column OctetString

This object describes 5 attributes of Overhead bits. The
Overhead bits contains the ISDN U interface transceiver 
operations and maintenance functions that are handled by M4,
M5 and M6 bits in the superframe. These bits are described 
as follows:  
act  - start-up bit; this bit is set to binary ONE by the 
       network as a part of the start-up sequence to 
       communicate readiness for layer-2 communication.
dea  - turn-off bit; this bit is set to binary ZERO by the 
       network to communicate to the NT its intention to
       turn off.
febe - Far End Block Error bit; this bit is set to binary
       ONE if there are no error in the superframe and binary
       ZERO if the superframe contains an error.
uoa  - U interface only activation bit; This bit is set to 
       binary ONE if the S/T interface should be activated. 
       Otherwise, this bit should be set to binary ZERO.
aib  - Alarm indication bit; this bit is set to binary
       ONE if the transmission path for D, B1, and B2 channels
       has been established all the way to the local exchange.
       Otherwise, this bit is set to binary ZERO.
