## OID : `1.3.6.1.2.1.10.133.1.8.5.1.1`

```asn1
{iso(1) identified-organization(3) dod(6) internet(1) mgmt(2) mib-2(1) transmission(10) optIfMibModule(133) optIfObjects(1) optIfODUk(8) optIfGCC12ConfigTable(5) optIfGCC12ConfigEntry(1) optIfGCC12Codirectional(1)}
```

### Description

```asn1
optIfGCC12Codirectional OBJECT-TYPE
SYNTAX TruthValue
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"Indicates the directionality of the GCC12 termination with respect to the associated ODUk CTP. The value true(1) means that the sink part of the GCC12 extracts COMMS data from the signal at the input to the ODUk CTP sink and the source part of the GCC12 inserts COMMS data into the signal at the output of the ODUk CTP source. The value false(2) means that the sink part of the GCC12 extracts COMMS data from the signal at the output of the ODUk CTP source and the source part of the GCC12 inserts COMMS data into the signal at the input of the ODUk CTP sink. This attribute may assume either value when the corresponding instance of optIfODUkTtpPresent has the value false(2). When the value of the corresponding instance of optIfODUkTtpPresent is true(1) then the only value allowed for this attribute is true(1)."
