Preliminary specification
Universal Timeslot Interchange
SC4000
FEATURES
• Timeslot interchange between local
and expansion buses
• Architecture optimized for call pro-
cessing environments: SCbus™,
MVIP® and ST-BUS Compatible
• Full switching between any of:
– 128 local bus input SI timeslots
– 128 local bus output SO timeslots
– up to 2048 expansion bus SD
timeslots
• Multiple local bus speeds and
formats:
– 2.048, 4.096 or 8.192 Mb/s
– PEB®, STbus or GCI
• Supports both Intel® and Motorola®
processor interfaces
• Serial or parallel access to expansion
bus
• Enhanced input hysteresis threshold
• Internal phased lock loop
• Fast response and support for SCbus
clock fallback
• Flexible local frame sync interface
• Supports hyper channel capability
(bundling)
• SCbus message bus interface and local
loopback control
• High availability and self-diagnostic
features
• 5V CMOS technology
• 100-pin TQFP package
APPLICATIONS
• PC-based switching
• Small to medium size digital switch
matrices
• SCbus/MVIP interface functions
• Digital centralized voice processing
system
