Alarm reporting and performance monitoring per
AT&T,
ANSI,
ITU-T, and ETSI standards.
Facility data link features:
— HDLC or transparent access for either ESF or
DDS + FDL frame formats.
— Register/stack access for
SLC-96
transmit and re-
ceive data.
— Extended superframe (ESF): automatic transmis-
sion of the ESF performance report messages
(PRM). Automatic transmission of the
ANSI
T1.403 ESF performance report messages. Auto-
matic detection and transmission of the
ANSI
T1.403 ESF FDL bit-oriented codes.
— Register/stack access for all CEPT Sa-bits trans-
mit and receive data.
HDLC features:
— HDLC or transparent mode.
— Programmable logical channel assignment: any
time slot, any bit for ISDN D-channel, also inserts/
extracts C-channels for V5.1, V5.2 interfaces.
