ATM Mode for Two-Wire or Four-Wire SHDSL

This document describes the ATM Mode for Two-Wire or Four-Wire SHDSL feature on the Cisco 1700 series, Cisco 1800 series, Cisco 26xxXM, Cisco 2691, Cisco 2800, Cisco 3700 series, and Cisco 3800 series routers.

The ATM Mode for Two-Wire or Four-Wire SHDSL feature adds 4-wire support in fixed line-rate mode only on a WIC-1SHDSL-V2 or WIC-1SHDSL-V3 interface card. 2-wire mode supports 2-wire line-rate and auto line-rate. This feature builds on the existing features of the Multirate Symmetrical High-Speed Digital Subscriber Line (G.SHDSL) feature supported on the 1-port G.SHDSL WAN interface card (WIC-1SHDSL). The 4-wire feature of G.991.2 doubles the bandwidth in ATM mode and increases usable distance over two pairs of wires.

The WIC-1SHDSL-V2 and WIC-1SHDSL-V3 support ATM on 2-wire and 4-wire line mode. Embedded Operation Channel (EOC) messages support for customer premises equipment (CPE) is provided for 2-wire and 4-wire modes.

Interface and Controller Numbering on the Cisco 1721 Router

If a WIC-1SHDSL-V2 or WIC-1SHDSL-V3 is installed in a Cisco 1721 router, the interfaces and controllers are assigned numbers based on a numbering scheme that is different from the slot numbering scheme on other Cisco routers. This is because the Cisco 1721 router assigns only a slot number without also assigning a port number. Other Cisco routers typically use a slot and port number combination.

If a WIC-1SHDSL-V2 or WIC-1SHDSL-V3 (the DSL controller) is installed in slot 0, the ATM interfaces (ADSL/SHDSL) will be numbered relative to the DSL controller in slot 0. See Table 2 for examples of the slot numbering scheme on the Cisco 1721 router.

With an ATM card in slot 0, the WIC-1SHDSL-V2 or WIC-1SHDSL-V3 in slot 1 will be numbered relative to the number of ports in slot 0.

If both slots are occupied by DSL controllers, the logical interfaces configured on each controller will have the same number as the slot occupied by the DSL controller. All logical interfaces on the WIC-1SHDSL-V2 will have the same number as the DSL controller.
Table 2 Examples of Slot Numbering on the Cisco 1721 Router
Interface Cards and Controllers Installed

Slot Numbering Assignment
A WIC-1SHDSL-V2 or WIC-1SHDSL-V3 is in slot 0, and an ADSL/SHDSL WIC is in slot 1.
For WIC-1SHDSL-V2 or WIC-1SHDSL-V3:
controller dsl 0
interface atm 0
For ADSL/SHDSL:
interface atm 1 
An ATM card is in slot 0, and a WIC-1SHDSL-V2 or WIC-1SHDSL-V3 is in slot 1. The WIC-1SHDSL-V2 or WIC-1SHDSL-V3 will be numbered relative to the ports in slot 0.
For ADSL/SHDSL:
interface atm 0
For WIC-1SHDSL-V2 or WIC-1SHDSL-V3:
controller dsl 1
interface atm 1
Interface Numbering on Cisco 2800 and Cisco 3800 Series Routers

This section describes the interface numbering scheme for Cisco 2800 and Cisco 3800 series routers. If an interface card is installed in a Cisco 2800 series or Cisco 3800 series router, the interfaces must use a triple-number scheme to identify them. This triple-number assignment is different from the standard interface numbering scheme on other Cisco routers.

Table 3 shows the interface numbering for the onboard Fast Ethernet ports and the interface slots on Cisco 2800 and Cisco 3800 series routers.

Step 4

line-term {co | cpe]

Example:

Router(config-controller)# line-term cpe

Configures the DSL controller line termination as follows:

•co—Central office.

•cpe—Customer premises equipment.

Step 5

dsl-mode shdsl symmetric annex mode

Example:

Router(config-controller)# dsl-mode shdsl symmetric annex A

Sets the DSL operating mode parameters. The valid values are:

•A: Supports Annex A of G.991.2 standard for North America. This is the default.

•B: Supports Annex B of G.991.2 standard for Europe.

•A-B: Supports Annex A or B. For CPE mode only. CO mode is not supported. Selected when the line trains.

