Setting the Calling Party Identification Pad String
Setting the Calling Party Identification
Pad String
The Message Center Interface (MCI) protocol, used by the NEAX 2400 switch to
communicate with the SID, provides calling and called party information
consistent with the dial plan administered on the switch. The SID operates on
Simplified Message Desk Interface (SMDI) protocol which uses a seven-digit
field. To compensate for the difference between the MCI and SMDI protocols, the
SID uses a seven-digit string, called the Calling Party Identification Pad (CPID)
string, that the SID overwrites with caller identification information. The SID
assigns the field a default value of 0000000. For an INTUITY System, use the
default CPID string of 0000000. Line 3 of Worksheet A already contains the value
0000000 as the CPID pad string.
Example: If you set the CPID pad string to 0000000 and the SID receives a caller
ID of 245, the SMDI caller ID information becomes 0000245.
Setting the Message Waiting Indicator
Pad String
The Message Waiting Indicator (MWI) Pad String operates on the same basis as
the CPID Pad String. As with the CPID Pad String, the SID uses a seven-digit
string, called the Message Waiting Indicator (MWI) pad string, that informs the
SID about the format of MWI information generated by an INTUITY System. The
SID uses the MWI pad string to strip off digits not required by MCI. The SID
assigns a default MWI pad string of 0000000. For an INTUITY System, use the
default MWI pad string of 0000000. Line 4 of Worksheet A already contains the
value 0000000 as the MWI pad string.
Setting the Message Waiting Indicator
Feature
The MWI feature enables the INTUITY System to activate message waiting
lamps. The SID sets the default value for this field to ENABLE, which activates the
MWI feature. If you do not want the INTUITY System to activate the MWIs, change
the field to DISABLE. Write the value on line 5 of Worksheet A.
Determining the Message Center
Interface Baud Rate
You must set the baud rate for the MCI link. The SID provides baud rate
selections of 300, 1200, 2400, and 9600 baud and sets a default of 1200 baud.
Make sure that the baud rate equals the dip switch settings on the MCI link
switch I/O card. Write the MCI link baud rate on line 6 of Worksheet A. If you plan
to use the default setting, write 1200 on the worksheet.
