Chapter 1

Getting to know the IES-1248

This chapter describes the key features and applications of your IES-1248
1.1 Integrated Ethernet Switch Overview
The Integrated Ethernet Switch is an IP-based DSLAM (Internet Protocol Digital Subscriber Line Access Multiplexer) that connects ADSL subscribers to the Internet.
As a high-performance yet compact platform, the IES-124 can conveniently deliver broadband Internet access to telephone company central offices, multi-tenant units (MTUs), hospitals, hotels, schools, university campuses and ISPs. The IES-1248’s low cost and easy management make it a perfect DSL-provider solution.
The IES-1248 provides ADSL service for 48 subscribers over existing telephone wiring, thus avoiding the cost and hassle of installing new wiring. ADSL allows you to extend the reach of broadband services up to 18,000 feet. This makes the IES-1248 perfect for providing high bandwidth broadband service to subscribers who are spread out over a large area. The built in splitter combines voice service and ADSL on the same telephone wiring.
The IES-1248 is easy to manage.
1.2 System Description
Four Telco-50 Connectors
There are four Telco-50 connectors for ADSL and POTS connections.
1000/100 Mbps Ethernet Ports
The IES-1248 has two 1000/100Mbps auto-negotiating, auto-crossover Ethernet ports.
They allow you to:
Connect the IES-1248 to a second level switch
Daisy-chain other switches
Two Slots for Mini GBIC Modules
The mini GBIC (Gigabit Interface Converter) module transceivers allow flexibility in connection options. You can use mini GBIC transceivers for fiber connections to backbone Ethernet switches.
Stacking
Daisy-chain up to three IES-1248s (or other Ethernet devices).
Integrated Splitters
The integrated DSL splitter eliminates the need to use external splitters that separate the voice-band and ADSL signals.
Getting to know the IES-1248 1-1
Page 28
Console Port
Use the console port for local management of the IES-1248.
Fans
The fans cool the IES-1248 sufficiently to allow reliable operation of the IES-1248, even in poorly ventilated rooms or basements.
IP Protocols
IP Host (No routing)
Telnet for configuration and monitoring
SNMP for management
• SNMP MIB II (RFC 1213)
• SNMP v1 RFC 1157
• SNMPv2, SNMPv2c or later version, compliant with RFC 2011 SNMPv2 MIB for IP, RFC 2012
SNMPv2 MIB for TCP, RFC 2013 SNMPv2 MIB for UDP
• Ethernet MIBs RFC 1643
• Bridge MIBs (RFC 1493, 2674)
• SMI RFC 1155
• Multiple Protocols over AAL5 (RFC 1483)
ADSL Compliance
• Multi-Mode ADSL standard
G.dmt (ITU-T G.992.1)
G.lite (ITU-T G.992.2)
G.hs (ITU-T G.994.1)
ANSI T1.413 issue 2
ADSL2: ITU-T G.992.3, G.992.4
ADSL2+: ITU-T G.992.5
• Rate adaptation support
IEEE 802.1p Priority
1
Your IES-1248 uses IEEE 802.1p Priority to assign priority levels to individual PVCs.
Multiple PVC and ATM QoS
1
At the time of writing, the IES-1248 only supports the line rates for ADSL2 and ADSL2+ (not other features); and the IES-
1248’s interoperability when using ADSL2 and ADSL2+ has not yet been tested.
1-2 Getting to know the IES-1248
Page 29
The IES-1248 allows you to use different channels (also called Permanent Virtual Circuits or PVCs) for different services or subscribers. Define channels
2
on each DSL port for different services or levels of service and assign each channel a priority. ATM Quality of Service (QoS) allows you to regulate the average rate and fluctuations of data transmission. This helps eliminate congestion to allow the transmission of real time data (such as audio and video).
IEEE 802.1x Port-based Authentication
The IES-1248 supports the IEEE 802.1x standard for centralized user authentication and accounting management through an optional network authentication (RADIUS) server.
Management
• Remote configuration backup/restore and firmware upgrade
• SNMP manageable
• Text-based management locally via console port and remotely via telnet
• Editable plain text based configuration file
Security
Password protection for system management
VLAN
MAC (Media Access Control) Count Filter
You can limit the number of MAC addresses that may be dynamically learned on a port. You may enable/disable the MAC count filter on individual ports.
Static Multicast Filter
Use the static multicast filter to allow incoming frames based on multicast MAC address(es) that you specify. This feature can be used in conjunction with IGMP snooping to allow multicast MAC address(es) that are not learned by IGMP snooping.
IGMP Snooping
With IGMP snooping, group multicast traffic is only forwarded to ports that are members of that group. IGMP Snooping generates no additional network traffic, allowing you to significantly reduce multicast traffic passing through your IES-1248.
System Monitoring
• System status (link status, rates, statistics counters)
• Temperatures, voltage reports and alarms.
System Error Logging
2
Up to eight channels on each DSL port at the time of writing.
Getting to know the IES-1248 1-3
Page 30
The IES-1248’s system error log will record error logs locally. These logs may be viewed again after a warm restart.
Alarm LED
An ALM (alarm) LED lights when the IES-1248 is overheated, the fans are not working properly, the voltage readings are outside the tolerance levels or an alarm has been detected on the ALARM input pins.
Bandwidth Control
The IES-1248 supports rate limiting in 64Kbps increments allowing you to create different service plans
Quality of Service
The IES-1248 has four priority queues so you can ensure mission-critical data gets delivered on time.
Follows the IEEE 802.1p priority setting standard.
Flow Control
The IES-1248 uses IEEE 802.3 flow control to manage the sending of traffic so the sending device does not transmit more than the receiving device can process. This helps prevent traffic from being dropped and having to be resent.
1.3 Applications
These are the main applications for the IES-1248:
Internet access and multimedia services for Multiple Tenant Units (MTU).
Other applications include telemedicine, surveillance systems, remote servers systems, cellular base
stations and high-quality teleconferencing.
1.3.1 MTU Application
The following diagram depicts a typical application of the IES-1248 with ADSL modems, in a large residential building, or multiple tenant unit (MTU), that leverages existing phone line wiring to provide Internet access to all tenants. ADSL service can coexist with voice service on the same line.

