oT1E1NationalBits

Module: ERI-DNX-OCTAL-T1E1-MIB

OID (symbolic): ERI-DNX-OCTAL-T1E1-MIB::oT1E1NationalBits

OID (numeric): 1.3.6.1.4.1.644.2.4.2.4.1.1.1.15

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 oT1E1NationalBits?

This single-byte field sets the E1 National S-bits, sa8 through sa4, in the NFA byte of odd frames, entered in hex, with a default value of F8. Admins would only touch this for specialized E1 signaling requirements, since changing the reserved bits within this byte triggers configuration error 427. Leaving oT1E1NationalBits at its default 0xF8 keeps the national bits at their standard all-ones setting.
