Service access capabilities and method used to process client services in ODU1 convergence mode


TOA, THA, and TOM boards support ODU1 convergence mode. In this mode, each ODU1 signal is divided into 16 timeslots, each of which occupies 155 Mbit/s bandwidth. Client services are sliced into 155 Mbit/s fragments and mapped into ODU1 signals. In this way, multiple low-rate services are converged into one ODU1 signal, improving bandwidth usage. For example, GE services occupy 7 timeslots, STM-1 services occupy 1 timeslot, and FC100 services occupy 6 timeslots. All the preceding services can be transmitted together in one ODU1 signal.

Method used to query the service mode and set the IPTV mode
The IPTV mode needs to be enabled only when the host service is IPTV. The command for enabling the IPTV mode can be executed only on the primary controller. The IPTV service refers to the video on demand (VOD) and recording services. The database is not the IPTV service. 1. Query the service mode. Log in to the CLI and run showservicemode to query the service mode. 2. Set the IPTV mode. Log in to the CLI and run setservicemode -m 1 to enable the IPTV mode. Note: The IPTV mode needs only to be enabled on one controller. After the IPTV mode is enabled, run resetsys to restart the system for the IPTV mode to take effect. 3. Restart the system as follows: OceanStor: admin > resetsys
