Application Notes
Provide Different DSL Port Speeds to different subscribers
An ISP may provide different Line speeds for each DSL port. In our IES-1248 have
an easy way to configure the line speed for each port. It can create some profiles
which can set different parameters to meet the different users’ requirement.
In this application, we will set up two profiles. One is for low speed requirement with
upstream/downstream is 2M/512Kbps and the other is for high speed requirement
with upstream/downstream is 25M/1.2Kbps. We suppose there are general subscribers
from port 1 to port 24 with a low speed profile and some enterprise users from port 25
to port 48 with high speed profile.
How to apply the profile to ports
In this application, we need to configure IES1-1248 and ADSL CPE. We use ZyXEL
Prestige 660R-61 CPE here.
1. IES-1248 Settings
1.1 Profiles settings

configuration screen as shown.

Set up Low Speed Profile. Give this profile a name like Profile_LowSpeed and input
the MaxRate for Up Stream and Down Stream. In this case, we set 512Kbps and
2048Kbps for Up Stream and Down Stream.
Set up High Speed Profile. Give this profile a name like Profile_HighSpeed and input
the MaxRate for Up Stream and Down Stream. In this case, we set 1280Kbps and
24992Kbps for Up Stream and Down Stream.

1.2 Profile Assignment
Click Basic Setting, xDSL Port Setup in the navigation panel to display configuration
screen as shown.
Assign Profile_LowSpeed to port 1. Click a number 1in the Port index field to enter
Port setup screen. Select the Profile_LowSpeed profile and press Apply button.
Copy the settings of port 1 to the ports from 2 to 24.After finishing port 1 setting, the
screen will be back to the xDSL port Setting screen. Select port 1 in Copy Port

combobox. Check the Active and Profile&Mode. After press the Paste button. It will
pop up a screen to select the ports. Select the ports you want to copy the configuration
to and press Apply button. The settings of port 1 will be copied to other ports.
For the high speed profile, you can set the Profile_HighSpeed to port 25. You also can
select ADSL2+ mode in Mode combobox. That will fix the mode on ADSL2+ mode.
Copy the settings of port 25 to the ports from 26 to 48. You can follow the same
procedures as port 1.

2. Prestige 660R-61 Settings
We configure Prestige 660R-61 as bridge mode. The default VPI/VCI of
IES-1248 is 0/33. So we need to set up such values. Prestige 660R-61 has a
Telnet server inside. We need to configure it via Telnet.
2.1 Menu1: General Setup
Go to Menu 1. In this menu, we must set “Rout IP = NO” and “Bridge = YES”.
2.2 Menu4: Internet Access Setup
The encapsulation must be RFC 1483 for bridge mode. The Multiplexing should be
the same as IES-1248. The LLC-based is default mode of IES1248. Additionally, we
must check if the VPI/VCI is the same as IES-1248. The default VPI/VCI of IES1248
is 0/33.

2.3 Menu11.1: Remote Node Profile
In menu11.1, we should activate this profile with “Active= Yes”. The Encapsulation
and the Multiplexing are the same as the menu 4. Setting “Edit ATM Options=Yes”
will enter Menu 11.6.
2.4 Menu11.6: Remote Node ATM Layer Options
Check the values above are the same as the IES-1248.

You can click Basic Setting and xDSL Line Data in navigation Panel to display
configuration screen as shown. Select the port connected to the IES-1248. You will
see the link speed and link mode.
How to configure 802.1Q VLAN
AVLAN (Virtual Area Network) allows a physical network to be partitioned into
multiple logical networks. Stations on a logical network belong to one group called
VLAN group. Astation can belong to more than one group. The stations on the same
VLAN group can communicate with each other. With VLAN, a station cannot directly
talk to or hear from stations that are not in the same VLAN groups.
We want to deploy VALN environment in this application. The following figure
shows the VLAN example. Two PCs connect to the port 1 and port 2 of the line card

and belong to different VLAN. One is VLAN 10 and the other is VLAN 20. So they
can’t communication with each other. But both PC 1 and PC 2 can connect to Internet.
How to set up a VLAN environment.
In this application, we need to configure IES1-1248 and ADSL CPE. We use ZyXEL
Prestige 660R-61 CPE here. Because the two ports belong to different VLAN want to
go to the Internet via Uplink port of IES1248, we need to set up an extra VLAN and
let the two ports be members of this VLAN.
1. IES-1248 Settings
1.1 VLAN settings
Click Advanced Application, VLAN in the navigation panel to display configuration
screen as shown. Click Static VLAN to set the VLAN parameters.
Add VLAN10.Assign Port 1, ENET1 and ENET2 to be members of VLAN10 as
shown.

