e3E1NationalBits

Module: ERI-DNX-E3-MIB

OID (symbolic): ERI-DNX-E3-MIB::e3E1NationalBits

OID (numeric): 1.3.6.1.4.1.644.2.4.2.8.1.2.1.10

Node type: OBJECT-TYPE

Type: OneByteField

Access: read-write

Description: Enables E1 National S-bits to be set to zero or one.
This single byte field can be changed to set the values 
of the E1 NFA byte in odd frames as depicted below:

   sa8 sa7 sa6 sa5 sa4 reserved bits
   --- --- --- --- --- -------------
   1    1   1   1   1   0   0   0      = F8 (default)
   
Values should be entered in Hex.  If reserved bits are changed,
an error code (427) will be returned in the command status.

What is e3E1NationalBits?

A hex byte value that sets the E1 national spare bits (Sa4-Sa8) transmitted in the NFA byte of odd frames; the default F8 leaves all spare bits at 1, and an admin only touches this to meet a carrier's specific signaling requirement.