•B-ANFP: Supports Annex B-ANFP.

Step 6

ignore-error-duration (seconds)

Example:

Router(config-controller)# ignore-error-duration 15

(Optional) Permits the router to ignore errors for a given amount of time while the line is being trained when connected to a controller with a different chipset type.

•seconds—Number of seconds for which errors are ignored. The range is 15 to 30 seconds. If this value is omitted, an error message appears.

Step 7

mode atm

Example:

Router(config-controller)# mode atm

Enables ATM encapsulation and creates a logical ATM interface slot/port.

Note If the no mode atm command is used to leave ATM mode, the router must be rebooted to clear the mode.
Step 8
For CPE:

line-mode [4-wire [enhanced | standard] | 2-wire line-number | auto}
For CO:

line-mode {4-wire [enhanced | standard] | 2-wire line-number}
Example:

Router(config-controller)# line-mode 4-wire enhanced
(Optional) Configures the controller to operate in 2-wire or 4-wire mode. The 2-wire mode is the default if this step is not configured or if the mode is not specified.

•2-wire—Configures the controller to operate in 2-wire mode. This is the default if this step is omitted or if the mode is not specified.

•4-wire—Configures the controller to operate in 4-wire mode.

–enhanced—Configures 4-wire mode to exchange handshake status on both wire pairs. This is the default if the handshake mode is not specified.

–standard—Configures 4-wire mode to exchange handshake status on the master wire pair only.

•line-number—For 2-wire mode only, specifies the pair of wires used. Valid values are line-zero (default) or line-one. Line-zero choose RJ-11 pin 1 and pin 2; line-one chooses RJ-11 pin 3 and pin 4.

•auto—Configures the line mode to be automatically detected for the CPE. This option is not available for configuring the CO.
Step 9

line-rate {rate | auto}

Example:

Router(config-controller)# line-rate 1024

–For 4-wire mode—384, 512, 640, 768, 896, 1024, 1152, 1280, 1408, 1536, 1664, 1792, 1920, 2048, 2176, 2304, 2432, 2560, 2688, 2816, 2944, 3072, 3200, 3328, 3456, 3584, 3712, 3840, 3968, 4096, 4224, 4352, 4480, and 4608.

Note The configured line rate is the data rate available. Third-party equipment may use a line rate that includes an additional SHDSL overhead of 8 kbps for 2-wire mode or 16 kbps for 4-wire mode.

Step 10

exit

Example:

Router(config-controller)# exit

Exits controller configuration mode.

Step 11

interface atm slot/port

Example:

Router(config)# interface atm 1/0

Enters ATM configuration mode for interface ATM 0 in slot 1.

The keywords and arguments are as follows:

•slot—The backplane slot number for the interface being configured.

•port—The backplane port number for the interface being configured.

Note If a slot has two subslots for WIC modules and no ATM interface is present in subslot 0, the WIC will take ATM x/0 as its interface number even if placed in subslot 1 (ATMx/1).

If a two-port WIC is present in subslot 0, the WIC will use ATM x/2 as its interface number. This subslot number is pertinent to all interface commands such as show interface atm and show dsl interface atm.

Step 12

ip address ip-address subnet-mask

Example:

Router(config-if)# ip address 192.168.10.25 255.255.255.0

Assigns an IP address to the DSL ATM interface.

Step 13

atm ilmi-keepalive [seconds]

Example:

Router(config-if)# atm ilmi-keepalive 5

(Optional) Enables Integrated Local Management Interface (ILMI) keepalives.

•seconds—The number of seconds between keepalives.

•If you enable ILMI keepalives without specifying the seconds, the default time interval is 3 seconds.

Step 14

pvc [name] vpi/vci

Example:

Router(config-if)# pvc [name] vpi/vci

Enters atm-virtual-circuit (interface-atm-vc) configuration mode, and configures a new ATM permanent virtual circuit (PVC) by assigning a name (optional) and VPI/VCI numbers.

The default traffic shaping is an unspecified bit rate (UBR); the default encapsulation is AAL5+LLC/SNAP.

•name—(Optional) Name of the PVC or map. The name can be up to 15 characters long.

•vpi/— ATM network virtual path identifier (VPI) for this PVC. The absence of the "/" and a VPI value causes the VPI value to default to 0.

