White Paper of LAN Phone 201 H.323 version
PSTN Debug and PSTN hidden command
Part I Introduction
This document includes two important sections: one is how to use PSTN
debug flag to analyze user’s PSTN environment when LAN Phone 201 has
erroneous PSTN incoming call detection and related LCD messages. The
other is to introduce the hidden command
[pstn]
so that user can set their own
PSTN parameters in LAN Phone 201 when default value can’t meet their
requirement.
Part II PSTN Debug Flag
1. When to use: If your LAN Phone has erroneous PSTN message on LCD,
e.g., LAN Phone can’t display “PSTN INCOMING” correctly when LAN
Phone has PSTN incoming call.
2. Usage: Please enter debug commands on TELNET command line
interface:
debug –a cpm
debug –o
After user enters commands above, please make a PSTN call, and let
LAN Phone rings for a period of time, on Telnet screen will display related
debug messages. Here is an example:
1.000:DRV --> EV_PSTN_RING(SilenceCnt:62 ,PulseCnt:50 )
0.000:DRV --> EV_PSTN_RING(SilenceCnt:66 ,PulseCnt:50 )
1.000:DRV --> EV_PSTN_RING(SilenceCnt:68 ,PulseCnt:50 )
4.000:DRV --> EV_PSTN_RING(SilenceCnt:858 ,PulseCnt:50 )
1.000:DRV --> EV_PSTN_RING(SilenceCnt:66 ,PulseCnt:50 )
1.000:DRV --> EV_PSTN_RING(SilenceCnt:66 ,PulseCnt:50 )
