Cisco 6260 System Overview
1.2.3.8.1 Guidelines for Intermixing xDSL Line Cards
Mixing line cards of different modulation types in the same quadrant of any Cisco DSLAM is prohibited.
Different modulation types are allowed in the same half of a chassis with the exceptions of slots 18 and
34 in the Cisco 6160 beginning with Cisco IOS release 12.2(7)DA. Mixing line cards of the same
modulation type (for example, 4xFlexiDMT and 8xDMT line cards) in a quadrant is allowed.
1.2.3.8.2 Guidelines for Intermixing 8xG.SHDSLs—Cisco IOS Release 12.1(7)DA2, 12.2(1b)DA, and 12.2(5)DA
The Cisco 6260 chassis can be fully populated with 8xG.SHDSLs while retaining QoS, as long as the
upstream bandwidth is provisioned at a maximum of 5 Mbps for even ports and a maximum of 5 Mbps
for odd ports per line card. Once an 8xG.SHDSL is installed in a chassis quadrant, no ADSL line cards
can be installed in that same quadrant.
1.2.3.8.3 Guidelines for Intermixing 8xG.SHDSLs—Cisco IOS Release 12.2(7)DA and Later
The Cisco 6260 system supports up to 16 8xG.SHDSLs installed per chassis while retaining QoS. Once
an 8xG.SHDSL is installed in a quadrant, no ADSL line cards can be installed in that same quadrant.

illustrates the optimal deployment of 8xG.SHDSLs in the Cisco 6260 chassis with quadrant
If 4 8xG.SHDSLs are installed in the left side of the chassis, only 21 ADSL line cards can be
installed in the remaining chassis quadrants.
No ADSL line cards can be installed in the same quadrant as the 8xG.SHDSLs.
Note
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.
No ADSL line cards can be installed in the same quadrant as the 8xG.SHDSLs.
