MG-COT in the System
Note:
For Proprietary Protocol mode, Internal PHI-BRI controls the signaling data, which is accommodated in
the Telephony Server. Call control between Internal PHI-BRI and MG-COT is executed via TCP/IP port of
the system.
In some cases, signaling data can be controlled by SP-PHI even though MG-COT operates in Proprietary
Protocol mode. For the detail, refer to “Consideration for SP-PHI Data Assignment” in Data Program-
ming Manual - Business.
Note:
For SIP mode, SP-PHI, which is accommodated in MPH (Multi Protocol Handler) of the Telephony Server,
handles the control signal from/to MG-COT. MPH is the interface for the control signal. Call control be-
tween SP-PHI and MG-COT is executed via TCP/IP port of the system.
