ISDN will still be around for quite a while as there are still a lot of place where you can't get either DSL nor Cable.
Additionally it is often used for backup lines when a leased one goes down.Working on CCNP: [X] SWITCH --- [ ] ROUTE --- [ ] TSHOOT

If a CO is provided for ISDN couldn't the same CO be used for DSL technology? -

No.
Running DSL requires that the lines attenuation does not exceed specified limits. If the line is too long (the CO is too far away from the PoP) you simply cannot run DSL.Working on CCNP: [X] SWITCH --- [ ] ROUTE --- [ ] TSHOOT
