4 Regulatory

Requirements

Due to the enormous cost of interrupted service and failed network equipment, telephony

service providers have adopted various specifications to help regulate the reliability and

performance of the telecommunications products that they purchase. In Europe and much

of the Far East, the most common standards are ITU-T K.20 and K.21. In North America,

most operating companies base their requirements on GR 1089, TIA-968 (formerly known

as FCC Part 68), and UL 60950.

Note: This section is a paraphrase of existing documents and does not cover the listed

regulatory requirements in their entirety. This information is intended to be used only

as a reference. For exact specifications, obtain the referenced document from the

appropriate source.
