All PJ2/PJ7/PJ4/PJ5 connectors are RF switch connectors and the part description
as below.
“INTERNAL CONNECTOR,MICRO RF SWSMT,180DEG.,JACK,RF
SWITCH,(FOXCONN),KMC1001-F007-7F”.
The main purpose of these RF switches is to verify the conductive TRX RF
performances or for debugging.
Some key performances should be verified:
i) TX Power Level
ii) Spectrum Emmission Mask
iii) RX Sensitivity
iv) EVM
v) Frequency Error
vi) VSWR

1.5.6. Driver Installation
The communication between DUT and PC is Ethernet-over-USB. Please install driver (i.e.,
dpinst.exe) on a PC first.
Two interfaces are derived when connecting USB connector to PC.
USB RNDIS : network interface
Modem Com port : AT command interface which supports baud rate: 921600 at most
In device manager, you will see an RNDIS interface and a Modem COM port after DUT boots
up completely. PC will obtain an IP address of 192.168.0.X assigned by DUT via DHCP.

Step 1
Power on DUT and then wait a while (i.e., around 20 sec).
Step 2
Make sure a Modem COM port is observed in device manager. (Please refer to section
1.1.6)
This Modem COM port (i.e., AT command interface) can simply connected through
generic UART console program such as “TeraTerm”, “putty”, etc,…
Step 3
(a.) Type shell
(b.) Type shell command: ucfg sync
Step 4
※Then a DUT reboot is required to apply the setting.
2. Prerequisite Configuration
2.1. Factory Reset
This section provides a way to execute “Factory Reset”. SDM parameter values will be
persistent throughout “Factory Reset”. “Factory Reset” is applied to Motive testing, 7Layers
OTADM testing and Field testing. It is used during the testing while “Factory Reset ” is
needed.

Command
ucfg set config wan lte ims volte rtp_rtcp_inactivity_timer_ims <value>
Description
This parameter indicates the maximum length of time a call can remain active without
any media (RTP or RTCP) traffic within a group. Each time an RTP or RTCP packet occurs
within a call, this timeout resets. The value is an integer measured in Seconds.
Example
Note: set rtcp_inactivity_timer to 300s
ucfg set config wan lte ims volte rtp_rtcp_inactivity_timer_ims 300
Get current setting from device
ucfg get config wan lte ims volte rtp_rtcp_inactivity_timer_ims
Command
ucfg set config wan lte ims volte session_timer_ims <value>
Description
The Session-Expires header value can be configured through the SESSION-EXP tag.
Session-Expires conveys the duration of the session.
SIP entities MUST be prepared to handle Session-Expires header field values of any
duration greater than 90 Seconds. Small session intervals can be destructive to the
network. They cause excessive messaging traffic that affects both user agents and proxy
servers.
More information about Session Expires and Min-Session Expire can be found in RFC
4028.
The value is an integer measured in Seconds.
Example
Note: set session_timer_ims to 90 seconds
ucfg set config wan lte ims volte session_timer_ims 90
Get current setting from device
ucfg get config wan lte ims volte session_timer_ims
Command
ucfg set config wan lte ims volte min_se_ims <value>
Description
The minimum value for session-expires value
The Min-SE header field indicates the minimum value for the session interval, in units of
seconds. The value of this element is inserted in MIN-SE header in INVITE request. The
value must be greater than 90 seconds.
More information about Session Expires and Min-Session Expire can be found in RFC
4028.
The value is an integer measured in Seconds.
Example
Note: set min_se_ims to 90 seconds
ucfg set config wan lte ims volte min_se_ims 90
Get current setting from device
ucfg get config wan lte ims volte min_se_ims

4.2. Debug Level
An introduction to enable default debug level is described in Section 5.2. Furthermore, this
subsection illustrates on how to enable a specific debug level.
4.2.1. IMS
4.2.1.1. Configuration to Enable IMS Debug Level
After applying configuration, it will store in device’s NV. However, it is different from default
debug level. That said, it will be invalid after you restore device to factory default. Step 5
gives a way to quickly check and confirm whether the device is already enabled this specific
debug level or not.
