2012 - Japan - Wired - Test Methods for IP Phone Terminals in category "E"

Post  Admin on Wed Nov 21, 2012 12:11 pm

Test Methods for IP Phone Terminals in category "E"
(Summary, based on JATE and JVLATE proposal - 10 March 2011)

These test methods apply to "Equipment for IP phones" which connect to the IP network and "IP phone Terminals", which connect to "Equipment for IP Phones".
Format of the certification number : EXX-XXXXXXX

Scope of Category "E"
- IP phone terminals, IP audio and visio-conference terminals directly connected to the IP network or through a router with or without NAPT function.
- IP network adapters using IP phones or plain analog phones on its subscriber's side.

Test Methods

The basic test circuit involves as a minimum an IP network simulator.
----
Article 32-2
Basic Functions

The IP Phone has to send a message to initiate a communication: INVITE
The IP phone has to send a message to disconnect or interrupt an ongoing communication:
BYE, CANCEL
Responses to the above messages: 200 OK
----
Article 32-3
Calling Functions

If the called party does not answer or is busy, the IP Phone has to end a communication attempt within 2 minutes after sending the message to initiate the communication.
If the called party does not answer or is busy, the IP Phone cannot redial more than either "twice within 3 minutes", or "15 times".
----
Article 32-4
Identification information

Identification information should be sent by an IP phone, and an IP phone should be able to request such identification.
Request message:
REGISTER
Error response, except in case of RETRY-AFTER:
401 (UNAUTHORIZED)
Error response, after a RETRY-AFTER header:
404 (NOT FOUND)
413 (REQUEST ENTITY TOO LARGE)
480 (TEMPORARILY UNAVAILABLE)
486 (BUSY HERE)
500 (SERVER INTERNAL ERROR)
503 (SERVICE UNAVAILABLE)
600 (BUSY EVERYWHERE)
603 (DECLINE)
----
Article 32-3
Congestion notification

When receiving a message notifying a congestion, an IP phone must be able to relay this information to the user.
----
Article 32-6
Emergency Calling Functions

An IP phone must be capable to call emergency numbers.
Emergency numbers:
110 Police
118 Coast Guard
119 Fire / Emergencies
----
Article 32-7
Electrical Requirements

10Base-T :
P-P Output voltage through a 100 Ohm load = less than 6.2V
100Base-TX :
P-P Output voltage through a 100 Ohm load = less than 2.1V
1000Base-T : (to be confirmed)
P-P Output voltage through a 100 Ohm load = less than 6.2V
Common Requirement:
DC voltage should not be added to the line.
----
Article 32-8
Analog Output Power

The output power of the analog signal embedded in the IP stream, when communicating with an analog telephone should be less than -3dBm (avg.) through a 600 Ohm load.
----
Article 32-9
Special IP phones

No test requirements yet.
----
Other test items
The articles below may also apply to IP phones.
Article 3
Network - Terminal Demarcation
Article 4
Prohibition of Leaked Signal Detection
Article 6
Insulation Resistance
Article 7
Prevention of Excessive Acoustic Shock
Article 8
Wiring Facilities
Article 9
Use of Radio Waves
