1.2 Features
z
DMA Read and Write
Uses the DMA technology based on PCI bus to read and write data, greatly reducing
the CPU cost.
z
E1/T1/J1 Support
Provides an easy selection of the E1, T1 or J1 trunk and its matching impedance via
software reconfiguration, not requiring any change in hardware.
z
Signaling Interface
SS1 provides two levels of interfaces respectively for MFC transmission/receipt and
SS1 connection; SS7 provides two levels of interfaces respectively for MTP and
TUP/ISUP, meeting various customer requirements.
z
Signaling Processing
Installed with loadable signaling processing modules, each board supports SS1, SS7
and ISDN, eliminating the need for extra signaling boards. The signaling processing
program can be upgraded via a simple software configuration, without having to
change the hardware.
z
Signaling Links
Each board supports up to 8 signaling links and the signaling hot-backup feature, i.e.
the signaling can be processed by the standby server whenever something is wrong
with the links being used, which increases the flexibility and reliability in a great
extent. All the timeslots ranging from 1 to 31, not only TS16, can be used for SS7 and
ISDN signalings.
z
Programmable Tone Detector
Detects single or dual tones at any frequency, offering facility for use with a variety of
PBXes and key telephone systems.
z
Software-based Terminal Matching
A single board supports several kinds of trunks which differ in impedance. They are
100
Ω
T1, 110
Ω
J1 and 120
Ω
E1 twisted-pair cables and 75
Ω
E1 coaxial cable. Both
transmit and receive terminals on the board are specified via software configurations,
facilitating easy connections to a variety of digital trunks and optical transceivers.
