14 ADSL LIM Hardware ADSL Protocol support ADSL Protocol support Introduction Legacy Stinger ADSL LIMs, designed before the standardization and implementation of ADSL2+ standards, do not have the capability to support ADSL2+. LIMs that have been designed since that time, support ADSL2+ features, depending on the version of TAOS software that is installed. Legacy ADSL protocols All Stinger asymmetric digital subscriber line (ADSL) Annex-A line interface modules (LIMs) provide high-speed asymmetric data interfaces that support data transfer using the ANSI discrete multitone (DMT) and the following protocols: ANSI T1.413 ITU-T G Annex A (ADSL) ITU-T G (ADSL-lite) ADSL2 and ADSL2+ Annex A protocols In addition to the legacy protocols, Annex A LIMs with ADSL2+ capability also support the ADSL protocols and related standards shown below. ADSL protocols and related standards Initial support G Annex A (ADSL2) TAOS G Annex A (ADSL2-lite) TAOS G Annex A (ADSL2+) TAOS TAOS is required for ADSL2+ support on the Stinger Compact Remote. G Annex L (READSL2) TAOS Single-ended loop testing (SELT) TAOS Dual-ended loop testing (DELT) TAOS G Annex M (extended upstream) TAOS G Annex M (extended upstream) TAOS Important! When testing higher data transfer rates on ADSL2+ lines, network equipment, test gear, and all links on the end-user or network must be able to support 10/100Mbps rates. ADSL2+ rates can not be properly tested on a network that does not support 10/100Mbps Ethernet R9.9.1

15 ADSL LIM Hardware ADSL LIM types ADSL LIM types Introduction Four types of Stinger ADSL LIMs, in two broad categories, have been produced as ADSL standards and hardware capabilities have changed. LIM faceplates have changed and some LIMs have added integrated line protection. Legacy ADSL LIMs Legacy ADSL LIMs were the first family of ADSL LIMs produced. They support the legacy ADSL Annex A standards listed previously, and a maximum line rate of 18,016Kbps, but do not support ADSL2+ protocols. LIMs with ADSL2+ capability Integrated line protection LIM faceplates There are three groups of LIMs with ADSL2+ capability. Standard ADSL Annex A LIMs with ADSL2+ capability These cards support all of the protocols listed previously. Enhanced processor LIMs with ADSL2+ capability These cards support all of the protocols listed previously, but use newer processor and components that allow additional IP features and the addition of integrated line protection on one model. High bandwidth LIMs with ADSL2+ capability These LIMs also contain enhanced processor components and support all of the protocols listed previously. When installed in a unit with an IP2100 IP control module these LIMs support a maximum line rate of 24,544Kbps and a total aggregate bandwidth per-card of 550Mbps. When used with other control modules, these LIMs support the lower bandwidth of other ADSL2+ LIMs. The use of enhanced processor components allow for the production of LIMs with integrated line protection hardware. The resulting LIM/LPM card does not require a separate, associated line protection module (LPM). Legacy ADSL Annex A LIMs, and early LIMs with ADSL2+ capability have faceplates with LEDs to indicate the status of individual ports. These LEDs are not present on LIMs that use enhanced processor components. LIMs with integrated line protection hardware have connectors for the line facilities located on the LIM faceplate. These faceplates are illustrated in Figure R

17 ADSL LIM Hardware ADSL LIM products and capabilities ADSL LIM products and capabilities Introduction You cannot fully utilize the capabilities of an ADSL or ADSL2+ LIM unless it is installed in the correct chassis with the proper version of the TAOS software. Stinger FS chassis port limit ADSL LIM product listing The backplane in the original Stinger FS chassis only supports the first 48 ports of any LIMs installed in that chassis. Although 72-port LIMs can be installed in this chassis, only the first 48 ports on the LIM can be utilized. All Stinger FS+, Stinger LS, Stinger RT, and Stinger MS chassis provide full support for 72-port LIMs. LIM Product Codes Initial TAOS Support ADSL support STGR-LIM-AD Legacy ADSL only STGR-LIM-AD Legacy ADSL only Ports per card Compatible Stinger Chassis 48 Stinger FS/FS+, Stinger LS, and Stinger MS+ chassis 72 Stinger FS/FS+, Stinger LS, and Stinger MS+ chassis STGR-LIM-AP ADSL2+ 48 Stinger FS/FS+, Stinger LS, and Stinger MS+ chassis STGR-LIM-AP ADSL2+ 72 Stinger FS/FS+, Stinger LS, and Stinger MS+ chassis STGR-LIM-A2P-72 (Enhanced processor) STGR-LIPM-A2P-72 (Enhanced processor) STGRRT-LIM-AD Legacy ADSL only 9.7 ADSL2+ 72 Stinger FS/FS+, Stinger LS, Stinger MS+, and Stinger RT chassis 9.7 ADSL2+ 72 Stinger FS/FS+, Stinger LS/LS+, and Stinger MS+ chassis 72 Stinger RT chassis STGRRT-LIM-AP ADSL2+ 72 Stinger RT chassis STGRRT-LIM-AP ADSL2+ 48 Stinger RT chassis R

