Cisco DSLAM Line Card Intermixing

The following sections provide information about how the line cards can be intermixed within each DSLAM:

Cisco 6015 System Line Card Intermixing

The Cisco 6015 chassis supports line card intermixing. However, mixing cards with different types of encoding (ADSL or SHDSL) on the same side of the chassis could result in decreased performance of the loop due to overlapping frequency spectrums. To minimize potential performance degradation in the binder, install ADSL and SHDSL line cards in separate halves of the chassis. For example, if you install 4xflexis on the left side of the chassis (slots 1 to 3), install 8xG.SHDSLs on the right side of the chassis (slots 4 to 6).

Cisco 6100 with NI-1 System Line Card Intermixing

The Cisco 6100 with NI-1 system supports line card intermixing in separate chassis halves. The left half of the chassis comprises slots 1 to 8 and 21 to 28; the right half comprises slots 13 to 20 and 31 to 38.

Note You can intermix only the 4xflexi (CAP mode) and the 4xflexi (DMT mode) in the same chassis half; however, these cannot be intermixed in the same quadrant.

Cisco 6100 with NI-2 System Line Card Intermixing

The 4xflexi is the only line card that can be used in the Cisco 6100 with NI-2 system. You can intermix the 4xflexi (CAP mode) and the 4xflexi (DMT mode) in the same chassis half; however, these cannot be intermixed in the same quadrant.

Cisco 6130 with NI-1 System Line Card Intermixing

The Cisco 6130 with NI-1 system supports line card intermixing in separate chassis halves. The left half of the chassis comprises slots 1 to 8 and 21 to 28; the right half comprises slots 13 to 20 and 31 to 38.

Note You can intermix only the 4xflexi (CAP mode) and the 4xflexi (DMT mode) in the same chassis half; however, these cannot be intermixed in the same quadrant.

Cisco 6130 with NI-2 System Line Card Intermixing

The Cisco 6130 with NI-2 system supports line card intermixing in separate chassis halves. The left half of the chassis comprises slots 1 to 8 and 21 to 28; the right half comprises slots 13 to 20 and 31 to 38. The line card intermixing configurations that are supported in a separate chassis halves are:

4xflexi (CAP mode) and 4xflexi (DMT mode)
4xflexi (CAP mode) and 4xSDSL
4xflexi (DMT mode) and 4xSDSL

Note You can intermix only the 4xflexi (CAP mode) and the 4xflexi (DMT mode) line cards in the same chassis half; however, they cannot be intermixed in the same quadrant.

Cisco 6160 System Line Card Intermixing

The Cisco 6160 chassis supports line card intermixing. The following sections use the terms halves and quadrants. The Cisco 6160 chassis consists of two halves:

First half—Slots 1 to 9 and slots 19 to 27
Second half—Slots 12 to 18 and slots 28 to 34

The Cisco 6160 chassis consists of four quadrants:

Quadrant 1—Slots 1 to 9
Quadrant 2—Slots 12 to 18
Quadrant 3—Slots 19 to 27
Quadrant 4—Slots 28 to 34

Note Slots 18 and 34 cannot contain line cards with different modulation types. For example, if slot 18 contains an 8xDMT line card, slot 34 must contain an 8xDMT or 4xFlexiDMT line card or be empty. If slot 34 contains an 8xG.SHDSL line card, slot 18 must contain an 8xG.SHDSL line card or be empty.

The following sections describe the line card intermixing guidelines for the Cisco 6160.

Guidelines for Intermixing xDSL Line Cards

The guidelines for intermixing line cards in the Cisco 6160 chassis are as follows:

You can intermix different line cards in the same chassis quandrant as long as the line cards use the same modulation type.
You cannot intermix line cards with different modulation types in the same chassis quandrant.

For example, you can install a 4xFlexiDMT line card and an 8xDMT line card in the same chassis quandrant. However, you cannot install a 4xFlexiDMT or 8xDMT line card in the same chassis quandrant as a 4xFlexiCAP line card.

Due to spectral compatibility limitations in the right side configuration of the Cisco 6160 chassis, line card slots 18 and 34 should be configured as specified in Table 8.

