Overview

SYNCHRONY® ST products put network service providers back in control of the
balance between minimized costs and optimized performance.
The products, which include the ST-1000 and ST-20, provide the opportunity to
compete effectively while increasing responsiveness to customer and user demands
and their differing Quality of Service needs.

ST products permit the best networking technology to be deployed for each
application. No compromise is necessary when selecting a circuit, frame, or cell
transport technique. Spare bandwidth is dynamically allocated to both bursty traffic,
as well as contending voice, video, or other constant bit rate traffic, to ensure
maximum effectiveness of the available resources.

Each of your users or customers can establish service level agreements, with
maximum performance achievable for LAN-derived traffic, while the time-critical
network demands of voice and legacy data are assured.
ATM migration is reduced to the tactical decision level, being accomplished through
SYNCHRONY® Cell Exchange CX-1500/CX-1540 where ATM service is available.

Multiple service offerings extend from voice, video, image and data through full LAN
capability including routing, bridging and strong SNA functionality including support
for DLSw, LLC2 conversion and Source Route Translation.

Intelligent voice handling and switching capabilities include support of DPNSS,
Q.Sig and Q.931 call switching and standard DTMF. Compression options are
soft-configurable, per circuit and include ADPCM, ATC (Adaptive Transform
Coding), CELP (Code Excited Linear Prediction), and the low delay, award winning
ECELP (Enhanced CELP) that provides packetized voice services with compression
rates as low as 4.8 kbps.
