Rec. ITU-T G.988 (2012)/Amd.2 (06/2016) 1

Recommendation ITU-T G.988

ONU management and control interface (OMCI) specification

Amendment 2

1) Clause 2, References

In clause 2, add the following references in appropriate order:

[ITU-T G.997.2] Recommendation ITU-T G.997.2 (2015), Physical layer management for

G.fast transceivers.

[ITU-T G.9700] Recommendation ITU-T G.9700 (2014), Fast access to subscriber terminals

(G.fast) – Power spectral density specification.

[ITU-T G.9701] Recommendation ITU-T G.9701 (2014), Fast access to subscriber terminals

(G.fast) – Physical layer specification.

2) Clause 9.8.1, Physical path termination point CES UNI

In clause 9.8.1, replace the existing text for CES loopback configuration as follows:

CES loopback configuration: This attribute specifies and reports the loopback configuration

of the physical interface.

0 No loopback

1 Payload loopback

2 Line loopback

3 OS-directed loopback 1 (loopback from/to PON side)

4 OS-directed loopback 2 (loopback from/to CES UNI side)

5 OS-directed loopback 3 (loopback of both PON side and CES UNI

side)

6 Manual button-directed loopback (read only)

7 Network-side code inband-directed loopback (read only)

8 SmartJack-directed loopback (read only)

9 Network-side code inband-directed loopback (armed; read only)

10 Remote-line loopback via FDL

11 Remote-line loopback via inband code

12 Remote-payload loopback.

Upon ME instantiation, the ONU sets this attribute to 0. (R, W) (mandatory)

(1 byte)

3) Clause 9.12.18, OpenFlow config data

Add the following new ME clause 9.12.18 to clause 9.12 as follows:

9.12.18 OpenFlow config data

This managed entity contains the configuration data whose underlying transport method is OpenFlow.

Instances of this managed entity are created and deleted by the OLT.

2 Rec. ITU-T G.988 (2012)/Amd.2 (06/2016)

Relationships

An instance of this managed entity is associated with each instance per OpenFlow

transportation channel. There might be more than one OpenFlow transportation channel per

ONU.

Attributes

Managed entity ID: This attribute uniquely identifies each instance of this managed entity.

(R, set by create) (mandatory) (2 bytes)

TP type: This attribute specifies the type of ANI-side termination point associated

with this managed entity.

1 GEM interworking TP

(R, W, set by create) (mandatory) (1 byte)

TP pointer: This attribute points to the instance of the TP associated with this

OpenFlow configuration data. The type of the associated TP is determined

by the TP type attribute. (R, W, set by create) (mandatory) (2 bytes)

Version: This integer attribute reports the version of the OpenFlow protocol in use.

The ONU should deny an attempt by the OLT to set or create a value that

it does not support. The value 0 indicates that no particular version is

specified. (R, W, set by create) (mandatory) (1 byte)

D/S OpenFlow message: This attribute specifies the D/S OpenFlow message which is carried

over the OMCC channel. (R, W) (mandatory) (24N bytes)

D/S forwading control: This Boolean attribute indicates the current D/S OpenFlow message

is ready to be sent (true) or not. The default value is false. (R, W) (mandatory)

(1 byte)

D/S receiving status: This Boolean attribute indicates the ONU is ready to accept a new

downstream packet (true) or not. The default value is false. (R) (mandatory)

(1 byte)

U/S OpenFlow message: This attribute specifies the U/S OpenFlow message which is carried

over the OMCC channel. (R, W) (mandatory) (24N bytes)

U/S receiving control: This Boolean attribute controls the current U/S OpenFlow message is

dafely received (true) or not. The default value is false. (R, W) (mandatory)

(1 byte)

U/S forwarding status: This Boolean attribute reports the current U/S OpenFlow message is

ready to be sent (true) or not. The default value is false. (R) (mandatory)

(1 byte)

Circuit ID: This attribute identifies the first access information of the user

(R, W) (Optional) (24N byte)

Remote ID: This attribute identifies the second access imformation of the user as an

addition identifier to circuit ID. (R, W) (Optional) (24N byte)

Administrative state: This attribute locks (1) and unlocks (0) the functions performed by the

MPLS pseudowire TP. Administrative state is further described in

clause A.1.6. (R, W) (optional) (1 byte)

Operational state: This attribute reports whether the managed entity is currently capable of

performing its function. Valid values are enabled (0) and disabled (1). (R)

(optional) (1 byte)