Page 31
Figure 1-1 MTU Application
1.3.2 Curbside Application
The IES-1248 can also be used by an Internet Service Provider (ISP) in a street cabinet to form a “mini POP (Point­of-Presence)” to provide broadband services to residential areas that are too far away from the ISP to avail of DSL services. Residents need an ADSL modem, connected as shown in the previous figure.

The IES-1248 can be placed on a desktop or rack-mounted on a standard EIA rack. Use the rubber feet in a desktop installation and the brackets in a rack-mounted installation.
For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front and 3.4 inches (8 cm) at the back of the switch. This is especially important for enclosed rack installations.
2.3 Desktop Installation Procedure
1. Make sure the switch is clean and dry.
2. Set the switch on a smooth, level surface strong enough to support the weight of the switch and the
connected cables. Make sure there is a power outlet nearby.
3. Make sure there is enough clearance around the switch to allow air circulation and the attachment of cables
and the power cord.
4. Remove the adhesive backing from the rubber feet.
5. Attach the rubber feet to each corner on the bottom of the switch. These rubber feet help protect the switch
from shock or vibration and ensure space between switches when stacking.
Hardware Installation 2-1

Figure 2-1 Attaching Rubber Feet
Do not block the ventilation holes. Leave space between switches when stacking.
2.4 Rack-mounted Installation Requirements
The switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other equipment. Follow the steps below to mount your switch on a standard EIA rack using a rack-mounting kit.
Make sure the rack will safely support the combined weight of all the equipment it contains.
Make sure the position of the IES-1248 does not make the rack unstable or top-heavy. Take all
necessary precautions to anchor the rack securely before installing the unit.
Use a #2 Philips screwdriver to install the screws.
Refer to the appendices for the gauge of wire to use for the frame ground connections.
Refer to the appendices for the hardware that is required to mount the IES-1248.
Failure to use the proper screws may damage the unit.
Do not block the ventilation holes. Leave space between IES-1248s when stacking.
2.5 Rack-Mounted Installation
1. Align one bracket with the holes on one side of the switch and secure it with the bracket screws (smaller
than the rack-mounting screws).
2. Attach the other bracket in a similar fashion.

