPAIR [2/3/4/2+2/OFF]> Command
This command activates the multipair mode, which allows to merge DSL channels.
Groups of 2, 3 and 4 channels can be merged into the multipair mode. The following variants are
possible:
CO_CM>MULTIPAIR 2
CO_CM>MULTIPAIR 3
CO_CM>MULTIPAIR 4
CO_CM>MULTIPAIR 2+2
4.6.5.12 <RESERVE [list]>, <RESERVE [list] [list]> Command
This command allows combining SHDSL channels into groups in order to reserve them. Not more
than 2 groups are possible in a system with 4 SHDSL channels. The reservation groups are called A
and B groups. The parameter sets the list of channel numbers separated by a comma. To simplify
configuration and maintenance of devices, any groups of successive channels can be reserved. To
configure the reserve group, type the following command:
CO_CM>RESERVE 1,2
To configure two reserve groups type the command as follows. Note that groups should not use
same channels.
CO_CM>RESERVE 1,2 3,4
The parameter NONE deactivates reservation.
CO_CM>RESERVE NONE
4.6.5.13 <G704 ON/OFF [N]> Command
This command activates/deactivates the ITU-T G.704 framed mode for the Е1 interface with number
N. The <G704 ON 1> activates the ITU-T G.704 framed mode. The <G704 OFF 1> deactivates the
ITU-T G.704 framed mode, i.e., the devices starts operating in the so-called transparent mode.
CO_CM>G704 ON 1
4.6.5.14 <CRC4 ON/OFF [N]> Command

4.6.5.44 <RSTP [A..E] PRIO [value]> Command
This command allows to setup custom bridge priority for RSTP instance working at specific
PBVLAN. This value represents priority and settable part of bridge id (802.1D - 2004, 9.2.5). Smaller
value denotes better priority. This option allows Root bridge selection for network and it's
replacements in case of faults. Available interval is from 0 to 65535 inclusively. It is recommended to
use values from 0 to 61440 while each value should be multiple of 4096.
Default RSTP bridge priority is 32768.

RSTP BPDU packets in egress direction and will work in Designated state. Other packets will be
forwarded. But if it will receive BPDU in ingress direction, it will switch its role to EDGE OFF and will
fall into Forwarding or Blocked state depends on network topology. If EDGE is manually set to OFF,
it will never become EDGE port, i.e. if BPDU packet will not be received after 30 seconds the port
will fall into Blocked state. Available interfaces are:

PBVLANs are used as a way to isolate groups of network interfaces from each other. No frames
from interface LAN2 connected to PBVLAN A will ever be forwarded to interface INT, which is
connected to PBVLAN E. And vice versa.
Each PBVLAN is a separate switching fabric. As there are 5 PBVLAN and no more than 10 network
interfaces in the modem, one can connect any WAN interface to any LAN interface exclusively, as
well as create isolated LAN-LAN or LAN-INT connections. Each PBVLAN can include from none to
all interfaces. To populate PBVLAN with interfaces, just set the appropriate PBVLAN letter for
selected interfaces.
PBVLAN isolation works only in the limits of one modem. Outside the modem, there is no
information about the PBVLAN letter the frame had inside. This is the major difference with VLANs,
where the VLAN information is carried in the VLAN tag. So, it does not hurt if WAN1, PBLAN A on
one modem is connected to WAN1, PBVLAN C on another.
PBVLAN isolation also affects aggregation of WANs in MWAN (multi-WAN). Only WAN channels
from the same PBVLAN will aggregate with each other. For example, if WAN1 and WAN3 are in
PBVLAN A, and WAN2 and WAN4 are in PBVLAN B, and all WANs go in one direction, two
MWANs will be created each consisting of 2 WANs instead of 1 MWAN with 4 WANs.
Creating a PBVLAN with only LAN ports and one WAN port will allow the modem to eliminate most
software processing of frames, creating bridge connection and thus reducing frame propagation
delay. The same applies to the case when there are several WAN ports in the PBVLAN, but they all
go in the same direction. Assigning INT port to the PBVLAN with LAN and WAN will turn on the
internal Layer2 switch. This will, however, not be sensible in most of the applications.
Most setups where LAN traffic separation is needed can be made with PBVLANs only or VLANs
only. In some setups PBVLANs way has benefits, in some the VLAN way. Mix of VLANs and
PBVLANs is also convenient in some applications. The user can select the approach.
