4. MG does not supervise the condition such as Trunk failure. Therefore, MG can originate a call regardless
of Trunk failure. (As far as MG works correctly.) This condition is the same as conventional COT.
5. Internal PHI-BRI and MG is connected via UDP/IP. Therefore, Routine Diagnosis is performed by Propri-
etary Protocol procedure. System Message [33-R] 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 that is described in conditions 5 and 6
occurs.
8. IP address and Subnet Mask of Internal PHI-BRI are LAN1 IP address (ACT) of 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 1
). Port number of “Internal PHI-BRI” is shared with that
of “Internal PHI-PRI”.
Note 1:
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.
10. PAD value and Echo Canceler data assigned in APDIL/APDCL command has priority. When assigning
the Echo Canceler per location ID, use AMGVL command. PAD settings towards MCMG can be
assigned in the SETTING OF PAD.
11. Assign CODEC in AMGVL command (If AMGVL data is not assigned, AIVCL data is applied). For
available payload type/payload size, refer to Peripheral Equipment Description, Volume 1, Chapter 2,
“3.1.1 Bandwidth Required for Voice Traffic.” When both command data are not assigned, default setting
is applied (default setting is G.711- 40ms).
12. When Payload Type is specified by AMGVL/AIVCL, A
/
μ
-law setting assigned by AMGIL is applied.
System Data is not applied (ASYD SYS1 INDEX 63 bit 0 A
/
μ
-law for TSW). When A-law MG and
μ
-
law MG are connected, A-law is applied.
13. Route Number can be shared by multiple MGs.
14. Assign each LENS for MG line (0-1) and CH (Fixed to 0) in AMGIL command. (MG0: Even Number
Level, MG1: Level of MG0 + 1)
15. Guard Timer for Originating Call is performed by Telephony Server side. Assign the Timer value by
ASYD (SYS 1, INDEX 474) to change the value. Default value is 3072 milliseconds.
16. When digit conversion is required for the digits received from the public network, use ARTD, CDN66
(DC) and ACDD. A maximum of seven digits can be converted, counting from the last.
