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

Data Rate
Each IOM channel consists of a total of 32 bits, or four octets: B1 + B2 + D (18 bits) plus
14 overhead bits for monitor and control information (activation/deactivation of OSI
layer-1 and maintenance functions).
The ISDN user data rate is 144 kbit/s (B1 + B2 + D).
The data is transmitted transparently synchronous and in phase in both directions over
the IOM interface using time division multiplexing within the 125 s IOM-2 interface
frame.
Nominal bit rate of data (DD and DU):
Nominal frequency of DCL:
Nominal frequency of FSC:
