TFRA08C13 OCTAL T1/E1 Framer
Functional Description
Note: The Concentration Highway Interface Specification, Lucent Technologies Microelectronics Group November
1990 (DS90-124SMOS) defines the transmit path as output to the system interface, and the receive path
as input from the system interface. This document is consistent with that definition.
