17、Equipment (CPE) supports on-hook signaling with or without power ringing and is able to decode data frames packaged in a Single Data Message Format (SDMF) or a Multiple Data Message Format (MDMF). Examples: 1) Calling Number Delivery (CND) may be transmitted to the CPE in the SDMF or MDMF. All CND d
18、eliveries are currently associated with power ringing. 2) Calling Name Delivery (CNAM) is always transmitted in the MDMF with power ringing. 3) (Visual) Message Waiting Indicator (V)MWI) may be transmitted to the CPE in the SDMF or MDMF. The Frequency Shift Keying (FSK) versions of (V)MWI are sent w
19、ith no power ringing, or due to limitations in pair gain systems, following an abbreviated ring. 4.2 FUNCTIONALITY Type 1 CPE shall perform three major functions. These functions include: 1) Detection of FSK signals over a range dictated by the combination of switching system, loop plant and pair ga
20、in system performance. Such detection takes place in an environment that could introduce noise and other distorting elements. 2) Decoding of individual information fields, verification of their contents and finally error checking of the entire message for accuracy. 3) Translation and presentation of
21、 the binary formatted data in a language the user can understand. 4.3 TIMING PROTOCOL 4.3.1 FSK following Power Ringing For switching features that precede FSK data with power ringing, such as CND and CNAM, the following shall apply: 1) Type 1 CPE shall be ready to receive FSK data commencing betwee
22、n 250 ms and 3600 ms following the end of power ringing. 2) Type 1 CPE shall be able to receive FSK data preceded by the ringing patterns described in ANSI Ti .401 .O24 995. 4 Copyright Electronic Industries Alliance Provided by IHS under license with EIANot for ResaleNo reproduction or networking p
23、ermitted without license from IHS-,-,-TINEIA-71 6 3) Type 1 CPE shall not log or display any type of error message for the following events: 0 Power ringing signals c 1OOms. 0 Dial Pulse signals. 0 Transients due to on-hook and off-hook transitions, except during data reception. 4) Type 7 CPE shall
24、tolerate shifts in dc voltage or voltage reversals occurring on the line prior to the start of FSK data. The timing event is illustrated in Figure 1.

25、SK without Power Ringing If the CPE supports (V)MWI, it shall be able to receive FSK data that is not preceded with power ringing, Open Switch Intervals (03) , or line polarity reversais. 4.3.3 Time-out and Resetting Capabilities If a message does not appear to end due to extended Markout (see secti
26、on 4.6.8), interference, or other similar reasons, Type 1 CPE may terminate the receive sequence of the current message 10 seconds after the end of the “on“ period of the last power ringing pattern. This provides for power conservation in battery-powered devices. If the message was not preceded by p
27、ower ringing, the CPE may terminate the receive sequence of the current message 10 seconds after the receipt of 70 bits of channel seizure signal. 5 Copyright Electronic Industries Alliance Provided by IHS under license with EIANot for ResaleNo reproduction or networking permitted without license fr
28、om IHS-,-,-TINEIA-716 4.4 FSK SIGNAL PROPERTIES 4.4.1 Frequency Type 1 CPE shall be able to detect data with a nominal SPACE frequency of 2200 Hz and a nominal MARK frequency of 1200 Hz. In addition, Type 1 CPE shall tolerate a f 1% variation of these nominal values as stated in the following: 0 217
29、8 Hz to 2222 Hz for Logical O (SPACE). 11 88 Hz to 1212 Hz for Logical 1 (MARK). 4.4.2 Signal Levels Type 1 CPE shall detect MARK between 19 mVrms and 476 mVms and shall be able to detect SPACE between 12 rnVrrns and 476 mVrms. Signal levels are measured open circuit across T message type, message l
30、ength, all parameter type words, all parameter length words and all parameter data words for the MDMF). In the calculation of the checksum, the message typel and length, as well as the parameter type and length words will be given the binary representation of their decimal value. All data words, how
31、ever, will be given the binary representation of their ASCII character set. The CPE shall tolerate distortions in the checksum stop bit that may make it appear to be a SPACE rather than a MARK. 4.6.8 Markout The CPE shall be able to tolerate any Markout (a string of mark bits following the Checksum
32、word) of up to 4.4 seconds. The CPE shall ignore any SPACE bits after the checksum. 4.7 DATA FIELD DEFINITIONS The least significant bit of the most significant byte is sent first. Each byte is preceded by a start bit (space) and followed by a stop bit (mark). 4.7.1 MDMF Date and Time parameter The
33、CPE shall decode a Parameter Type value O1 hex as the date and time parameter. The length of that parameter is 8 bytes. The most significant byte will be received first. 0 The CPE shall decode the first two bytes as the month information. The first byte of the month information is the 1 Os position
34、(Valid Range 0-1 30 hex and 31 hex). The second byte of the month information is the Is position (Valid Range 0-9 30 hex and 39 hex). The combined month information has a valid range of 1 through 12. The CPE shall decode the next two bytes (3rd and 4th) as the day information. The third byte is the
35、day information, 10s position (Valid Range 0-3 30 hex and 33 hex). The fourth byte is the day information, is position (Valid Range 0-9 30 hex and 39 hex).
