ISDNTELCTL(8) System Manager's Manual ISDNTELCTL(8) NAME isdntelctl - control isdn4bsd telephone sound format conversion SYNOPSIS isdntelctl [-c] [-g] [-u unit] [-A] [-U] [-N] DESCRIPTION isdntelctl is part of the isdn4bsd package and is used to configure the sound format conversion facilities of the /dev/isdntel interfaces. The following options are available: -c Clear the telephone input queue. -g Get the sound format currently in use. -u Set the /dev/isdntel unit number. The default value is zero to access device /dev/isdntel0. -A Do A-law (ISDN line) -> mu-law (userland) conversion. -U Do mu-law (ISDN line) -> A-law (userland) conversion. -N Set sound conversion to do no format conversion. The telephony data stream comes out of the line in a bit-reversed format, so the isdntel(4) driver does the bit-reversion process in any case. Additionally, the user can specify to do A-law to mu-law, mu-law to A-law or no conversion at all in the isdntel driver by using the isdntelctl utility. FILES /dev/isdntel<n> EXAMPLES The command isdntelctl -g displays the currently used sound format for device /dev/isdntel0. SEE ALSO isdntel(4), isdnd.rc(5), isdnd(8) STANDARDS A-law and mu-law are specified in ITU Recommendation G.711.
