Cisco Cisco 6015 IP DSL Switch

The 8xDMT over ISDN line card is supported in chassis halves in the Cisco 6015 DSLAM and in chassis 
quadrants in the Cisco 6260 DSLAM. If a chassis section (half or quadrant) contains 8xDMT over ISDN line 
cards, you can install other types of supported line cards in other chassis sections; however, you can install 
only 4xDMT over ISDN (Annex B) line cards in the same section as the 8xDMT over ISDN line cards. 

See the 

 for information about operating requirements for Alcatel-based CPEs 

and Cisco SOHO 76 and 826 CPEs. 

Use line lengths greater than 100 meters.

Provision the maximum downstream rate to 7616 kbps or less.

Modes 0, 1, and 2 are not supported. Only framing mode 3 is supported.

Do not remove the data line from the CPE modem while voice traffic is present because the ISDN line 
could momentarily drop and terminate the voice line.

Do not select a zero interleaving delay parameter because that parameter is likely to create a high-bit 
error rate with long loops. Use the default parameter.

Bit swapping is not supported.
