Verify the Cisco 6260 Cabling

The Champ connector pinouts on the back of the Cisco 6260 chassis are mapped for octal-port xTU-C

line cards. Verify that industry-standard unshielded twisted pair (UTP) 50-pin Champ cables are

currently used in your configuration. If you are making your own cables or using another type of cable,

see the

mapping information.

Remove the 4xflexis

Verify that a total of two Corning 120 POTS splitters are installed in the rack.

Remove the current Corning 120 POTS splitter and install an ADC Broadwire 240 POTS splitter.

For installation procedures for each POTS splitter, refer to the appropriate

third-party documentation.