4.6.5.53 <MODE [IF] [ACC/TRUNK/MIX]> Command
This command selects the 802.1Q VLAN mode for any LAN interface. Along with the full words
ACCESS, TRUNK and MIXED, also abbreviations can be used, for example A or ACC for ACCESS,
MIX or M for MIXED.
In ACCESS mode only untagged frames pass into (ingress) and out of (egress) the LANx port. On
ingress, frames are assigned to default VLAN tag with VID and QoS defined by QOS, VLAN and
VID commands. On egress, only frames with VLAN equal to the default VLAN of the port (set with
VLAN command) are allowed, and the VLAN tag is removed.
In TRUNK mode only tagged frames pass into and out of the LANx port. Frames are allowed to pass
on per-VLAN basis. VLANs allowed to pass are those selected with the ALLOW command (any
combination of VLAN1-8 and OTHER can be selected).
In MIXED mode tagged and untagged traffic is allowed on the port. However, on ingress, a default
VLAN tag (selected with QOS, VLAN and VID commands) is added to untagged frames so that all
frames in the system are actually tagged. On egress frames with VLAN equal to the default VLAN
(set with VLAN command) exit the port untagged, while to all other VLANs apply pass/block rules
are set by the ALLOW command.

4.6.5.54 <VLAN [IF] [1..8]> Command
This command sets default VLAN number for interfaces in ACCESS or MIXED mode ([IF] is LANx,
INT). Default VLAN is used to assign VLAN information for untagged traffic.
In ACCESS mode, only frames with VLAN equal to port's default VLAN are allowed to egress.
In MIXED mode, frames with VLAN equal to port's default VLAN egress untagged. Frames of al
other VLANs are blocked or are allowed to egress tagged according to rules set by ALLOW
command.
In both ACCESS and MIXED modes ingressing untagged frames are assigned to default VLAN.
There are 8 separately managed VLANs in the modem. For each managed VLAN the VID (VLAN
ID) can be selected with the VID command.
4.6.5.55 <QOS [IF] [0..7]> Command
This command sets default QoS for interfaces in ACCESS or MIXED mode ([IF] is LANx, INT). The
Lowest priority is 0, the highest is 7. Default QoS is used to assign quality of service information for
ingressing untagged traffic.
The INT interface is always considered in ACCESS mode and all frames coming from the INT
interface will have default QoS assigned.
4.6.5.56 <ALLOW [IF] [VLAN list]> Command
This command selects which VLANs are allowed on interfaces in TRUNK or MIXED mode ([IF] is
LANx, WANx).
The VLAN list is a comma-separated list of allowed VLANS from 1 to 8, and the word OTHER
(allows all other VLANs except 1-8). Spaces in the list are not allowed. To allow all VLANS on the
interface, write ALL in the list.
CP_NET>ALLOW LAN1 1,2,3
CP_NET>ALLOW WAN2 5,3,OTHER
CP_NET>ALLOW WAN4 ALL
4.6.5.57 <VID [1-8] ID> Command
The <VID [1...8] ID> command sets VID for the VLAN with the number 1..8 equal to the ID
parameter. ID=1...4094. 8 VLANs are supported by the device, and available VID numbers assigned
to the VLAN are in the range from 1 to 4094. VID as well as QoS are an attribute of the VLAN
packet.
4.6.5.58 <SETIP X.X.X.X> Command
The <SETIP A.B.C.D> command sets the IP-address of the modem. The parameter A, B, C and D
can take values from 0 to 255 (note that neither address of the network nor the address of the node
can be equal to 0, or to 255).
4.6.5.59 <NETMASK X.X.X.X> Command
The <NETMASK A.B.C.D> command sets the subnet mask of the modem.
4.6.5.60 <GATEWAY X.X.X.X> Command
The <GATEWAY X.X.X.X> sets the default IP address of the router.

4.6.5.61 <MTU> Command
This command sets the MTU size (Maximum Transmission Unit) for the port INT and is used just for
management. Standard is 1500. For all other interfaces MTU is 2048.
4.6.5.62 <WANIDLE [1/7E]> Command
This command sets the idle pattern for a WAN interface. Sometimes, when the unit transmits
Ethernet over E1, then an idle pattern of 1 is not convenient because the some E1 equipment will
detect a Loss of Signal. In this case, the change of the idle pattern to 7E can help.