Value ranges:

–Cisco 2600 and Cisco 3600 series routers using Inverse Multiplexing for ATM (IMA): 0 to 15, 64 to 79, 128 to 143, and 192 to 207

The vpi and vci arguments cannot both be set to 0; if one is 0, the other cannot be 0.

•vci—ATM network virtual channel identifier (VCI) for this PVC. This value ranges from 0 to 1 less than the maximum value set for this interface by the atm vc-per-vp command. Typically, lower values from 0 to 31 are reserved for specific traffic (for example, F4 OAM, SVC signaling, ILMI, and so on) and should not be used.

The VCI is a 16-bit field in the header of the ATM cell. The VCI value is unique only on a single link, not throughout the ATM network, because it has local significance only.

The vpi and vci arguments cannot both be set to 0; if one is 0, the other cannot be 0.

Step 15

protocol protocol [protocol-address]

Example:

Router(config-if-vc)# protocol ip 192.168.0.4

(Optional) Enables IP connectivity and creates a point-to-point IP address for the virtual circuit (VC).

•protocol—Choose the ip protocol for this configuration.

•protocol-address—Destination address that is being mapped to a permanent virtual circuit (PVC).

Step 16

vbr-rt peak-rate average-cell-rate burst

Example:

Router(config-if-vc)# vbr-rt peak-rate average-cell-rate burst

(Optional) Configures the PVC for real-time variable bit rate (VBR) traffic shaping.

•peak rate—Peak cell rate (PCR).

•average-cell-rate—Average cell rate (ACR).

•burst—Burst size in cells.

Step 17

encapsulation {aal2 | aal5ciscoppp | aal5mux | aal5nlpid | aal5snap | aal5autoppp}

Example:

Router(config-if-vc)# encapsulation aal2

(Optional) Configures the ATM adaptation layer (AAL) and encapsulation type.

•aal2—AAL2.

•aal5ciscoppp—Cisco PPP over AAL5.

•aal5mux—AAL5+MUX.

•aal5nlpid—AAL5+NLPID.

•aal5snap—AAL5+LLC/SNAP.

•aal5autoppp—PPP autosense over AAL5.

The default is aal5snap.

Step 18

exit

Example:

Router(config-if-vc)# exit

Exits interface-atm-vc configuration mode.

Step 19

exit

Example:

Router(config-if)# exit

Exits ATM interface configuration mode.

Step 20

exit

Example:

Router(config)# exit

Exits global configuration mode.

Step 21

show interface atm slot/port

Example:

Router# show interface atm 1/0

Displays the ATM interface configuration.

The keywords and arguments are as follows:

•slot—The backplane slot number for the interface being configured.

•port—The backplane port number for the interface being configured.

Step 22

exit

Example:

Router# exit

Exits privileged EXEC mode.

Troubleshooting Tasks

The following commands verify hardware on the router:

•show version—Lists the modules installed in the router. If DSL controllers are installed, the output displays the following line:

–1 DSL controller—Indicates one DSL controller is installed in the router

and one of the following lines:

–1 ATM network interface(s)—If the DSL controller is configured for mode ATM

–1 Channelized T1/PRI port(s)—If the DSL controller is configured for mode T1

•show controllers atm—Displays the ATM controller status and statistics. The sample below shows the output in ATM mode. Actual output may vary depending on the router and the configuration.

Command

Description

controller dsl

Configures the controller status and the controller number.

snr margin

To set the signal-to-noise ratio (SNR) on the controller to improve the line stability, use the snr margin command in controller configuration mode. To reset the SNR to default settings, use the no form of this command.

snr margin {current [snr-value | disable] | snext [snr-value | disable]}

no snr margin {current | snext}

Syntax Description

current

Sets the current signal-to-noise ratio on the controller. To disable the current SNR, set current to disable.

snext

Sets the Self Near End Cross Talk (SNEXT) signal-to-noise ratio. To disable the SNEXT, set snext to disable.

snr-value

(Optional) Value, in decibels (dB), for the signal-to-noise ratio on the controller or the SNEXT. Range is from -10 to 10 . The default value is 0.

disable

(Optional) Disables the snr margin command.

Defaults

The default value for both current and snext is 0.

12.3(4)XD

This command was introduced on the Cisco 2600 series, Cisco 3600 series, and Cisco 3700 series routers.