3.5 1000/100M Auto-Sensing Ethernet
The IES-1248 has two 1000/100Mbps auto-sensing Ethernet ports. There are two factors related to Ethernet: speed and duplex mode. In 1000/100Mbps Fast Ethernet, the speed can be 100Mbps or 1000Mbps and the duplex mode can be half duplex or full duplex. The auto-negotiation capability makes one Ethernet port able to negotiate with a peer automatically to obtain the connection speed and duplex mode that both ends support.
3-2 Front Panel Connections
Page 41
When auto-negotiation is turned on, an Ethernet port on the IES-1248 negotiates with the peer automatically to determine the connection speed and duplex mode. If the peer Ethernet port does not support auto-negotiation or turns off this feature, the IES-1248 determines the connection speed by detecting the signal on the cable and using half duplex mode. When the IES-1248’s auto-negotiation is turned off, an Ethernet port uses the pre-configured speed and duplex mode when making a connection, thus requiring you to make sure that the settings of the peer Ethernet port are the same in order to connect.
Each 1000/100M RJ-45 Ethernet port is paired with a mini GBIC slot. The IES-1248 uses up to one connection for each pair for a total of two possible gigabit connections (one from each of the two pairs).
When the IES-1248 is in standalone mode (default), you can connect both of the Ethernet ports to the Ethernet backbone. You can use it with a ring network configuration (you must also enable RSTP).
When the IES-1248 is in daisychain mode, connect Ethernet port 1 to the Ethernet backbone and connect Ethernet port 2 to another IES-1248 or other Ethernet switch.
3.6 SFP Mini GBIC Slots
The SFP slots can each house a mini GBIC (Gigabit Interface Converter) transceiver. A transceiver is a single unit that houses a transmitter and a receiver. The IES-1248 does not come with a transceiver. You must use a transceiver that complies with the Small Form-factor Pluggable (SFP) Transceiver MultiSource Agreement (MSA). See the SFF committee’s INF-8074i specification Rev 1.0 for details.
You can change transceivers while the IES-1248 is operating. You can use different transceivers to connect to Ethernet switches with different types of fiber-optic connectors.
To avoid possible eye injury, do not look directly into an operating fiber-optic module’s
connectors.

Type: SFP connection interface
Connection speed: 1 Gigabit per second (Gbps)
3.6.1 Transceiver Installation
Use the following steps to install a mini GBIC transceiver (SFP module) in the SFP slot.
The SFP slot is at an angle. Do not attempt to straighten it.
1. Remove the dust cover from the transceiver.
2. For transceivers with a flip-up or flip-down latch, close the latch.

Connect the mini-RJ-11 male end of the console cable to the console port of the IES-1248. Connect the female end to a serial port (COM1, COM2 or other COM port) of your computer.
3.8 ALARM Connections
A closed circuit on the ALARM input pins indicates an alarm. Pins 7 and 3 are alarm input one. Pins 8 and 4 are alarm input two. Pins 9 and 5 are alarm input 3.
The IES-1248 signals an alarm when it detects an alarm on the ALARM input pins or the IES-1248.
To signal an alarm, the IES-1248 opens the circuit for pins 1 and 6 (the common pin) and closes the circuit for pins 2 and 6.
Examples of an alarm on the IES-1248 are when the IES-1248’s voltage or temperature is outside of the normal range.

Connect the lines from the user equipment (ADSL modems) to the USER Telco-50 connector and the lines from the central office switch or PBX (Private Branch Exchange) to the
USER line and the CO lines are not shorted on the MDF (Main Distribution Frame).
The line from the user carries both the ADSL and the voice signals. For each line, the IES-1248 has a built-in splitter that separates the high frequency ADSL signal from the voice band signal and feeds the ADSL signal to the IES-1248, while the voice band signal is diverted to the CO port. See Chapter 4 for more information on the Telco- 50 connections.

