Hi,
Can anyone answer the following questions regarding H.341:
Procedural: 1. What is the status of the document: is it scheduled to become a standard and if yes, when? 2. Is there any mailing lists/discussion forums to get clarifications/suggestions?
Following are the technical questions:
1. In the proposed model (Figure 2), when the entire GW is represented as an interface, what type this interface is? Are RAS/H.225/H.245 represented as a separate ifIndex entries and if yes of what type and what is the ifStack model for them? 2. Should a linkUp/linkDown/coldStart traps be sent for this interface or it is implementation dependent? 3. In the MmTerminalDataCapability textual convention there is no t38fax. How to report the t38?
H.225 in GW: 4. Should the callsignalStatsTable be implemented in the GW? Most (if not all) counters will be incremented for both incoming and outgoing directions. Is this the intention? Which side is considered as "In" and which side is considered as "Out" for GW? 5. Why callSignalConfigT303 and callSignalConfigT3031 do not have a DEFVAL as defined in H225.
RAS in GW: 6. rasConfigurationGatekeeperIdentifier is defined as read-only. As such, it is impossible to remotely configure a desired GK. Shouldn't it be RW? 7. rasConfigurationGatekeeperDiscoveryAddress: the purpose is not clear. Is it a configured (by user) GK address or it is the GK address, resulted from discovery process? In the first case, shouldn't it be RW? 8. rasRegistrationTable : how many entries are in this table for a GW? Just one? 9. rasRegistrationAliasTable : for the GW it is the list of all aliases it registered in the GK? 10. rasRegistrationAliasTable : What is the intention for GW? To keep entry in the table for every call? If yes, how the calls are represented: those, coming from the lan, have the source address of the endpoint and destination of a GW and those, coming from the SCN vice versa? 11. rasConfigurationTable : the description says ".... The number of entries equals to the number of configuration parameters." If the table is indexed by the ifIndex, why the number of parameters is relevant?
H.245 in GW: 12. h245ConfigurationTable : the description says "..The number of entries equals to the number of H.245 stacks in a system.". Why there supposed to be several H.245 stacks in the system? For different versions of H.245? 13. h245CapExchangeStatsTable : is this table applicable for a GW?
Gateway 14.h323GwSystemTable : all entries in the table (except ..LocalTime) are read only. It seems others could be made read-write in order to allow remote changes (like location, contact person, country code). 15. h323GwConfigurationH323Table : h323GwConfigurationH323CallSignalingAddressTag and h323GwConfigurationH323CallSignalingAddress are defined read-only. It seems if they where defined read-write, it would allow change of this address to a non-standard value. Otherwise, they either contain a well-known address or an address which is configured by other means (like RS232). having these entries RW, would allow easy remote management . On the other hand, h323GwConfigurationH323GatekeeperAddressTag and h323GwConfigurationH323GatekeeperAddress are defined as read-write. Isn't it in contradiction with the description of this variable? Why to allow to the user to change the address of the gatekeeper, this GW is registered with? 16. h323GwCapabilitiesPstnTotalPorts : is it the total number of say, E1/T1 ports this GW supports? 17. h323GwConnectionsCommand : why it is read-write? To allow manager to control the call state remotely? In which cases it might be useful? 18. h323GwConnectionsPstnTable : Currently the table contains only an index. What else supposed to be defined there?
Thanks, Michaela
