Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Note: WAN configurations and IP routing configurations are not shown (for simplicity). Also, serial interfaces require clocking by the DCE device. Encoding (NRZ/NRZI ) on STUN Interfaces must match end device encoding - router defaults to NRZ.