MDF Connections

This chapter shows you how to connect the Telco-50 connectors to an MDF.
4.1 MDF Connections Overview
Observe the following before you start:
Refer to the Hardware Specifications Appendix for the gauge of telephone wire to use.
Follow the pin assignments shown in Hardware Specifications Appendix to wire Telco-50 cables to Telco-
50 connectors.
4.2 MDF (Main Distribution Frame)
An MDF is usually installed between subscribers’ equipment and the telephone company (CO) in a basement or telephone room. The MDF is the point of termination for the outside telephone company lines coming into a building and the telephone wiring in the building.
Figure 4-1 MDF (Main Distribution Frame) Wiring
Connect wiring to end-user equipment to the lower ports of an MDF and connect wiring from the telephone
company to the upper ports of an MDF (see the previous figure).
Some MDFs have surge protection circuitry built in between the two banks; thus, do not connect telephone
wires from the telephone company directly to your IES-1248.
Use a punch-down tool to seat telephone lines into MDF blocks.
Multiple upper and lower MDF port connections are shown as one line in the following figures.
MDF Connections 4-1
Page 46
4.3 Telco-50 Cables
Telco-50 cables are used for data and voice applications with MDFs (Main Distribution Frame), patch panels and distribution boxes. They can also be used as extension cables. Telco-50 cables are made up of 25 twisted-pair copper wires.
Connect a Telco-50 connector to one end of the cable (see the Hardware Specifications Appendix for pin assignments) and connect the other end directly to an MDF; alternatively attach RJ-11 connectors and connect directly to DSL modem(s).
Figure 4-2 Telco-50 Cable with RJ-11 Connectors
4.4 Telco-50 Connections
The internal DSL splitters separate the voice signals from the DSL signals. They feed the DSL signals to the IES­1248 and divert the voice signals to the CO Telco-50 connectors.
Connect the CO Telco-50 connectors to the PBX or PSTN/ISDN switch.
Connect the USER Telco-50 connectors to the subscribers’ telephone wiring. In most multi-tenant unit applications, the USER pins connect to the subscribers’ telephone wiring via Main Distribution Frame (MDF).
See the section on MDF scenarios and the pin assignments in the Hardware Specifications Appendix for details on Telco-50 connections.

6. Skip to step 15 if you have your subscribers use VPI 0 and VCI 33 (the default for all of the ADSL ports).
Otherwise, use the following steps to change the VPI and VCI settings for all of the ADSL ports.
First you will delete the default virtual channel from all of the ADSL ports (you cannot edit it). Adding another virtual channel without deleting the default virtual channel is not recommended since you cannot set the new channel to be the port’s super channel. The super channel can forward frames belonging to multiple VLAN groups (that are not assigned to other channels). A channel that is not the super channel can only forward frames with a single VLAN ID (that is configured on that channel). The IES-1248 would drop any frames received from the subscriber that are tagged with another VLAN ID.
Then you will configure a new virtual channel for a port and copy it to the other ADSL ports.

Cancel Click Cancel to start configuring the screen again.
10.4 IGMP Snooping
IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to establish membership in a multicast group - it is not used to carry user data. Refer to RFC 1112 and RFC 2236 for information on IGMP versions 1 and 2 respectively.
A layer-2 switch can passively snoop on IGMP Query, Report and Leave (IGMP version 2) packets transferred between IP multicast routers/switches and IP multicast hosts to learn the IP multicast group membership. It checks IGMP packets passing through it, picks out the group registration information, and configures multicasting accordingly. IGMP snooping allows the IES-1248 to learn multicast groups without you having to manually configure them.
The IES-1248 forwards multicast traffic destined for multicast groups (that it has learned from IGMP snooping or that you have manually configured) to ports that are members of that group. The IES-1248 discards multicast traffic
10-6 Basic Setting Screens
Page 87
destined for multicast groups that it does not know. IGMP snooping generates no additional network traffic, allowing you to significantly reduce multicast traffic passing through your switch.
10.5 Switch Modes
The IES-1248 supports standalone and daisychain switch modes.
10.5.1 Standalone Switch Mode
“Standalone switch mode” relates to the IES-1248’s operational behavior, not a standalone network topology. The standalone switch mode allows either or both of the IES-1248’s Ethernet ports to connect to the backbone Ethernet network. You can also connect one of the IES-1248’s Ethernet ports to the Ethernet network and the other to another IES-1248 (see Figure 10-3 for an example). When the IES-1248 is in standalone mode, you can use it in a network topology that uses loops (you should also enable RSTP). You can have multiple IES-1248s connected on the same network and set both of them to use standalone mode in order to use them with a network topology that uses loops.
When in standalone switch mode, the IES-1248 uses both Ethernet ports (ENET 1 and ENET 2) as uplink ports and only forwards IGMP queries to the ADSL ports.
Standalone switch mode with port isolation enabled blocks communications between subscriber ports on an individual IES-1248. However, one IES-1248’s subscribers can communicate with another IES-1248’s subscribers if the two IES-1248s’ Ethernet ports are connected to each other (see Figure 10-3 for an example). If you have multiple IES-1248s connected on the same network and set to standalone mode, they do not all need to have the same port isolation setting.
10.5.2 Port Isolation with Standalone Switch Mode Example
The following graphic shows IES-1248s 1 and 2 connected to each other and the Ethernet backbone switch (3) in a network topology that creates a loop. The IES-1248s are using the standalone switch mode and have RSTP enabled.
In this example, both IES-1248s have port isolation turned on. Communications between A and B must first go through another switch (3 in the figure). However, A and B can communicate with C without their communications going through another switch or router.
Basic Setting Screens 10-7
Page 88
Figure 10-3 Port Isolation with Standalone Switch Mode Example
10.5.3 Daisychain Switch Mode
Daisychain switch mode sets the IES-1248 to use Ethernet port one (ENET 1) as an uplink port to connect to the Ethernet backbone and Ethernet port two (ENET 2) to connect to another (daisychained or subtending) IES-1248. The daisychain switch mode is recommended for use in a network topology that does not have loops. When you daisychain multiple IES-1248s they must all be set to daisychain mode.
In daisychain switch mode, the IES-1248 forwards IGMP queries from Ethernet port one (ENET 1) to Ethernet port 2 (ENET 2) and to the ADSL ports. Daisychain switch mode is recommended for using IGMP snooping with daisychained (cascaded) IES-1248s.
Daisychain switch mode with port isolation enabled blocks communications between subscriber ports on an individual IES-1248 and between the subscribers of any daisychained IES-1248s (see Figure 10-4 for an example). Use the same port isolation setting on all IES-1248s that you set up in a daisychain.
10.5.4 Port Isolation with Daisychain Switch Mode Example
See the following graphic. IES-1248 1 has its Ethernet port one (ENET 1) connected to the Ethernet backbone switch (3) and it’s Ethernet port two (ENET2) connected to Ethernet port one (ENET 1) of the daisychained IES­1248 2.
With port isolation turned on, communications between A and B must first go through another switch or router (3 in the figure). A and B also cannot communicate with C without their communications going through another switch or router.

