Mode
This sets the Central Office Compatibility option to ANSI (complies with
the requirements specified in Bellcore TR-TSY-000194 and adopted by
ANSI — the American National Standards Institute) or AT&T (complies
with the requirements specified in AT&T PUB 54016). These publications
define, in part, the manner in which signal quality or performance mea-
surements are determined, transmitted, and responded to. The ANSI
mode supports Bellcore Scheduled Performance Report Messages (PRMs)
and Unscheduled Messages, messages initiated by the Telco and con-
tained in the Data Link subchannel provided in ESF framing. The
A T & T mode supports their Telemetry Asynchronous Block Serial Proto-
col (TABS), a maintenance message protocol initiated by the Telco and
contained in the Data Link subchannel provided in ESF framing. This
option applies only when ESF on the network side is selected for the
Frame Format option. The default setting is ANSI. (This option is also
set via option switch S7-8.) (In Unframed Mode, this function does not ap-
ply and is removed from this screen.)
