<When SIP mode>
MG(PRI) can be registered to either Internal PHI-PRI or SP-PHI. When registering to SP-PHI, it works using
SIP, which is called SIP mode. Here explains MG(PRI) data assignment for SIP mode. When registering to In-
ternal PHI-PRI (Proprietary Protocol mode), refer to
[1] Internal PHE Data Assignment
When MG(PRI) is used in SIP mode, MG(PRI) is registered to SP-PHI embedded in the Telephony Server. SP-
PHI is accommodated and controlled by MPH, which is also embedded in the Telephony Server. For the use of
MPH, it is required to make Internal PHE function valid. So Internal PHE data assignment is necessary. About
the procedure for the Internal PHE data assignment, refer to Vol.1, Chapter 2, "2. IP Related Basic Program-
ming" in this manual. The explanation of PHs including Internal PHE is also there.
[2] SP-PHI Data Assignment
When MG(PRI) is used in SIP mode, MG(PRI) is registered to SP-PHI embedded in the Telephony Server. So
SP-PHI data assignment is necessary. About the procedure for the SP-PHI data assignment, refer to Vol.1, Chap-
ter 2, "2. IP Related Basic Programming" in this manual. The explanation of PHs including SP-PHI is also there.
[3] MG(PRI) Data Assignment
Assign the necessary System Data for using the MG.
STEP 1: ASYD (Assignment of System Data)
SYS1
INDEX 64, b0: 0/1=
INDEX 186, b6=1 (ISDN is in service)
INDEX 187=00 (Fixed)
INDEX 474 Guard Timer for Originating Call (MTC
bit 0-3: MTC (Timer Counter)
bit 4-6: TC (Timer Class), assign 1H (64 milliseconds)
STEP 2: ASYDL (Assignment of System Data for LDM)
SYS1
INDEX 810, b2 0/1 = -/External Music-on-Hold takes precedence
This is available when Music-on-Hold by AMGIL is invalid.
Note:
STEP 3: ARTD (Assignment of Route Class Data)
Assign the route class data on Virtual Speech Channel and Virtual Signaling Channel. The following is an
example when the Virtual Signaling Channel=10 and the Virtual Speech Channel =20:
RT=10 (Virtual Signaling Channel)
RT=20 (Virtual Speech Channel)
To change the data for existing route (RT), initialize or reboot the trunk device such as circuit card, MG, or
