You must purchase a feature license (E1966A-102 for release A and E1966A-103 for release B) from Agilent Technologies to enable this functionality in a licensed test application or order a special free feature license (E67066A-102 for release A and E6706A-103 for release B) from Agilent Technologies to enable this functionality in a licensed lab application. However, having the feature license E1966A-102 from Agilent Technologies does not grant you use of the Qualcomm® proprietary Release A functionality, and also having the E1966A-103 feature license from Agilent Technologies does not grant you use of the Qualcomm® proprietary Release B functionality. You must obtain consent from Qualcomm® to utilize this feature, as explained in the following statement:

Release A Concepts
1xEV-DO Release A uses 1.2288 Mcps as the spread rate and has the backwards compatibility with 1xEV-DO Release 0.
Release A supports three physical channel modes: Subtype 0 physical layer is the same as the original air interface in Release 0. Subtype 1 physical layer is very similar to subtype 0, but with support for variable rate R-Access Channel operation. Subtype 2 physical layer supports a new, high rate R-Traffic Channel along with increased data rates and support for smaller packets on the F-Traffic Channel (see
Release A Physical Layer Subtype
). Besides, Release A has a number of new applications:
-
The Multi-Flow Packet Application provides multiple octet streams that can be used to carry octets between the access terminal and the access network. See
Multi-Flow Packet Application Description
.
-
The 3G1X Circuit Services Notification Application allows cdma2000 messages to be tunneled through the 1xEV-DO air interface. Thus a dual mode mobile (cdma2000/1xEV-DO) can remain camped onto the 1xEV-DO channel and still send/receive circuit services messages. This allows the mobile to register, receive SMS messages, and receive pages from the cdma2000 system while physically listening to the 1xEV-DO network. This mode of operation eliminates the need for the Hybrid Mode where the phone must periodically tune to the cdma2000 1x to check for messages. See
Hybrid Mode
.
-
The new Multi-Mode Capability Discovery Application allows the network to discover if an AT supports such features as Hybrid Mode, Receiver Diversity or multiple TX and/or RX chains.
Release B Concepts
1xEV-DO Release B uses 1.2288 Mcps as the spread rate and has the backwards compatibility with Release 0 and Release A. To obtain increased data throughput, Release B can optionally support multiple combined RF channels. The following new protocols are added to support multi-carrier operation: Multi-carrier Forward Traffic Channel MAC Protocol, Multi-carrier Reverse Traffic Channel MAC Protocol and Subtype 3 Physical Layer Protocol (see
Release B Physical Layer Subtype
).
The new Subtype 3 Physical Layer Protocol supports multiple carriers in the forward and reverse links to increase data throughput. Moreover, with 64-QAM modulation, Subtype 3 Physical Layer Protocol supports new optional forward link rates up to 4.915 Mbps which makes the theoretical peak data throughput for three Forward/Reverse channels to be 3 x 4.915 Mbps = 14.745 Mbps in the forward Link and 3 x 1.8432 Mbps = 5.5296 Mbps in the reverse link.
Release B supports three multi-carrier multiplexing modes: No Feedback Multiplexing mode, Basic Feedback Multiplexing mode and the Enhanced Feedback Multiplexing mode. The test set only supports for the No Feedback Multiplexing mode in which each pair of forward/reverse channels operates as a stand alone pair. In the No Feedback Multiplexing mode, the feedback channels (R-DRC, R-ACK and R-DSC) for each forward channel are transmitted on a paired reverse channel using the same user long code sequences just as in Release A. See
Multi-carrier Multi-unit (MCMU)
for the Release B solution supported by the test set.
Operating Considerations
-
If a session is open in Active Cell operating mode, changing the protocol release results in a session re-negotiation (see
Session Negotiate State
). If a data connection is open, changing the protocol release results in the connection dropped with signaling. You will have to re-open the connection.

(
Lab Application Only
) The test set currently supports
Default Packet Application
when
Protocol Rel

and

Subtype 2
.
-
Not all Session Application Type are supported in all protocol release or physical layer subtypes. In Active Cell operating mode, if a protocol release that do not support a certain
Session Application Type
is selected, the selection will be rejected. See
Supported Session Application Type per Physical Layer and Protocol Release.
for which applications are supported in a certain protocol.
-
The test set currently supports protocol release A (1xEV-DO-A) and protocol release B (1xEV-DO-B) in IS-856 Test operating mode.
-
The test set does not support Subtype 1 Physical Layer protocol and Enhanced Control Channel MAC Protocol as defined in the C.S0024-A standard. See
Current Physical Layer Subtype and Associated Protocols
.
-
Due to a change in the signaling when 1xEV-DO Release A was introduced (the SCP Configuration Request contains a new field called "ATSupportedApplicationSubtypes" which was added in the 3GPP2 C.S0024 -A v3.0 standard), the test set running the E1966A Test Application version A.05.11 or E6706A Lab Application A.02.11 and earlier releases can not open a session with the 1xEV-DO Release A capable Access Terminals operating in 1xEV-DO Release 0 mode. The test set with these firmware versions cannot decode the new field and so a session failure will occur. Upgrading to newer firmware revisions will enable the test set to properly decode this parameter and will allow a session to be opened when the newer Release A phones are operating in Release 0 mode.
