If the tandem is operated by the ILEC - as tandems are wont to be - any tandem access and/or switching charges will come from the ILEC, one would assume. On 07/22/2010 05:06 PM, CLEC NY wrote:

Hi,

Pardon me if this is really a dumb question.

I need to know in following scenario, when call is coming from IXC location -> CLEC end user ( replace Company with CLEC in picture. ) Who send bills for "Tandem switching charges" to IXC? CLEC or ILEC? In this case Tandem switch is owned by ILEC.

Under switched access servies ,I know CLEC will charge for Common Trunk Port ( CTP) , Local switching , Local Trunk trasport / facility , Tandem transport, but Tandem switching is questionable.

Sorry about crude picture...

Thanks & Regards, Naush.