12.3(4)XG

This command was integrated into Cisco IOS Release 12.3(4)XG on the Cisco 1700 series routers.

12.3(7)T

This command was integrated into Cisco IOS Release 12.3(7)T on Cisco 2600 series, Cisco 3631, and Cisco 3700 series routers.

12.3(11)T

This command was integrated into Cisco IOS Release 12.3(11)T on Cisco 2800 series and Cisco 3800 series routers.

12.3(14)T

This command was integrated into Cisco IOS Release 12.3(14)T on Cisco 1800 series routers.

Usage Guidelines

The snr margin current command can create a more stable line by making the line train more than the current noise margin plus signal-to-noise ratio threshold during training time. If any external noise is applied that is less than the set SNR margin, the line will be stable.

The snr margin snext command can create a more stable line by making the line train more than the Self Near End Cross Talk (SNEXT) threshold during training time. If any external noise is applied that is less than the set SNEXT margin, the line will be stable.

Examples

SNR with SNEXT Disabled

The following example configures the signal-to-noise ratio to 5 dB on the DSL controller in slot 3 and port 0 and disables the SNEXT signal-to-ratio.
Router(config)# controller dsl 3/0
Router(config-controller)# snr margin current 5

Glossary

ABR—available bit rate. An ATM service type in which the ATM network makes a "best effort" to meet the transmitter's bandwidth requirements. ABR uses a congestion feedback mechanism that allows the ATM network to notify the transmitters that they should reduce their rate of data transmission until the congestion decreases. Thus, ABR offers a qualitative guarantee that the transmitter's data can get to the intended receivers without unwanted cell loss.

ATM—Asynchronous Transfer Mode. A form of digitized data transmission based on fixed-length cells that can carry data, voice, and video at high speeds.

CBR—constant bit rate. A data transmission that can be represented by a nonvarying, or continuous, stream of bits or cell payloads. Applications such as voice circuits generate CBR traffic patterns. CBR is an ATM service type in which the ATM network guarantees to meet the transmitter's bandwidth and quality-of-service (QoS) requirements.

CO—central office. Local telephone company office to which all local loops in a given area connect and in which circuit switching of subscriber lines occur.

CPE—customer premises equipment. CPE includes devices, such as CSU/DSUs, modems, and ISDN terminal adapters, required to provide an electromagnetic termination for wide-area network circuits before connecting to the router or access server. This equipment was historically provided by the telephone company, but is now typically provided by the customer in North American markets.

Downstream—Refers to the transmission of data from the central office (CO or COE) to the customer premises equipment (CPE).

G.SHDSL—Multirate Symmetrical High-Speed Digital Subscriber Line.

UBR—unspecified bit rate. QoS class defined by the ATM Forum for ATM networks. UBR allows any amount of data up to a specified maximum to be sent across the network, but there are no guarantees in terms of cell loss rate and delay. Compare with ABR (available bit rate), CBR, and VBR.

Upstream—Refers to the transmission of data from the customer premises equipment (CPE) to the central office equipment (CO or COE).

VBR—variable bit rate. QOS class defined by the ATM Forum for ATM networks. VBR is subdivided into a real time (rt) class and non-real time (nrt) class.

VBR-rt—VBR-real-time is used for connections in which there is a fixed timing relationship between samples.

VBR-nrt—VBR-non-real-time is used for connections in which there is no fixed timing relationship between samples, but that still need a guaranteed QoS. Compare with ABR, CBR, and UBR.

The range is 15 to 30 seconds. If this value is omitted, an error message appears.
Step 7	mode atm Example: Router(config-controller)# mode atm	Enables ATM encapsulation and creates a logical ATM interface slot/port. Note If the no mode atm command is used to leave ATM mode, the router must be rebooted to clear the mode.
Step 8	For CPE: line-mode [4-wire [enhanced \| standard] \| 2-wire line-number \| auto} For CO: line-mode {4-wire [enhanced \| standard] \| 2-wire line-number} Example: Router(config-controller)# line-mode 4-wire enhanced	(Optional) Configures the controller to operate in 2-wire or 4-wire mode. The 2-wire mode is the default if this step is not configured or if the mode is not specified. •2-wire—Configures the controller to operate in 2-wire mode. This is the default if this step is omitted or if the mode is not specified. •4-wire—Configures the controller to operate in 4-wire mode. –enhanced—Configures 4-wire mode to exchange handshake status on both wire pairs. This is the default if the handshake mode is not specified. –standard—Configures 4-wire mode to exchange handshake status on the master wire pair only. •line-number—For 2-wire mode only, specifies the pair of wires used. Valid values are line-zero (default) or line-one. Line-zero choose RJ-11 pin 1 and pin 2; line-one chooses RJ-11 pin 3 and pin 4. •auto—Configures the line mode to be automatically detected for the CPE.