4.6.5.63 <ETHSD [10H/10F/100H/100F/AUTO] [N=1..5]> Command
The <ETHSD [10H/10F/100H/100F/AUTO] [N=1..5]> command sets the operating mode of the
Ethernet port, where N is the number of the Ethernet port, 10/100 is the rate of 10 or 100 Mbit/s, F is
full duplex and H is half duplex.
The <ETHSD AUTO> command activates the rate and duplex auto detection.
CO_CM>ETHSD 10H 1
CO_CM>ETHSD AUTO 2
4.6.5.64 <FC [ON/OFF] [N1-4]> Command
This command enables and disables IEEE 802.3x flow control on LAN ports.
4.6.5.65 <IRATE [speed/OFF] [N1-4]> Command
The command IRATE is an abridgement of the Ingress Rate. It limits the incoming data stream that
reaches the internal Hardware Ethernet Switch. The IRATE can be set up for every LAN port
separately.
IRATE command counts all arriving traffic without discrimination between ingress VLAN numbers
and QoS settings. It means that IRATE command should be used when the LAN port is set to
ACCESS mode, so all traffic will be processed by the internal switch with selectable VLAN and QoS
settings. If incoming traffic has bigger bandwidth then selected by IRATE command, the excess will
be dropped if Flow Control is disabled on the port, or the switch will send so called “MAC Pause
Frame” if the Flow Control is enabled.
In general it is possible to use IRATE command if LAN port is set to TRUNK or to MIXED mode.
IRATE command will limit the whole incoming bandwidth without taking into account VLAN tags and
priorities inside incoming traffic. In that case a network will work without QoS support but with
bandwidth control.
IRATE [rate] [N]: Sets the desired rate limit.
IRATE OFF [N]: Disable rate limiting.
The parameter [rate] is expressed in kbits or Mbits, for example:
128 means 128 kbps
256k means 256 kbps
1M means 1000kbps
Page 83
DT Etherlink IV User Manual
- 83 -
4.6.5.66 <ERATE [speed/OFF]> Command
The command ERATE is an abridgement of Egress Rate. It limits the traffic heading to CPU of the
device.
ERATE command counts all traffic, but unlike IRATE command the QoS settings make sense for
traffic drop. In case if traffic has bigger bandwidth then the ERATE settings the device will drop
traffic starting from packets with low priority tag.
Network administrator can configure QoS with IRATE and ERATE commands if LAN ports of the
device works in ACCESS mode. He has to be sure that those LAN ports of the device have different
default QoS or VLAN settings.
ERATE [rate]: Sets the desired rate limit.
ERATE OFF: Disable rate limiting.
The parameter [rate] is expressed in kbits or Mbits, for example:
30M means 30000kbps
4.6.5.67 <CRATE [speed] [CoS] [WAN]> Command
The command CRATE is an abridgement of CoS Rate. It limits the egress bandwidth of selected
CoS queue for specified WAN interface. Starting from the 1.3.0 firmware S-Access ETH_IV and
AccessMini devices have 4 CoS queues with numbers from 0 to 3. The queue with “0” number has
the lowest priority while the queue with “3” number has highest priority. Command CRATE is not
intended to define QoS [0…7] to CoS; or VLAN ID to CoS mapping. On the contrary, it is designed
for assigning bandwidth each CoS queue can occupy.
Only CRATE command can be used if incoming traffic has VLANs, IRATE command is useless
because the hardware Ethernet switch can’t check the QoS filed on its entry point. CRATE can be
used too if the traffic is not intended for LAN interface, for example repeater applications or interface
converter mode when traffic is transmitted between two or several WAN interfaces.
Page 84
DT Etherlink IV User Manual
- 84 -
If the sum of all CRATE settings and their load is bigger than the working bandwidth of WAN or
MWAN interfaces, queues with high priority will be served firstly, while other queues will be hold in
buffer and will wait for an opportunity to be transmitted.
CRATE [rate] [CoS:0..3] [WAN:1..4]: Sets the desired rate limit.
CRATE OFF [CoS:0..3] [WAN:1..4]: Disable rate limiting.
Examples: CRATE 128 2 1 – Sets rate limit to 128kbps for CoS2 on WAN1.
