T1/E1 Receive Status Register
Access
Address
Reset Value
Each bit in the framer receive status register declares a specific condition dependent on
the selected modes. The following convention applies to the individual bits:
0
1
The change of status bit (except FSRF) can also be used to generate a framer interrupt
vector. See also register IMR which describes how to enable/disable interrupt vector
generation and refer to the description of framer interrupt vector on page

No Multiframe Found
E1: CRC-4 Interworking
This bit is set, if no multiframe is found after 400 milliseconds.
Loss of Signal (Red Alarm)
This bit is set, when the ’Loss of Signal’ condition has been detected.
T1
Detection
An alarm will be generated if the incoming data stream remain at logical
zero for 168 cycles.
Recovery
The recovery procedure starts after detecting a logical 1. The LOS alarm
is cleared if 21 one’s are detected within 168 bits (12.5%).
