1. u-LAW TRANSMISSION PARAMETERS
1.01
The tables in this part provide the transmission requirements which
Meridian SL-1 is
destgned
to meet or exceed in
M-Law
applications.
The specified performance applies in the temperature range of 0 to
50°
C.
1.02 Unless otherwise specified. all specifications are stated in terms of
being met
by
95%
of connections.
