Port Block
The Port Block always precedes a Mode Block. This Block contains all the
necessary parameters to link the PBX/Telephone system with the SVMi
series. This includes all call setup protocols, hardware communication
processes, handshaking, and switch integration. The Block tells the physical
port how to communicate with the hardware it is connected to.
The Port Block defines the physical connection between a SVMi series voice
port and the phone system, describing all the signals passed between the
phone system and SVMi series. It describes how calls are presented, how to
answer them, and how to collect integration data describing an incoming call.
It defines the necessary dial strings to place callers on consultation hold and
draw dial tone, complete call transfers, abort call transfers, log on, and
disconnect. The Port Block also defines what kind of disconnect supervision
the phone system provides and how reliable it is.
The Port Block answers incoming calls and checks the Schedule Table to
find out which Mode Block to pass control to. The Block collects the Call
Type Data and passes that data to the appropriate Mode Block along with
the caller.
In order to process calls, each port must be assigned a Port Block.
This has been done for you and is hard coded into the system.
Many of the parameters are not applicable to the Samsung switches
while in an embedded environment. The Port Block was made visible
to allow you to adjust the Disconnect Parameter. Many installations
have been having trouble getting the CO to provide proper
disconnect. Changing the disconnect signal in the port block will
allow the OfficeServ System to disconnect on an alternate signal
type. See Disconnect Signal below.
Parameters prefixed below with (DO NOT USE) should not be
played with. These parameters will ultimately be adjusted for use
with the Samsung switches or eliminated from view.