4.6.5.68 <COS [QOS/VLAN] [N] [0..3/OFF]> Command
This command sets the VLAN to CoS and QoS to CoS mapping.
COS [VLAN/QOS] [V=1..8/Q=0..7] [CoS=0..3/OFF]
VLAN: Change VLAN-to-CoS mapping
QOS: Change QoS-to-CoS mapping
V: VLAN number (1..8) according to NETCONFIG table
Q: IEEE 802.1p QoS (0..7)
CoS: Resulting CoS (0..3)
OFF: Turns off VLAN-to-CoS mapping for selected VLAN.
Examples: COS VLAN 1 3 - All frames in VLAN 1 will have CoS 3.
4.6.5.69 <TRAPIP [ADD/DEL] X.X.X.X> Command
This command lets you specify IP addresses to send SNMP traps to.
The <TRAPIP ADD X.X.X.X> command adds the IP-address X.X.X.X to the SNMP-trap list.
The <TRAPIP DEL X.X.X.X> command deletes the IP-address X.X.X.X from the SNMP trap list.
The list should not contain more than two IP addresses.
4.6.5.70 <COMMUNITY> Command
With this command you can specify the SNMP community name to authenticate incoming and
outgoing SNMP traps. After entering the command, you will be asked to enter the community name.
Please note, that the SNMP community name is case sensitive.
4.6.5.71 <SNMPSET [ON/OFF]> Command
The <SNMPSET ON> command enables processing SNMP SET requests, which allow to configure
and manage the device, however, this command makes the device sensitive to attacks over SNMP
in unprotected PC networks.
The <SNMPSET OFF> command disables processing SNMP SET requests, what protects the
device from network attacks, but does not allow to configure and manage it.
Use this command to process SNMP SET requests only in protected networks. If the network is not
protected, use this command during configuration and administration only.
4.6.5.72 <NETDEFAULT> Command
The <NETDEFAULT> command sets the following configuration The MAC address of the modems
takes the manufacturer value. The default IP address, sub-network masks and gateway are not
changed.

correspond to specified technical conditions.
5) Transportation except when the shipping is performed by an authorized dealer or a
service center.
7) Defects of the system into which this product is included.
If the equipment should be powered from a primary DC source (38 … 72 V), please us it with
the grounded “+”.
Environment requirements: Temperature: from -5 to +45 °C; Relative air humidity: from 5% to
85% at +25 °C. Exceptions are units that are specified from the manufacturer to differ from
these requirements, because there is a special application.
It is strictly prohibited:
a) to alter, delete, remove or make illegible the serial number of the device.
b) to adapt, adjust and change the equipment in order to improve it or extend its applications
without the prior written consent of the manufacturer.
c) to alter or to adjust the equipment without the consent of the manufacturer.
6.2 Evaluation of the Digital Channel Quality and Operation Parameters
The digital channel quality is evaluated by:
The ITU-T Rec. G.826 error performance (G826) monitoring of a SHDSL link is performed
according to ITU-T Rec. G.704, based on CRC (Cyclic Redundancy Check) error detection.
Six CRC6 check bits are generated per SHDSL frame. CRC6 errors are used by the software
to count the block errors of the SHDSL channel.
The Noise Margin (NM) performance monitoring.
The Noise Margin (NM) provides qualitative performance information of a specific SHDSL link
according the ITU-T Rec. G.991.2. The <NM> command is used to show the noise margin. The
recommended NM values should be no less than 6 dB. This value provides the necessary reserve of
the signal/noise margin. It is recommended to perform the Noise Margin performance monitoring
during acceptance tests and in case the system operates not stable. The test is also used to locate
any damaged cable segment.
In addition, it is also recommended to monitor regularly the quality of data transmission over E1
interfaces. On the E1 side, four CRC4 check bits are generated per sub-multiframe (SMF) and
Page 95
DT Etherlink IV User Manual
- 95 -
compared with the corresponding bits of the next SMF. If they do not match, the CRC4 error counter
is incremented.
The G826 command is used to display the G.826 statistics.
The correctness of operation and configurations of network interfaces can be checked by using loop
back tests (LOOP1) and G.826 statistics of E1 interfaces. If LOOP1 is activated on this network
interface and the G826 statistics displays errors, a conclusion can be made that the E1 network
interface of the S-Access Etherlink_IV system is configured improperly or there is a malfunction.
