• Manufacturer Part Number: PEB2096
• Description: Octal Transceiver for UPN Interfaces OCTAT-P
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

The PEB 2096, OCTAT-P, is equipped with a digital ISDN Oriented Modular (IOM-2)
interface, for communication with upper layer functions, such as IDEC (PEB 2075), EPIC
(PEB 2055) and ELIC (PEB 20550). EPIC and ELIC represent the first switching stage
towards the exchange system. Refer to figure 7.

2.2.2
The IOM interface is a four-wire serial interface with a data clock (DCL), an 8 kHz frame
synchronization clock (FSC), and one data line per direction: data downstream (DD) and
data upstream (DU). One IOM-2 frame consists of up to 8 IOM channels (subframes)
(figure 8).
