MG-COT Card [SCA-6COTA/SCA-6COTC]
5. Internal PHI-BRI and MG are connected via UDP/IP. Therefore, Routine Diagnosis is performed by Pro-
prietary Protocol procedure. System Message (33-S) is output if failure is detected.
6. System Message (33-R) is output if control packet is sent and connection failure is detected. The message
is output when timeout of control packet transmission timer occurred eight times or more continuously.
The transmission timer value is changed/modified by ASYDL command (SYS 1, INDEX 884, bit0 PHI
Re-transmission timer). After modifying the data, reset the buffer or initialize the data by ADPM com-
mand.
7. When LCR data has been assigned, LCR is activated if any failure described in conditions 5 and 6 occurs.
8. IP address and Subnet Mask of Internal PHI-BRI are LAN1 IP address (ACT) of the Telephony Server.
Port number is modified by ADTM command (default is 64000, shown as “Internal PHI-BRI”). Modified
data is automatically reflected on System Data (
Note 3
). Port number of “Internal PHI-BRI” is shared
with that of “Internal PHI-PRI”.
Note 3:
After modifying the data, initialize the data or reset the buffer by ADPM command. Data is reflected to Sys-
tem Data after this assignment.
9. Assign Quality of Service (QoS) setting for Internal PHI-BRI in ALOCL command. (LOC-ID=0) Assign
QoS of signaling packet for MG in AMGIL command, and QoS of voice packet in AMGVL/AIVCL com-
mand.
Service Conditions particular to SIP Mode
1. MG-COT Card is controlled by SP-PHI. To activate SP-PHI, it is required to register Internal PHE. To
turn SP-PHI and SP (Signaling Processor) effective, assign the following system data.
ASYDL, SYS1, INDEX 880, Bit 1 = 1 (Internal PHI-PRI/BRI is available)
ASYDL, SYS1, INDEX 880, Bit 3 = 1 (Internal PHE is available)
ASYDL, SYS1, INDEX 885, Bit 7 = 1 (SP Implementation is available)
2. MG-COT Card requests registration to SP-PHI, not to Internal PHI-BRI.
3. Accommodated location (LENS) data of Internal PHE and MPH/SP-PHI is required to be set on ALIDL
command.
4. For details on Encryption, refer to VoIP Encryption [V-27].
5. Conditions for Fault Monitoring are as follows.
• Health Check is provided between SP-PHI and MG-COT Card. If a failure is detected by the Health
Check, System Message (33-S) is output to the SP-PHI accommodated location (LENS).
• When timer timeout of control packet transmission between Internal PHE and SP-PHI occurs eight
times consecutively, System Message (33-R) is output to the Internal PHE accommodated location
(LENS).
6. SR-MGC supports MG-COT Card.