Leave All Timer sets the duration of the Leave All Period timer for GVRP in milliseconds. Each port has a single Leave All Period timer. Leave All Timer must be larger than Leave Timer; the default is 1000 milliseconds.
Port Isolation Turn on port isolation to block communications between subscriber ports. When you enable port
isolation you do not need to configure the VLAN to isolate subscribers.
Switch Mode Select Standalone to use both of the IES-1248’s Ethernet ports (ENET 1 and ENET 2) as uplink
ports.
Standalone mode is recommended for network topologies that use loops.
Use Daisychain mode to cascade (daisychain) multiple IES-1248s. The IES-1248 uses Ethernet port one (ENET 1) as an uplink port to connect to the Ethernet backbone and uses Ethernet port two (ENET 2) to connect to another (daisychained or subtending) IES-1248.
Daisychain mode is recommended for network topologies that do not use loops.
Priority Queue Assignment
IEEE 802.1p defines up to 8 separate traffic types by inserting a tag into a MAC-layer frame that contains bits to define class of service. Frames without an explicit priority tag are given the default priority of the ingress port. Use the next two fields to configure the priority level-to-physical queue mapping.
The switch has 4 physical queues that you can map to the 8 priority levels. On the switch, traffic assigned to higher index queues gets through faster while traffic in lower index queues is dropped if the network is congested.
See also Queuing Method and Priority in Port Setup for related information.
Priority Level (The following descriptions are based on the traffic types defined in the IEEE 802.1d standard (which incorporates IEEE 802.1p).

Speed Mode Select the type of Ethernet connection for this port. When you don’t use auto-negotiation, you must
make sure that the settings of the peer Ethernet port are the same in order to connect.
Select Auto (auto-negotiation) to have the IES-1248 automatically determine the type of connection that the Ethernet port has. When the peer Ethernet device has auto-negotiation turned on, the IES­1248 negotiates with the peer to determine the connection speed. If the peer Ethernet port does not have auto-negotiation turned on, the IES-1248 determines the connection speed by detecting the signal on the cable and using full duplex.
When an Ethernet port is set to Auto, the IES-1248 tries to make a fiber connection first and does not attempt to use the RJ-45 port if the fiber connection is successful.
Select 100 Copper if the Ethernet port has a 100 MB electrical connection.

