It has data rates up to 512 kbit/s and is interoperable with the KG-84, KG-84A, and KG-84C data encryption devices.

Versions
Several versions of the KIV-7 have been developed over the years by many different corporations that have either bought the rights to build the KIV-7 or through corporate mergers.

KIV-7 		Speeds up to 512 kbit/s
KIV-7 HS	Speeds up to T-1 (1.54 Mbit/s)
KIV-7HSB	Speeds up to 2.048 Mbit/s
KIV-7M		Speeds up to 50 Mbit/s and supports the High Assurance Internet Protocol Interoperability Specification (HAIPIS)