23 ADSL LIM Hardware Interpreting LIM status lights Interpreting LIM status lights Introduction Legacy ADSL LIMs have module and port status lights on the faceplate and do not have any connectors. Connectors for physical line connections are on an associated line protection module (LPM). Enhanced processor LIMs, enhanced processor LIMs with integrated line protection, and high bandwidth LIMs only have module status lights on their faceplate. LIMs with integrated line protection also have connectors for physical line connections. Important! These status lights illuminate briefly upon startup or restart, then remain dark until the module passes its power-on self test (POST). When the module passes the POST and becomes operational, the ACTIVE light illuminates R

33 Interface profile and power parameters ADSL-DMT interfaces ADSL-DMT interfaces Overview The TAOS software creates an al-dmt profile for each ADSL-DMT interface in a Stinger unit. One profile is created for each interface supported by the LIM in a specific slot. Interface identification Example partial listing An al-dmt profile is identified by the chassis (shelf), slot location of the LIM, and port number that is associated with it. ADSL-DMT profiles for interfaces physically located on a local chassis are identified as being on shelf-1. The TAOS interface identifies an interface with the following syntax: { shelf-# slot-# (port) } The following example is a partial list of the profiles created for the interfaces of an ADSL or ADSL2+ LIM installed in slot 2, of a stand-alone Stinger unit. admin> dir al-dmt 44 11/09/ :00:13 { shelf-1 slot-2 1 } 1:2: /20/ :47:43 { shelf-1 slot-2 2 } 1:2: /20/ :47:53 { shelf-1 slot-2 3 } 1:2: /22/ :48:42 { shelf-1 slot-2 4 } 1:2: /22/ :19:28 { shelf-1 slot-2 5 } 1:2: /14/ :32:29 { shelf-1 slot-2 6 } 1:2: /14/ :32:29 { shelf-1 slot-2 7 } 1:2: /22/ :19:57 { shelf-1 slot-2 8 } 1:2: /02/ :20:51 { shelf-1 slot-2 9 } 1:2: /14/ :32:29 { shelf-1 slot-2 10 } 1:2: /14/ :32:29 { shelf-1 slot-2 11 } 1:2: /14/ :32:29 { shelf-1 slot-2 12 } 1:2: /14/ :32:29 { shelf-1 slot-2 13 } 1:2: /14/ :32:29 { shelf-1 slot-2 14 } 1:2: /14/ :32:29 { shelf-1 slot-2 15 } 1:2: /14/ :32:29 { shelf-1 slot-2 16 } 1:2: /14/ :32:29 { shelf-1 slot-2 17 } 1:2: /14/ :32:29 { shelf-1 slot-2 18 } 1:2: /14/ :32:29 { shelf-1 slot-2 19 } 1:2: /24/ :13:29 { shelf-1 slot-2 20 } 1:2: R

34 Interface profile and power parameters The al-dmt profile The al-dmt profile Introduction In al-dmt profiles, you set parameters to specify the data rate, signal quality and power, and interleaving delay of the interface. The Stinger unit references these parameters in the training process. Discrete multitone (DMT) standards define the fast and interleaved data latencies for each direction (upstream and downstream) of ADSL transmission. Active parameters The following sets of parameters are active for ADSL and ADSL2+ LIMs: Line activation and DMT parameters Rate adaptive mode parameters Power spectral density (PSD) and power-level parameters Fast and interleaved bit-rate parameters Interleaving delay parameters Noise margin parameters Trellis encoding Power back-off Dynamic rate adaptive parameters (Only active with LIMs with ADSL2+ capability) Line activation and DMT parameters Default settings Each direction of traffic (upstream and downstream) on an ADSL-DMT line can have a different minimum and maximum bit rate. Dual latency, which can use both the fast and interleaved channels in both directions, is not currently supported. The following parameters in the AL-DMT profile, shown with their default settings, are associated with basic line activation. Other parameters and sub-profiles are described later.

Enables or disables port redundancy (sparing) and specifies the mode. The default value, inactive, disables LIM port redundancy (sparing). The automatic setting activates automatic sparing for the port. The values of the error threshold parameters specified in the auto-lim-sparing-config:lim-sparing-config [slot number] profile are used. The manual setting deactivates the LIM port and reestablishes the connection on the same port of the spare LIM R

(Not supported for Annex B LIMs). The LIM attempts to train using ANSI T protocol The LIM attempts to train using ITU-T G protocol. Supported only for ADSL2+ LIMs. The LIM attempts to train using the ADSL2 (ITU-T G.992.3) or ADSL (ITU-T G.992.1) protocol. Supported only for ADSL2+ LIMs. The LIM attempts to train using ADSL2+ protocol (ITU-T G.992.5). If this protocol is not supported, then the LIM attempts to train using READSL2 (ITU-T G Annex-L), or ADSL2 (ITU-T G.992.3). Supported only for Annex A ADSL2+ LIMs. The LIM attempts to train using the extended reach READSL2 protocol (ITU-T G Annex L). Avoid enabling only adsl2re. On enabling it, the code internally enables adsl2 as well. The adsl2re is a desired mode at long loops and at specific noisy scenarios. It is not suitable for short loop scenarios. The TAOS protects against this selection R

