For Immediate Release: CXR/Larus Announces New 54581 Timing Insertion Unit Allows Legacy Telephone Equipment to be Timed to Stratum 1 Standards
This innovative module, when installed in a StarClock TM 200 Synchronization Timing System, is used to provide timing on two separate DS1 circuits, with either D4 or ESF framing. It recovers timing from the traffic-bearing DS1 circuit, and clocks the data into a first-in, first-out buffer with inventive self centering circuitry to absorb up to 28 Unit Intervals (UIs) of jitter and wander, synchronously buffer one frame (192 bits) from the input signal, and supply a re-timed signal referenced to a 1.544 Mbps input. The primary application of the Model 54581 module is to provide legacy telephone equipment which does not have an external timing reference input Stratum 1 level timing on the incoming DS1s. This avoids the costly forklift upgrading of equipment when deploying timing sensitive services such as VoIP. The Model 54581 Timing Insertion Unit may also be used to provide timing to a T1 link where both ends of the circuit are looped timed. The timing is extracted from the reference input, which is supplied from the office synchronization and timing system. Wander and Jitter may also be removed when the card is used in synchronous applications. Up to 10 of the Model 54581 Timing Insertion Units can be installed into the StarClockTM 200 shelf, providing the re-timing of up to 20 individual DS-1 circuits. About CXR/Larus CXR/Larus Corporation is comprised of three telecommunication units of EMRISE Corporation, an international manufacturer of defense and aerospace electronic components, subsystems and telecommunications equipment with operations in the US, France, UK and Japan. Together, these business units combine common technologies and markets to develop transmission and network access products, timing and synchronization systems, and test instruments for a global marketplace. The focus is on providing equipment to meet the emerging requirements for voice, data and video transport, synchronization and timing, and testing for public and private networks.
