Server: The modem must also support V.34 modulation
B6.1.4.2.4.2 If the following capabilities are implemented, support must comply with the related specification:
-
V.42 Link Access Protocol Modem error control
-
V.42 bis data compression
B6.1.4.2.5 Connection to two distinct V.90 host modems (such as 3Com and Conexant) at 40 Kbps or better. B6.1.4.2.6 If modem supports call control, media detection uses V.251.
Modems that support call control must support the ITU V.251 standard for PC-controlled call control, including:
-
DCE-controlled V.8 operation with DTE notification.
-
DTE-controlled V.8 operation ( values of 2, 3, and 4).
-
DTE-controlled V.8 bis operation.
-
Backward compatibility for media detection with terminals using V.25 signaling, for example, data calling tone and fax calling tone.
-
Backward compatibility for media detection with older modems, for example, V.32 and V.32 bis.
-
Modems must provide a means for turning on the V.8 Calling Indicator signal for originating calls. Modems must also meet requirements stated in the Videophone-ready Modem Handbook, Version 1.0, which describes the specific implementation details essential to support H.324 voice-band video conferencing.
B6.1.4.2.7 If caller ID is implemented, modem complies with ITU-T V253 section 9.2.3.1
See ITU-T V253 section 9.2.3.1 for details about correctly implementing caller ID reporting.
Note: Software-based modems are not required to capture caller ID while the system is either in ACPI S3 sleep state or resuming from S3 state.
B6.1.4.2.8 If voice modem is implemented, modem supports ITU V.253.
For a description of relevant AT commands for voice modems, see the “Voice Modem INF File Entries” listing in the Modem Devices section of the Windows DDK.
The capability for voice recording and playback (+VTX, +VRX) is not required.
B6.1.4.2.9 If fax modem capabilities are implemented, Fax—14.4 Kbps (V.17) with Class 1 (TIA-578-A) command set.
If fax modem capabilities are implemented, the fax modem must support 14.4 kilobits per second (Kbps) (V.17) with the Class 1 (ITU T.31) command set.
If fax modems include fax/data media detection (for example, T.32 +FAA command), the INF file must include the necessary registry keys, as defined in the MDK, which is provided in the Windows DDK.
Recommended for ISDN connected modems, not required.
B6.1.4.3 Controller-based modem supports additional capabilities B6.1.4.3.1 9.6 Kbps connectivity to analog modem. B6.1.4.3.2 Connection to reference modem; see test documentation for list. B6.1.4.3.3 Error control and blind dial. B6.1.4.3.4 AT commands:
ATA - accept ringing
ATD - dial
ATE - echo setting
ATH - hangup
ATI - get modem information
S0 - S0 register (0 value is to disable to accept ringing)
ATV - response code style
ATZ - reset
- - Initialize
- - Hard/Soft flow control
B6.1.4.4 PIAFS modem supports additional capabilities B6.1.4.4.1 32 Kbps (PIAFS 1.0) connectivity to PIAFS modem. B6.1.4.4.2 Connection to DC-6S in PIAFS 1.0 and to SII NS-2482-30 (dial-up). B6.1.4.4.3 If modem supports delayed/blacklisted numbers, modem generates appropriate error messages for delayed and blacklisted numbers (where applicable).
During certain international Post, Telephone, and Telegraph certification processes, modems must support the delayed and blacklisted numbers feature. For details, see European Telecommunications Standards Institute (ETSI) ETS 300 001.
For Windows compatibility, modems that support delayed and blacklisted number tables must generate end-user legible error messages to report these conditions.
Provide modem INF file drivers that translate these error messages for Unimodem and TAPI.
B6.1.4.5 ISDN modem - See B7.4. B6.1.4.6 DELETED B6.1.4.7 Global System for mobile communications or digital cellular phone support, if implemented, includes required command and protocol support
See B6.1.4.2.3
B6.1.4.8 Analog V.90 modem tested in conjunction with digital V.90 modems commonly deployed by ISPs
Modem can connect, stay connected, and successfully transfer data simultaneously
This requirement states a basic criterion for modem functionality. While operating in the default modem configuration on TIA-3800 line I01d-loop 3, the modems must be able to transfer a typical file in 40 minutes or less, simultaneously in both directions, without hanging up or otherwise aborting the transfer. Data transmission is required to be run directly on the modems without the use of an additional protocol such as Zmodem.
B6.1.4.8.1 If impairment combination 2C4 is implemented, complies with ITU-T Recommendation V.56 bis.
The analog V.90 modem subject to this requirement must meet it when connected to digital V.90 modems commonly deployed by Internet service providers (ISPs). For modems certified for operation only in countries outside of North America, the requirement is for operation on impairment combination 2C4, as specified in International Telecommunication Union – Telecommunication Standardization Sector (ITU-T) Recommendation V.56 bis. V.56 bis. specifies that the modem must be connected to an identical analog modem, rather than a digital V.90 modem.
Telecommunications Industry Association (TIA) TSB-38 provides detailed test procedures and criteria.
This requirement must be met with an overall call completion success ratio of 97 percent with a minimum of 50 iterations, and without the modem stalling in an unresponsive, inoperable state.
B6.1.4.8.3 Modem pair must be able to sustain the connection for at least 30 minutes
At no less than 90 percent of the initial connection rate, with no more than 1 retrain, using the same TSB-3800 line I01d-loop 3 specified for use under B6.1.4.
B6.1.4.8.4 E-mail: Support E-Mail: POP3 B6.1.4.8.5 Web browsing: Internet Explorer or Netscape Navigator B6.1.4.8.6 Video teleconferencing using H.323
For example, using Microsoft NetMeeting®.
B6.1.4.9 Telephony applications meet communication and performance requirements B6.1.4.9.1 System with telephony applications uses a common set of audio I/O devices for system audio and telephony applications
If the system enables telephony applications such as speakerphone, IP telephone, and so on, then for each type of audio I/O device, the same device must be usable for both system audio and telephony. For example, the same set of speakers must be usable for both system audio and speakerphone functions. When using a headset, users must not need to change plug locations when switching from, for example, listening to CD-audio to speaking on the phone.
This requirement ensures that one convenient, unambiguous I/O connector is provided for each type of audio I/O device. It does not mandate that all audio I/O is delivered to a single I/O device at all times. For example, providing system audio sounds to the speakers while simultaneously using a headset for IP telephony would not be prohibited.
B6.1.4.9.2 Telephony applications provided with a system meet industry telephony performance requirements
If the system enables telephony applications that support devices, such as speakerphone or handset telephony, using various types of connections, such as plain old telephone service (for example, through a voice modem) or IP (through a network connection), the applications provided with the system must comply with telecommunications industry requirements for such parameters as send and receive loudness, echo, and so forth.
Speakerphone applications must meet the requirements in ITU-T Recommendation P.340, Transmission characteristics of hands-free telephones. Other applications must meet the requirements in ITU-T Recommendation P.310, Transmission characteristics for telephone band (300-3400 Hz) digital telephones. For additional information for IP telephony functions, see U.S. Committee T1 Technical Report No. 56, Performance guidelines for voiceband services over hybrid internet/PSTN connections, which provides useful guidance for IP telephony functions.
Note: There is no requirement to support any ITU recommendation equivalent to TIA-3800 for the testing of pulse-coded modulation (PCM) modem operation.
B6.1.4.10 Data modem supports digital connection to support host-side V.90 operation
V.90 depends on a digital connection for the host-side modem to the public telephone network, typically using T1 or ISDN. Server modems should be designed for digital connection, to support host side V.90, where digital connections are available.
