OSC_EN

4096 channel x 4096 channel non-blocking digital

Time Division Multiplex (TDM) switch at

8.192 Mbps and 16.384 Mbps or using a

combination of ports running at 2.048, 4.096,

8.192 and 16.384 Mbps

32 serial TDM input, 32 serial TDM output

streams

Integrated Digital Phase-Locked Loop (DPLL)

exceeds Telcordia GR-1244-CORE Stratum 4E

specifications

Output clocks have less than 1 ns of jitter (except

for the 1.544 MHz output)

DPLL provides holdover, freerun and jitter

attenuation features with four independent

reference source inputs