ADSL Port Setup

This chapter explains how to configure settings for profiles and individual ADSL ports. It also covers how
to configure virtual channels and virtual channel profiles.
11.1 ADSL Standards Overview
Table 11-1 Maximum Transfer Rates of the ADSL Ports
STANDARD MAXIMUM DOWNSTREAM MAXIMUM UPSTREAM
G.dmt (IES-1248-71) 8160 Kbps 1024 Kbps
G.dmt Annex B (IES-1248-73) 8160 Kbps 1024 Kbps
ETSI (IES-1248-73) 8160 Kbps 1024 Kbps
ANSI T1.413 issue 2 (IES-1248-71) 8160 Kbps 1024 Kbps
ADSL22 12000 Kbps 1200 Kbps
ADSL2+3 25000 Kbps 1200 Kbps
11.2 Downstream and Upstream
Downstream refers to traffic going out from the IES-1248 to the subscriber’s ADSL modem or router. Upstream refers to traffic coming into the IES-1248 from the subscriber’s ADSL modem or router.
11.3 Profiles
A profile is a table that contains a list of pre-configured ADSL settings. Each ADSL port has one (and only one) profile assigned to it at any given time. The profile defines the latency mode and upstream/downstream latency delay, maximum and minimum upstream/downstream rates, the target upstream/downstream signal noise margins, and the maximum and minimum upstream/downstream acceptable noise margins of all the ADSL ports that have this profile. You can configure multiple profiles, including profiles for troubleshooting.
Profiles allow you to configure ADSL ports efficiently. You can configure all of the ADSL ports with the same profile, thus removing the need to configure the ADSL ports one-by-one. You can also change an individual ADSL port by assigning it a different profile.
For example, you could set up different profiles for different kinds of accounts (for example, economy, standard and premium). Assign the appropriate profile to an ADSL port and it takes care of a large part of the port’s configuration maximum and minimum transfer rates. You still get to individually enable or disable each port, as well as configure its channels and operational mode. See later in this chapter for how to configure profiles.

These are the rates that the IES-1248 supports for the standards at the time of writing.

11.4 Interleave Delay
Interleave delay is the wait (in milliseconds) that determines the size of a single block of data to be interleaved (assembled) and then transmitted. Interleave delay is used when transmission error correction (Reed- Solomon) is necessary due to a less than ideal telephone line. The bigger the delay, the bigger the data block size, allowing better error correction to be performed.
Reed-Solomon codes are block-based error correcting codes with a wide range of applications. The Reed-Solomon encoder takes a block of digital data and adds extra "redundant" bits. The Reed-Solomon decoder processes each block and attempts to correct errors and recover the original data.
11.4.1 Fast Mode
Fast mode means no interleaving takes place and transmission is faster (a “fast channel”). This would be suitable if you have a good line where little error correction is necessary.
11.5 Configured Versus Actual Rate
You configure the maximum rate of an individual ADSL port by modifying its profile (see the Edit Profile screen) or assigning the port to a different profile (see the Edit Port Setup screen). However, due to noise and other factors on the line, the actual rate may not reach the maximum that you specify.
Even though you can specify arbitrary numbers using the Edit Profile screen, the actual rate is always a multiple of 32 Kbps. If you enter a rate that is not a multiple of 32 Kbps, the actual rate will be the next lower multiple of 32Kbps. For instance, if you specify 60 Kbps for a port, the actual rate for that port will not exceed 32 Kbps, and if you specify 66 Kbps, the actual rate will not be over 64Kbps.
Regardless of a profile’s configured upstream and downstream rates, the IES-1248 automatically limits the actual rates for each individual port to the maximum speeds supported by the port’s ADSL operational mode. For example, if you configure a profile with a maximum downstream rate of 25000 Kbps, and apply it to a port set to use G.dmt, the IES-1248 automatically uses a maximum downstream rate of 8160 Kbps. This means that if you configure a profile with very high rates, you can still use it with any port. See Table 11-1 for a list of the maximum rates supported by the different ADSL standards.
11.6 Default Settings
The default profile always exists and all of the ADSL ports use the default profile settings when the IES-1248 is shipped. The default profile's name is set to obtained when using the G.dmt standard. Configure a profile with a maximum downstream rate of 1536 Kbps or less for use with G.lite.

11.9 Virtual Channels
Defining virtual channels (also called Permanent Virtual Circuits or PVCs) allows you to set priorities for different services or subscribers. You can define up to eight channels on each DSL port and use them for different services or levels of service. You set the PVID that is assigned to untagged frames received on each channel. You also set an IEEE 802.1p priority for each of the PVIDs. In this way you can assign different priorities to different channels (and consequently the services that get carried on them or the subscribers that use them).
For example, you want to give high priority to voice service on one of the ADSL ports.
Use the Edit Static VLAN screen to configure a static VLAN on the IES-1248 for voice on the port.
