Aside from the fact that "a CPE" is grammatically incorrect, you are also semantically wrong. A router is any device connected to multiple networks that can forward packets between them; and consumer-premises equipment includes everything that's directly connected or consumes a service from a telecom provider. Landline phones, set-top boxes and satellite decoders are also examples of CPE.

It's like me stating "you're not a man, you're a human!" and then expecting you to be in awe of my profound wisdom.