43 Interface profile and power parameters Parameters that affect line speed Parameters that affect line speed Protocol selection The LIM will automatically detect and configure itself with the correct standard ADSL protocol if the line-code parameter in the line-config subprofile is set to autoselect. This is the optimum setting for LIMs that do not support ADSL2+, and for LIMs that do support ADSL2+ if that capability will not be utilized. Automatic configuration of the line-code for ADSL2+ is described in Examples for configuration of ADSL2+ line codes (p. 4-4). Parameters determined by protocol selection BIN frequency ranges When the ADSL-lite protocol is specified or detected, the line-latency-down and line-latency-up parameters are automatically set to the value interleave. All other al-dmt profile parameters remain the same, regardless of the protocol used. The upstream and downstream start and end bins define the frequency ranges for upstream and downstream data. The frequency for a particular bin is defined as the bin number multiplied by kHz. You must also make sure to adjust the max-bitrate and min-bitrate parameters to match the frequency range defined by the start and end bin numbers. BIN ranges to support Annex M Although the Annex M protocol supports 9 PSD masks, only the EU-64 mask is supported by TAOS at this time. The EU-64 Mask is defined for the frequency range from Khz to 276 Khz. The upstream-end-bin setting can be used to approximate the other 8 masks. In the following table, the "Actual Bin Value" indicates the highest bin used by the mask as specified in the ADSL2 and ADSL2+ standards. The "Recommended" column indicates the value Lucent recommends to approximate each of the other eight masks. Mask Actual Bin Value Recommended EU EU EU EU EU EU R

44 Interface profile and power parameters Parameters that affect line speed EU EU COMMENT: Overlap mode is not supported for this release. Therefore, the downstream band extends from 276 Khz up to 2208 Khz. Bit swapping for optimum performance For optimum performance under most conditions when using ADSL Annex A, bit swapping should be turned on for all interfaces. The following example shows how this can be accomplished for the first interface of a LIM in slot 2. admin> read al-dmt {1 2 1} AL-DMT/{ shelf-1 slot-2 1 } read admin> set line-config bit-swapping = yes admin> write R9.9.1

45 Interface profile and power parameters Power-level parameters Power-level parameters Maximum power level definition Default settings Parameter descriptions Maximum aggregate power level is the maximum output power allowed on the line at the transmitter output. This value is expressed in decibels with reference to one milliwatt (dbm), where zero dbm equals 1 milliwatt. It is defined for both directions. The line-config subprofile parameters, shown with their default values, for configuring power: [in AL-DMT/{ any-shelf any-slot 0 }:line-config] max-aggr-power-level-up = 13 max-aggr-power-level-down = 20 max-power-spectral-density = 40 gain-default = 16-db Important! If you lower the default value, the line consumes less power and has less capacity. The default value is the maximum allowed setting. Parameter max-aggr-power-level-up max-aggr-power-level-down max-power-spectraldensity gain-default Description Not used. Specifies the maximum aggregate power level on the downstream channel. Its effective range is from 8dBm through 20dBm. Important! This setting is not used with the low-power LIM card (STGRCR-LIM-AP-48). This LIM uses minimum transmission power, which cannot be changed. Not used. Important! Downstream power is controlled by changing the settings of the max-aggr-power-level-down parameter. Not used R

47 3 Configuring an ADSL Annex A LIM Overview Purpose This chapter describes the parameter and profiles used to configure the bit-rate, interleave, and delay of the interfaces of an ADSL or ADSL2+ LIM. Adaptive operation is also described. Important! ADSL Annex B LIM is covered in Stinger ADSL Annex B 48-port LIM Guide, and Annex C is covered in Stinger ADSL Annex C 48-port LIM Guide.

48 Configuring an ADSL Annex A LIM Bit-rate, interleave, and delay considerations Bit-rate, interleave, and delay considerations Bit-rate parameters Attainable bit rates Fast-path bit-rate settings Bit-rate parameters specify minimum, maximum, and planned upstream and downstream bit rates for a rate-adaptive connection. Bit rates depend on the physical interface (the line to which the central office equipment (COE) and customer premises equipment (CPE) are connected) and the ADSL interleaved or fast channel. The bit-rate parameter settings control the use of the fast channel for both upstream and downstream traffic. In the current software version, both upstream and downstream traffic must use the same channel. Interleave-path bit-rate settings The bit-rate parameter settings control the use of the interleave path channel for both upstream and downstream traffic. Relationship to line latency setting Interleave vs. delay The line-latency-up and line-latency-down settings in the line-config subprofile determine which channel is used in each direction. For more information, see line-config subprofile parameters (p. 2-6). Data interleaving increases the ability of the system to tolerate noise on the line. However, it also increases the latency (delay) of the data traffic. When using the interleave channel, determine the maximum amount of latency by considering the type of traffic sent on the line. The more tolerant of delay the traffic is, the higher these settings can be R9.9.1
