SYNCHRONOUS EQUIPMENT SONET MINIMUM CLOCK
- SY01-SMC
Date: April 20, 2002
- INTRODUCTION
The SY01-SMC is an accurate time and frequency source that has been designed as a module level subsystem for easy incorporation into SONET/SDH systems or network elements. The SY01-SMC is an advanced synchronization solution for timing, jitter and wander issues in accordance with specification for SONET Minimum Clock (SMC) given by Bell Core GR-253-CORE and Bell Core GR-1244-CORE.
- Features
A synchronization solution for timing, jitter and wander concerns in a single module. plies with Bellcore GR-1244-CORE and GR-253-CORE for SMC applications. Supports four modes of operation: Locked to Reference 1, Locked to Reference 2, Holdover and Free-run. Accepts reference inputs from two independent sources from 8 k Hz to 77.76 MHz. Provides two outputs 8KHz to 77.76 MHz. Loop filtering utilizing application specific software in the digital signal processor (DSP). Continuously monitors and evaluate input reference signals. Creates a history buffer for Holdover mode operation. Manual or Automatic selection between timing modes. Alarm and status signal. Host interface and JTAG port. Small dimensions of 2.0 x 2.0 x 0.55 inch.
- APPLICATIONS
The SY01-SMC performs clock regeneration as a Synchronous Equipment Clock (SEC), and is particularly designed for SONET equipment and network elements. However, SY01-SMC can be used in any other telemunication equipment where synchronization is necessary if the performance allowed.
