Cell Rate Margin: This is a measure of the difference between the effective
bandwidth allocation and the allocation for sustainable rate in cells per second.

Cell Relay Service: A carrier service which supports the receipt and transmission
of ATM cells between end users in compliance with ATM standards and
implementation specifications.

Convergence Sublayer: The general procedures and functions that convert between
ATM and non-ATM formats. This describes the functions of the upper half of the
AAL layer. This is also used to describe the conversion functions between non-
ATM protocols such as frame relay or SMDS and ATM protocols above the AAL
layer.

CTD
Cell Transfer Delay: This is defined as the elapsed time between a cell exit event
at the measurement point 1 (e.g., at the source UNI) and the corresponding cell
entry event at measurement point 2 (e.g., the destination UNI) for a particular
connection. The cell transfer delay between two measurement points is the sum of
the total inter-ATM node transmission delay and the total ATM node processing
delay.
