 OTSiA and Service Media Channel (Separation)
‣ T17-SG15-180129-TD-WP3-0125!R1!MSW-E (Draft G.Media Discussion)

‣ 6 Functional architecture of optical media

‣ The functionality of the optical media consists of constructs that can carry/propagate optical signals as well as elements that can operate on optical waves (e.g., filters). A key
result of arranging and configuring these elements is the construction of network media channels, each of which can support an OTSi. The structure of an optical media network
is provided in Figure 6-1 below.
‣ [Editor note: needs further review.]
‣ Optical tributary signals (OTSi) are each characterized by their central frequency and an application identifier (see [ITU‑T G.698.2]). The OTSi is depicted by the optical signal
modulator/demodulator, as shown in Figure 5‑1.
‣ Below the OTSi are the media constructs that provide the ability to configure the media channels (see clause 7.1.2). The nominal central frequency and width of a media channel
is defined by its frequency slot (as defined in [ITU‑T G.694.1]). Each OTSi is guided to its destination by an independent network media channel.
‣ Media channels must be configured before any OTSi can be carried. The effective frequency slot of a media channel is defined by the filters that are in the path of the media
channel. The effective frequency slot may be sufficient to support more than one OTSi.
‣ The media constructs and media element are described in clause 7, the OTSiA is described in clause 10.
‣ An application identifier includes the application codes defined in the appropriate optical system Recommendations, as well as the possibility of proprietary identifiers. The
identifier covers all aspects of the signal, including forward error correction, baud rate and modulation type.
‣ A media channel that may carry multiple OTSi may be used to provide what is commonly called an "express" channel.

‣ 8.1 Assignment of signals to media channels

‣ A media channel may be configured before it has been decided which OTSi will be allocated to it. As described in clause 7.1.2 the OTSi must be compatible with the
network media channel that has been assigned.

‣ T17-SG15-180129-TD-WP3-0125!R1!MSW-E (Draft G.Media Discussion)
‣ 10.1 Management of OTSiA connections
‣ From a management control perspective, a request to carry an OTSiA should be considered as a single action. This action involves the configuration of the OTSi
modulator and demodulator, the network media channels and the OTSiG‑O. Configuration of the network media channels includes the configuration of the media
elements that encompass the media constructs (e.g., media subnetworks, As described above, the network media channel may be fully or partially configured
before the OTSiA connection request is received.
‣ flexible grid capable filters and possibly amplifiers) that are part of the serial concatenation of media channels that forms the network media channel.
‣ Two simple cases for the configuration of a network element that includes a media subnetwork when an OTSiA connection request is received are described below:
‣ 1) Pre‑configured media elements: In this case the media channels in the media subnetwork and the associated filters are configured before the OTSiA connection
request is received:
‣ • The OTSiG‑O connection function and the OMS‑O MSI are configured.
‣ • The media channel(s) in media subnetwork must be checked to verify that the correct ports are connected so that all members of the OTSiG are directed to and or
from the same OMS media port. The associated filters are checked to ensure that frequency slot of each filter is compatible with the frequency slot requested for
each OTSi.
‣ • In general when the OTSiA is deleted, only the OTSiG‑O connection and OMS‑O MSI (for that OTSiG) should be removed, the configuration of the media elements
should not be changed.
‣ or:
‣ 2) The media elements are not configured:
‣ • In this case, the media channels in the media subnetworks and filters are configured as a result of the OTSiA connection request. The media channels in the media
subnetwork and the associated filters, the OTSiG‑O connection and the OMS‑O MSI are configured. The consistency checks described above should be performed.
‣ • In general, deletion of the OTSiA should also result in the deletion of the OTSiG‑O connection the OMS‑O MSI. The media subnetwork and filter media channels
should also be deleted, except in the case where a media channel is being used to support another network media channel.

 Question

‣ How do we place OTSiA and Network Media Channel together?

• Do we define OTSiA layer and another layer for the photonic
• Use Inverse muxing model (it is a group that we want to represent)
• ITU model show “coordination”

30 | Infinera
 SMC and NMC (Disaggregated model)

‣ In a Disaggregated model, the transmitter are independent to the Optical Transport

Network (Open Line System)
‣ The Controller want to create SMC service that could carry OTSi in NMC
‣ SMC/NMC could have their own OAM
• At least for monitoring of SMC
• SMC-O or SMCG-O, if using one-to-one relation with OTSiA, then it is redundant
(OTSiA and SMCA are the path representation in the ITU Photonic OAM
• If not one-to-one, then a stacking will be needed at the edge of the photonic network
(OTSiG-O/SMCG-O/OMS-O/OTS-O) but not after (SMCG-O/OMS-O/OTS-O). Path
Failure could be pass from share SMCA to OTSiA.
‣ OTSiA could have relation to a group of OTSi and NMC id
‣ SMCA could have relation to a group of SMC id