Add VLAN200.Assign Port 1, Port2, ENET1 and ENET2 to be members of
VLAN200 as shown.

1.2 PVID settings
After set up the three VLAN, we can see Vlan10, Vlan20 and Vlan200 as shown. Now,
click VLAN Port Setting to set the PVID.
We assign VLAN 200(PVID) to ENET1, ENET2. Also, we assign VLAN 10 and
VLAN 20 to Port1 and port2, respectively as shown.

1.3 Port Isolation
If we just want to isolate ports of IES-1248 and don’t want to set any VLAN, there is
another easy way to do this. Click Basic setting, Switch Setup in navigation panel
to display configuration screen as shown. Check Port isolation Active check box.
2. Prestige 660R-61 Settings
Please refer to the procedures in previous application.
Triple play Application
The IES-1248 allows you to use different channels(also called Permanent Virtual
Circuits or PVCs) for different services. Define channels on each DSL port for
different services and assign each channel a priority, a VLAN andATM Quality of
Service (QoS). TheATM QoS allows you to regulate the average rate and fluctuations
of data transmission. This helps eliminate congestion to allow transmission of real
time data (such as audio and video).

IES 1248 Support Notes

In this application, we demonstrate how to set up the multiple PVCs environment.
From the figure below, the PC wants to access the two kinds of network services. One
is the Internet service (data service) and the other is Video service. Because we hope
we can see the video smoothly, we need to set the video service higher priority. In
IES-1248, we can set the two services with different VLANs and assign the PVCs
with different VLAN, priority and ATM QoS. That will make the video traffic get the
higher priority than data traffic. We also can expand this application to triple play
environment.
How to set up a Multiple PVCs environment.
Following procedures will introduce the settings of IES-1248, VLAN-aware switch
and ADSL CPE. We use ZyXEL ES-2024 and Prestige 660R-61 as VLAN-aware
switch and ADSL CPE, respectively.
1. IES-1248 Settings
1.1 VLAN setup
We can set up VLAN like procedure described in VLAN application. Add VLAN10.
Assign Port 1, ENET1 to be members of VLAN10 as show. We need to check the
Tx Tagging on ENET1.

Add Defval_CBR VC profile. Set up Encap, Class, PCR and CDVT as shown. Encap
should be LLC the same as IES-1248. Class should be CBR which has higher priority
in ATM QoS.
1.3 Multiple PVCs setup
Click Basic Setting and xDSL Port Setup in navigation panel to display the
configuration screen as shown. Click VC Setup in this screen.

We hope VPI/VCI with 0/33 get the higher priority. We should modify this VPI/VCI
with Defval_CBR profile which we created before. Press Apply button to make it
take effect.
Then we add the VPI/VCI with 0/34. We apply the DEFVAL profile to this channel.
2. Prestige 660R-61 Settings
We need to set two channels. One is 0/33 and the other is 0/34. From former

application, we already knew how to set up CPE with one channel (0/33). We
just demonstrate how to set up second channel.
2.1 Menu11.1: Remote Node Profile
In menu11.1, we should activate this profile with “Active= Yes”. The Encapsulation
and the Multiplexing are the same as the menu 4. Setting “Edit ATM Options=Yes”
will enter Menu 11.6.
2.2 Menu11.6: Remote Node ATM Layer Options
We should set up another VPI/VCI with 0/34 the same as the IES-1248.
3. ES-2024 settings
3.1 VALN
Click Advanced Application and VLAN in navigation panel to display configuration
screen as shown. Click Static VLAN to show VLAN setup screen.
