• Manufacturer Part Number: PEB2045-N
• Description: Memory Time Switch CMOS (MTSC)
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

The SP signals controls the start of the input and output frame. The output frame starts two
before the falling SP edge. However, the rising edge marks the beginning of time-slot 125.
