General Description<\/strong><\/p>\n

Service Options 62 and 63, the source-controlled variable-rate
\nmultimode wideband speech codec (VMR-WB), provides two-way voice
\ncommunication between the base station and the mobile station using
\nthe dynamically variable data rate speech codec algorithm described
\nin this standard. The transmitting speech codec receives voice
\nsamples and generates an encoded speech packet for every Traffic
\nChannel frame*. The receiving station generates a speech packet
\nfrom every Traffic Channel frame and supplies it to the speech
\ncodec for decoding into voice samples.<\/p>\n

It should be noted that the contents of this document describe
\nall operational modes of the VMR-WB codec inclusive of the AMR-WB
\ninteroperable mode and its associated circuit-switched interworking
\nfunctions. While both Service Options 62 and 63 as well as the
\nAMR-WB interoperable mode share the same algorithmic description,
\nService Option 62 provides methods for initialization and call
\nsetup using VMR-WB modes 0, 1, 2, and 2 with maximum half-rate.
\nService Option 63 includes VMR-WB modes 4 and 4 with maximum
\nhalf-rate. Furthermore Service Options 62 and 63 shall be the
\nprimary Service Options for circuit-switched wideband voice calls
\nin cdma2000\u00ae<\/sup> terminals that support VMR- WB codec. The
\napplications and call setup using the AMR-WB interoperable mode are
\nbeyond the scope of this document.<\/p>\n

VMR-WB modes 0, 1, 2, and 3 communicate at one of four rates:
\n13300 bps, 6200 bps, 2700 bps and 1000 bps corresponding to
\nRate-Set II of CDMA systems, whereas VMR-WB mode 4 communicates at
\none of three rates: 8550 bps, 4000 bps, and 800 bps corresponding
\nto Rate-Set I of CDMA systems Note that Rate-Set I Quarter-Rate is
\nnot used.<\/p>\n

During an interoperable interconnection using VMR-WB mode 3, the
\noperation bandwidth shall be wideband and switching to other modes
\nshall not be allowed.<\/p>\n

All implementations shall meet the minimum performance
\nrequirements defined in TIA-1017-A.<\/p>\n

The algorithmic description and the operation of Rate-Set II
\ncompliant modes of VMR-WB (i.e., VMR WB mode 0, 1, 2, 2 with
\nmaximum half-rate, and 3) are identical to those described in
\n[30].<\/p>\n

*TIA-2000.3-D uses the term "frame" to represent a 20 ms
\ngrouping of data on the Fundamental Channel. Common speech codec
\nterminology also uses the term "frame" to represent a quantum of
\nprocessing. For Service Option 62, the speech codec frame
\ncorresponds to speech sampled over 20 ms. The speech samples are
\nprocessed into a packet. This packet is transmitted in a Traffic
\nChannel frame.<\/p>\n