Table 8: Cisco 6160 Right Side Configuration Guidelines

Slot 18	Slot 34	Configuration
8xG.SHDSL	8xG.SHDSL	Supported
8xG.SHDSL	ADSL	Not supported
8xG.SHDSL	Empty	Supported
ADSL	ADSL	Supported
ADSL	8xG.SHDSL	Not supported
ADSL	Empty	Supported

Guidelines for Intermixing 8xG.SHDSLs—Cisco IOS Release 12.2(7)DA and Forward

The Cisco 6160 chassis supports up to 16 8xG.SHDSLs installed per chassis while retaining quality of service (QoS). When an 8xG.SHDSL is installed in a quadrant, no ADSL line cards can be installed in that same quadrant.

Figure 1 illustrates the optimal deployment of 8xG.SHDSLs and quadrant intermixing of ADSL line cards in the Cisco 6160 chassis. For example:

If 4 8xG.SHDSLs are installed in the left side of the chassis, only 25 ADSL line cards can be installed in the remaining quadrants.
If 4 8xG.SHDSLs are installed in the right side of the chassis, only 23 ADSL line cards can be installed in the remaining chassis quadrants.

Note Random cell loss might occur if the guidelines for 8xG.SHDSL deployment in a system are exceeded.

Figure 1: 8xG.SHDSL and ADSL LIne Card Intermixing in the Cisco 6160 Chassis

Cisco 6260 System Line Card Intermixing

The Cisco 6260 chassis supports line card intermixing. The following sections use the terms halves and quadrants. The Cisco 6260 chassis consists of two halves:

First half—Slots 1 to 9 and slots 18 to 26
Second half—Slots 12 to 17 and slots 27 to 32

The Cisco 6160 chassis consists of four quadrants:

Quadrant 1—Slots 1 to 9
Quadrant 2—Slots 12 to 17
Quadrant 3—Slots 18 to 26
Quadrant 4—Slots 27 to 32

The following sections detail the line card intermixing guidelines for the Cisco 6260.

Guidelines for Intermixing xDSL Line Cards

The guidelines for intermixing line cards in the Cisco 6260 chassis are as follows:

You can intermix different line cards in the same chassis quandrant as long as the line cards use the same modulation type.
You cannot intermix line cards with different modulation types in the same chassis quandrant.

Guidelines for Intermixing 8xG.SHDSLs—Cisco IOS Release 12.2(7)DA and Later

The Cisco 6260 chassis supports up to 16 8xG.SHDSLs installed per chassis while retaining QoS. When an 8xG.SHDSL is installed in a quadrant, no ADSL line cards can be installed in that same quadrant.

Figure 2 illustrates the optimal deployment of 8xG.SHDSLs and quadrant intermixing of ADSL line cards in the Cisco 6260 chassis. For example:

If 4 8xG.SHDSLs are installed in the left side of the chassis, only 21 ADSL line cards can be installed in the remaining quadrants.
If 4 8xG.SHDSLs are installed in the right side of the chassis, only 24 ADSL line cards can be installed in the remaining chassis quadrants.

Note Random cell loss might occur if the guidelines for 8xG.SHDSL deployment in a system are exceeded.

Cisco 6015 I/O Module and NI-2 Card Compatibility
Cisco 6160 I/O Card and NI-2 Card Compatibility
Cisco 6260 I/O Module and NI-2 Card Compatibility

Note The Cisco 6100 and Cisco 6130 have only one type of I/O card available; therefore, they are not listed in the following sections.

The I/O cards and I/O modules require a minimum version of the IOS and network management software to operate properly. If your NI-2 card requires a later version of the software, install the later version. For minimum software and network management requirements for the NI-2 cards, see the "Cisco DSLAM and NI-2 Card Compatibility" section.

Cisco 6015 I/O Module and NI-2 Card Compatibility

Table 12 lists the Cisco 6015 I/O modules, their associated product numbers, and minimum software and network management requirements for the I/O modules. Both Cisco 6015 I/O modules are compatible with the DS3+T1/E1 IMA, ITEMP DS3+T1/E1 IMA, or OC-3c/OC-3c NI-2 card.

Note The I/O module does not function when you use an OC-3c/OC-3c NI-2 card in the Cisco 6015; however, an I/O module must be installed in the chassis for the system to operate correctly. The OC-3c/OC-3c NI-2 card does not support the DS3, E1, or T1 interfaces found on the front of the I/O modules. Therefore, the trunk and subtending interfaces are provided on the front of the OC-3c/OC-3c NI-2 card.

The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority level 2; these classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will automatically open a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following URL:

Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). In addition, please have available your service agreement number and your product serial number.