Note The configured line rate is the data rate available. Third-party equipment may use a line rate that includes an additional SHDSL overhead of 8 kbps for 2-wire mode or 16 kbps for 4-wire mode.
Step 10	exit Example: Router(config-controller)# exit	Exits controller configuration mode.
Step 11	interface atm slot/port Example: Router(config)# interface atm 1/0	Enters ATM configuration mode for interface ATM 0 in slot 1. The keywords and arguments are as follows: •slot—The backplane slot number for the interface being configured. •port—The backplane port number for the interface being configured. Note If a slot has two subslots for WIC modules and no ATM interface is present in subslot 0, the WIC will take ATM x/0 as its interface number even if placed in subslot 1 (ATMx/1). If a two-port WIC is present in subslot 0, the WIC will use ATM x/2 as its interface number. This subslot number is pertinent to all interface commands such as show interface atm and show dsl interface atm.
Step 12	ip address ip-address subnet-mask Example: Router(config-if)# ip address 192.168.10.25 255.255.255.0	Assigns an IP address to the DSL ATM interface.

The default traffic shaping is an unspecified bit rate (UBR); the default encapsulation is AAL5+LLC/SNAP. •name—(Optional) Name of the PVC or map. The name can be up to 15 characters long. •vpi/— ATM network virtual path identifier (VPI) for this PVC. The absence of the "/" and a VPI value causes the VPI value to default to 0. Value ranges: –Cisco 2600 and Cisco 3600 series routers using Inverse Multiplexing for ATM (IMA): 0 to 15, 64 to 79, 128 to 143, and 192 to 207 The vpi and vci arguments cannot both be set to 0; if one is 0, the other cannot be 0. •vci—ATM network virtual channel identifier (VCI) for this PVC. This value ranges from 0 to 1 less than the maximum value set for this interface by the atm vc-per-vp command. Typically, lower values from 0 to 31 are reserved for specific traffic (for example, F4 OAM, SVC signaling, ILMI, and so on) and should not be used. The VCI is a 16-bit field in the header of the ATM cell. The VCI value is unique only on a single link, not throughout the ATM network, because it has local significance only. The vpi and vci arguments cannot both be set to 0; if one is 0, the other cannot be 0.
Step 15	protocol protocol [protocol-address] Example: Router(config-if-vc)# protocol ip 192.168.0.4	(Optional) Enables IP connectivity and creates a point-to-point IP address for the virtual circuit (VC). •protocol—Choose the ip protocol for this configuration. •protocol-address—Destination address that is being mapped to a permanent virtual circuit (PVC).
Step 16	vbr-rt peak-rate average-cell-rate burst Example: Router(config-if-vc)# vbr-rt peak-rate average-cell-rate burst	(Optional) Configures the PVC for real-time variable bit rate (VBR) traffic shaping. •peak rate—Peak cell rate (PCR). •average-cell-rate—Average cell rate (ACR). •burst—Burst size in cells.
Step 17	encapsulation {aal2 \| aal5ciscoppp \| aal5mux \| aal5nlpid \| aal5snap \| aal5autoppp} Example: Router(config-if-vc)# encapsulation aal2	(Optional) Configures the ATM adaptation layer (AAL) and encapsulation type. •aal2—AAL2. •aal5ciscoppp—Cisco PPP over AAL5. •aal5mux—AAL5+MUX. •aal5nlpid—AAL5+NLPID. •aal5snap—AAL5+LLC/SNAP. •aal5autoppp—PPP autosense over AAL5. The default is aal5snap.
Step 18	exit Example: Router(config-if-vc)# exit	Exits interface-atm-vc configuration mode.
Step 19	exit Example: Router(config-if)# exit	Exits ATM interface configuration mode.
Step 20	exit Example: Router(config)# exit	Exits global configuration mode.
