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

3.8
The C/I channel is used for communication between the OCTAT-P and a layer-2 device
(or ELIC), to control and monitor layer-1 functions. The layer-2 device monitors the
layer-1 indication continuously and indicates a change if a new code is found to be valid
in two consecutive IOM frames (double last look criterion).
