dsx1TestUsrDefLoop

Module: ERI-DNX-LINK-TEST-MIB

OID (symbolic): ERI-DNX-LINK-TEST-MIB::dsx1TestUsrDefLoop

OID (numeric): 1.3.6.1.4.1.644.2.4.5.1.1.1.21

Node type: OBJECT-TYPE

Type: UserDefFormat

Access: read-write

Description: The user defined loop provides the length and value options for activating as well as deactivating the loop. The format is represented using an IP address syntax (4 byte string).

The 1st byte signifies the Activate loop code bit length (4-7) The 2nd byte represents the Activate loop code value (0-255) The 3rd byte signifies the Deactivate loop code bit length (4-7) The 4th byte represents the Deactivate loop code value (0-255)

The default Loop format is 5.8.6.36: Activate : 5 bits (length) 00001000 (decimal value = 8) Deactivate: 6 bits (length) 00100100 (decimal value = 36)

Notes: - Loop code uses 4,5,6 or 7 high order bits of the code value. - Bit 7 is transmitted first. - Unframed code overwrites the framing bits.

What is dsx1TestUsrDefLoop?

Defines the custom activate/deactivate loop-up code for a user-defined loop, packed into a 4-byte IP-address-style value: bit-length and value for the activate code, then bit-length and value for the deactivate code (default 5.8.6.36). An admin sets this when the standard loop codes don't match the far-end equipment's expected loop-up sequence.
